REVIEW OF AMENDMENTS IN RELATION TO PREVIOUSEDITION OF THE RULES

RULES FOR THE CLASSIFICATION OF SHIPSPart 27 – Chemical tankers

Due to significant changes in respect to the Rules for technical supervision of sea-going ships, Part 27 –Chemical tankers, 2002 edition, deriving from IBC Code 2004 and subsequent amendments, changes and correctionshave not been indicated throughout the text.

NOTE: Due to change of the structure of the Technical Rules (separation of statutory from classificationrules), previously issued Rules for technical supervision of sea-going ships, Part 27 – Chemical tankers, are now re-categorized as a part of the classification rules.

By such change, Part 27 – Chemical tankers, will no longer be issued as a part of the Rules for technicalsupervision of sea-going ships.

2 SHIP SURVIVALCAPABILITY AND LOCATION OF

CARGO TANKS

2.1 GENERAL

2.1.1 Ships, subject to this Part of the Rules, shall sur-vive the normal effects of flooding following assumed hulldamage caused by some external force (see 2.5). In addition,to safeguard the ship and the environment, the cargo tanks ofcertain types of ships (see 2.1.2) shall be protected from pene-tration in the case of minor damage to the ship resulting, forexample, from contact with a jetty or tug, and given a measureof protection from damage in the case of collision or strand-ing, by locating them at specified minimum distances inboardfrom the ship's shell plating (see 2.6). Both the assumed dam-age and the proximity of the cargo tanks to the ship's shellshall be dependent upon the degree of hazard presented by theproducts to be carried.

2.1.2 Ships, subject to this Part of the Rules, shall bedesigned to one of the following standards:

.1 A type 1 ship is a chemical tanker intendedto transport Chapter 17 products with verysevere environmental and safety hazardswhich require maximum preventive meas-ures to preclude an escape of such cargo.

.2 A type 2 ship is a chemical tanker intendedto transport Chapter 17 products with ap-preciably severe environmental and safetyhazards which require significant preven-tive measures to preclude an escape ofsuch cargo.

.3 A type 3 ship is a chemical tanker intendedto transport Chapter 17 products with suf-ficiently severe environmental and safetyhazards which require a moderate degreeof containment to increase survival capa-bility in a damaged condition.

Thus, a type 1 ship is a chemical tanker intendedfor the transportation of products considered to present thegreatest overall hazard and type 2 and type 3 for products ofprogressively lesser hazards. Accordingly, a type 1 ship shallsurvive the most severe standard of damage and its cargotanks shall be located at the maximum prescribed distance in-board from the shell plating.

2.1.3 The ship type required for individual products isindicated in column e in the table of Chapter 17.

2.1.4 If a ship is intended to carry more than oneproduct listed in Chapter 17, the standard of damage shall cor-respond to that product having the most stringent ship type re-quirement. The requirements for the location of individualcargo tanks, however, are those for ship types related to the re-spective products intended to be carried.

2.2 FREEBOARD AND INTACTSTABILITY

2.2.1 Ships subject to this Part of the Rules may be as-signed the minimum freeboard permitted by the InternationalConvention on Load Lines in force. However, the draught as-sociated with the assignment shall not be greater than themaximum draught otherwise permitted by this Part of theRules.

2.2.2 The stability of the ship in all seagoing condi-tions shall be to a standard which is acceptable to the Register(see Rules, Part 4 – Stability, 3.4).

2.2.3 When calculating the effect of free surfaces ofconsumable liquids for loading conditions it shall be assumedthat, for each type of liquid, at least one transverse pair or asingle centre tank has a free surface and the tank or combina-tion of tanks to be taken into account shall be those where theeffect of free surfaces is the greatest. The free surface effect inundamaged compartments shall be calculated by a method ac-ceptable to the (see Rules, Part 4 – Stability, 3.4).

2.2.4 Solid ballast shall not normally be used in dou-ble-bottom spaces in the cargo area. Where, however, becauseof stability considerations, the fitting of solid ballast in suchspaces becomes unavoidable, then its disposition shall be gov-erned by the need to ensure that the impact loads resultingfrom bottom damage are not directly transmitted to the cargotank structure.

2.2.5 The master of the ship shall be supplied with aloading and stability information booklet. This booklet shallcontain details of typical service and ballast conditions, provi-sions for evaluating other conditions of loading and a sum-mary of the ship's survival capabilities (see MSCCirc.406/Rev.1). In addition, the booklet shall contain suffi-cient information to enable the master to load and operate theship in a safe and seaworthy manner, to the satisfaction of theRegister (see Rules, Part 4 – Stability, 1.5).

2.2.6 No loading conditions, other than those con-tained in the approved Loading and Stability InformationBooklet, shall be used unless previously approved by theRegister.

Alternatively, such cases may be examined bythe master or a responsible officer when a loading instrumentapproved in accordance with requirements specified in Rules,Part 2 – Hull, 4.1 is installed onboard.

2.2.7 In no case shall be distance between the top ofsolid ballast and cargo tank bottom be less than the assumedmaximum vertical extent of the bottom damage.

The solid ballast shall be of concrete block orsimilar materials which can be fitted securely.

2.3 SHIPSIDE DISCHARGES BELOWTHE FREEBOARD DECK

2.3.1 The provision and control of valves fitted to dis-charges led through the shell from spaces below the freeboarddeck or from within the super-structures and deck-houses onthe freeboard deck fitted with weathertight doors shall complywith the requirements of the relevant regulation of the Inter-


2009

national Convention on Load Lines in force, except that thechoice of valves shall be limited to:

.1 one automatic non-return valve with apositive means of closing from above thefreeboard deck; or

.2 where the vertical distance from the sum-mer load waterline to the inboard end ofthe discharge pipe exceeds 0.01L, twoautomatic non-return valves without posi-tive means of closing, provided that theinboard valve is always accessible for ex-amination under service conditions.

2.3.2 For the purpose of this chapter, “summer loadline“ and “freeboard deck“ have the meanings as defined inthe International Convention on Load Lines in force.

2.3.3 The automatic non-return valves referred to in2.3.1.1 and 2.3.1.2 shall be fully effective in preventing ad-mission of water into the ship, taking into account the sinkage,trim and heel in survival requirements in 2.9, and shall complywith recognized standards (see Rules, Part 8 – Piping, 1.4 and1.5).

2.3.4 The requirements in 2.3.1 do not apply to theoverboard discharges led through the shell from within super-structures and deck-houses located above the second super-structure deck.

2.4 CONDITIONS OF LOADING

2.4.1 Damage survival capability shall be investigatedon the basis of loading information submitted to the Registerfor all anticipated conditions of loading and variations indraught and trim. Ballast conditions where the chemical tankeris not carrying products covered by this Part of the Rules, or iscarrying only residues of such products, need not be consid-ered.

2.5 DAMAGE ASSUMPTIONS

2.5.1 The assumed maximum extent of damage shallbe as prescribed in Table 2.5.1-1:

2.5.2 If any damage of a lesser extent than the maxi-mum damage specified in 2.5.1 would result in a more severecondition, such damage shall be considered.

2009

2.6 LOCATION OF CARGO TANKS

2.6.1 Cargo tanks shall be located at the followingdistances inboard:

.1 Type 1 ships: from the side shell plating,not less than the transverse extent ofdamage specified in 2.5.1.1.2, and fromthe moulded line of the bottom shellplating at centreline, not less than thevertical extent of damage specified in2.5.1.2.3, and nowhere less than 760 mmfrom the shell plating. This requirementdoes not apply to the tanks for dilutedslops arising from tank washing.

.2 Type 2 ships: from the moulded line ofthe bottom shell plating at centreline, notless than the vertical extent of damagespecified in 2.5.1.2.3, and nowhere lessthan 760 mm from the shell plating. Thisrequirement does not apply to the tanksfor diluted slops arising from tank wash-ing.

.3 Type 3 ships: no requirement.

2.6.2 Except for type 1 ships, suction wells installedin cargo tanks may protrude into the vertical extent of bottomdamage specified in 2.5.1.2.3 provided that such wells are assmall as practicable and the protrusion below the inner bot-tom plating does not exceed 25% of the depth of the doublebottom or 350 mm, whichever is less. Where there is no dou-ble bottom, the protrusion of the suction well of independenttanks below the upper limit of bottom damage shall not ex-ceed 350 mm. Suction wells installed in accordance with thisparagraph may be ignored in determining the compartmentsaffected by damage.

2.6.3 Any cargo tank, irrespective of its location,may be used for collecting contaminated cargo pump roombilge water or tank washings, as an exception to the require-ments in 2.6.1.1 and .2.

2.6.4 In general, the area of suction wells shall not begreater than that required to accommodate cargo pumps, suc-tion pipes, valves, heating coils etc., and to ensure efficientflow and the necessary access for cleaning and maintenance.

The requirements for the total retain quantity ofresidue not in excess of 0.075 m3 specified in 12.3 of AnnexII of MARPOL 73/78 shall also be taken into consideration.

2.7 FLOODING ASSUMPTIONS

2.7.1 The requirements of 2.9 shall be confirmed bycalculations which take into consideration the design charac-teristics of the ship; the arrangements, configuration andcontents of the damaged compartments; the distribution,relative densities and the free surface effects of liquids; andthe draught and trim for all conditions of loading.

2.7.2 The permeabilities of spaces assumed to bedamaged shall be as follows:

Spaces Permeabilities

Appropriated to stores 0.60

Occupied by accommodation 0.95

Occupied by machinery 0.85

Voids 0.95

Intended for consumable liquids 0 to 0.95*

Intended for other liquids 0 to 0.95*

*Note: The permeability of partially filled compartments shall beconsistent with the amount of liquid carried in the compartment.

2.7.3 Wherever damage penetrates a tank containingliquids it shall be assumed that the contents are completelylost from that compartment and replaced by salt water up tothe level of the final plane of equilibrium.

2.7.4 Every watertight division within the maximumextent of damage defined in 2.5.1 and considered to havesustained damage in positions given in 2.8.1 shall be assumedto be penetrated. Where damage less than the maximum isbeing considered in accordance with 2.5.2, only watertightdivisions or combinations of watertight divisions within theenvelope of such lesser damage shall be assumed to be pene-trated.

2.7.5 The ship shall be so designed as to keep un-symmetrical flooding to the minimum consistent with effi-cient arrangements.

2.7.6 Equalization arrangements requiring mechani-cal aids such as valves or cross-levelling pipes, if fitted, shallnot be considered for the purpose of reducing an angle ofheel or attaining the minimum range of residual stability tomeet the requirements of 2.9 and sufficient residual stabilityshall be maintained during all stages where equalization isused. Spaces which are linked by ducts of large cross-sectional area may be considered to be common.

2.7.7 If pipes, ducts, trunks or tunnels are situatedwithin the assumed extent of damage penetration, as definedin 2.5, arrangements shall be such that progressive floodingcannot thereby extend to compartments other than those as-sumed to be flooded for each case of damage.

2.7.8 The buoyancy of any superstructure directlyabove the side damage shall be disregarded. The unfloodedparts of superstructures beyond the extent of damage, how-ever, may be taken into consideration provided that:

.1 they are separated from the damagedspace by watertight divisions and the re-quirements of 2.9.3 in respect of theseintact spaces are complied with; and

.2 openings in such divisions are capable ofbeing closed by remotely operated slidingwatertight doors from a readily accessibleplace in case of damage and unprotectedopenings are not immersed within theminimum range of residual stability re-quired in 2.9; however, the immersion ofany other openings capable of being se-curely closed weathertight at final equi-librium may be permitted.

2.7.9 Tunnels, ducts, pipes, doors, bulkheads anddecks which might form watertight boundaries of intact


2009

spaces in the case of assumed damage (see 2.5.1) shall haveminimum strength adequate to withstand the pressure heightcorresponding to the deepest equilibrium waterline in dam-aged conditions.

2.7.10 The calculations made as required in 2.7.1 shallallow for preparing maximum permissible VCG-curves (off-sets) or, alternatively, the minimum permissible metacentricheights which shall be included in the stability manual.

It is recommended to prepare individual curves(offsets) for each considered damage case, except those casesfor which can be demonstrated that will not result in a severecondition.

2.7.11 When preferred by the Owner, damage stabilitycalculations may be performed for a limited number of load-ing conditions shown in the approved Loading and StabilityInformation Booklet. In this case the curves (offsets) pre-scribed in 2.7.10 are not required and the loading limitationsshall be appended to the International Certificate of Fitnessfor the Carriage of Dangerous Chemicals in Bulk.

2.7.12 Where damage survival capability criteria (see2.9) satisfies for conditional loading condition as specified in2.7.13 the requirements for calculations prescribed in 2.7.10and 2.7.11 may be dispensed with.

2.7.13 The conditional loading condition shall corre-spond to the loading condition with a maximum draught ofthe ship and maximum permissible trim (by stern or by bow,whichever gives more unfavourable results) as well as high-est possible centre of gravity above base line (taking into ac-count free surface effect) and empty damaged compartmentsfor each considered damage case.

2.8 STANDARD OF DAMAGE

2.8.1 Ships shall be capable of surviving the damageindicated in 2.5 with the flooding assumptions in 2.7 to theextent determined by the ship's type according to the follow-ing standards:

.1 A type 1 ship shall be assumed to sustaindamage anywhere in its length.

.2 A type 2 ship of more than 150 m inlength shall be assumed to sustain dam-age anywhere in its length.

.3 A type 2 ship of 150 m in length or lessshall be assumed to sustain damage any-where in its length except involving eitherof the bulkheads bounding a machineryspace located aft.

.5 A type 3 ship of 125 m in length or morebut not exceeding 225 m in length shallbe assumed to sustain damage anywherein its length except involving either of thebulkheads bounding a machinery spacelocated aft.

.6 A type 3 ship below 125 m in length shallbe assumed to sustain damage anywherein its length except involving damage tothe machinery space when located aft.However, the ability to survive the

flooding of the machinery space shall beconsidered by the Register.

2.8.2 In the case of small type 2 and type 3 shipswhich do not comply in all respects with the appropriate re-quirements of 2.8.1.3 and 2.8.1.6, special dispensation mayonly be considered by the Register provided that alternativemeasures can be taken which maintain the same degree ofsafety. The nature of the alternative measures shall be ap-proved and clearly stated and be available to the port Ad-ministration. Any such dispensation shall be duly noted onthe International Certificate of Fitness for the Carriage ofDangerous Chemicals in Bulk.

2.8.3 The longitudinal extent of damage to the super-structure in the case of side damage where the machineryspace is regarded as one-space flooding in 2.8.1, shall gener-ally to be the same as the longitudinal extent of the side dam-age to the machinery space (see Figure 2.8.3-1).

Figure 2.8.3-1Longitudinal extent of damage to superstructure

2.8.4 If the concept of a stepped machinery spaceforward bulkhead is applied (see 3.2.1), for damage stabilityconsiderations in 2.8.1.3 and 5 when such a bulkhead con-tains a step more than 3 m in length, damage shall be treatedas shown in Figure 2.8.4-1

Figure 2.8.4-1Damage to stepped machinery space forward bulkhead


2009

2.8.5 For the type 3 ships of less than 125 m inlength, but no less than 70 m, the ability to survive theflooding of the machinery space in accordance with survivalrequirements in 2.9 shall apply only, as a minimum.

Alternative proposals for equivalent survivalability may be considered by the Register.

2.8.6 In the case of type 2 and type 3 ships of lessthan 70 m in length special dispensation with regard to thecompliance with the appropriate requirements of 2.8.1.3 and2.8.1.6 (see 2.8.2) shall be in accordance with the following:

.1 Assumed extent of damage shall be in ac-cordance with 2.5 and 2.8.1.3 and 2.8.1.6.

.2 Downflooding point and angle of heelshall be in accordance with 2.9.2 and2.9.3.

.3 The area with positive sign of the rightinglever curve within the range from the ar-bitrary point between the final stage ofequilibrium after flooding and 25° (or 30°if no deck immersion occurs) to 20° shallbe not less than 0.0175 m⋅rad.

.4 The maximum value of GZ is not speci-fied.

2.9 SURVIVAL REQUIREMENTS

2.9.1 Ships subject to this Part of the Rules shall becapable of surviving the assumed damage specified in 2.5 tothe standard provided in 2.8 in a condition of stable equilib-rium and shall satisfy the criteria as specified in 2.9.2 and2.9.3.

2.9.2 In any stage of flooding:.1 the waterline, taking into account sink-

age, heel and trim, shall be below thelower edge of any opening through whichprogressive flooding or downfloodingmay take place. Such openings shall in-clude air pipes and openings which areclosed by means of weathertight doors orhatch covers and may exclude thoseopenings closed by means of watertightmanhole covers and watertight flushscuttles, small watertight cargo tank hatchcovers which maintain the high integrityof the deck, remotely operated watertightsliding doors, and sidescuttles of the non-opening type;

.2 the maximum angle of heel due to un-symmetrical flooding shall not exceed25°, except that this angle may be in-creased to 30° if no deck immersionocurs;

.3 the residual stability during intermediatestages of flooding shall be to the satisfac-tion of the Register. However, it shallnever be significantly less than that re-quired by 2.9.3.

2.9.3 At final equilibrium after flooding:.1 the righting-lever curve shall have a

minimum range of 20° beyond the posi-tion of equilibrium in association with amaximum residual righting lever of at

least 0.1 m within the 20° range; the areaunder the curve within this range shall notbe less than 0.0175 m radians. Unpro-tected openings shall not be immersedwithin this range unless the space con-cerned is assumed to be flooded. Withinthis range, the immersion of any of theopenings listed in 2.9.2.1 and otheropenings capable of being closed weath-ertight may be permitted; and

.2 the emergency source of power shall becapable of operating.

2.9.4 The words “to the satisfaction of the Register”in 2.9.2.3 means as follows. In ordinary cases, the final stageof flooding is considered most severe, but the most severecondition may be encountered during intermediate stages offlooding involving replacement of sea water in the damagedspace. In this connection, stability during such intermediatestages of flooding shall be considered when specifically re-quested by the Register.

2.9.5 The survival requirements at the final stage ofequilibrium after flooding shall be in accordance with Figure2.9.5-1.

Figure 2.9.5-1Stability criteria at final equilibrium after flooding

Note: The initial point of calculation of the stability range atan angle of heel of 20° may be taken arbitrarily at anyintermediate point between the angle of heel at the finalstage of equilibrium and the maximum angle of heel.

8.1.6 Ships constructed on or after 1 July 1986, butbefore 1 July 2002 shall comply with the requirements of8.3.3.

8.2 CARGO TANK VENTING

8.2.1 All cargo tanks shall be provided with a ventingsystem appropriate to the cargo being carried and these sys-tems shall be independent of the air pipes and venting systemsof all other compartments of the ship. Tank venting systemsshall be designed so as to minimize the possibility of cargovapour accumulating about the decks, entering accommoda-tion, service and machinery spaces and control stations and, inthe case of flammable vapours, entering or collecting in spacesor areas containing sources of ignition. Tank venting systemsshall be arranged to prevent entrance of water into the cargotanks and, at the same time, vent outlets shall direct the vapourdischarge upwards in the form of unimpeded jets.

8.2.2 The venting systems shall be connected to thetop of each cargo tank and as far as practicable the cargo ventlines shall be self-draining back to the cargo tanks under allnormal operational conditions of list and trim. Where it is nec-essary to drain venting systems above the level of any pres-sure/vacuum valve, capped or plugged drain cocks shall beprovided.

8.2.3 Provision shall be made to ensure that the liquidhead in any tank does not exceed the design head of the tank.Suitable high-level alarms, overflow control systems or spillvalves, together with gauging and tank filling procedures, maybe accepted for this purpose. Where the means of limiting

cargo tank overpressure includes an automatic closing valve,the valve shall comply with the appropriate provisions of15.19.

8.2.4 Tank venting systems shall be designed and op-erated so as to ensure that neither pressure nor vacuum createdin the cargo tanks during loading or unloading exceeds tankdesign parameters. The main factors to be considered in thesizing of a tank venting system are as follows:

.1 design loading and unloading rate;.

.2 gas evolution during loading: this shall betaken account of by multiplying the maximumloading rate by a factor of at least 1.25;

.3 density of the cargo vapour mixture;

.4 pressure loss in vent piping and across valvesand fittings; and

8.2.6 The master shall be provided with the maximumpermissible loading and unloading rates for each tank or groupof tanks consistent with the design of the venting systems.

8.2.7 Self-draining back to the cargo tanks shall be bynatural gravity.

When large amounts of drainage from vent linesis envisaged, provision for a hose connection to a drain linedraining to a suitable slop tank shall be provided.

8.2.8 The system which protects against the liquidlevel exceeding the design head of the cargo tank, referred toin 8.2.3, shall be independent of the cargo tank gauging de-vices.

8.2.9 When designing cargo tank venting arrange-ments revised factors contained in MSC/Circ.731 shall betaken into consideration.

8.2.10 High level alarms and overflow control systemsspecified in 8.2.3 shall be type approved by the Register.

8.3 TYPES OF TANK VENTINGSYSTEM

8.3.1 An open tank venting system is a system whichoffers no restriction except for friction losses to the free flowof cargo vapours to and from the cargo tanks during normaloperations. An open venting system may consist of individualvents from each tank, or such individual vents may be com-bined into a common header or headers, with due regard tocargo segregation. In no case shall shutoff valves be fitted ei-ther to the individual vents or to the header.

8.3.2 A controlled tank venting system is a system inwhich pressure- and vacuum-relief valves or pressure/vacuumvalves are fitted to each tank to limit the pressure or vacuumin the tank. A controlled venting system may consist of indi-vidual vents from each tank or such individual vents on thepressure side only as may be combined into a common headeror headers, with due regard to cargo segregation. In no caseshall shut-off valves be fitted either above or below pressure-or vacuum-relief valves or pressure /vacuum valves. Provision


2009

may be made for bypassing a pressure- or vacuum-relief valveor pressure/vacuum valve under certain operating conditionsprovided that the requirement of 8.3.6 is maintained and thatthere is suitable indication to show whether or not the valve isbypassed.

8.3.3 Controlled tank venting systems shall consist ofa primary and a secondary means of allowing full flow reliefof vapour to prevent over-pressure or under-pressure in theevent of failure of one means. Alternatively, the secondarymeans may consist of pressure sensors fitted in each tank witha monitoring system in the ship's cargo control room or posi-tion from which cargo operations are normally carried out.Such monitoring equipment shall also provide an alarm facil-ity which is activated by detection of over-pressure or under-pressure conditions within a tank.

8.3.4 The position of vent outlets of a controlled tankventing system shall be arranged:

.1 at a height of not less than 6 m above theweather deck or above a raised walkway iffitted within 4 m of the raised walkway;and

.2 at a distance of at least 10 m measuredhorizontally from the nearest air intake oropening to accommodation, service andmachinery spaces and ignition sources.

8.3.5 The vent outlet height referred to in 8.3.4.1 maybe reduced to 3 m above the deck or a raised walkway, as ap-plicable, provided that high-velocity venting valves of an ap-proved type, directing the vapour/air mixture upwards in anunimpeded jet with an exit velocity of at least 30 m/s, are fit-ted.

8.3.6 Controlled tank venting systems fitted to tanksto be used for cargoes having a flashpoint not exceeding 60°C(closed-cup test) shall be provided with devices to prevent thepassage of flame into the cargo tanks. The design, testing andlocating of the devices shall comply with the requirements ofthe Register, which shall contain at least the standards adoptedby the Organization.

8.3.7 In designing venting systems and in the selectionof devices to prevent the passage of flame for incorporationinto the tank venting system, due attention shall be paid to thepossibility of the blockage of these systems and fittings by, forexample, the freezing of cargo vapour, polymer build-up, at-mospheric dust or icing up in adverse weather conditions. Inthis context it shall be noted that flame arresters and flamescreens are more susceptible to blockage. Provisions shall bemade such that the system and fittings may be inspected, op-erationally checked, cleaned or renewed as applicable.

8.3.8 Reference in 8.3.1 and 8.3.2 to the use of shutoffvalves in the venting lines shall be interpreted to extend to allother means of stoppage, including spectacle blanks and blankflanges.

8.3.9 The term “with due regard to cargo segregation”referred to in 8.3.1 for open tank venting system means the de-sign that restricts the ingress of the cargo of a cargo tank intoother cargo tanks through vent lines even at times of heavyweather as given in Figure 8.3.9-1. In consideration of possi-ble degrading of product quality due to coming to contact withdifferent dangerous chemicals or their vapours, however, the

open type venting system shall be of independent design as faras practicable.

Figure 8.3.9-1Cargo segregation in open tank venting system

8.3.10 In case where the controlled venting systems ofthe cargo tanks carrying the cargoes different from each other,except those which react in a dangerous manner, or the samecargoes are led to a common pipe header, the pressure reliefvalves and vacuum regulating valves shall be separate fromeach other, and any other arrangement than that given in Fig-ure 8.3.10-1 is unacceptable. Vacuum regulating valves maybe of the arrangement either 1 or 2.

Figure 8.3.10-1Acceptable arrangements for the combined controlled tank

venting system

8.3.11 When pressure/vacuum valves, i.e. valves whosepressure side and vacuum side are led to the common pipe, areused for the controlled venting system of the cargo tanks in-tended to carry cargoes different from each other, any ar-rangement other than the venting system independent for eachtank or group of tanks, as applicable, is unacceptable.

8.3.12 As the countermeasures against the blockage by“freezing of cargo vapour or icing up in adverse weather con-ditions” referred to in 8.3.7, ships operated in cold zone shallbe provided with heating systems, etc. for the preventionthereof. In ships not provided with special heating systems,proper maintenance and inspection work procedures shall beestablished.

8.3.13 For a tank equipped with closed or restrictedgauging, the venting system shall be sized allowing for flamescreens, if fitted, to permit loading at the design rate withoutoverpressurizing the tank. Specifically, under conditions inwhich a saturated cargo vapour is discharged through theventing system at the maximum anticipated loading rate, thepressure differential between the cargo tank vapour space and


2009

the atmosphere shall not exceed 0.02 MPa or, for independentcargo tanks, the maximum working pressure of the tank.

8.3.14 Vent outlets of cargo tanks intended for the car-riage of flammable or toxic products shall be arranged at adistance of not less than 3 m from air outlets and as far as pos-sible from air inlets to pump rooms and cargo pump rooms.

8.3.15 Pressure relief valves and vacuum regulatingvalves (pressure/vacuum valves) shall be type approved by theRegister. The pressure setting, installation tests and markingshall comply with ISO standard 15364:2000 “Ships and ma-rine technology – Pressure/vacuum valves for cargo tanks”(see MSC/Circ.1009).

8.3.16 Devices to prevent the passage of flame (in-cluding high velocity valves) referred to in 8.3.6 shall be typeapproved by the Register.

The design, testing and locating shall complywith the MSC/Circ.677 – Revised standards for design, testingand locating of devices to prevent the passage of flame intocargo tanks in tankers.

8.4 VENTING REQUIREMENTS FORINDIVIDUAL PRODUCTS

8.4.1 Venting requirements for individual products areshown in column g, and additional requirements in column oin the table of Chapter 17.

8.5 CARGO TANK GAS-FREEING

8.5.1 The arrangements for gas-freeing of cargo tanksused for cargoes other than those for which open venting ispermitted shall be such as to minimize the hazards due to thedispersal of flammable or toxic vapours in the atmosphere andto flammable or toxic vapour mixtures in a cargo tank. Ac-cordingly, gas-freeing operations shall be carried out such thatvapour is initially discharged:

.1 through the vent outlets specified in 8.3.4and 8.3.5; or

.2 through outlets at least 2 m above thecargo tank deck level with a vertical exitvelocity of at least 30 m/s maintainedduring the gas-freeing operation; or

.3 through outlets at least 2 m above thecargo tank deck level with a vertical exitvelocity of at least 20 m/s which are pro-tected by suitable devices to prevent thepassage of flame.

When the flammable vapour concentration at theoutlets has been reduced to 30% of the lower flammable limitand, in the case of a toxic product, the vapour concentrationdoes not present a significant health hazard, gas-freeing maythereafter be continued at cargo tank deck level.

8.5.2 The outlets referred to in 8.5.1.2 and 8.5.1.3 maybe fixed or portable pipes.

8.5.3 In designing a gas-freeing system in conformitywith 8.5.1, particularly in order to achieve the required exitvelocities of 8.5.1.2 and 8.5.1.3, due consideration shall begiven to the following:

.1 materials of construction of system;

.2 time to gas-free;

.3 flow characteristics of fans to be used;

.4 the pressure losses created by ducting,piping, cargo tank inlets and outlets;

.5 the pressure achievable in the fan drivingmedium (e.g. water or compressed air);and .6 the densities of the cargo vapour/airmixtures for the range of cargoes to be car-ried.

8.5.4 When designing a gas-freeing system revisedfactors contained in MSC/Circ.731 shall be taken into consid-eration.

8.5.5 The method and instruction for cargo tank gas-freeing shall be described in the Cargo Operation Manual, indetail.

8.5.6 The outlets referred to in 8.5.1.2 and 8.5.1.3shall be arranged as far as practicable at distances specified in8.3.4 and 15.12, as applicable.

8.5.7 The fans used for cargo tank gas freeing, eitherfixed or partable type, located in hazardous locations shall beof nonsparking construction (see Rules, Part 9 – Machinery,5.3).

9 ENVIRONMENTALCONTROL

9.1 GENERAL

9.1.1 Vapour spaces within cargo tanks and, in somecases, spaces surrounding cargo tanks may require to havespecially controlled atmospheres.

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

.1 Inerting: by filling the cargo tank and associ-ated piping systems and, where specified inChapter 15, the spaces surrounding the cargotanks, with a gas or vapour which will notsupport combustion and which will not reactwith the cargo, and maintaining that condition.

.2 Padding: by filling the cargo tank and associ-ated piping systems with a liquid, gas or va-pour which separates the cargo from the air,and maintaining that condition.

.3 Drying: by filling the cargo tank and associ-ated piping systems with moisture-free gas orvapour with a dewpoint of -40°C or below atatmospheric pressure, and maintaining thatcondition.

.4 Ventilation: forced or natural.

15.5.3.1 Tanks having contained cargoes other than hy-drogen peroxide shall be inspected, cleaned and passivated be-fore re-use for the transport of hydrogen peroxide solutions.The procedures for inspection and cleaning, as given in para-graphs 15.5.3.2 to 15.5.3.8 below, apply to both stainless steeland pure aluminium tanks (see paragraph 15.5.2.2). Proce-dures for passivation are given in paragraph 15.5.3.9 forstainless steel and 15.5.3.10 for aluminium. Unless otherwisespecified, all steps apply to the tanks and to all associatedequipment having been in contact with the other cargo.

15.5.3.2 After unloading the previous cargo the tank shallbe rendered safe and inspected for any residues, scale and rust.

15.5.3.3 Tanks and associated equipment shall be washedwith clean filtered water. The water to be used shall at leasthave the quality of potable water with a low chlorine content.

15.5.3.4 Trace residues and vapours of the previous cargoshall be removed by steaming of tank and equipment.

15.5.3.5 Tank and equipment are washed again withclean water (quality as above) and dried, using filtered, oil-free air.

15.5.3.6 The atmosphere in the tank shall be sampled andinvestigated for the presence of organic vapours and oxygenconcentration.

15.5.3.7 The tank shall be checked again by visual in-spection for residues of the previous cargo, scale and rust aswell as for any smell of the previous cargo.

15.5.3.8 If inspection or measurements indicate the pres-ence of residues of the previous cargo or its vapours, actionsdescribed in paragraphs 15.5.3.3 to 15.5.3.5 shall be repeated.

15.5.3.9 Tank and equipment made from stainless steelwhich have contained other cargoes than hydrogen peroxide orwhich have been under repair shall be cleaned and passivated,regardless of any previous passivation, according to the fol-lowing procedure:


2009

.1 New welds and other repaired parts shallbe cleaned and finished using stainlesssteel wire brush, chisel, sandpaper or buff.Rough surfaces shall be given a smoothfinish. A final polishing is necessary.

.2 Fatty and oily residues shall be removedby the use of appropriate organic solventsor detergent solutions in water. The use ofchlorine-containing compounds shall beavoided as they can seriously interferewith passivation.

.3 The residues of the degreasing agent shallbe removed, followed by a washing withwater.

.4 In the next step, scale and rust shall be re-moved by the application of acid (e.g. amixture of nitric and hydrofluoric acids),followed again by a washing with cleanwater.

.5 All the metal surfaces which can come intocontact with hydrogen peroxide shall bepassivated by the application of nitric acidof a concentration between 10 and 35% bymass. The nitric acid must be free fromheavy metals, other oxidizing agents orhydrogen fluoride. The passivation processshall continue for 8 to 24 h, dependingupon the concentration of acid, the ambi-ent temperature and other factors. Duringthis time a continuous contact between thesurfaces to be passivated and the nitricacid shall be ensured. In the case of largesurfaces this may be achieved by recircu-lating the acid. Hydrogen gas may beevolved in the passivation process, leadingto the presence of an explosive atmospherein the tanks. Therefore, appropriate meas-ures must be taken to avoid the build-up orthe ignition of such an atmosphere.

.6 After passivation the surfaces shall bethoroughly washed with clean filtered wa-ter. The washing process shall be repeateduntil the effluent water has the same pHvalue as the incoming water.

.7 Surfaces treated according to the abovesteps may cause some decompositionwhen coming into contact with hydrogenperoxide for the first time. This decompo-sition will cease after a short time (usuallywithin two or three days). Therefore anadditional flushing with hydrogen perox-ide for a period of at least two days is rec-ommended.

.8 Only degreasing agents and acid cleaningagents which have been recommended forthis purpose by the manufacturer of thehydrogen peroxide shall be used in theprocess.

15.5.3.10 Tanks and equipment made from aluminium andwhich have contained cargoes other than hydrogen peroxide,or which have been under repair, shall be cleaned and passi-vated. The following is an example of a recommended proce-dure:

.1 The tank shall be washed with a solutionof a sulphonated detergent in hot water,followed by a washing with water.

.2 The surface shall then be treated for 15 to20 min with a solution of sodium hydrox-ide of a concentration of 7% by mass ortreated for a longer period with a less con-centrated solution (e.g. for 12 h with 0.4 to0.5% sodium hydroxide). To prevent ex-cessive corrosion at the bottom of the tankwhen treating with more concentrated so-lutions of sodium hydroxide, water shallbe added continuously to dilute the sodiumhydroxide solution which collects there.

.3 The tank shall be thoroughly washed withclean, filtered water. As soon as possibleafter washing, the surface shall be passi-vated by the application of nitric acid of aconcentration between 30 and 35% bymass. The passivation process shall con-tinue for 16 to 24 h. During this time acontinuous contact between the surfaces tobe passivated and the nitric acid shall beensured.

.4 After passivation the surfaces shall bethoroughly washed with clean, filteredwater. The washing process shall be re-peated until the effluent water has thesame pH value as the incoming water.

.5 A visual inspection shall be made to en-sure that all surfaces have been treated. Itis recommended that an additional flushingis carried out for a minimum of 24 h withdilute hydrogen peroxide solution of aconcentration approximately 3% by mass.

15.5.3.11 The concentration and stability of the hydrogenperoxide solution to be loaded shall be determined.

15.5.3.12 The hydrogen peroxide is loaded under inter-mittent visual supervision of the interior of the tank from anappropriate opening.

15.5.3.13 If substantial bubbling is observed which doesnot disappear within 15 min after the completion of loading,the contents of the tank shall be unloaded and disposed of inan environmentally safe manner. The tank and equipment shallthen be repassivated as described above.

15.5.3.14 The concentration and stability of the hydrogenperoxide solution shall be determined again. If the same val-ues are obtained within the limits of error as in paragraph15.5.2.10, the tank is considered to be properly passivated andthe cargo ready for shipment.

15.5.3.15 Actions described in paragraphs 15.5.3.2 to15.5.3.8 shall be carried out under the supervision of the mas-ter or shipper. Actions described in paragraphs 15.5.3.9 to15.5.3.15 shall be carried out under the on-site supervision andresponsibility of a representative of the hydrogen peroxidemanufacturer or under supervision and responsibility of an-other person familiar with the safety-relevant properties of hy-drogen peroxide.

15.5.3.16 The following procedure shall be applied whentanks having contained hydrogen peroxide solution are to beused for other products (unless otherwise specified, all steps


2009

apply to the tanks and to all associated equipment having beenin contact with hydrogen peroxide):

.1 Hydrogen peroxide cargo residue shall bedrained as completely as possible fromtanks and equipment.

.2 Tanks and equipment shall be rinsed withclean water, and subsequently thoroughlywashed with clean water.

.3 The interior of the tank shall be dried andinspected for any residues.

Steps .1 to .3, in 15.5.3.16, shall be carried outunder the supervision of the master or the shipper.

Step .3 in paragraph 15.5.3.16 shall be carriedout by a person familiar with the safety-relevant properties ofthe chemical to be transported and of hydrogen peroxide.

Special cautions

.2 Hydrogen gas may be evolved in the pas-sivation processes described in paragraphs15.5.3.9.5, 15.5.3.10.2 and 15.5.3.10.4,leading to the presence of an explosive at-mosphere in the tank. Therefore, appro-priate measures must be taken to avoid thebuild-up or the ignition of such an atmos-phere.

15.5.3.17 Hydrogen peroxide solutions shall be stabilizedto prevent decomposition. A certificate of stabilization shall beprovided by the manufacturer, and kept on board, specifying:

.1 name and amount of stabilizer added;

.2 date stabilizer was added and duration ofeffectiveness;

15.13 CARGOES PROTECTED BYADDITIVES

15.13.1 Certain cargoes with a reference in column o inthe table of Chapter 17, by the nature of their chemical make-up, tend, under certain conditions of temperature, exposure toair or contact with a catalyst, to undergo polymerization, de-composition, oxidation or other chemical changes. Mitigationof this tendency is carried out by introducing small amounts ofchemical additives into the liquid cargo or controlling thecargo tank environment.

15.13.2 Ships carrying these cargoes shall be so de-signed as to eliminate from the cargo tanks and cargo-handlingsystem any material of construction or contaminants whichcould act as a catalyst or destroy the inhibitor.

15.13.3 Care shall be taken to ensure that these cargoesare sufficiently protected to prevent deleterious chemicalchange at all times during the voyage. Ships carrying suchcargoes shall be provided with a certificate of protection fromthe manufacturer, and kept during the voyage, specifying:

.1 the name and amount of additive present;

.2 whether the additive is oxygen - depend-ent;

.3 date additive was put in the product andduration of effectiveness;

.4 any temperature limitations qualifying theadditives' effective lifetime; and

.5 the action to be taken shall the length ofvoyage exceed the effective lifetime of theadditives.

15.13.4 Ships using the exclusion of air as the method ofpreventing oxidation of the cargo shall comply with 9.1.3.

15.13.5 A product containing an oxygen-dependent ad-ditive shall be carried without inertion (in tanks of a size notgreater than 3,000 m3). Such cargoes shall not be carried in atank requiring inertion under the requirements of section 9.3For equivalency arrangements for the carriage of styrenemonomer, see MSC/Circ.879 and MSC/Circ.879/Corr.1.

15.13.6 Venting systems shall be of a design that elimi-nates blockage from polymer build-up. Venting equipmentshall be of a type that can be checked periodically for ade-quacy of operation

15.13.7 Crystallization or solidification of cargoes nor-mally carried in the molten state can lead to depletion of in-hibitor in parts of the tank's contents. Subsequent remeltingcan thus yield pockets of uninhibited liquid, with the accom-panying risk of dangerous polymerization. To prevent this,care shall be taken to ensure that at no time are such cargoesallowed to crystallize or solidify, either wholly or partially, inany part of the tank. Any required heating arrangements shallbe such as to ensure that in no part of the tank does cargo be-come overheated to such an extent that any dangerous polym-erization can be initiated. If the temperature from steam coilswould induce overheating, an indirect low-temperature heatingsystem shall be used.

17.3 NOTES TO THE TABLE 17.1.1-1

(a) If the product to be carried contains flamma-ble solvents such that the flashpoint does notexceed 60°C, then special electrical systemsand a flammable-vapour detector shall beprovided.

(b) Although water is suitable for extinguishingopen-air fires involving chemicals to whichthis footnote applies, water shall not be al-lowed to contaminate closed tanks containingthese chemicals because of the risk of haz-ardous gas generation.

(c) Phosphorus, yellow or white is carried aboveits autoignition temperature and thereforeflashpoint is not appropriate. Electricalequipment requirements may be similar tothose for substances with a flashpoint above60°C.

(d) Requirements are based on those isomershaving a flashpoint of 60°C, or less; someisomers have a flashpoint greater than 60°C,and therefore the requirements based onflammability would not apply to such iso-mers.

(e) Applies to n-decyl alcohol only.(f) Dry chemical shall not be used as fire extin-

guishing media.(g) Confined spaces shall be tested for both for-

mic acid vapours and carbon monoxide gas, adecomposition product.

(h) Applies to p-xylene only.(i) For mixtures containing no other components

with safety hazards and where the pollutioncategory is Y or less.

(j) Only certain alcohol-resistant foams are ef-fective.

(k) Requirements for Ship Type identified in col-umn e might be subject to regulation 4.1.3 ofAnnex II of MARPOL 73/78.

(l) Applicable when the melting point is equal toor greater than 0°C.

(m) From vegetable oils specified in Chapter 17.

18 LIST OF PRODUCTS TOWHICH THIS PART OF THERULES DOES NOT APPLY

18.1 GENERAL

18.1.1 The following are products (see Table18.1.1-1), which have been reviewed for their safety andpollution hazards and determined not to present hazards tosuch an extent as to warrant application of this Part of theRules.

18.1.2 Although the products listed in this chapter falloutside the scope of this Part of the Rules, the attention isdrawn to the fact that some safety precautions may be neededfor their safe transportation. Accordingly, the Register shallprescribe appropriate safety requirements (see column c).

18.1.3 Some liquid substances are identified as fallinginto Pollution Category Z and, therefore, subject to certainrequirements of Annex II of MARPOL 73/78.

18.1.4 Liquid mixtures which are assessed or provi-sionally assessed as prescribed in 6, Annex II, MARPOL73/78 as falling into Pollution Category Z or OS, and whichdo not present safety hazards, may be carried under the ap-propriate entry in this chapter for “Noxious or Non-NoxiousLiquid Substances, not otherwise specified (n.o.s.)“.

19 TRANSPORT OF LIQUIDCHEMICAL WASTES

19.1 PREAMBLE

19.1.1 Maritime transport of liquid chemical wastescould present a threat to human health and to the environ-ment.

19.1.2 Liquid chemical wastes shall, therefore, betransported in accordance with relevant international conven-tions and recommendations and, in particular, where it con-cerns maritime transport in bulk, with the requirements ofthis Part of the Rules.

19.2 DEFINITIONS

For the purpose of this chapter:

19.2.1 Liquid chemical wastes are substances, solu-tions or mixtures, offered for shipment, containing or con-taminated with one or more constituents which are subject tothe requirements of this Part of Rules and for which no directuse is envisaged but which are carried for dumping, incinera-tion or other methods of disposal other than at sea.

19.2.2 Transboundary movement means maritimetransport of wastes from an area under the national jurisdic-tion of one country to or through an area under the nationaljurisdiction of another country, or to or through an area notunder the national jurisdiction of any country, provided atleast two countries are concerned by the movement.

19.3 APPLICABILITY

19.3.1 The requirements of this chapter are applicableto the transboundary movement of liquid chemical wastes inbulk by seagoing ships and shall be considered in conjunctionwith all other requirements of this Part of the Rules.

19.3.2 The requirements of this chapter do not applyto:

.1 wastes derived from shipboard operationswhich are covered by the requirements ofMARPOL 73/78; and

19.5 DOCUMENTATION

19.5.1 In addition to the documentation specified in16.2 of this Part of the Rules, ships engaged in transboundarymovement of liquid chemical wastes shall carry on board awaste movement document issued by the competent authorityof the country of origin.

19.6 CLASSIFICATION OF LIQUIDCHEMICAL WASTES

19.6.1 For the purpose of the protection of the marineenvironment, all liquid chemical wastes transported in bulkshall be treated as Category X noxious liquid substances, ir-respective of the actual evaluated category.

19.7 CARRIAGE AND HANDLING OFLIQUID CHEMICAL WASTES

19.7.1 Liquid chemical wastes shall be carried in shipsand cargo tanks in accordance with the minimum require-ments for liquid chemical wastes specified in Chapter 17,unless there are clear grounds indicating that the hazards ofthe wastes would warrant:

.1 carriage in accordance with the ship type1 requirements; or

.2 any additional requirements of this Part ofthe Rules applicable to the substance or,in case the of a mixture, its constituentpresenting the predominant hazard.
