Reduction of Fuel Cost by 3%

• 3% fuel savings will generate operating cost savings of $600,000 to$1,200,000 per annum per tanker

• Annual fuel cost per ship ranges from$20,000,000 to $40,000,000 per annum

• Fleet size of (10) ships could achieve savings of $6,000,000 to $12,000,000 per annum

Quantifying Savings

• Fuel consumption per typical tanker 40,000to 50,000 MT per annum

• Average carbon content of marine fuels isabout 86%

• CO2 production per ship: 140,000 to 160,000MT per year

• 3% fuel saving = CO2 reduction of 4,500 MTper annum per ship

• 10 ship fleet equates 45,000 MT per annumof CO2 reduction

Reduced emissions due to less tank cleaning

• High Functionality Polymer coated vesselproduces 78.5% less CO2 emissions comparedto the zinc coated vessel for the same tankcleaning operation.

Zinc Coated Vessel

• 56 hours of hot water washing produces 106.4MT of CO2

High Functionality Polymer Coated Vessel

• 12 hours of hot water washing produces 22.8MT of CO2

Quantifying Savings

9

• A vessel “costs” $18,000 per day• A vessel has 16 cargo tanks.• 4 cargo tanks can be cleaned simultaneously.• Each cargo tank requires 200L of cleaning chemical(s) (where cleaning chemicals are required).• The typical cost of a regular cleaning chemical is $3 per litre

Zinc Coated Vessel High Functionality PolymerCoated Vessel

Total Cleaning Time 64 hours 16 hours

Hot Water Cleaning Time 56 hours 12 hours

Cleaning Chemical Consumption 3200L 0L

• The financial advantages of a High Functionality Polymer versus zinc silicate in this example can bequantified as follows:

Total time saving 48 hrs = $36,000Cleaning chemical saving 3200L = $9,600Hot water washing saving 44 hrs = 26.4MT of fuel**

(** On average a vessel consumes 0.6MT per hour of HFO / MGO in the boiler and A/E during tank cleaning).

• What makes a cargo tank clean, or not?

• The first point to consider is that the efficiency of all tank cleaning operations is determined by some kind of inspection

Visual

Wall Wash


• Visually clean is fairly self explanatory

✓ CDOF – Clean Dry Odour Free

• But “wall wash” standard is less straightforward because there is no universal specification

✓ How Clean is Clean?


• And who decides the wall wash specifications and what are they?

• Charterers and / or cargo Interests


Dear Guy

Good day sir,

I have one question about WWT criteria.We would like to carry cargo of naphtha which product of GS Caltex Yeosu.For this cargo, charterer informed WWT requirement as bellows;--------------------------------------------------------------------------------------------------------------OWNERS CONFIRM VESSEL/MASTER WILL COMPLY WITH BELOW WALL WAST TEST CRITERIA PRIOR LOADING- APPEARANCE-VISUAL-PASS-CLEAR AND FREE OF SUSPENDED WATER- HYDROCARBONS – 125 PPM MAX- CHLORIDE – 0.5 PPM MAX- WATER MISCIBILITY – SPEC/RESULT : COMPLETE- NONVOLATILE MATTER – SPEC MAX 5 PPM GC- PT - CO COLOR METHOD D5386 MX 15- NITROGEN 1 MAX ASTM D6069- PERMANGANATE TIME TEST – MIN 30 MIN @ 15 DC


Dear Julie,

Charterers have advised zero chlorides, I just asked them to reconfirm same and they replied;

That's correct. Zero.

What is the wall wash?L&I

• It is supposed to provide information to indicate whether a cargo tank is “clean” or not

• But what does it actually tell us?


• Really only that the bottom 2 – 3M of the cargo tank is clean. Approximately 1% of the internal surface area of the tank?

• What about the remaining 99%?

• It is an “unknown” ..


• And then we have to ask the most important question ..

• What are the wall wash specifications? How clean is clean?

• Blank canvas / no limitations for commercial interests


• To one charterer a colour of 10 is acceptable, to others it is “dirty”


• An inorganic chloride level higher than 0.5ppm is apparently evidence of “poor” tank cleaning.

• Really? 1 second in 23 days …


• If a vessel does not pass the wall wash, it cannot load the next cargo

• Even though it represents less than 1% of the internal surface area of the cargo tank and perhaps more importantly none of the cargo lines.


But if as much as 99% of the cargo tank is potentially un-clean at the start of cargo operations ..

Why do we not see more off-specification cargoes?


• DILUTION EFFECTS

• Or .. what happens to the contaminants found in the wall wash sample when the tank is fully loaded

• Typically 3000 times dilution


• Wall wash inspections are imposed for one reason:

• To provide reassurance to cargo interests that any particular cargo tank is suitable to load the next nominated cargo

• But this is just not possible.

• All they do is contribute to unnecessary CSE and overcleaning (GHG emissions)


• Each hour of hot water washing, consumes on average 0.6MT per hour of HFO / MGO in the boiler and A/E

• Burning 1MT of HFO produces approximately 3.2MT of CO2

• Meaning each hour of hot water washing liberates1.9MT of CO2 into the atmosphere


• The dilution effect “allows” us to load chemical cargoes without them becoming contaminated.

• Not the wall wash specification.

• Focus on main area of concern, using techniques such as UV spectroscopy


• Emerging trend for received cargoes to be tested for extremely low levels of previous cargo. WHY?

• Capability, bargaining tool and no faith in the wall wash.

• But what impact does this have on tank cleaning?

• And what about the influence of the cargo tank lining?


• Stainless steel. Organic Coating. Inorganic Coating.

• If the coating / lining absorbs previous cargo residues, this needs to be recognised and understood. WHY?

• The wall wash generally does not pick these residues up. Contact time.

• Do not pretend that a “good” wall wash result means the cargo tank is suitable


• Lab based project.

• Test panels immersed in different cargoes, cleaned until the wall wash passed, before being immersed in methanol.

• The methanol was tested for the presence of the previous cargo

L&I

• Coatings that actively absorb certain cargo types should not be loaded directly afterwards with cargoes that are sensitive to the previous cargo.

• Commercial interests need to understand this as well.

• If the next cargo is high purity, choose a coating with a good prior cargo history, or a premium coating or stainless steel.

• Do not hide behind the wall wash

• Do not gamble safety/sustainability against cargo quality
