Foreword

On '17

June 1983 the Marit ime Safety Committee (MSC) adopted, byresolut ion MSC.4(4S). the Internat ional Code for the Construct ion andEquipment of Ships Carry ing Dangerous Chemicals in Bulk ( lBC Code).Under the provisions of chapter Vll of the International Convention for theSafety of Life at Sea, 1974 (SOLAS 74), as amended in 1983, chemicaltankers constructed on or after 1 July 1986 must comply with the provisionsof the Code.

On 5 December 1985, by resolution MEPC.'|9(22), the IBC Code wasextended by the Marine Environment Protection Committee (MEPC) to covermar ine pol lu t ion aspects for the implementat ion of Annex l l o f theInternational Convention for the Prevention of Pollution from Ships,

' l 973,

as modified by the Protocol o{ 1978 relating thereto (MARPOL 73178).Under the provisions of regulation

.l 3 of Annex ll of MARPOL 73/78,chemical tankers constructed on or after 1 July 1986 must comply with theprovisions of the Code.

The MSC then formally adopted the same amendments as those adopted bythe MEPC by resolut ion MSC.10(54) , under ar t ic le Vl l l (b) of SOLAS 74, sothat the IBC Code remains identical for the purposes of both MARPOLT3ITBand SOLAS 74-

The two Committees subsequently established appropriate procedures foramending the IBC Code (MEPC.25120, annex Z) to ensure that the Coderemains identical at all t imes under the mandatory requirements of the twoConventions.

Under MARPOL 73/78 chemical tankers constructed before 1 July 1986must comply with the provisions of the Code for the Construction andEquipment of Ships Carry ing Dangerous Chemicals in Bulk (BCH Code).Under SOLAS 74 the BCH Code remains as a recommendation. The BCHCode is issued as a separate publication.

The /ndex of Dangerous Chemicals Carried in Bulk - a supplement to the IBCand BCH Codes, contained an index of all chemicals referred to in the BCHand IBC Codes which provided the various names known for a particularchemical. This index has now been updated and incorporated into thepresent publ icat ion. Previously , annexes l l and l l l o f MARPOL 73/78contained lists of products which were reproduced in chapters 1 7 and 18of the IBC Code as wel l as chapters Vl and Vl l o f pre-1993 edi t ions of theBCH Code. However, since 1993, the l ists of products in chapters Vl and Vllof the BCH Code have been replaced by references to the IBC Code. Inaddi t ion, the l is ts of products in appendices l l and l l l o f annex l l to the ' l 997consolidated edition of MARPOL 73/78 have also been replaced byreferences to the IBC Code. As a result, the IBC Code is now the definit ive

i l l

IBC Code

source of names for products subject to appendices l l and l l l of Annex ll of

MARPOL 73178.

Reference is also made to the MEPC.2f Circs, issued annually in December;these contain , inter alia, details of products that have been the subject ofTripartite Agreements and are, in effect, a supplement to the IBC Code.Annex 1 of these circulars includes products that are expected to becomenew or amended entries to the IBC Code. A future amendment, shown in the

circular, serves as prior notice of the carriage conditions which wil l only apply

to that product when the next set of amendments enter into force.

A number of other documents closely related to the IBC Code are annexed to

this publication.

The MSC and MEPC agreed that, at their spring 1990 sessions, they would

adopt amendments to the BCH Code to introduce the harmonized system of

survey and certif ication. Under the provisions of these proposed amend-

ments, they wil l enter into force when the 1988 SOLAS Protocol, which

contains corresponding provisions, enters into force, at which time section.l .5 and the model form of the Certif icate of Fitness wil l be replaced.

IBC Code

Preamble

I The purpose of this code is to provide an international standard forthe safe carriage by sea in bulk of dangerous and noxious l iquid chemicalslisted in chapter 1 7 of the Code by prescribing the design and constructionstandards of ships, regardless of tonnage, involved in such carriage and theequipment they should carry so as to minimize the risk to the ship, to its crewand to the environment, having regard to the nature of the products involved.

2 The basic philosophy is to assign to each chemicar tanker one of theship types according to the degree of the hazards of the products carried bysuch ship. Each of the products may have one or more hazard properties,which include flammability, toxicity, corrosivity and reactivity, as well as thehazard they may present to the environment if accidentallv released.

3 Throughout the development of the Code it was recognized that itmust be based upon sound naval architectural and engineering principlesand the best understanding available as to the hazards of the variousproducts covered; furthermore that chemical tanker design technology is notonly a complex technology but is rapidly evolving and that the code shouldnot remain static. Therefore the organization wil l periodically review theCode, taking into account both experience and technical development.

4 Amendments to the Code involving requirements for new productsand their conditions of carriage wil l be circulated as recommendations, on aninterim basis, when adopted by the Marit ime safety committee (MSC) andthe Marine Environment Protection Committee (MEpc) of the organization,in accordance with the provisions of article vll l of the InternationalConvention for the Safety of Life at Sea, 1924 (SOLAS 74\, and article 16of the International Convention for the prevention of pollution from ships,1973, as modified by the Protocol relating thereto (MARPOL 73/78),respectively, pending the entry into force of these amendments.

5 The code primarily deals with ship design and equipment. In order toensure the safe transport of the products, the total system must, however, beappraised. other important facets of the safe transport of the products, suchas training, operation, traffic control and handling in port, are being or wil l beexamined further by the Organization.

6 The development of the Code has been greatly assisted by rerevantwork of the International Association of classification Societies (IACS) and ofthe International Electrotechnical Commission (lEC).

7 Chapter 16 of the Code, dealing with operational requirements ofchemical tankers, highlights the regulations in other chapters that areoperational in nature and mentions those other important safety features thatare peculiar to chemical tanker operation.

IBC Code

I The layout of the Code is in l ine with the lntemational Code for the

Construct ion and Equipment of sh ips carry ing L iquef ied cases in Bulk ( lcC

Code), adopted by the Marit ime Safety Committee at its forty-eighth session.

Cas carriers may also carry in bulk l iquid chemicals covered by this Code, as

prescribed in the IGC Code.

g The 1998 edition of the Code is based on the original text as adopted

bv MSC resolut ion MSC.4(48) . In response to resolut ion 15 of the

lnternational Conference on Marine Pollution, 1973, the MEPC, at its

twenty-second session, adopted, by resolution MEPC.1 9(22), rhe IBC Code

extended to cover marine pollution prevention aspects for the implementa-

t ion of Annex l l to MARPOL 73/78.

t0 Subsequent to th is , the 1998 edi t ion of the Code inc ludes

amendments adopted by the following resolutions:

l l As from the date of entry into force of the 1983 amendments to

SOLAS 7a ( i .e .1 July 1986) and the date of implementat ion of Annex l l o f

MARPOL 73178, this code became subject to mandatory requirements

under these Conventions. Amendments to the Code, whether from the point

of view of safety or of marine pollution, must therefore be adopted and

brought into force in accordance with the procedures laid down in article Vll l

of SOLAS 74 and article 16 of MARPOL 73178 respectively.

.l products having significant f ire hazards in excess of those ofpetroleum products and similar f lammable products;

.2 products having significant hazards in addition to or other thanflammability.

Products that have been reviewed and determined not to present safety andpollution hazards to such an extent as to warrant the application of the Codeare found in chapter 18.

1.1.2 Liquids covered by the Code are those having a vapour pressure notexceeding 2.8 bar absolute at a temperature of 37.8"C.

f .f .2A For the purpose of the 1974 SOLAS Convention, the Code does notapply to ships which are engaged in the carriage of products included inchapter 17 solely on the basis of their pollution characteristics and identif iedas such by an entry of "P" only in column d,

f.f.2B For the purposes of MARPOL 73/78, the Code applies only tochemical tankers, as defined in regulation 1(1 ) of Annex ll thereof, which areengaged in the carriage of noxious l iquid substances fall ing into category A, Bor C and identif ied as such by an entry of "A", "8" or "C" in column c.

1.1.3 For a product proposed for carriage in bulk, but not l isted in chapter17 or 18, the Administration and port Administrations involved in suchcarriage should prescribe the preliminary suitable conditions for the carriage,having regard to the criteria for hazard evaluation of bulk chemicals. TheOrganization should be notif ied of the conditions for consideration forinclusion of the product in the Code. For the evaluation of the pollutionhazard of such a product and assignment of its pollution category, theprocedure speci f ied in regulat ion 3(4) of Annex l l o f MARPOL73l78 must befollowed.

1.1.4 Unless expressly provided otherwise, the Code applies to ships thekeels of which are laid or which are at a stage at which:

.l construction identif iable with the ship begins; and

the estimated mass of all structural material, whichever is less;

on or after 1 July 1986.

1.1.5 A ship, irrespective of the date of construction, which is converted toa chemical tanker on or after 1 July 1986 should be treated as a chemical ;tanker constructed on the date on which such conversion commences. This ,conversion provision does not apply to the modification of a ship referred toin regulat ion 1(12) o l Annex l l o f MARPOL 73178.

1.1.6 Where reference is made in the Code to a paragraph, all the ,provisions of the subparagraphs of that designation should apply.

1.5 Surveys and certification

f .5.1 Survey procedure

1.5.1.1 The survey of ships, so far as regards the enforcement of theprovisions of the regulations and granting of exemptions therefrom, shouldbe carried out by officers of the Administration. The Administration may,however, entrust the surveys either to surveyors nominated for the purposeor to organizations recognized by it.

1.5.1.2 The Administration nominating surveyors or recognizing organiza-t ions to conduct surveys should, as a min imum, empower any nominatedsurveyor or recognized organization to:

.l require repairs to a ship; and

.2 carry out surveys if requested by the port State authority'concerned.

Chapter 2Ship survival capability* and

Iocation of cargo tanks

2.1 General

2'l ' l ships subject to the Code should survive the normal effects of f lood-ing following assumed hull damage caused by some external force. In addi-tion, to safeguard the ship and the environment, the cargo tanks of certaintypeqof ships should be protected from penetration in the case of minordamage to the ship resulting, for example, from contact with a ietty or tug,and given a measure of protection from damage in the case of coll isron orstranding, by locating them at specified minimum distances inboard from theship's shell plating. Both the damage to be assumed and the proximity of thecargo tanks to the ship's shell should be dependent upon the degree ofhazard presented by the products to be carried.

2.1.2 Ships subject to the Code should be designed to one of the followingstandards:

.1 A type 1 ship is a chemical tanker intended to transport chaprer17 products with very severe environmental and safety hazardswhich requi re maximum prevent ive measures to prec luoe anescape of such cargo.

.2 A type 2 ship is a chemical tanker intended to transport chapter17 products with appreciably severe environmental and safetyhazards which require significant preventive measures to pre-clude an escape of such cargo.

.3 A type 3 ship is a chemical tanker intended to transport chapter17 products with sufficiently severe environmental and safetyhazards which require a moderate degree of containment toincrease survival capabil ity in a damaged condition.

Thus a type 1 ship is a chemical tanker intended for the transportation ofproducts considered to present the greatest overall hazard and type 2 andtype 3 for products of progressively lesser hazards. Accordingly, a type 1 shipshould survive the most severe standard of damage and its cargo tanks shouldbe located at the maximum prescribed distance inboard from the shellplating.

* Reference is made to the Cuidelines for the uniform application of the survival requirements

of the Bulk Chemical Code and the Cas Carrier Code (see page 201).

1 3

IBC Code

2.1.3 The ship type required for individual products is indicated in column e

in the table of chapter 17.

2.1.4 lf a ship is intended to carry more than one product l isted in chapter

17, the standard of damage should correspond to that product having the

most stringent ship type requirement. The requirements for the location of

individual cargo tanks, however, are those for ship types related to the

respective products intended to be carried.

2.2 Freeboard and intact stability

2.2.1 Ships subject to the Code may be assigned the minimum freeboardpermitted by the International Convention on Load Lines in force. However,

the draught aqociated with the assignment should not be Sreater than the

maximum draught otherwise permitted by this Code.

2.2.2 The stabil ity of the ship in all seagoing conditions should be to a

standard which is acceptable to the Administration.

2.2.1 When calculaiing th" effect of free surfaces of consumable l iquids for

loading conditions it should be assumed that, for each type of l iquid, at least

one transverse pair or a single centre tank has a free surface and the tank or

combinat ion of tanks to be taken into account should be those where the

effect of free surfaces is the greatest. The free surface effect in undamaged

compartments should be calculated by a method acceptable to the

Administration.

2.2.4 Solid ballast should not normallv be used in double-bottom spaces in

the cargo area. Where, however, because o{ stabil ity considerations, the fit-

t ing of solid ballast in such spaces becomes unavoidable, then its disposition

should be governed by the need to ensure that the impact loads resultingfrom bottom damage are not directly transmitted to the cargo-tank structure.

2.2.5 The master of the ship should be supplied with a loading and stabil ity

information booklet. This booklet should contain details of typical service and

ballast conditions, provisions for evaluating other conditions of loading and a

summary of the ship's survival capabil it ies. In addition, the booklet should

contain sufficient information to enable the master to load and operate the

ship in a safe and seaworthy manner.

2.3 Shipside discharges below the freeboard deck

2.3.1 The provision and control of valves fitted to discharges led throughthe shell from spaces below the freeboard deck or from within the super-structures and deck-houses on the freeboard deck fitted with weathertight

doors should comply with the requirements of the relevant regulation of the

1 4

Chapter 2 - Ship survival capability and location of cargo tanks

lnternational convention on Load Lines in force, except that the choice ofvalves should be l imited to:

.l one automatic nonreturn valve with a positive means of closinefrom above the freeboard deck; or

.2 where the vertical distance from the summer load waterline to theinboard end of the discharge pipe exceeds 0.01[, two automaticnonreturn valves without positive means of closing, provided thatthe inboard valve is always accessible for examination under ser_vice conditions.

2.3.2 For the purpose of this chapter, ,,summer load line,, and ,,freeboarddeck" have the meanings as defined in the International Convention on LoadLines in force.

2.3.3 The automatic nonreturn valves referred to in 2.3.1 .1 and 2.3.1 .2should be fully effective in preventing admission of water into the ship, takinginto account the sinkage, trim and heel in survival requirements in 2.9, andshould comply wi$ recognized standards.

2.4 Conditions of loading

Damage survival capabil ity should be investigated on the basis of roadinginformation submitted to the Administration for all anticipated conditions ofloading and variations in draught and trim. Ballast conditions where thechemical tanker is not carrying products covered by the Code, or is carryingonly residues of such products, need not be considered.

2.5 Damage assumptions

2.5.1 The assumed maximum extent of damage should be:

. l S ide damage:

.l. l Longitudinal extent:

,1,2 Transverse extent:(measured inboardfrom the ship 's s ideat right angles to thecentreline at thelevel of the summerload l ine)

.1.3 Vertical extent:( f rom the moulded l ineof the bottom shellplating at centreline)

.2.3 Vertical extent: B/15 or 6 m,whichever is less

Imeasured fromthe moulded l ineof the bottomshel l p lat ingat centre l ine($ee 2.6.2))

2.5.2 lf any damage of a lesser extent than the maximum damage specifiedin 2.5.1 would result in a more severe condition, such damage should beconsidered.

2.6 Location of cargo tanks

2.6.1 Cargo tanks should be located at the iollowing distances inboard: \

.1 Type 1 ships: from the side shell plating, not less than the trans-verse extent of damage specified in 2.5.1 .1 .2, and from themoulded l ine of the bot tom shel l p lat ing at centre l ine, not lessthan the vertical extent of damage specified in 2.5.1 .2.3, andnowhere less than 76O mm from the shell plating. This require-ment does not apply to the tanks for diluted slops arising fromtank washing.

.2 Type 2 ships: from the moulded line of the bottom shell plating atcentreline, not less than the vertical extent of damage specified in2.5.1 .2.3, and nowhere less than 760 mm from the shel l p lat ing.This requirement does not apply to the tanks for diluted slopsarising from tank washing.

.3 Type 3 ships: no requirement.

2.6.2 Except for type 1 ships, suction wells installed in cargo tanks mayprotrude into the vertical extent of bottom damage specified in 2.5.1 .2.3provided that such wells are as small as practicable and the protrusion belowthe inner bottom plating does not exceed 25"/. of the depth of the doublebottom or 350 mm, whichever is less. Where there is no double bottom, theprotrusion of the suction well of independent tanks below the upper l imit ofbottom damage should not exceed 350 mm. Suction wells installed inaccordance with this paragraph may be ignored in determining the com-partments affected by damage.

Chapter 2 - Ship survival and location of cargo tanks

2.1 Flooding assumptions . ,:2.1.1 The requirements of 2.9 should be confirmed by calculations whichtake into consideration the design characteristics of the ship; the arrangements, configuration and contents of the damaged compartments; thedistribution, relative densities and the free surface effects of i iquids; and thedraught and trim for all conditions of loading.

2.1'2 The permeabil it ies of spaces assumed to be damaged should be asfollows:

2'1.3 wherever damage penetrates a tank containing riquids it shourd beassumed that the contents are completely lost from that compartment andreplaced by salt water up to the lever of the finar plane of "qriribriur.

2Jl Every watertight division within the maximum extent of damagedefined in 2.5.1 and considered to have sustained damage in positions givenin 2.8'1 should be assumed to be penetrated. where dimage ress than themaximum is being considered in accordance with 2.5.2, onry watertightdivisions or combinations of watertight divisions within the "nu"iopu of suchlesser damage should be assumed to be penetrated.

2'7'5 The ship should be so designed as to keep unsymmetrical f looding tothe minimum consistent with efficient arrangements.

2'1.6 Equalization arrangements requiring mechanical aids such as valvesor crossJevell ing pipes, if f ined, should not be considered for the purpose ofreducing an angle of heel or attaining the minimum range of residual stabil ityto meet the requirements of 2.9 and sufficient residual stabirity shourd bemaintained during all stages where equalization is used. spaces whicn arelinked by ducts of large cross-sectional area may be considered to becommon.

2'7'7 lf pipes, ducts, trunks or tunnels are situated within the assumedextent of damage penetration, as defined in 2.5, arrangements should besuch that progressive flooding cannot thereby extend to c-ompartments otherthan those assumed to be flooded for each case of damage.

:--- The permeabiliry of partially filled compartments should be consistent with the amount ofIquto carneo In tne compartment.

1 7

IBC Code

2.1.8 The buoyancy of any superstructure directly above the side damageshould be disregarded. The unflooded parts of superstructures beyond theextent of damage, however, may be taken into consideration provided that:

.1 they are separated from the damaged space by watertightdivisions and the requirements o( 2.9.3 in respect of these intactspaces are complied with; and

.2 openings in such divisions are capable of being closed byremotely operated sliding watertight doors and unprotectedopenings are not immersed wi th in the min imum range of res idualstabil ity required in 2.9; however, the immersion of any otheropenings capable of being closed weathertight may be permitted'

2.8 Standard of damage

2.8.1 Ships should be capable of surviving the damage indicated in 2.5 with

the f looding assumpt ions in 2.7 to the extent determined by the ship 's typeaccording to the fo l lowing standards:

.l A type 1 ship should be assumed to sustain damage anywhere in

i ts length;

.2 A type 2 ship of more than ' l

50 m in length should be assumed tosustain damage anywhere in its length;

.3 A type 2 ship of ' l 50 m in length or less should be assumed tosustain damage anywhere in its length except involving either of

the bulkheads bounding a machinery space located aft;

.4 A type 3 ship of more than 225 m in length should be assumed tosustain damage anywhere in its length;

.5 A type 3 ship of 125 m in length or more but not exceeding225 min length should be assumed to sustain damage anywhere in itslength except involving either of the bulkheads bounding amachinery space located aft;

.6 A type 3 ship below 125 m in length should be assumed to sustaindamage anywhere in its length except involving damage to themachinery space when located aft. However, the abil ity to survivethe flooding of the machinery space should be considered by theAdminis t rat ion.

2.8.2 ln the case of small type 2 and type 3 ships which do not comply in all

respects wi th the appropr iate requi rements o l 2.8.1.3 and 2.8-1 .6, specia l

dispensation may only be considered by the Administration provided that

alternative measures can be taken which maintain the same degree of safety.The nature of the alternative measures should be approved and clearly statedand be available to the port Administration. Any such dispensation should be

duly noted on the International Certif icate of Fitness referred to in 1.5.4.

4.1 Definitions

4.1.1 Independenttank means a cargGcontainment envelope which is notcontiguous with, or part of, the hull structure. An independent tank is builtand installed so as to eliminate whenever possible (or in any event tominimize) its stressing as a result of stressing or motion of the adjacent hullstructure. An independent tank is not essential to the structural completenessof the ship 's hul l .

4.1.2 lntegral tank means a cargo-containment envelope which forms partof the ship 's hul l and which may be st ressed in the same manner and by thesame loads which stress the contiguous hull structure and which is normallyessential to the structural completeness of the ship's hull.

4.f .3 Cravity tank means a tank having a design pressure not greater thanO.7 bar gauge at the top of the tank. A gravity tank may be independent orintegral. A gravity tank should be constructed and tested according torecognized standards, taking account of the temperature of carriage andrelative density of the cargo.

4.1.4 Pressure tank means a tank having a design pressure greater than0.7 bar gauge. A pressure tank should be an independent tank and shouldbe of a configuration permitting the application of pressure-vessel designcriteria according to recognized standards.

arrangements

8.1 Application

8.1.1 This chapter applies to ships constructed on or after ' l lanuary 1994.

8.1.2 Ships constructed before 1 January 1994 should comply with therequirements of chapter 8 of this Code which were in force prior to the saiddate.

8.1.3 For the purpose of this regulation, the term "ship constructed" is asdefined in regulation l l-1 11.3.1 of the ' l 974 SOLAS Convention as amended.

8.1.4 Ships constructed on orafter 1 July 1986 butbefore 1)anuary'1994which fully comply with the requirements of the Code applicable at that t imemay be regarded as complying with the requirements of regulation l l2/59 ofsoLAS 74.

8.1.5 For ships to which the Code applies, the requirements of this chaptershould apply in l ieu of regulat ion l l -2159.1 and 59.2 of the 1974 SOLASConvention, as amended.

8.2 Cargo-tank venting

8.2.1 All cargo tanks should be provided with a venting system appropriateto the cargo being carried and these systems should be independent of theair pipes and venting systems of all other compartments of the ship. Tankventing systems should be designed so as to minimize the possibil i ty of cargovapour accumulating about the decks, entering accommodation, service andmachinery spaces and control stations and, in the case of f lammable vapours,entering or collecting in spaces or areas containing sources of ignition. Tankventing systems should be arranged to prevent entrance of water into thecargo tanks and, at the same time, vent outlets should direct the vapourdischarge upwards in the form of unimpeded jets.

8.2.2 The venting systems should be connected to the top of each cargotank and as far as practicable the cargo vent l ines should be self-draining backto the cargo tanks under all normal operational conditions of l ist and trim.Where it is necessary to drain venting systems above the level of anypressure/vacuum valve, capped or plugged drain cocks should be provided.

8.2.3 Provision should be made to ensure that the l iquid head in any tankdoes not exceed the design head of the tank. Suitable highJevel alarms,overflow control systems or spil l valves, together with gauging and tank fi l l ing

3 6

ank venting and gas-freeing arrangements

procedures, may be accepted for this purpose. where the means of l imitingcargo-tank overpressure includes an automatic closing valve. the valveshould comply with the appropriate provisions of 15..1 9.

8'2'4 Tank venting systems shourd be designed and operated so as toensure that neither pressure nor vacuum created in the cargo tanks duringloading or unloading exceeds tank design parameters. The main factors to beconsidered in the sizing of a tank venting system are as follows:

.l design loading and unloading rate;

'2 gas evolution during roading: this shourd be taken account of bymultiplying the maximum loading rate by a factor of at least .|.25;

.3 density of the cargo vapour mixture;

.4 pressure loss in vent piping and across valves and fitt ings;

.5 pressure/vacuum settings of relief devices.

8'2.5 Tank vent piping connected to cargo tanks of corrosion_resistantmaterial, or to tanks which are rined or coated to handre speciar cargoes asrequired by the code, should be similarly l ined or coated or conJucted ofcorrosion-resistant material.

8.2.0 The master shourd be provided with the maximum permissibleloading and unloading rates for each tank or group of tanks coniistent withthe design of the venting sysrems.

8.3 Types of tank venting systems8'3.1 An open tank venting system is a system which offers no restrictionexcept for friction losses to the free flow of cargo vapours to and from thecargo tanks during normal operations. An open venting system may consist ofindividual vents from each tank, or such individual vJnts may u"'.o,.nuin"ainto a common header or headers, with due regard to cargo segregation. Inno case should shutoff valves be fitted either toihe individJal ue"nts"orto tneheader.

8'3'2 A controlled tank venting system is a system in which pressure- andvacuum-relief valves or pressure/vacuum valves are fitted to each tank tolimit the pressure or vacuum in the tank. A controiled venting ,yit", ' .,.,uyconsist of individual vents from each tank or such individual*vents on thepre.ssure side only as may be combined into a common header or headers,with due regard to cargo segregation. In no case shourd shut-off varves befitted either above or below pressure- or vacuum-rerief varves o,. pr"rrrr"7vacuum valves. Provision may be made for bypassing a pressure oi u".rr.-relief valve or pressure/vacuum varve undei certain operating conditionsprovided that the requirement of g.3.5 is maintained and ihat theie is suitableindication to show whether or not the valve is bypassed.

1.3'3 The position of vent outlets of a controlled tank venting system shouldbe arranged:

3 7

IBC Code

.l at a height of not less than 6 m above the weather deck or above araised walkway if f i tted within 4 m of the raised walkway;

.2 at a distance of at least 10 m measured horizontally from the near-est air intake or opening to accommodation, service and machin-ery spaces and ignition sources.

8.3.4 The vent outlet height referred to in 8.3.3.1 may be reduced to 3 mabove the deck or a raised walkway, as applicable, provided that high-velocity venting valves of an approved type, directing the vapour/air mixtureupwards in an unimpeded jet with an exit velocity of at least 30 m/s, arefitred.

8.3.5 Controlled tank venting systems fitted to tanks to be used for cargoeshaving a flashpoint not exceeding 60'C (closed-cup test) should be providedwith devices to prevent the passage of f lame into the cargo tanks. The design,testing and locating of the devices should comply with the requirements ofthe Administration, which should contain at least the standards adopted bythe Organization.-

8.3.6 In designing venting systems and in the selection of devices to preventthe passage of f lame for incorporation into the tank venting system, dueattention should be paid to the possibil i ty of the blockage of these systemsand fitt ings by, for example, the freezing of cargo vapour, polymer build-up,atmospheric dust or icing up in adverse weather conditions. ln this context itshould be noted that f lame arresters and flame screens are more susceotibleto blockage. Provisions should be made such that the system and fitt ings maybe inspected, operationally checked, cleaned or renewed as applicable.

8.3.7 Reference in 8.3.1 and 8.3.2 to the use of shutoff valves in the ventinglines should be interpreted to extend to all other means of stoppage,including spectacle blanks and blank flanges.

8.4 Venting requirements for individual products

Venting requirements for individual products are shown in column g, andadditional requirements in column o in the table of chapter 12.

8.5 Cargotank gasfreeingt

8.5.1 The arrangements for gas-freeing cargo tanks used for cargoes otherthan those for which open venting is permitted should be such as to minimizethe hazards due to the dispersal of f lammable or toxic vapours in the

" Reference is made to the Revised standards for the design, testing and locating of devices to

Chapter 9Environmental control

9.1 General

9.1.1 Vapour spaces within cargo tanks and, in some cases/ spaces sur-rounding cargo tanks may require to have specially controlled atmospneres.

9.1.2 There are four different types of control for cargo tanks, as follows:

.1 lnerting - by fi l l ing the cargo tank and associated piping systemsand, where speci f ied in chapter 15, the spaces surrounding thecargo tanks, with a gas or vapour which wil l not suppor{combust ion and which wi l l not react wi th the cargo, andmainta in ing that condi t ion.

.2 Padding - by fi l l ing the cargo tank and associated piping systemswith a l iquid, gas or vapour which separates the cargo from theai r , and mainta in ing that condi t ion.

.3 Drying - by fi l l ing the cargo tank and associated piping systemswith moisture-free gas or vapour with a dewpoint of -40"C orbelow at atmospher ic pressure, and mainta in ing that condi t ion.

.4 Ventilation - forced or natural.

15.13 Cargoes protected by additives

15.13.1 Certain cargoes with a reference in column o in the table of chapter17, by the nature of their chemical make-up, tend, under certain conditions oftemperature, exposure to air or contact with a catalyst, to undergo poly-merization, decomposition, oxidation or other chemical changes. Mitigationof this tendency is carried out by introducing small amounts of chemicaladditives into the l iquid cargo or controll ing the cargo-tank environment.

15.13.2 Ships carrying these cargoes should be so designed as to eliminatefrom the cargo tanks and cargo-handling system any material of constructionor contaminants which could act as a catalyst or destroy the inhibitor.

15.13.3 Care should be taken to ensure that these cargoes are sufficientlyprotected to prevent deleterious chemical change at all t imes during thevoyage. Ships carrying such cargoes should be provided with a certif icate ofprotection from the manufacturer, and kept during the voyage, specifying:

15.13.6 Venting systems should be of a design that eliminates blockage frompolymer bui ld-up. Vent ing equipment should be of a type that can bechecked periodically for adequacy of operation.

15.13.7 Crystall ization or solidif ication of cargoes normally carried in themolten state can lead to depletion of inhibitor in parts of the tank's contents.Subsequent remel t ing can thus y ie ld pockets of uninhib i ted l iqu id, wi th theaccompanying risk of dangerous polymerization. To prevent this, care shouldbe taken to ensure that at no time are such cargoes allowed to crystall ize orsolidify, either wholly or partially, in any part of the tank. Any required heatingarrangements should be such as to ensure that in no par t of the tank doescargo become overheated to such an extent that any dangerous polymer-ization can be init iated. lf the temperature from steam coils would induceoverheating, an indirect lowtemperature heating system should be used.

Chapter 1BList of chemicals to which the Code

t . tooes not appry

I The following are chemicals which have been reviewed for theirsafety and pollution hazards and determined not to present hazards to suchan extent as to warrant application of the Code. This may be used as a guidein considering bulk carriage of chemicals whose hazards have not yet beenevaluated.

2 Although the chemicals l isted in this chapter fall outside the scope ofthe Code, the attention of Administrations is drawn to the fact that somesafety precautions may be needed for their safe transportation. Accordingly,Administrations should prescribe appropriate safety requirements.

3 Some chemicals are identif ied as fall ing into pollution category Dand, therefore, subject to certain operational requirements of Annex ll ofMARPOL 73178.

4 Liquid mixtures which are provisionally assessed under regulation3(a) of Annex ll of MARPOL 73/78 as fall ing into pollution category D, andwhich do not present safety hazards, may be carried under the entry for"noxious l iquid, not otherwise specified" in this chapter. Similarly, thosemixtures provisonally assessed as fall ing outside pollution category A, B, C orD, and which do not present safety hazards, may be carried under the entryfor "non-noxious l iquid, not otherwise specified" in this chapter.

Chapter 19Requirements for ships engaged

in the incineration at sea ofliquid chemical waste

lg. l General

19.1.1 Chapters 1 to 16 apply to incinerator ships, as relevant, and assupplemented or modified by the provisions of this chapter.

lg.l.2 Information on the composition and the hazards of the waste to beinc inerated should be made avai lable to the Adminis t rat ion or por tAdministration, or both, as appropriate, which may prohibit carriage ofthose wastes deemed to be too hazardous to be carried in bulk..

19.1.3 The following additional definit ions apply:

.1 Incinerator space is a gastight space containing solely theincinerator and its associated auxil iaries.

.2 Incinerator blower space is a space containing the blowers whichsupply combustion air to the incinerator burners.

.3 London Convention 1972 means the Convention on the Preven-t ion of Mar ine Pol lu t ion by Dumping of Wastes and Other Mat terat Sea, 1972.

.4 Cargo area is that part of the ship defined in 1.3.5, excludingincinerators and chemical waste piping leading to the incinera-tors.

t9.1.4 Dur ing the per iodical and intermediate surveys requi red under1.5.2.1.2 and.3, a l l cargo tanks and the cargo p ip ing system should beinspected for corrosion and the remaining thickness of material should bedetermined. Where severely corrosive wastes have been carried, inspectionsof cargo tanks and the cargo piping system for corrosion should be heldannual ly and the remain ing th ickness of mater ia ls determined dur ing thoseinspections.

' The environmental aspects of incineration and dumping of wastes are regulated by rhe 1972

London Convention. The Sixteenth Consultative Meeting of Contracting Parties to the LondonConvention in November 1993 adopted amendments to the Convention (resolution1C.50(16)) which entered into force for all Contracting Parties on 21 February 1994, andwhich provide that incineration at sea of industrial wastes is prohibited.

"t 41

IBC Code

lg.2 Ship survival capability and location of cargo tanks

19.2.1 Ships subject to this chapter should comply with type 2 shipstandards and with the requirements for location of cargo tanks in type 2

ships.

,|9.2.2 Waste mixtures containing substances which would require a type 1

ship standard may be carried in type 2 ships if solely for the purpose of

inc inerat ion.

19.3 Ship arrangements

lS.3.l Liquid chemical wastes should not be stowed adjacent to oil fuel

tanks except those tanks containing oil fuel to be used exclusively for

inc inerat ion.

19.3.2 Tanks and pumps, other than those described in 19.3.3, which may

contain l iouids and which are to be used for the incineration process or for

washing cargo pipes and cargo tanks may be located adjacent to carSo tanksand should be located within the cargo area. The provisions of 3.1 shouldapply to such tanks and equipment to the same extent as they apply to cargo

tanks.

19.3.3 Where necessary, oil fuel tanks and fuel pumps directly feeding theinc inerator burners dur ing the process of pre-heat ing or support ingincineration may be located outside the cargo area provided the oil fuelused has a flashpoint above 60"C (closed-cup test). (See also 19.5.3.)

19.3.4 Liquids which have been used for cleaning cargo pipes and cargo

tanks as well as from pump-room drainage should be stored in a slop tank in

the cargo area, for disposal in conformity with the technical guidelines

annexed to the Dumping Convent ion. A cargo tank may be used as a s loptank. Pumps used for handl ing contaminated c leaning f lu ids should belocated in the cargo area.

19.3.5 Where necessary, compliance with 3.2.1 need not be required in sofar as accommodat ion spaces, serv ice spaces, contro l s tat ions and

machinery spaces other than those of category A may be permitted forwardof the cargo area, subject to an equivalent standard of safety and appropriatefire-extinguishing arrangements being provided to the satisfaction of theAdministration.

19.3.6 l f accommodat ion spaces, serv ice spaces, contro l s tat ions ormachinery spaces other than those of category A are located forward ofthe cargo area in accordance wi th 19.3.5, the requi rements of 3.2.3 shouldbe applied by analogy; i.e. the specified distances should be measured fromthe after end of a house located forward of the cargo area.

19.3.7 The incinerator should be located outside the external perimeter ofthe cargo area. Alternative arrangements may, however, be considered bythe Administration, provided an equivalent degree of safety is achieved.

1 4 2

Chapter 19 - Incineration of liquid chemical wastes

19.3.8 The effect which combustion gases may have on adequate visionfrom the navigating bridge, on air intakes and openings into accommodation,service and machinery spaces, and on deck working areas and passageways

should be considered.

t9.3.9 Access to the incinerator space should be from the open deck.However, the incinerator control room and incinerator blower space may

have direct access to the incinerator space provided that these spaces havean additional access from the open deck. Access openings of the incineratorspace should be fitted with self-closing gastight doors.

lg.4 Cargo containment and incinerator standards

19.4.1 Integral gravity tanks may be used for hazardous wastes.

19.4.2 The incinerator, including burners, should be designed and con-structed to safety standards acceptable to the Administration.' For materialsof construction the provisions of 6.1 apply.

t9.4.3 The steel structure of the incinerator, including supports and other

fixtures, should be designed for the most unfavourable static angle of heel

within the range of 0o to 30o, taking into account the dynamic loads due to

the ship 's mot ion.

19.4.4 Suitable brick l ining and insulation should be provided to ensure thatany temperature rise wil l not impair the strength of the incinerator structureor the functioning of the associated auxil iaries and instruments and wil l not

adversely affect personnel safety.

19.4.5 Means should be provided for measuring the temperature on the

outside furnace surfaces. Means for alarms should be provided to indicatewhen the temperature approved by the Administration is exceeded and theprocess of incineration has to be stopped.

tg.5 Cargo transfer

19.5.1 The requirements of 5.1 apply except that cargo piping should', as faras practicable, be fitted in the cargo area and that cargo piping leading to theinc inerator should:

.1 be fitted at least 760 mm inboard;

.2 if outside the cargo area, be on the open deck;

.3 be clearly marked; and

.4 be so designed as to allow draining and purging.

. The standards set out by the London Convention for the control of incineration of wastes andother matter at sea should also be observed.

Relevant decisions of theMSC and MEPC

Criteria for hazard evaluation of bulk chemicals

(approved by the MSC at itsforty-second session , 1980, and by ,

the MEPC at its twenty-first session, 1985)

I INTRODUCTION

1.1 The cr i ter ia aie intended for use when considering chemicals forinc lus ion in chapter Vl" and for ass igning appropr iate specia l requi rements.They should a lso be used by Adminis t rat ions for pre l iminary evaluat ion ofproducts which are not inc luded in the Code, pending thei r considerat ion bythe Sub-Commit tee on Bulk Chemicals.

1.2 Although the cr i ter ia have been developed to identi fy chemicalswhich appear to require special precautions, they should not be used asabsolutes. Human experience must always be taken into account. A certainamount of f lex ib i l i ty is a l lowable in deal ing wi th products which humanexperience shows may present greater or lesser hazards than the evaluationsystem su ggests.

1.3 For a number of products the suggested numerical values wi l t needadjustment to account for such physical propert ies as vapour pressure,sofubif i ty and density. For example, in est imating the inhalat ion hazard, theLCso wi l l provide a relat ive idea of the vapour toxici ty but the chemical 'svolat i l i ty and odour characterist ics also need to be considered for a real ist ichazard assessment. Products which are volat i le and offer l i t t le warning thattheir vapours are harmful (chloroform, benzene) are more dangerous thanthose having a low vapour pressure at ambient temperatures and a d is t inctodour (propionic ac id, ethanolamine) . Products wi th a h igher LCso shouldalso be considered, i f they are less dense than water and of low solubi l i ty,s ince they wi l l f loat i f sp i l led f rom a damaged tank and present a muchgreater inhalat ion hazard than those which are more dense and sink.Simi lar ly , the LDso (ora l ) cannot be used as the sole cr i ter ion for judging thehazard from ingest ion; products which are soluble in water and do not havea pronounced taste or odour are more l ikely to be ingested in larger doses.For this reason, products with a somewhat lower LDso but which have a verylow solubi l i ty in water , or a d is t inct taste, should not be inc luded. F inal ly , wi thregard to dermal toxici ty, some products are absorbed rapidly through theskin or absorbed with very l i t t le or no irr i tat ion (phenol, ani l ine). Products

chapter Vl should be taken as a reference to chapter 1 7.

with these characterist ics but a somewhat higher LDso (dermal) should beinc luded

1.4 The fol lowing cr i ter ia are intended for guidance only, and a certainf lexibi l i ty of approach must be al lowed for products which in real i ty maypresent greater or lesser hazards than the evaluat ion system suggests. Forthis reason, experience and good judgement are necessary. :

Guidelines for the uniform application ofthe survival requirements of the Bulk

Chemical Code and the Gas carrier Code

(Approved by the MSC at its forty-secondsessionr, l9B0*)

Preamble

The following should be considered as guidelines for the purpose of uniformappl icat ion of the surv iva l requi rements of the Bulk Chemical Code IBCHCode] and the Cas Carr ier Code. Alternat ive methods to the suggestedspecif ic programme of calculat ions and ptesgntat ion which demonstrate, tothe Administrat ion's sat isfact ion, compliance with the appl icable survivalcr i ter ia may be accepted

1.2 The dedicated service tanker wi l l require approval of calculat ionsbased on serv ice condi t ions proposed by the bui lder or owner, in which casethe cert i f icate of f i tness should be endorsed in respect of the condit ionsaccepted.

1.3 The inherentty safe ship is one that wi l l meet survival requirementswi th the ship assumed to be at a maximum draught and t r im, wi th a l lcompartments within the extent of damage assumed to be empty and withmaximum vert ical centre of gravity (adjusted for free l iquids)

2.1 , A systematic invest igat ion of damage-survival characterist ics shouldbe undertaken by making calculat ions to obta in the min imum required CMor maximum al lowable KC at a suf f ic ient number of draughts wi th in theoperat ing range to permi t the construct ion of a ser ies of curves of " requi red

2.3 Where it can be determined by inspection that the effect of certainassumed damage wi l l be less onerous than other assumed damage for whichcalculat ions are provided and curves prepared, then the invest igat ion of suchdamage cases may be d ispensed wi th.

2.4 The damage calculat ions should take account of:

3.2 The metacentr ic heights (CM), stabi l i ty levers (CZ) and centre ofgravity posit ions (KC) for judging the f inal survival condit ions should becalculated by the constant-displacement ( lost-buoyancy) method.

3.7 Lesser extent of damage should be taken into account only whereindicated by the presence of subdiv is ion extending in to the maximum extentof dam?ge, e.g. double-bottom tanks, side bal last tanks, side cargo tanks, fueltanks and void spaces. However, the fol lowing should be given attent ion:

.l lesser extent means the reduction of any'one of the threemaximum dimensions of damage singfy or in combinat ion andaf so the assessment of the effect of damage affecting anycombinat ion of compartments wi th in the maximum extent ofdamage.

.2 Where any damage involves the release of very heavy cargol iquid, then heel to the intact side of the ship may take place. Insuch cases the effect of lesser vertical extent of damage abovethe level of the tank top may result in the larger angle of heel,since otherwise the effect of cargo loss may be compensated byf lood water entering the double-bottom tanks on the damagedside.

3.8 The numl:er of calculat ions required to show compliance withsurvival requirements should be that necessary to obtain sufficient data forthe loading manLral and should be such that a l l loading condi t ions indicatedin paragraph 1 can be covered, i .e. no addit ional calculat ions should benecessary once the series of calculat ions has been executed.

3.9 Calculat ions to determine the displacement, tr im and the vert icalposit ion of the centre of gravity should be performed for each operat ionalloading condit ion. The vert ical posit ion of the centre of gravity should becorrected for free surface effects. One r1ethod would be to construct graphsshowing the free surface moments of the\ i ter ion angle for al l f i l t ing tevels ata specific gravity of one. The free surface moments for all tanks can then betaken from the graphs and be mult ipl ied by the cargo specif ic gravity.

3.10 In calculat ing the effect of free surface of consumable l iquids i t is tobe assumed that, for each type of l iquid, at least one transverse pair or as ingle centre l ine tank has maximurn f ree sur face, and the tank orcombinat ion of tanks to be taken into account is to be that where theeffect of free surfaces is the greatest; in each tank the centre of gravity of thecontents is to be taken at the centre of volume of the tank. The remainingtanks are to be assumed either completely empty or completely f i l led, andthe distr ibut ion of consumable l iquids among these tanks is to be such as toobtain the greatest possible height above the keel for the centre of gravity.

3. l f To take account of the presence of structure within cargo compart-ments, a permeabi l i ty of 0.95 should be assumed as stated in the Codes.Where, in part icular cases, such as the cargo tanks of gas carr iers, thisassumption would lead to a signif icant discrepancy in cargo-tank volume, i t ispreferable to calculate the permeabi l i ty taking into account actual tankstructure; the volume of tank insulat ion should then be calculated separatelyand an appropr iate permeabi l i ty appl ied.

3.12 Attent ion should be paid to the possibi l i ty of progressive f loodingthrough deck cargo pipes and common cargo-tank venti lat ion pipes i f theseare immersed at large angles of heel af ter damage.The possib i l i ty ofprogressive f looding through bal last p ip ing passing through the assumedextent of dam dge, where positive-action valves are not f itted to the ballastsystem at the open ends of the pipes in the tanks served, should beconsidered. Where remote control systems are f i t ted to bal last valves andthese controls pass through the assumed extent of dam d1e , then the effect ofdamage to the system should be considered to ensure that the valves wouldremain c losed in that event .

3.13 Where the ship is required to be capable of sustaining bottomdamage anywhere in i ts length (t) , the fol lowing method should be usedwhen damage is assumed to occur in the v ic in i ty of the 0.31 posi t ion f romthe forward perpendicular :

3.14 In ships carrying l iquef ied gases, large cargo tanks may be subdividedinto sect ions by centre l ine and t ransverse bulkheads which are l iqu id- t ightbut which have openings near the top of the tank. These openings wouldpermit spi l lage of cargo from one sect ion of the cargo tank to another whenthe ship is heeled where the tank is undgmaged, or loss of cargo due tospi l lage from sect ions of a damaged cargd tank. The effect of this spi l lageshould be taken into account in calculat ions and a lso in any calculat ion ofCM or KC for loading condi t ions where a"requi red CM" or "a l lowable KC"curve is to be used

3.15 In ships carrying l iquef ied gases, the abi l i ty of longitudinal bulkheadsfi t ted within cargo tanks to withstand the unequal pressures due to f loodingof one sect ion of cargo tank should only be considered in the f inal stage off lood ing.

Proposed amendments to regulat ion l l -2159 [see Note belowl

2 Cargo tank purging andf or gas-freeing*

Arrangements for purging andf or gas-freeing shatl be such as to minimize thehazards due to the dispersal of f lammable vapours in the atmosphere and toflammable mixtures in a cargo tank. Accordingly: :

.1 When the ship is provided with an inert gas system, the cargotanks shal l f i rst be purged in accordance with the provisions of

l; ? il 1* t : i ii i H i'i :# ff "# :T' :J : l i tT;';:: ;i, J : i,T ::Thereafter, gas-freeing may take place at the cargo tank deck level.

.2 When the ship is not provided with an inert gas system, the opera-t ion shal l be such that the f lammable vapour is d ischarged in i t ia l ly :

.2 .1 through the vent out le ts as speci f ied in paragraph 1.9; or

.2.2 through out lets at least 2 m above the cargo tank deck levelwith a vert ical eff lux velocity of at least 30 mls maintainedduring the gas-freeing operat ion; or .

,

with a vert ical eff lux velocity of at least 20 mls and which areprotected by suitable devices to prevent the passage of f lame.

When the flammable vapour concentration at the outlet has been reduced to30% of the lower flammable l imit, gas-freeing may thereafter be continued atcargo tank deck level.

* Refer to the Revised standards for the design, testing and locating of devices to prevent the

passage of f lame into cargo tanks in tankers (MSClCirc.373lRev. 1) and to Revised factors tobe taken into consideration when designing cargo tank venting and gas-freeing arrangements(MSC/Cuc. 45OlRev. 1) .

Revised factors to be taken

cargo tank venting and gas-freeing arrangements

I The amendments to the Internat ionat Convent ion for the Safety of

L i fe at Sea, 197 4 (SOLAS 197 4) , inc lude requirements for f i re safety

measures fo r tankers in regu la t ions l l -2159 and 62 , and the IBC and ICC

Codes. These amendments contain arrangements for vent ing, iner t ing,

purg ing , gas- f ree ing and vent i la t ion .

2 The Sub-Commit tee on Fi re Protect ion has considered problems

associated wi th the design of cargo tank vent ing and gas- f reeing arrange-

ments and the Mar i t ime Safety Commit tee has approved the main factors to

be considered for the design of the arrangements in 1 above as fo l lows:

.1 Maximum loading/discharge rate: the venting system should bedesigned to take in to considerat ion the maximum permiss ib leloadingldischarge rate for each cargo tank and in the case of acombined venting syste f f i , for each group of tanks. These loadingand discharge rates should also be used for the design of the inert

, gas system, regulat ion l l -2162.3.1.

.2 Cas evolut ion. ' regulat ion l l -2159.1.9.5 requires at least 25% to beadded to the maximum loading rate to account for the increasedvolume dure to gas evolut ion from the cargo. A higher gasevolut ion factor may be considered for highly volat i le cargoes.

.3 Pressure /oss across devices: data relating to pressure loss across, devices to prevent the passage of f lame, approved in accordance

with MSC/Circ. 373 and referred to in regulat ion l l -2159.1 .5, areto be considered in the design of the vent ing system. Foul ing ofdevices should be taken into account.

.4 Pressure /oss in the venting systemi pressure loss calculations ofsystems including pipes, valves, bends, f i t t ings, etc., should bemade to ensure that the pressure inside the cargo tanks does notexceed the pressure these tanks are designed to withstand, takingin to cons idera t ion .2 and.3 above. In the case where a combinedventing system is used in associat ion with loading of cargo tankssimultaneously, the combined effect of vapour pressure gener-ated in the tanks and vent ing system should be considered.

.5 Pressure at which the vents open: the init ial opening pressure ofthe vent va lves should be considered in select ing the appropr iatevalves for the venting system.

.6 Density of the gaseous mixture: the maximum density of thegaseous mixtures l ikely to be encountered in the cargo tanks,

overfill: where overflow control systemsis to be given to the dynamic condit ion

.8 Location of vent outlets: horizontal and vertical distances of thevent out lets are to be in accordance with regulat ion l l -2159. i

.9 Types of venting systems: due regard is to be given to cargo' segregation when considering a venting system or inert gas

system common to more than one tank. Where the inert gas mainis designed for vent ing of cargo tanks, addit ional means forventing of these tanks are to be in accordance with regulat ion l l -2162. 1 1 .3 .

.10 Vent dra in ing arrangements; the dra in ing arrangements forventing systems are to be designed in accordance with regulat ionl l -2159.1 .4.

.11 Cas-freeing: in designing a gas-freeing system in conformity withproposed regulat ion l l -2159.2.2.2 and 59.2.2.3 (see annex*) inorder to achieve the required exit velocit ies, the fol lowing shouldbe considered:

. l the f low characterist ics of the fans to be used;

.2 the pressure losses created by the design of a particulartank 's in lets and out le ts ;

.3 1".ffi1::::jTil:tle

in the fan driving medium (e.g water

.4 the densit ies of the cargo vapourlair mixtures for the range ofcargoes to be carr ied.

3 Repairs and renewal of the venting system should conform to theoriginal design parameters. Factors in the above paragraphs are to be takeninto considerat ion when modif icat ions are carr ied out to the venting system.

4 The master is to be provided with a manual containing informationrelat ing to the maximum loading and unloading rates for each tank or groupof tanks establ ished during the design of the venting system, ds per para-graph 1 above.

Procedures for inspectiotr, cleaning, passivationand loading of tanks for the carriage of

hydrogen peroxide solutions B- 60"/", which havecontained other cargo€s, or for the carriage of

other cargoes after the carriageof hydrogen peroxide* .

I Tanks having contained cargoes other than hydrogen peroxideshould be inspected, cleaned and passivated before re-use for the transportof hydrogen peroxide solut ions. The procedures for inspect ion and cleaning,as g iven in paragraphs 1.1 to 1.7 below, apply to both sta in less steel andpure a lumin ium tanks (see paragraph 4 .20 .16 o f the BCH Code andparagraph 15.5.15 of the IBC Code). Procedures for passivat ion are g iven inparagraph 1.8 for s ta in less steel and 1.9 for a luminium. Unless otherwisespecif ied, al l steps apply to the tanks and to al l associated equipment havingbeen in contact with the other cargo.

1.1 After unloading the previous cargo the tank should be rendered safeand inspected for any residues, scale and rust.

1.2 Tanks and associated equipment should be washed with cleanfi l tered water. The water to be used should at least have the qual i ty ofpotable water with a low chlor ine content.

1.3 Trace residues and vapours of the previous cargo should be removedby steaming of tank and equipment .

1.4 Tank and equipment are washed again with clean water (qual i ty asabove) and dried, using f i l tered, oi l - free air .

1.5 The atmosphere in the tank should be sampled and invest igated forthe presence of organic vapours and oxygen concentrat ion.

1.6 The tank should be checked again by v isual inspect ion for res idues ofthe previous cargo, scale and rust as wel l as for any smell of the previouscar8o.

1,7 l f inspect ion or measurements indicate the presence of residues ofthe previous cargo or i ts vapours, steps 1.2 to 1.4 should be repeated.

1.8 Tank and equipment made f rom sta in less steel which have conta inedother cargoes than hydrogen peroxide or which have been under repairshould be cleaned and passivated, regardless of any previous passivat ion,according to the fol lowing procedure:

Fatty and oi ly residues should be removed by the use ofappropriate organic solvents or detergent solut ions in water.The use of ch lor ine-conta in ing compounds should be avoided asthey can seriously interfere with passivat ion

The res idues of the degreasing agent shoutd be removed,fol lowed by a washing with water.

In the next step, scale and rust should be removed by theappl icat ion of acid (e.g. a mixture of ni tr ic and hydrof luoric acids),fol lowed again by a washing with clean water.

Al l the metal sur faces which can come into contact wi thhydrogen peroxide should be passivated by the appl icat ion ofni tr i . acid of a concentrat ion between 10 and 35% by weight.The nitr ic acid must be free from heavy metals, other oxidizingagents or hydrogen f luoride. The passivat ion process shouldcont inue for B to 24 hours, depending upon the concentrat ion ofac id, the ambient temperature and other factors. Dur ing th is t imea continuous contact between the surfaces to be passivated andthe n i t r ic ac id should be ensured. In the case of large sur faces th ismay be achieved by rec i rcu lat ing the ac id.Hydrogen gas may beevolved in the passivat ion process, leading to the presence of anexplos ive atmosphere in the tanks. Therefore, appropr iatemeasures must be taken to avoid the bui ld-up or the igni t ion ofsuch an atmosphere.

After passivat ion the surfaces shoutd be thoroushly washed withclean f i l tered water. The washing process should be repeatedunt i l the ef f luent water has the same pH value as the incomingwater.

Surfaces treated according to the above steps may cause somedecompos i t ion when coming in to contac t w i th hydrogenperoxide for the f i rst t ime.

Re/eva nt decisions of the MSC and MEPC

. l The tank should be washed wi th a solut ion of a sulphonateddetergent in hot water, fol lowed by a washing with water.

The surface should then be treated for 15 to 20 minutes with asolut ion of sodium hydroxide of a concentrat ion of 7"/" by weightor treated for a longer period with a less concentrated solut ion(e.g. for 12 hours wi th 0.4 to 0.5% sodium hydroxide) . To preventexcessive corrosion at the bottom of the tank when treat ing withmore concentrated solut ions of sodium hydroxide, water shouldbe added cont inuously to d i lu te the sodium hydroxide solut ionwhich col lects there.

The tank should be thoroughly washed with clean, f i l tered water.As soon as possible after washing, the surface should bepassivated by the appl icat ion of ni tr ic acid of a concentrat ionbetween 30 and 35% by weight. The passivat ion process shouldcont inue for 16 to 24 hours. Dur ing th is t ime a cont inous contactbetween the surfaces to be passivated and the nitr ic acid shouldbe ensured.

After passivat ion the surfaces should be thorouShly washed withclean, f i l tered water. The washing process should be repeatedunt i l the ef f luent water has the same pH value as the incomingwater.

A v isual inspect ion should be made to ensure that a l l sur faceshave been treated. l t is recommended that an addit ional f lushingis carr ied out for a min imum of 24 hours wi th d i lu te hydrogenperoxide solut ion of a concentract ion approximately 3% byweight .

5J Ships' cargo hoses

1 Rep/ace existing paragraph 5.7.3 by the following:

"5J.3 For cargo hoses installed on board ships on or after 1 July2OO2, each new type of cargo hose, complete with end-fitt ings,should be prototype-tested at a normal ambient temperature with2OO pressure cycles from zero to at least twice the specifiedmaximum working pressure. After this cycle pressure test has beencarried out, the prototype test should demonstrate a burstingpressure of at least 5 times its specified maximum working pressureat the extreme service temperature. Hoses used for prototypetesting should not be used for cargo service. Thereafter, beforebeing placed in service, each new length of cargo hose producedshould be hydrostatically tested at ambient temperature to apressure not less than 1.5 t imes i ts speci f ied maximum work ingpressure but not more than two-fifths of its bursting pressure. Thehose should be stencil led or otherwise marked with the date oftesting, its specified maximum working pressure and, if used inservices other than the ambient temperature services, its maximumand minimum service temperature, as applicable. The specifiedmaximum working pressure should not be less than 10 bar gauge."

Carriage under water pad

15.3.1 Provision should be made to maintain a water oad in thecargo tank dur ing loading, unloading and t ransi t . In addi t ion, asuitable inert gas pad should be maintained in the ullage spacedur ing t ransi t .

15.3.2 All openings should be in the top of the tank, above thedeck.

15.3.3 Loading l ines should terminate near the bottom of the tank.

15.3.4 A standard u l lage opening should be provided foremergency sounding.

15.3.5 Cargo p ip ing and vent l ines should be independent ofpiping and vent l ines used for other cargo.

15.3.6 Pumps may be used for discharging cargo, provided theyare of the deepwell or hydraulically driven submersible types. Themeans of dr iv ing a deepwel l pump should not present a source ofigni t ion for carbon d isulphide and should not employ equipmentthat may exceed a temperature of 80"C.

15.3.7 lf a cargo discharge pump is used, it should be insertedthrough a cylindrical well extending from the tank top to a pointnear the tank bottom. A water pad should be formed in this wellbefore attempting pump removal unless the tank has been certif iedas gas-free.

15.3.8 Water or iner t gas d isplacement may be used fordischarging cargo, provided the cargo system is designed for theexpected pressure and temperature.

15.3.9 Safety relief valves should be of stainless steel construction.

15.3.10 Because of i ts low igni t ion temperature and c loseclearances required to arrest its f lame propagation, only intrinsicallysafe systems and circuits should be permitted in the hazardouslocations described in 1O.2.3.

Carriage under suitable inert gas pad

l5.3. t l Carbon d isulphide should be carr ied in independent tankswith a design pressure of not less than 0.6 bar gauge.

15.3.12 All openings should be located on the top of the tank,above the deck.

15.3.13 Caskets used in the containment system should be of amaterial which does not react with. or dissolve in. carbondisulohide.

15.3.14 Threaded joints should not be permitted in the cargoconta inment system, inc luding the vapour l ines.

15.3.15 Prior to loading, the tank(s) should be inerted with suitableinert gas unti l the oxygen level is 2% by volume or lower. Meansshould be provided to automatically maintain a positive pressure inthe tank using suitable inert gas during loading, transport anddischarge. The system should be able to maintain this positivepressure between 0.1 and O.2 bar gauge, and should be remotelymonitored and fitted with over-/under-pressure alarms.

15.3.16 Hold spaces surrounding an independent tank carry ingcarbon d isulphide should bre iner ted by a sui table iner t gas unt i l theoxygen level is 2"h or less. Means should be provided to monitorand maintain this condition throughout the voyage. Means shouldalso be provided to sample these spaces for carbon disulphidevaoour.

15.3.17 Carbon d isulphide should be loaded, t ransported anddischarged in such a manner that venting to the atmosphere doesnot occur . l f carbon d isulphide vapour is returned to shore dur ingloading or to the ship during discharge, the vapour return systemshould be independent of all other containment systems.

15.3.18 Carbon d isulphide should be d ischarged only by sub-merged deepwell pumps or by a suitable inert gas displacement.The submerged deepwell pumps should be operated in a way thatprevents heat bui ld-up in the pump. The pump should a lso beequipped wi th a temperature sensor in the pump housing wi thremote readout and alarm in the cargo control room. The alarmshould be set at B0'C. The pump should also be fitted with anautomatic shut-down device, if the tank pressure falls belowatmospheric pressure during the discharge.

15.3.19 Air should not be allowed to enter the cargo tank, cargopump or l ines whi le carbon d isulphide is conta ined in the system.

15.3.20 No other cargo handl ing, tank c leaning or debal last ingshould take place concurrent with loading or discharge of carbondisulohide.

15.3.21 A water spray system of sufficient capacity should beprovided to blanket effectively the area surrounding the loadingmanifold, the exposed deck piping associated with producthandl ing and the tank domes. The arrangement of p ip ing andnozzles should be such as to give a uniform distribution rate of1O llm2 lmin Remote manual operation should be arranged suchthat remote starting of pumps supplying the water-spray systemand remote operation of any normally closed valves in the systemcan be carried out from a suitable location outside the cargo areaadjacent to the accommodation spaces and readily accessible andoperable in the event of f ire in the areas protected. The water-spray

system should be capable of both local and remote manualoperation, and the arrangement should ensure that any spil ledcargo is washed away. Additionally, a water hose with pressure tothe nozzle when atmospheric temperature permits, should beconnected ready for immediate use during loading and unloadingooerat ions.

15.3.22 No cargo tanks should be more than 98% liquid-full at thereference temperature (R).

15.3.23 The maximum volume (VL) of cargo to be loaded in a tankshould be:
