CARECLEAN DEGREASER GP

Emulsifying cleaning agent for the removal of medium to heavy mineral oils and fats by

spraying and brushing.

• Emulsifying cleaning agent based on aliphatic hydrocarbons, non-ionic and anionic surface active agents. • Most universally applicable product form the series of emulsifying cleaning agents. • Suitable for the removal of most mineral oils and fats and preserving agents. • Safe for use on common metals, epoxy and zinc-silicate coatings.

Application

Cooling systems Along with the usual lime deposits, traces of mineral oils are often found in cooling systems. These oil and fat deposits hinder optimum removal of the hardness deposits when using acid cleaners (e.g.Careclean F Descalex P). In such cases, it is recommended to use an emulsifying cleaner before the acid cleaning, to remove these deposits. Careclean Degreaser GP is ideal in these cases. Spraying Careclean Degreaser GP can be sprayed undiluted onto the components to be cleaned. Tanks Careclean Degreaser GP can be used for the removal of most mineral oils and fats in loading and storage tanks. Directions for use:

Cleaning of cooling systems Fill the cooling system with an emulsion of Careclean Degreaser GP and water. Depending on the degree of contamination, 100 liters of cleaning liquid should contain 5 to 10 liters of Careclean Degreaser GP. Allow this emulsion to circulate for 12 - 24 hours at maximum temperature of 60°C. After this operation, drain the cleaning liquid and rinse the system intensively with water until the outlet water remains clear. Add cooling water treatment Caretreat 2 Diesel into the system.

Spray method Spray the objects to be cleaned until they are thoroughly dampened with undiluted Careclean Degreaser GP. Let the product act for 20-60 minutes, then rinse the objects thoroughly with water. Note: Objects subject to corrosion should not be rinsed with water; use in this case, for example, Careclean ECS Quick Dry. Cleaning of tanks Prewash Before cleaning with Careclean Degreaser GP it is recommended to prewash with hot water at approximately 60o C, except for drying and semi-drying oils where a prewash with cold water should be applied. Spray method Spray the tank with undiluted Careclean Degreaser GP until the walls are thoroughly dampened and then let the product soak in for at least 30 minutes. Rinse each tank compartment for 45 minutes with water at 60oC. For detailed instructions on tank cleaning, refer to the Marine Care Tank Cleaning Manual. A range of support equipment is also available. Properties: Undiluted at room temperature or in emulsions with water up to 6% at a maximum temperature of 60°C. It can also be used on plastic materials, epoxy and zinc-silicate coatings. Light yellow neutral liquid. Non-corrosive. Emulsifiable with water.

CARECLEAN QUICKSPLIT

A solvent based quick separating oil and grease remover suitable for use in conjunction

with oily water separators and where IMO rules are required.

* Based on aliphatic hydrocarbon solvents, selected non-ionic and anionic surfactants which are biodegradable. * Good cleaning properties and fresh odour. * Its emulsion with water and oil breaks up within a very short period. Less than 15 ppm oil remains in the water and therefore the product meets the requirements of IMO. * Suitable for the removal of most mineral oils, fats, greases and preserving agents. * Safe to use on all common metals, painted surfaces, epoxy and zinc-sillicated coatings. * Has the approval of major manufacturers for use in oil-water separators. * It fulfils TS 6850-017, edition 4 of the German military force. * High flashpoint. Application: General maintenance Careclean Quicksplit is used to clean machinery, floor plates and bulkheads in engine rooms. Tanks Careclean Quicksplit can be sprayed undiluted as a spotcleaner in tankcleaning (Marpol requirements). Directions for use:

General maintenance

For cleaning in engine rooms etc., Careclean Quicksplit is used undiluted. Dampen the surface to be cleaned and let the product act for 5 - 60 minutes. Brush the surfaces occasionally and finally rinse them thoroughly with water at 50 - 60o C. For heavier contamination we recommend Careclean HD Split.

Tanks To be used as a spotcleaner to decrease the amount of slops. Spray the surfaces to be cleaned until they are thoroughly dampened with undiluted Careclean Quicksplit. Let the product act for 5-60 minutes, then rinse thoroughly with water at 50 - 60o C. For detailed instructions on tank cleaning, refer to the Marine Care Tank Cleaning Manual. A range of support equipment is also available.

Immersion baths Careclean Quicksplit is applied undiluted at ambient temperature or up to a maximum of 55o C in a heated tank. Soak components for several hours, remove from the bath and rinse thoroughly with a waterjet. Practical hint Where an oil-water separator is installed, collect the treated bilge water in the dirty water collecting tank. After a reasonable separating time suck the bilge water from the bottom of the tank and discharge overboard through the oil-water separator. This is the best way to keep within the IMO rule limits (max. 15 ppm oil in the discharge overboard). Note: The use of emulsifying products (old style degreasers) will affect the separating properties of Careclean Quicksplit.

Properties

Clear yellow brown colored liquid. Mixture of aliphatic hydrocarbons and biodegradable surface active agents. Non-emulsifiable in water. The product is safe for use on all common metals. Special gravity : 0.792 Flash point PM CC : above 61 °C pH (1% solution) : 7.0

CARECLEAN OSD ENVIRO

� Fast acting dispersion of oils. � Contains no petrochemical solvents. � User friendly and non-flammable.

Directions For Use

Careclean OSD Enviro oil spill dispersant should be used neat and can be applied by spraying from the surface vessels. Used neat it will disperse in practice a ratio of about 2 to 4 times its own volume.

Application

Careclean OSD Enviro oil spill dispersant should be sprayed onto the oil slick using spraying equipment connected to booms with spray nozzles supplied by a pump from storage tanks. When using the product the sea surfaces should be agitated using breaker boards, boat propellers, bow wave ect. to help disperse the oil. When dealing with small spills from vessels, use hand spray pump or an eductor and fire hoses or monitor. This will mix the dispersant with seawater, and agitating the sea will help break up the oil slick as well as applying the dispersant. This technique has also proved valuable when dealing with small spills in ports and harbors between ships side, wharfs and pilings, ect. or any area which has difficult access.

Beach and Shore Application

Careclean OSD Enviro oil spill dispersant may be used for the beach and shore cleaning. Before using Carelcean OSD Enviro on beaches, the local environmental, social, economic and political consideration should be taken into account. Where application is justified, the most appropriate method of use will depend on the type of shore line, type of oil and amount. When a beach has oily liquid from a spill, it is advisable to remove as much of it as possible mechanically before using a dispersant. The amount of dispersant used is dependent on the type of oil. In cases of light to medium crude oils and light to medium fuel oils, Careclean OSD Enviro will be sufficient. For heavier oils or mousse-like residues, we advise the use of Careclean OSD. Apply the dispersant over the oil working from the low watermark upwards, before a rising tide, or in areas where it is calm or small tidal movements, use hoses to wash down the shore line to remove oil from rocks and beach.

Technical Information

The effectiveness of the oil dispersant will vary depending on the state of the oil, i.e., its pour point and viscosity at sea temperature and the time of weathering, evaporating of the lighter fractions of oil and the formation of oil-in-water emulsions which will all quickly increase viscosity and pour point and hence increase resistance to dispersion.

To be effective, it is essential to use Careclean OSD Enviro as early as possible in the cleanup operation. We recommended users of oil dispersants to read the IMO publication ‘IMO/UNEP’ Guidelines on Oil Spill Dispersants Application and Environmental Considerations’. This book gives more information on the application of dispersants. We would also like to point out that the use of dispersants in many countries is governed by local authorities or Coast Guard and permission to use the product must be sought.

Typical Physical Properties

CARECLEAN ECS SAFE Odorless, non-emulsifying degreasing agent and non-conductive

electro cleaner

• Special degreasing agent for the removal of oil and grease from machines and motor parts,

transmissions, ball bearings, gear wheels, metal parts, electrical components, etc. • Odorless. • Contains no chlorinated hydrocarbons or other harmful chemicals. • Does not emulsify in water - the polluted oil can be separated by means of an oil/water

separator. • High flash point.

Application Careclean ECS Safe can be applied with a brush or by spraying the parts to be cleaned. This product can also be used by filling an immersion bath to clean extremely dirty parts. The high flash point and the fact that it is practically odorless makes Careclean ECS Safe a pleasant and problem free product. Directions for use Immersion Baths Careclean ECS Safe is used undiluted and unheated in immersion baths. Put the parts to be cleaned in the bath and soak for several hours. Thereafter, take the parts out of the bath and spray off with a forceful waterjet. Attention: parts that need to be rust free and dry (such as electrical components) should not be sprayed clean with water but with clean Careclean ECS Safe and afterwards should be blow-dried completely because of fire risk if residues are left behind.

General Cleaning For the cleaning of dirty parts and surfaces use Careclean ECS Safe undiluted. Moisten the parts to be cleaned thoroughly with the product. Depending on the measure of dirt, soak the product for 5 to 60 minutes, brush in between. After this, rinse thoroughly with water.

Attention: parts that need to be rust free and dry (such as electrical components) should not be sprayed clean with water, but with Careclean ECS Safe and afterwards should be blow dried completely to avoid fire risk.

Attention

Cold cleaners should only be used in combination with oil/water separators. To guarantee an optimal oil/water separation, cold cleaners should never be used with greater amounts of emulsifying cleaners (e.g. of High Pressure Cleaners) if the waste is passing oil/water separators.

Properties Clear, odourless, fluid neutral degreasing agent based on among other things, high boiling aliphatic hydrocarbon. Careclean ECS Safe evaporates without residue. Careclean ECS Safe can be used on most metals, synthetic material, rubber and hardened metals, electrical components. Specific gravity (20o C) : 0.758 Flashpoint : 62o C pH : 7

CARECLEAN ACC

For manual and "in service" cleaning of Diesel Engine charge air coolers.

* Effective removal of all contaminants. * Anti corrosive properties. * No impact on cylinder oil films. * Completely combustible in the cylinder. * Dosing systems available. Application

Immersion bath

Dependant on design, the cooler is flooded with Careclean ACC or immersed in a tank full of product. The product should be heated to approx. 50°C and agitation provided with an air line. After 2 hours, drain off and flush well with water, followed by drying with an air line. Circulation method

Some designs of cooler can be circulated "in situ". In this case a pump tank and pipe system is fitted permanently or connections are provided for connecting a temporary circuit. The system should be filled with Careclean ACC and circulation carried out for 2 - 4 hours at a temperature of upto 50°C. After cleaning the cooler should be thoroughly flushed with fresh water and dried with an air line. Note: Both cleaning methods benefit from heat of up to 50°C and cleaning times can be reduced or extended dependant on temperature and degree of fouling. Direct injection

Careclean ACC has the approval of the majority of major manufacturers for use either in their own design of "in service" cleaning system or other recognised systems provided by suppliers. Injection systems

Marine Care offer a range of newly developed easy to operate manual systems. Directions for use

Regardless of the type of "in service" system used, Careclean ACC should be dosed at the ratio of 2 parts water added to 1 part product (in that order) and well mixed for immediate use. If the emulsion is left standing for up to 5 minutes its composition will change and effectiveness

reduced. It is most important that 5 - 10 minutes after dosing the solution, injection with fresh water only is repeated using double the total volume of the first solution to flush off the chemical residual which contains the "solved" contamination. Failure to do this will result in a "sticky cooler" which will foul very quickly. Turbo blowers

The water washing of the air side of turbo blowers has been accepted for many years. Most manufacturers provide nozzles and dosing pots to inject water into the volute casing after the inlet filters. These systems can be utilised with a solution of Careclean ACC at the same ratio of 2 parts water mixed into 1 part product and dosed via the water wash system. Note: When cleaning turbo blowers "in service" follow the equipment manufacturers instructions regarding engine load and/or blower revolutions during the procedure. As with normal water washing, do not attempt to clean a badly fouled blower as resultant removal of deposits could cause imbalance of the rotor. The principle to follow is prevention not cure. Injection systems

Marine Care can give advise on modifications to existing equipment or retrofit packages. For further details refer to the equipment information sheet. Properties

Light yellow coloured neutral fluids, which emulsify with water and are safe in contact with all metals. Specific Gravity (20°C) : 0.915 Flash point PM CC : 87 °C For detailed information on safety and health, please refer to Material Safety Data Sheet and / or

- Scale & Rust Removers -

CARECLEAN F DESCALEX P Inhibited acid cleaning powders for removal of water scale and rust deposits from water

systems. * Inhibited to prevent acidic attack on surfaces to be cleaned. * Safe on rubber, plastic and jointing materials. * Easy to handle. * Suitable for most common metals except zinc, aluminium and galvanised materials. Application: Careclean F Descalex P is an inhibited sulphamic acid based products suitable for the cleaning of boilers, condensers, evaporators, butterworth heaters and pipe systems etc. Directions for use: General 1. We recommend that a preliminary test is carried out on samples of the original scale or

deposit in order to select the most suitable acid cleaner and optimize concentration and temperature conditions.

2. When a boiler is soiled with light oil deposits, or if silicates and/or calcium sulphates are present, boiling out with Careclean Alkaline Extra is recommended.

3. If heavy mineral oil deposits are present in a boiler, a preliminary treatment with an emulsifying cleaner, like Careclean HD Split or Careclean HD is recommended.

4. If heavy oil deposits are present in cooling systems a preliminary cleaning with the emulsifying cleaning agent Careclean Degreaser GP is necessary.

Circulation Method

1. If present, remove zinc, aluminum, galvanized steel components before commencing the

cleaning operation. 2. Before cleaning with Careclean F Descalex P solution, we recommend thoroughly rinsing

with water. This will partly or completely remove loose sludge, scale, etc.

3. Depending on the nature of the scale and degree of contamination, it is recommend to use a cleaning solution with a concentration of 3 - 10 kgs Careclean F Descalex P per 100 liters of water. This solution can best be prepared by continuously stirring the powder into warm water.

4. Solutions of Careclean F Descalex P may be heated to a maximum of 60o C, which will result in a quicker cleaning process.

CARETREAT 1 EVAPORATOR Neutral, liquid product for the prevention of scaling in sea water evaporators

* Product developed as part of the Marine Care Water Treatment Program. * Prevents scale formation at temperatures up to 160° C. * Reduces foaming and maintains optimum plant performance. * Environmentally safe product with approval for use when distilling to potable water tanks. Introduction In the production of distilled water in seawater evaporators, there are many conditions which can cause scaling. In the evaporator, the seawater is heated to the required temperature and is then partially evaporated at atmospheric or low pressure; it then condenses and is collected as distillate. Since, however, the seawater contains large quantities of salt in solution it is understandable that the heating and evaporation will very rapidly lead to scaling of the heat transfer surfaces. The scale deposits build up and lower plant efficiency by severely impairing the transfer of heat. This in turn considerably reduces the output. Scaling is prevented by the use of Caretreat 1 Evaporator. If the product is used as part of the Marine Care Water Treatment program, production is monitored as part of a "Water Management" system which includes useful information on maximizing plant efficiency. Directions for use Caretreat 1 Evaporator is diluted with seawater andfresh water and is continuously injected into the evaporator. A dosage of 30 ml per ton of distillate is recommended for the prevention of scaling in seawater evaporators. The total dosage of Caretreat 1 Evaporator to be used depends on the capacity and the operating conditions of the evaporator. The product should be injected via the evaporator inlet or the salt water supply line. The normal procedure is to use a dosing tank containing sufficient ready diluted Caretreat 1 Evaporator for 24 hours continuous operation. Note: For the gradual removal of existing scale deposits, at least twice the normal dose must be used. Remove deposits of more than 2mm, with Careclean HD Descalex L.

Dosing systems Marine Care can supply a gravity dosing system kit which includes a dosing tank, flow meter, pipes, valves and all fittings. Properties Light brown colored, neutral liquids. Miscible with salt and fresh water in any proportion. Odorless, non-flammable. Contains no volatile components; in practical terms, non-toxic when ingested in a single dose. Remains fully effectively up to 160o C. Does not corrode stainless steel, carbon steel, copper alloys, glass rubber, plastics, painted surfaces, aluminium and aluminium alloys. Specific gravity (20oC) : 1.10 Flash point : None pH (1% solution) : 7 For detailed information on safety and health, please refer to Material Safety Data Sheet and / or

CARETREAT 2 DIESEL

Diesel engine cooling water corrosion and scale inhibitor in liquid form, suitable for "closed

circuit" systems

* One of the five Marine Care Water Treatment Products. * Suitable for slow, medium and high speed engines. * Effective inhibition of ferrous and non ferrous metals. * Prevents scale and sludge build ups. * Safe to use when cooling water is heat source for potable water systems. * Has approval of major diesel engine manufacturers. * Does not encourage bacteria in system. * If the chloride level is below 100 ppm CI, also aluminium in normal rated engines is protected.

Application Caretreat 2 Diesel is a nitrite, borate and polymer based corrosion inhibitor with a suitable buffer to ensure stable pH conditions. The formula has the U.K. Department of Trade approval for use in cooling systems incorporating a fresh water generator producing fresh water for drinking purposes. Recommendations for cooling water treated with Caretreat 2 Diesel : Nitrite 1200-3000 ppm NO2 Chloride max. 100 ppm CI Hardness max. 180 ppm CaCO3 pH 9,0 - 10,0

Directions for use Caretreat 2 Diesel is used in a dosage of 1200 - 3000 mg/l nitrite (NO2), dependent on the chloride level and engine type, please refer to the engine manufacturers instructions on recommended nitrite ranges: Chloride concentration Initial dosage Nitrite range 0 - 50 ppm CI 6 ltr/m3 cooling water -1500 ppm NO2 50 - 100 ppm CI 6-8 ltr/m3 cooling water 1600-2000 ppm NO2

Starting with the treatment of a system, the nitrite level must be kept at the higher nitrite level of the corresponding chloride concentration by testing and dosing daily. If the system is passified the testing frequency and dosing can be reduced till once a week at minimum. Always add Caretreat 2 Diesel at a point where circulation is high. Most modern systems header tanks are purely for expansion and have little or no circulation. Also they are often fitted with an internal baffle which can have the effect of trapping treatment and subsequent difficulty in obtaining the correct levels. The majority of loss in treatment levels will be due to leakage and subsequent dilution by make up water (distilled water should always be used). We advise testing of the Caretreat 2 Diesel level with the Marine Care nitrite control test, or via the conductivity with the BWT Electronic testkit. Dosing system A compact electronic dosing pump and tank unit is available from Marine Care for direct injection to the cooling system. For further details refer to Marine Care equipment information.

Remarks On new buildings or overhauled systems, follow engine manufacturer's advice in conjunction with Marine Care. If changing to Caretreat 2 Diesel from nitrite borate based products of another make, start dosing Marine Care product using Marine Care tests. Caretreat 2 Diesel will slowly remove sludge and other residues during first month. This can result in slightly cloudy water which will clarify after draining small quantities of water and as make up is added, leaving system extremely clean. It is not necessary to drain existing coolant completely unless inspection has shown excessive contamination. Marine Care can give expert advice on cleaning systems.

Properties Caretreat 2 Diesel is a pale yellow liquid, completly soluble in water. It is based on nitrite and borate in combination with specific inhibitors, organic dispersants and a pH buffer. Compatible with anti-freeze products based on monoethylene glycol. Specific gravity (20oC) : 1.225 pH (1% - solution) : 9,5 - 10 Flash point : none For detailed information on safety and health, please refer to Material Safety Data Sheet and / or

CARETREAT 3 BOILER

Advanced organic boiler water treatment to control ph, corrosion, scale and sludge.

* One of the five Marine Care Water Treatment Program Products. * Advanced polymer technology. * Organic corrosion control. * Simple accurate testing. * Prevents caustic corrosion. * Low "Totally Dissolved Solids". * Effective scavening of nominal oxygen prescence. Introduction Caretreat 3 Boiler has been developed to meet the demands for a modern, practical boiler water treatment. Caretreat 3 Boiler is a dark brown liquid based on neutralized organic acids, pH, corrosion, scale and sludge conditioners. The neutralized organic acids remove nominal oxygen presence and inhibit the boiler corrosion forming an organic iron compound. The correct pH is maintained by a unique blend of low molecular weight compounds which avoid pitting corrosion caused by chlorides. Use of these compounds also avoids "under deposit" corrosion which is caused by excess alkalinity in conventional treatment. A blend of advanced polymers stops the formation of scale and maintains clean surfaces in the boiler. These conditions are maintained with a low total solids level, avoiding heavy sludge, making blow down of the boiler more efficient. Application Marine Care Water Treatment Program Suitable for all auxiliary boiler plants on motorships including dual pressure boiler primary systems of up to 50 Bar.

Standard Water Treatment This program is suitable for boilers up to 20 bar, results we strongly recommend continuous dosage into the feed system, via a dosing pump and tank unit.

Directions for use

Marine Care Water Treatment Program If the product is used as part of the Marine Care Water Treatment Program, it must be continuously dosed in conjunction with Caretreat 4 Condensate using the Marine Care dosing pump / tank unit. For further details on dosing equipment refer to equipment information sheet. Standard Water Treatment Caretreat 3 Boiler can be added directly to the feed water. We strongly recommend this and this is achieved by using a dosing pump. Control limits Standard Water Treatment The boiler water must meet the following conditions: p-Alkalinity : 100-200 ppm CaCO3 Chloride content : max. 200 ppm Cl pH : 10.5 to 11.0 Conductivity : 400 to 2000 uMho Intial dosage Caretreat 3 Boiler is dosed at 0,4 litres per metric ton boiler water. Allow the boiler water to be conditioned for 24 hours and then carry out a p-alkalinity test. Adjust product dosage as necessary to obtain a p-alkalinity of 100 - 200 ppm. At the same time determine the chloride content. If the chlorides are too high, give the boiler a top and bottom blow down in a ratio in time 2 to 1.

Daily dosage Recheck p-alkalinity and increase dosage of Caretreat 3 Boiler if necessary to maintain pH or p-alkalinity level. A minimum of 0,2 ltr/day should be dosed to maintain correct treatment levels in conjunction with regular top and bottom blown down. This dosage can vary according eg. size of the boiler system, make up water quality etc.

Properties Caretreat 3 Boiler is a dark brown liquid containing neutralized organic acids, pH, corrosion, scale and sludge conditioners. After using the treatment the boiler water will be clear and straw coloured.

CARETREAT 4 CONDENSATE An organic oxygen scavenger and corrosion inhibitor for feed, steam and condensate systems

* One of the five Marine Care Water Treatment Program Products. * Environmentally safe, non-toxic product. * Unique single product for control of corrosion throughout the condensate system. * Simple, accurate testing. * Effective under all operating conditions. * Protects boiler surfaces by forming an iron tannate film. Introduction Caretreat 4 Condensate is an oxygen scavenger based on neutralized organic acids and a blend of volatile/neutralizing amines. It is normally used only in conjunction with Caretreat 3 Boiler as part of the water treatment program. It removes oxygen efficiently in open feed systems and gives effective corrosion inhibition of boiler/exhaust gas economizer system surfaces by converting Fe203 (rust) to an organic iron compound. It also protects copper based metals. The amines pass over with the steam and have the dual function of elevating the pH of the steam/condensate and putting a protective micro film on the system pipe work. Acidic condensate is the result of carbonic acid (H2C03) being formed as CO2 is released in the steam. The use of Caretreat 4 Condensate prevents corrosion by carbonic acid on live systems. Its filming properties also reduce corrosion on shut down lines, when moisture and oxygen are present. Directions for use Caretreat 4 Condensate is dosed at a rate which maintains a pH of 9.0 to 10.0 in the condensate returns. Oxygen entrainment largely depends on Hotwell temperatures and if these are maintained at above 80o C the condensate pH range of pH 9.0 to 9.5 is adequate. If Hotwell temperature control is erratic and averages less than 80o C, tighter control is necessary and condensate returns should be kept in the range pH 9.5 to 10.0. It is not necessary to carry out oxygen or product residual tests.

Initial dosage Caretreat 4 Condensate is initially dosed at 0,2 ltr/m3 boiler water. Systems showing signs of corrosion should be dosed at up to .07 ltr/m3 boiler water for the first few days in order to passivate all metal surfaces.

Daily dosage rates After initial dose, start metering at a minimum of 0.4 ltr/24 hours continuously and adjust to obtain correct condensate pH. Dosing system Caretreat 4 Condensate must be dosed continuously in conjunction with Caretreat 3 Boiler in a metering pump/tank unit, discharging directly into the feed system and/or the exhaust gas economizer circulating pump discharge. It must NEVER be slug dosed to a running system via a Hotwell or by-pass feeder. For further details on dosing equipment refer to the equipment information sheets.

CARETREAT 5 SEAWATER Disperses marine growth and reduces corrosion in sea water cooling systems, tanks and sea

water systems

* Prevents and controls marine growth in once-through sea water cooling systems. * Protects system from corrosion by filming properties. * Being biodegradable and not oil-based, its use does not contravene regulations limiting oil in discharge water. * The formula is approved by the U.K. Department of the Envirement for use at a dose rate not exceeding 8 ppm for sea water pipelines feeding evaporators producing water for potable purpose * Has clearance of major international environmental control departments for discharge into harbour and sea. * Empty tanks remain protected for several days. Introduction Caretreat 5 Seawater has been designed to effectively stop the development of micro organisms, shell embryo, bacteria and plant life commonly found in sea water. Most fouling of ships systems is primarily the result of microscopic organisms colonising in the pipework, attracting growth of larger lifeforms and giving anchorage to sand and silt. Partial blockage of heat exchanger tubes reduces flow, resulting in local overheating and subsequent scaling from hardness salts. Directions for use

1. Sea water cooling systems

The product is injected into seachests to give a concentration of 6 ppm over a period of 1 hour every two days that the vessel is in shallow water. This period is sufficient to remove the foulants before they have anchored and started adult development, at which time they are extremely difficult to control. To achieve these dosing rates, 0,6 litre of Caretreat 5 Seawater must be injected each second day for each 100 tons/h of flow into the seachest(s) (=0.006 litre/ton). Vessels which are continuously coastal must inject Caretreat 5 Seawater at he same rates every third day.

Dosage instructions

Example : system of 250 tons/h.

Dosage method Using the Caretreat 5 Seawater Dosing System to high and low boxes via stop valve and non-return valve. Extension tube mounted inside box, out to grid. For further details refer to the Marine Care equipment information sheet. Dosage routine A. Calculate amount of Caretreat 5 Seawater for each dose. i.e. 250 tons per hour x 0.006 litre = 1.5 litres/dose. B. If using a dosing system which requires dilution of Caretreat 5 Seawater with water never add water to the product. Always mix the product into the water, stirring continuously. C. On approaching shelf or coastal area, open discharge valves to operating chest and operate system for 1 hour. D. Close system valves. E. Make note of date and which box dosed. F. If changing to high level suction remember to dose to the correct box. G. When leaving area (dockside, estuary, coast or shelf area) continue dosing on 2 day cycle so that last dose is after clearing shallow waters.

2. Tanks Inject Caretreat 5 Seawater into sea water at 45 - 130 ml per m3 water capacity.

3. Pipelines Dose at 100 ppm by injecting 80 x D-ltrs per kilometer of pipeline. (D = pipe diameter, in meters). If fresh water is used for either applicaion lower concentrations may be used. Properties Cloudy yellowish-brown aqueous liquid containing dispersants with filming properties. In concentrati-ons less than 10 % miscible with water. Specific gravity (20oC) : 0.99 Flash point PM CC : above 100oC pH (1 % solution) : approx. 7

CARETREAT POTABLE WATER TREATMENT

• Prevents corrosion in potable water systems • Prevents rusty appearance of water • Stabilises excess hardness • Economical, easy to dose liquid • NON toxic (less than 10 ppm SiO2)

INTRODUCTION

Caretreat Potable Water utilises polymer technology in combination with silica to provide a protective film on system surfaces, avoiding corrosion and scale formation. The product can be injected into the discharge lines of the fresh water generator and/or reverse osmosis plant to avoid the problems of corrosion caused by the acidic distillate from these plants. If these lines are protected, the product is injected directly into the fresh water pumps’suction manifold. If a high percentage of shore water is used and the tanks are oxidising, the product must be slug dosed into the tanks prior to taking water.

APPLICATION

Dosage instructions

Initial dosage: Inject the product at a rate of 50 ml. per m3 water. Use the same rate (50 ml/m3 water) for slug dosing tanks.

Continuing dosage: Within a short period water outlets on the vessel will become clear. At this time, reduce the dosage to 25 ml. per m3 water.

Dosing system operation: To achieve the initial 50 ml/m3 water the following routine must be carried out :

a. Calculate average daily potable water consumption from vessel records. b. Using rate for initial dose (50 ml/m3 water) calculate 24 hours requirement. c. Partly fill dosing tank with water and add the calculated volume of product, for each 24 hours of injection. d. Fill the tank to capacity, mix well and start dosing.

Example:

For 20m3 per day : initial dose Pump : PWT dosing unit Max. output : 10 litres/hr. Tank capacity : 60 litres

Dilution of product : 60 : 1

* Add 1 litre of POTABLE WATER * Fill the tank to capacity (60 litres) * Set pump stroke and cycles to discharge 60 litres/day * Refill every day.

- Fuel Oil Treatment -

CARETREAT SLUDGE

Caretreat Sludge is an oil soluble and self dispersing fuel oil treatment primarily

formulated to combat problems in the pre-combustion stage with oil used in marine

diesel engines and boiler plants.

• Dissolves and disperses existing sludge. Dispersants maintain the combustible

constituents in suspension throughout the oil. • Prevents polymerization and inhibits asphaltenic sludge formation and paraffin wax

separation resulting in less clogging of fuel filters and fuel injector fouling. • By dispersion of sludge, Caretreat Sludge will counteract the effects of stratification

(layering) of incompatible fuels, thereby promoting a homogenous uniform viscosity. • Will break water/ oil emulsions and promote separation of dispersed water from heavy

fuel oil, thereby improving purifier efficiency. • Corrosion in tanks and fuel lines is reduced by effective corrosion inhibitor

incorporated. • Improved conditions in the pre-combustion stage will result in an improvement of

some post combustion problems such as a more complete combustion, less carbon formation, a decrease in deposit forming sodium, less smoke and soot.

Application

Caretreat Sludge is easy to use. The required amount is introduced into the bunker tanks simply by pumping it through the sounding pipes prior to oil bunkering. The turbulence created by the subsequent bunkering will, together with the incorporated dispersants, ensure complete mixing and further distribution of the treatment uniformly throughout the fuel. Dosages

To obtain the benefits of the chemical treatment to the entire fuel oil system it is necessary to dose the product in the most appropriate ratio depending upon the nature and severity of the problem. If Caretreat Sludge is not used regularly an initial dosage of 1:4000 should be used for breaking up and dispersing existing sludge. For counteracting the effects of incompatible fuels (stratification) a dosage as high as 1:2000 may be necessary. Properties

Clear yellow liquid with a characteristic smell, containing solvents, special detergents and dispersants. Contains no chlorinated solvents or other harmful ingredients.

CARETREAT COMBUSTION

The latest development of a fuel oil treatment acting as a combustion improver, carbon

catalyst, ash deposits modifier and smoke suppressant for diesel engines and boilers.

* Increases combustion efficiency. * Reduces carbon buildup effectively in combustion zones. * Inhibits the formation of carbonaceous ash deposits in exhaust and scavenging ports. * Minimising low temperature corrosion by effective catalysts inhibiting conversion of

sulphur dioxide to sulphur trioxide. * Reduces piston ring groove and piston fouling resulting in longer life of piston rings and

cylinder liners. * Reduces ash deposit formation in turbo-chargers and on exhaust valves. * Decreases smoke emissions. * Fuel conditioning components stabilizes fuel viscosity, preventing sludge formation in

tanks, filters, preheaters. * Improves water separation in settling tanks and separators.

Application

Caretreat Combustion is a concentrated product, especially formulated to treat heavy fuel oil in diesel engines and boilers. Dosing Dosage point location varies depending on engine/boiler fuel system layout. The most efficient and economical method is obtained with a metering pump, dosing the additive into the suction side of the booster pump (for diesel engines) or into the burner feed line (for boilers). Alternatively the additive may be dosed directly to the day tank prior to refilling or directly to the bunker tanks. Dosage rates are depending upon engine characteristics, operating conditions and quality of fuel oil. A CCAI (Calculated Carbon Aromaticity Index) number exceeding 840 indicated a poor fuel oil quality which justifies the use of a chemical fuel oil treatment to counteract the effects hereof. Typical dosage rate varies between 1:1000, 1:6000 and 1:12000. Consult your local Marine Care Service Engineer for recommendations of the dosage rate based on specific problems and requirements onboard.

Properties

Browns liquid containing special solvents, emulsion breakers, anti-oxidants, anti-corrosive agent, combustion catalysts, inhibitors, dispersants and ash modifiers. It is easily soluble in all types of fuel.

CARETREAT ECONOMIZER Liquid to prevent soot deposits in exhaust gas boilers at low temperature. * Effective above 200 °C * An easily dosed liquid * Complete coverage of entire exhaust gas unit * Greatly improved heat transfer * Neutralises sulphuric acid * Reduces corrosion and fire risk Introduction Todays main propulsion units have low exhaust gas outlet temperatures. This is due to increased engine and turbo blower efficiency. Lower gas temperatures are also the result of running at reduced power. The low temperature and reduced gas volume gives increased soot deposition and subsequent corrosion. The increased deposition greatly reduces the thermal efficiency of the economizer. As "dew point" is often reached in the unit, causing the generation of sulphuric acid, the corrosion process is greatly accelerated. Caretreat Economizer is a specially developed liquid which is easily dosed into the system, using a special Marine Care injection unit. The special air assisted nozzles create a fine mist so that the liquid vaporises on contact with the hot gas. The vapor mixes intimately with the exhaust gases and the active material is dispersed throughout the system in microscopic particles. These tiny particles have an extremely large "active surface area" and being light, remain in the gas fully dispersed. This ensures that all parts of the economiser are covered efficiently. Caretreat Economizer catalyses the post combustion process, resulting in modified soot particles which are dry and non adherent. The resulting deposit is more friable and can be more easily removed by the action of the sootblowers.

Directions for use Caretreat Economizer is designed to prevent major build ups of soot in service.

Dosage instruction 1-2 litres of Economizer is required for every 1000 m2 of heating surface area. This amount should be increased / decreased dependant on economizer design and fuel consumption.

Dosage period Caretreat Economizer should be injected daily or twice daily after sootblowing. Dosing equipment The product must be dosed via the specially developed Marine Care injection unit which is made of materials suitable for prolonged contact with Caretreat Economizer. For further information please refer to the Marine Care equipment information sheet. Injection points In most cases a single injector can be put into the exhaust systems immediately after the turbo charger gas outlet. Marine Care engineers will inspect and make detailed recommendations for exact positioning. Properties Yellowish coloured neutral product containing special metal salts. Fully miscible with water. Specific gravity (20°C) : approx. 1.19 kg/ltr. Flash point : none pH (1% solution) : approx. 7

CARETREAT VALVES A Post-Combustion fuel ash modifier very efficiently reducing high temperature

corrosion causing premature exhaust valve failure in low-speed and particularly

medium-speed diesels

* Reduces deposits caused by combinations of sodium, vanadium and sulphur in

combustion zones, turbochargers and especially on exhaust valve seats and valve stems.

* Increasing exhaust valve life substantially. * Raising fuel ash sinter and melting point temperatures above the normal engine

operating temperatures. * Reduces turbocharger fouling. * Reduces high temperatures fused salt corrosion of valve alloys. * Modifying vanadium compounds to non-adherent ash forms. * Converts crystalline ash forms to light and friable, easily exhausted fuel ash. * Prevents vanadium from converting sulphur dioxide to sulphur trioxide catalytically. * Improves combustion. Application Caretreat Valves has been formulated primarily for use in 2-cycle and 4-cycle medium speed diesel engines which are highly turbocharged and in which premature exhaust valve failure is a frequent problem. Dosage Dosage point location varies depending on engine fuel system layout. The most efficient and economical dosing method is obtained with a metering pump, dosing the additive as near to the oil injection point as possible, f.inst. to the suction side of the booster pump. Dosage rates are depending upon engine characteristics, operating conditions and especially the quality of fuel oil. Consult your local Marine Care Service Engineer for recommendation of dosage, etc. based on specific problems and requirements onboard.

Guide for approximate dosage rates:

The combination between the various constituents changes with each bunker supply. It is therefore imperative that dosages are set for the worst case, viz. the highest value of any of the above fuel oil constituents.

Properties Caretreat Valves is a light brown coloured liquid containing oil soluble organo-metallic compounds, special solvents, emulsion breakers, anti-oxidants, anti-corrosive agents, combustion catalyst and dispersants. Compatible with all types of fuel oil.

CARETREAT SOOT Vapourising powder for the reduction of deposition and corrosion in boilers.

* Modifies soot making it less adherent. * Reacts with sulphur, avoiding sulphuric acid formation. * Reduces vanadium slagging. * Enhances soot blowing. * Reduces fire risk in uptakes. APPLICATION Caretreat Soot is suitable for all types of oil fired boilers. It is injected into the combustion chamber and vaporises. The vapor mixes with the combustion gases and reacts with sulphur oxides, which remain as sulphur dioxide (SO2) instead of sulphur trioxide (SO3) which normally combines with water (H2SO4). The modified sulphur oxides combine with vanadium compounds and prevent the formation of harmful low melting point sodium vanadyl vanadates. Caretreat Soot greatly improves sootblowing efficiency and makes boiler cleaning an easier task. DIRECTIONS FOR USE

Dosage Initial dosage for dirty boilers should start at 130 gr. per m³ fuel burnt in 24 hours. The calculated dose should be divided into 3 equal parts and dosed at 8 hour intervals. As conditions improve the dosage can be progressively reduced to a minimum of 30 gr. per m³ fuel burnt in 24 hours. Once every 24 hours soot should be blown at least 1 hour after the last injection of Caretreat Soot. If a boiler has never been treated and is very dirty, double the initial figures can be used for the first 2 weeks. Injection

An air operated powder injector can be supplied by Marine Care. Its discharge tube should be put through a combustion chamber sighting orifice or a special dosing access point. If possible, the injection should be changed frequently to assist distribution throughout the boiler.

CARECLEAN NEUTRAL HCF Universal neutral liquid degreaser for the removal of vegetable oils and animal oils and fats

from zinc-silicate coated tanks.

• Neutral cleaning product based on highly efficient dissolving and low foaming nonionic surface active agents.

• Expecially developed for the removal of vegetable, animal and mineral oils as well as fats where cleaning with Careclean Alkaline Extra or Careclean Alkaline is not possible.

• Suitable for cleaning tanks coated with zinc-silicate and all common metals. Application 1. Careclean Neutral HCF can be used for the removal of vegetable and/or animal oils and fats and light mineral oils in aluminium and/or zinc-silicate coated tanks. 2. Careclean Neutral HCF can be used as an after treatment agent in hydrocarbon free cleaning operations where cleaning has been carried out with e.g. Careclean Degreaser HD or Careclean Degreaser GP. Directions for use Cleaning of tanks Prewash before cleaning with Careclean Neutral HCF it is recommended to prewash with hot water at 50°C. For drying and semi-drying oils a prewash with cold water should be carried out immediately after discharge of cargo to retard oxidation and hardening of oil residues. Recirculation method A chemical solution is prepared in an empty slop tank or one of the after tanks near the pump room, circulated via the automatic tank washing system pump and heater to the tank to be cleaned, wherefrom the solution is returned to the chemical solution tank via the stripping line. Usually it is not possible to recirculate the chemical solution through the tank washing system heater (to maintian solution temperature) without making a temporary connection between the chemical solution tank and the tank washing pump. Capacities of solution tank, pipeline and pumps etc. should be calculated carefully to ensure sufficient volumetric quantity for a continuous recirculation.

Depending on size and condition of tanks to be cleaned and quantity of chemical solution, a drawback in this method is that usually only 3 (three) tanks can be cleaned with one solution after which a fresh solution should be made and heated before cleaning can continue. Depending on the degree of contamination Careclean Neutral HCF is circulated as a 2-3% solution for a periood of 2-6 hours. The water temperature should be approx. 20-60 °C. After the circulation period rinse thoroughly with water.

Application

Cooling systems Along with the usual lime deposits, traces of mineral oils are often found in cooling systems. These oil and fat deposits hinder optimum removal of the hardness deposits when using acid cleaners (e.g.Careclean F Descalex P). In such cases, it is recommended to use an emulsifying cleaner before the acid cleaning, to remove these deposits. Careclean Degreaser GP is ideal in these cases. Spraying Careclean Degreaser GP can be sprayed undiluted onto the components to be cleaned. Tanks Careclean Degreaser GP can be used for the removal of most mineral oils and fats in loading and storage tanks. Directions for use:

Cleaning of cooling systems Fill the cooling system with an emulsion of Careclean Degreaser GP and water. Depending on the degree of contamination, 100 liters of cleaning liquid should contain 5 to 10 liters of Careclean Degreaser GP. Allow this emulsion to circulate for 12 - 24 hours at maximum temperature of 60°C. After this operation, drain the cleaning liquid and rinse the system intensively with water until the outlet water remains clear. Add cooling water treatment Caretreat 2 Diesel into the system.

Spray method Spray the objects to be cleaned until they are thoroughly dampened with undiluted Careclean Degreaser GP. Let the product act for 20-60 minutes, then rinse the objects thoroughly with water. Note: Objects subject to corrosion should not be rinsed with water; use in this case, for example, Careclean ECS Quick Dry. Cleaning of tanks Prewash Before cleaning with Careclean Degreaser GP it is recommended to prewash with hot water at approximately 60o C, except for drying and semi-drying oils where a prewash with cold water should be applied. Spray method Spray the tank with undiluted Careclean Degreaser GP until the walls are thoroughly dampened and then let the product soak in for at least 30 minutes. Rinse each tank compartment for 45 minutes with water at 60oC. For detailed instructions on tank cleaning, refer to the Marine Care Tank Cleaning Manual.

CARECLEAN VOYAGE (SEACLEAN)

Strong emulsifying cleaning agent for the removal of heavy crude oil, soot, ashpalt and carbon

black stains, by direct injection, Voyage method, spraying and/or recirculation-METHOD.

* Strong emulsifying cleaning agent based on aliphatic/aromatic hydrocarbons and non

ionic/anionic surface active agent. * Especially suitable for the direct injection and Careclean Voyage method, as product contains

a high percentage of surface active agent. * Washing times are reduced by 50% and only slight agitation is normal required. * The product is safe to use on common metals.

Application

Tanks Careclean voyage can be used for the removal of most mineral oils and fats in cargo and storage tanks. Double Bottom Tanks Careclean Voyage can be used for cleaning and gas freeing of double bottom tanks, using the rolling motion of the ship which normally provides sufficient agitation.

Directions of use Cleaning of cargo and storage tanks. Prewash Before cleaning with Careclean voyage, it is recommended to prewash tanks with hot water of approximately 50° C except for crude oil drying and semi-drying oils where a prewash with cold water should be applied.

Direct Injection Method For Cargo Tanks: Undiluted Careclean Voyage should be injected at a predetermined rate into the pressure side of the automatic tank cleaning system line on deck, by means of an airoperated drum pump. Usually an injection rate of 0.1 - 0.2 litre Careclean Voyage per 100 litres of tank wash water is sufficient. Cleaning time 2-6 hours. Subsequently rinse with water.

Hand Spraying Method Spray undiluted Careclean Voyage directly on to bulkheads, frames, stringers etc. using an air-operated drum pump connected with a delivery hose and hand spray gun. After a pre-determined reaction time, tanks should be rinsed with water using the automatic tank washing machines. For spot cleaning only use hand held hose for rinsing, for instance fire hose with nozzle. Hand spraying method is the most economical system in terms of chemical consumption but requires tanks being gasfree enabling men to enter tanks. However, hand spraying method has a practical time limitation depending on tank sizes, i.e. total tank surface to be sprayed. Recirculation method A chemical solution is prepared in one of the after tanks near the pump room. circulated via the automatic tank washing system pump and heater to the tank to the cleaned, wherefrom the solution is returned to the chemical solution tank via the stripping line. Usually it is not possible to recirculate solution through the tank washing system heater (to maintain solution temperature) without making a temporary connection between the chemical solution tank and the tank washing pump. Capacities of solution tank, pipelines and pumps etc. should be calculated carefully to ensure sufficent volumetric quantity for a continuous recirculation. Depending on size and condition of tanks to be cleaned and quantity of chemical solution a drawback in this method is that usually only 3 (three) tanks can be cleaned with one solution after which a fresh solution should be made and heated before cleaning can continue. The required solution strength is 2 - 6 % Careclean Voyage. After chemical cleaning the tanks should be rinsed thoroughly with sea water of fresh water depending on availability and requirements. Voyage Cleaning Method: (Double Bottom Tanks) Time, temperature and agitation of chemical solution are important factors for the successful cleaning of Double Bottom. Tank 1. Heat tank to higher than normal temperature, pump out as much fuel as possible and trim

vessel to ensure complete stripping. 2. Close all valves on engine room manifold. 3. Introduce first dose of Careclean voyage, through the sounding pipe, in accordance with the

dosage table stated below and fill the tank to 25% of its capacity with sea water. For filling the tanks it is adviced not to use the ballast lines as they may contain fuel oil making the cleaning more difficult.

4. Heat cleaning solution to minimum 60°C and maintain temperature for 48 hours. If heating coils are not available, live steam may be used for heating the solution and maintain temperature.

5. Empty tanks completely, fill to 50% capacity and empty again. Where single stage cleaning is used the previous steps are ignored.

6. Add second dose of Careclean voyage and fill tank with sea water to 50% of its capacity, continue heating and maintain at this level for 48 hours.

7. Add further sea water to fill tank to 75% capacity, continue heating and maintain for another 48 hours.

8. Empty tanks and pressure rinse with clean water through sounding pipes for 1-1 hour under continuous stripping. Pressure should be kept as high as safety permits.

9. When rinsing is completed stop discharge (stripping) pump and fill tank until clear water runs from sounding pipes on deck.

10. Stop water supply and empty (strip) tank. Trim vessel to ensure complete stripping. Note: If tanks are not serverely contamined and/or the fuel oil viscosity is lower than 180 cSt at

50°C th cleaning process should be in one stage using step 5-10 only.

Properties Highly concentrated blend of aromatic solvents emulsifiers and surface active ingredients. Light yellow coloured neutral liquid. Emulsifiable with water to a maximum of 50%. Undiluted at room temperature or in emulsions with water up to 6% at a maximum temperature of 60°C it can also be used on plastic materials, epoxy and zinc silicate coatings.

CARECLEAN PICKLING LIQUID Liquid for pickling austenitic stainless steel

Careclean Pickling Liquid is based on nitric acid, hydrofluoric acid and non-ionic surface-active substances. The fluid may be used only on austenitic stainless steel as it corrodes other materials. It removes weld slag, annealing scale, grinding dust and iron parts etc.

Applications Careclean Pickling Liquid is used mainly for pickling installations and tanks. It may be used in the following ways: 1. By circulation 2. Spraying 3. In immersion baths Directions for use Pretreatment Before commencing clean and degrease the surfaces to be pickled, this will give the basis for uniform pickling. Use Careclean ECS Quick Dry to remove felt pen ink marks. Use Careclean Alkaline for degreasing small metal surfaces. To degrease tanks etc. We advice the use of a 1-5% solution of Careclean Aquawash in warm water. After pickling rinse thoroughly with a jet of water. Circulation method This method is used mainly for pipe systems. Fill the system with cold undiluted Careclean Pickling Liquid. Pickling will take 2 to 6 hours depending on the degree of soiling and on the kind of austenitic steel do not pickle longer than necessary. Drain the system and rinse carefully, preferably with demineralised water. After rinsing if required passivation should follow immediately. For this use Careclean Passivating Liquid. Note: Before disposing the pickling liquid it should be neutralised with slaked lime.

Immersion bath method Fill a plastic or plastic lined bath with undiluted Pickling Liquid. Place the articles to be pickled into the bath and leave them to soak for 1 to 6 hours depending on the degree of soiling and the kind of austenitic steel. Remove the articles from the bath and spray them with a powerful water jet. Demineralised water should preferably be used for this purpose. Passivation should follow immediately after spraying. Passivation A protective oxide layer will form on the austenitic stainless steel only if oxidizing conditions are present. For example during longterm rinsing in oxygen rich water of during storage in the open air. In these circumstances the steel automatically passivates. Because this passive layer takes a long time to develop to the correct thickness we recommend passivating with Careclean Passivating Liquid, particularly if the stainless steel is exposed to corrosive conditions soon after the pickling treatment. Good results are obtained if the object is sprayed/brushed with Careclean Passivating Liquid immediately after it has been rinsed. Rinse with plenty of water after approx. 5 minutes. Treatment of the effluent To neutralise the acid and to make the fluorides and heavy metals insoluble the effluent water and paste should treated with slaked lime to give a pH balance of 8,5-9. After the soluble substances have settled the uncontaminated water may be drained. Isolate the insoluble contamination and if possible drain by means of filtration, otherwise mix with sawdust and dispose of as chemical waste.

Properties Strong acidic product containing nitric acid and hydrofluoric acid. Fully miscible with water. Suitable only for use on austenitic stainless steel. Corrosive on all other steels and many other materials. Specific gravity (at 20%) : 1,1 Flashpoint c.c. : none pH (1% solution) : approx. 2

CARECLEAN PICKLING PASTE

Pickling Paste for austenitic stainless steel.

INTRODUCTION

Careclean Pickling Paste is a colourless paste for austenitic stainless steel. It contains nitric acid and hydrofluoric acid. It contains neither hydrochloric acid nor chlorides. APPLICATION Careclean Pickling Paste is used for the pickling of welded seams and surfaces of austenitic stainless steel in any kind of construction, included for instance the outside of pipes and tanks. Steels other than austenitic stainless steel will be corroded by the strong pickling effect of the Careclean Pickling Paste. Nickel, nickel- and copper-nickel-alloys may also be pickled with the Careclean Pickling Paste. Special precautions have to be followed to prevent these materials from corrosive attack. Some of these metals and welding materials have been tested. Kindly contact Marine Care for further information. DIRECTIONS FOR USE 1. Pretreatment

See general information.

2. Pickling Please read the security instructions before you start pickling. During storage the paste may become partially liquid. Mix the Careclean Pickling Paste, using a plastic or wooden spoon, then put it on the surfaces and welded seams to be treated. Use a resistant brush without metal parts. If the pickling treatment is protracted, clean the brush frequently, so that the dirt is not

widely spread. On conclusion, clean the brush thoroughly with water and allow it to dry. The Careclean Pickling Paste is applied at room temperature, until the surface is well

covered; a thicker coating should be applied to the welded seams. 1 Kg. of the paste is sufficient to treat about 70-150 m. of welded seams (5cm wide) or 4-8m² surface

depending on the quantity and nature of iron oxides to be dissolved. Allow the pickling agent to act for 15-60 minutes on austenitic stainless steel, 5-20

minutes on nickel, nickel-alloys and copper-nickel-alloys (see Applications). If the pickling has not been sufficient, then rinse and reapply the paste. For a temperature change of 10 degrees centrigade up or down from room temperature, the pickling activity and thus the pickling time changes roughly by a

factor of two. Normally it is sufficient to let the Careclean Pickling Paste act for the given time without a further mechanical action. As the welding quality has a big influence, further mechanical aid may become necessary. This may for instance be done by brushing with brushes made from natural or plastic fibres or from austenitic stainless steel, provided that the paste is still active.

3. Rinsing off the Careclean Pickling Paste

The Pickling Paste must be removed completely by an efficient rinsing process. The main past of the paste may also be removed with rags or tissues.

Dirt that may not be chemically dissolved will be partially or completely loosened by the acid creeping in between the metal and the contaminant. Therefore we recommend rinsing with a cold high pressure water jet of at least 50-60 bar, to remove the dirt and the paste. If higher pressure water jetting is not possible, then you can improve the rinsing by brushing with e.g. natural or austenitic stainless steel brushes or with appropriate grinding pads. Nickel, its alloys and copper-nickel alloys have to be rinsed and cleaned very thoroughly after pickling. The chloride content of the rinsing water should be as low as possible. If possible, use demineralised water. 4. Passivation

See general information. 5. Treatment of the effluent

See general information.

PROPERTIES Strongly acid product. Product contains nitric acid and hydrofluoric acid, contains neither hydrochloric acid nor chlorides. Completely miscible with water. To be used for the pickling of austenitic stainless steel, too corrosive on other steels. To be used on nickel, nickel alloys and copper-nickel-alloys under special precautions - please contact Marine Care. Specific gravity (at 20°C) : 1,28 Flashpoint c.c. : none pH (1% solution) : 1,1

INTRODUCTION The cleaning of heavily contaminated fuel and lubricating oil filters, cylinderheads and aircoolers often give problems. The use of a cleaning agent only is generally unsatisfactory as only a part of the deposits will be removed, and in most cases carbon residues and other solid materials will be left behind. In such cases the use of ultrasonic sound waves in combination with a special cleaning agent gives good results. The contamination will be removed by the ultrasonic process in the liquid. The special detergents in the cleaning agent keep the contamination dispersed in the liquid and the complexing agents will partly dissolve them. Careclean Ultrasonic has been developed for use in ultrasonic baths for the cleaning of all materials except zinc, galvanised parts and/or magnesium alloy.

APPLICATION

Careclean Ultrasonic is used in ultrasonic cleaning baths and in cleaning machines.

DIRECTIONS FOR USE

In Ultrasonic Cleaning Baths The components to be cleaned can, if necessary, be degreased with Careclean Quick Split and Careclean ECS Quick Dry. Depending on the degree of contamination, Careclean Ultrasonic should be used in a 5 - 25% solution in water at a temperature of 50 - 70° C. Dismantle the equipment to be cleaned (i.e. : remove top and bottom rings from filtercandles), put the components in the bath taking care that the elements are completely immersed and kept separate.

We recommend a cleaning time of 5 - 30 minutes but longer if necessary. Take the elements out of the bath and spray with a powerful waterjet. After drying, an Anti Moisture Spray can be used to preserve the elements. The cleaning solution has to be renewed and the bath cleaned regularly, because in a contaminated bath the parts cannot be cleaned effectively. Marine Care design build and commission the "Caretech" ultrasonic cleaning bath systems.

Cleaning Machines

Careclean Ultrasonic is, depending on the nature and degree of contamination, applied in approx. 4% solution in cleaning machines. The contaminated objects must be placed in the machine and cleaned for 30-60 min. at a temperature of 80 - 90° C. Finally rinse with water. PROPERTIES Careclean Ultrasonic is a low foaming mild alkaline liquid. It can be used on all common metals except zinc, galvanised materials and some magnesium alloys. We advise to test lightmetal alloys (aluminium/magnesium alloys etc.) i.e. pistons, turboblower parts etc. in advance for 5-10 minutes. Suitable for use on synthetic materials, rubber and cured lacquers. Colour : yellowish Specific gravity (20°C) : 1.19 Flash point PM CC : none pH (1% solution) : approx. 11,5 For detailed information on safety and health, please refer to Material Safety Data Sheet and / or

CARETREAT BACTERIA

A microbiological control agent for use in water, lube oil and fuel oil systems

* Effective against bacteria and algae in oil and contaminated water. * Special surface active component ensures complete coverage over large areas. * Simple control and monitoring program. * Easy to use liquid. Application Caretreat Bacteria is used in cooling water systems and oil storage facilities which have problems due to bacteria colonization and/or algae in the oil/water interface. Caretreat Bacteria is ideally suited to the sterilization of Marine Diesel Engine Cooling Water Systems which have bacteria and/or algae infection. Diesel Cooling Systems have been prone to this, due to the common occurrence of lubricating and/or fuel oil mixing with cooling water. This gives an oil/water phase ideal for bacteria to colonize rapidly. Water containing bacteria leaks into the lube oil system due to faulty glands, joints and seals or during routine maintenance. Small amounts of infested water/oil sludges in the storage and circulatory parts of the lube oil system can quickly lead to major failure of bearing surfaces due to acidic conditions and degradation of the oils lubricating properties. Directions for use Sterilization of the water system:

The system should be drained and refilled with fresh water treated with Caretreat Bacteria at 500-700 ml to each m3 of water. Let the Caretreat Bacteria react for 48 hours under circulation with the separate cooling water pump or with the unloaded engine. During this operation, careful attention should be maid to blanked pipes and bypass loops, etc. to ensure that they also receive adequate treatment. After 48 hours, drain the system as quickly as possible through all outlets. Refill the system with distilled water and add Caretreat 2 Diesel to give the correct corrosion inhibition levels and add 500 ml Caretreat Bacteria to each m3. The product is not to be used in potable water systems without special instructions from Marine Care.

Refill the system with distilled water and add Caretreat 2 Diesel to give the correct corrosion inhibition levels and add 500 ml Caretreat Bacteria to each m3. The product is not to be used in potable water systems without special instructions from Marine Care Sterilization of lube oil systems: After serious contamination, all areas possible should be cleaned manually to remove sludge and slime. On large engines, cleaning with undiluted Careclean Heavy Duty Split of the casing frame followed by opening and thoroughly cleaning the sumps is strongly recommended. This should be followed by flushing of the entire lubricating oil system with a flushing oil containing 500 - 700 ml of Caretreat Bacteria for every m3.

Sterilization of fuel storage tanks: The action of bacteria in fuel during storage is widely misunderstood and its results often thought to be that of stratification of blended fuels due to incompatibility. If bacteria is suspected, water drawn from the fuel storage tank bottoms should be tested with the Marine Care "Dip Slide Test" and the bacteria count established. If it is above 105/ml, there is a good chance that colonization has taken place throughout the fuel. In that case, treat at 700 - 1000 ml of Caretreat Bacteria to each m3 of fuel. NOTE: These basic instructions are intended to give a reasonable guide to the actions required. * Please contact Marine Care for more details and specific recommendations.

Properties A light greenish liquid. Specific gravity : 1.01 Flash point : None pH (conc.) : approx. 3 IMO-Code : None.

NATURE OF SPECIAL RISKS AND SAFETY ADVICE In accordance with the latest E.E.C. Council directives this product is not subject to any official recommendation. Voluntary Marine Care recommendation: Harmful by inhalation and if swallowed. In case of contact with skin/eyes, wash immediately with plenty of water. Wear suitable gloves and eye/face protection.

CAREFLOC

A general purpose dispersant for effective removal of mud and silt from ballast tanks,

pipe line systems, open and closed cooling water circuits. * Non hazardous, chemically inert product * Prevents mud and silt from settling in tank * Removes already settled mud and silt sediments * Low dosage rates * Biodegradability above 99%.

Directions for use Cleaning dirty ballast tanks Marine Care Carefloc must be dosed to the tank at the rate of 1 ltr. product to 10m3 water. If possible water volume in the tank should be minimised to reduce product requirement. Maximum agitation should be provided by back flushing when pumping out. Ballast tank treatment To maintain good conditions in a clean tank Carefloc must be added at 1 ltr. product to 20 m3

water. Both dosage recommendations should be considered as the minimum for full effectivenes. Carefloc should be added via the tank covers, avoiding dispersion problems when dosed via vents or sounding tubes. If the latter is unavoidable, ensure that plenty of water is added directly after, to aid mixing.

Open cooling water systems

Dirty systems should be cleaned by injecting Carefloc at the rate of 1 ltr. product to 10 m3circulating water flow over a one hour period every 24 hours. This rate can be reduced by 50% once a system is reasonably clean and requires maintenance of those conditions. Diesel engine cooling water systems

Desludging must be carried out by injecting a minimum dose of 1 ltr. Carefloc to 10m3 water capacity. Small systems of less than 2.5 m3 should use 0.3 ltr. of Carefloc regardless of capacity. Carefloc should be injected into the system at a high dosing point, but if the header tank is used, ensure that the make-up valve is closed and water level lowered below the cylinder levels before Carefloc is added to the tank. Add the calculated volume of Carefloc to the empty tank and then open the make-up valve to refill the system. This ensures that the product enters the cooling circuit.

Circulate for 30 – 40 minutes then completely drain the system as quickly as possible using all drains and removing covers if practical. Addition of untreated water whilst draining will assist in removing treated sludge. Repeat the operation if sludge level is excessive. Heat exchangers – sea water side

Static method

Isolate unit and add 1 ltr. Carefloc to 10 m3 water capacity. If possible, agitate with an air line or temporary circulation loop. After 30 minutes, flush thoroughly with water to remove all floculated deposits. Note: If “on load” cleaning of specific coolers is required, inject 1 ltr. Carefloc to 10 m3 cooler throughput upstream of the unit for 1 hour. General hints

A. Prolonged contact of Carefloc with sludge reduces its effective floculation. This should be considered in ballast tanks which are not continuously being discharged. Sludge should be removed within seven days maximum.

B. Above 60° C the effect of Carefloc is reduced and, if necessary, dosage rates must be increased.

C. Carefloc will function over the full pH range, however, it is more effective in alkaline conditions.

D. Do not use less than 1 ltr. of Carefloc to 20 m3 water. Injection Equipment

Marine Care has a range of pump and tank units suitable for the injection of Carefloc. Properties

Carefloc is a light yellow liquid. Specific gravity (20°C) : 1.3 pH : approx. 7 Flash point : none IMO-Class : non hazardous. Nature of special risks and safety advice.
