Significance and Use4.1 This guide is intended to define and identify bestpractices for minimum requirements for the design,installation, and application of Type C portable tanks formarine service on LN

17、G fueled vessels for service as a LNGfuel tank. These best practices provide added detail to therequirements in 6.5 of the IGF Code to facilitate consistent andpractical implementation of those requirements.5. ProcedureNOTE 1In addition to the regulations in 6.5 of the IGF Code, thefollowing represe

18、nt best practices for the safe design, installation, andoperation of Type C portable tanks for use in shipboard LNG fuel systems.The following text in italics comes from the International Code of Safetyfor Ships using Gases or other Low-Flashpoint Fuels (IGF Code).5.1 Tank ConstructionThe design of

19、the tank shall complywith IGF Code 6.4.15.3. The tank support (container frame ortruck chassis) shall be designed for the intended purpose (IGFCode 6.5.1).5.1.1 The design of the tank support shall include consid-erations to withstand green seas if applicable for the operatingenvironment.5.1.2 The d

20、eck strength calculation shall be included and bepart of the design approval process.5.1.3 The portable tank connections shall be clearly colormarked and labelled to indicate its function in accordance withISO 14726.5.1.4 Plan review and approval of portable tanks shall bevessel-specific with docume

21、ntation clearly indicating the ves-sel or vessels for which the tanks have been designed. Eachportable tank approved for use with a vessels LNG fuel systemshall be listed in the vessels fuel handling manual (IGF Code18.2.3) by serial number or other suitable identifying marking.Due consideration sha

22、ll be given to applicable internationaland domestic multi-modal portable tank regulations such asthose contained in the IMO IMDG Code.5.2 Tank LocationPortable fuel tanks shall be located indedicated areas fitted with (IGF Code 6.5.2) the following:5.2.1 Mechanical protection of the tanks depending

23、onlocation and cargo operations (IGF Code 6.5.2.1). Mechanicalprotection shall be in the form of a structural frame around thetank in accordance with ISO 1496-3 or equivalent. The riskassessment required by 4.2 and 6.4.1.1 of the IGF Code shouldaddress any mechanical protection required for portable

24、 fueltanks taking into account the tanks location, the overall vesseldesign, and the cargo/vessel operations. This includes protec-tion against the following:5.2.1.1 Lateral impact, which may consist of longitudinalbars protecting the shell on both sides;5.2.1.2 Overturning, which may consist of rei

25、nforcementrings or bars fixed across frames;5.2.1.3 Front and rear impact, which may consist of abumper or frame; and5.2.1.4 Shell damage, which may consist of a structuralframe constructed in accordance with a recognized standard.5.2.2 If located on open deck: spill protection and waterspray system

26、s for cooling (IGF Code 6.5.2.2).5.2.2.1 Spill protection can either be part of the tank framesupport or the ship. If it is part of the portable tank, it shall beconnected by flexible hose to the ships system in accordanceto EN 1474-2: or equivalent.5.2.2.2 Similarly, the water spray system can be p

27、art of theportable tank or the ship.5.3 Tank-Securing SystemsPortable fuel tanks shall besecured to the deck while connected to the ship systems. Thearrangement for supporting and fixing the tanks shall bedesigned for the maximum expected static and dynamicinclinations, as well as the maximum expect

28、ed values ofacceleration, taking into account the ship characteristics andthe position of the tanks (IGF Code 6.5.3).5.3.1 The design of the supporting and fixing arrangementshall include external forces such as green seas, as applicableto the operating environment.5.3.2 If the fuel tank is mounted

29、on a truck chassis, thesecuring system shall be such that the weight of the tank shallnot be carried by the truck wheels and tires, which may besubject to punctures or completely damaged in a fire scenario.5.3.3 Securing arrangements are to be included in the fuelhandling manual (IGF Code 18.2.3).5.

30、3.4 Recognized standard is 49 CFR 393.134 or equivalent.5.4 Tank Consideration on Vessel Strength and StabilityConsideration shall be given to the strength and the effect ofthe portable fuel tanks on the ships stability (IGF Code 6.5.4).5.5 Connections to Ships Fuel Piping SystemsConnections to the

31、ships fuel piping systems shall be made bymeans of approved flexible hoses or other suitable meansdesigned to provide suffcient flexibility (IGF Code 6.5.5).5.5.1 Connections and piping shall be so positioned andarranged that any damage to the fuel piping does not causedamage to the ships fuel conta

32、inment system resulting in anuncontrolled gas discharge.5.5.2 Hoses subject to tank pressure, shall be designed for abursting pressure not less than five times the maximumpressure the hose can be subjected to.5.5.3 The surrounding hull or deck structures shall not beexposed to unacceptable cooling,

33、in case of leakage of fuel.The flexible hose and connections shall have spill protection orshielding around it.5.5.4 An arrangement for purging fuel lines with inert gasshall be provided for the exchange of portable fuel tanks.5.5.5 Each ships fuel piping system connection shall becolor marked and l

34、abelled to indicate its function in accordancewith ISO 14726.5.5.6 Procedure for connecting shall be included in thevessels fuel handling manual (IGF Code 18.2.3).5.6 Spill LimitationArrangements shall be provided tolimit the quantity of fuel spilled in case of inadvertentdisconnection or rupture of

35、 the non-permanent connections(IGF Code 6.5.6).F3285 1825.6.1 Drip trays are to be evaluated by risk assessment as inaccordance with IGF Code 5.10.5.5.6.2 The portable fuel tank and ships fixed fuel supplysystem are to be evaluated by risk assessment for automaticisolation to meet the functional req

36、uirements of IGF Code15.2.2.5.6.3 Risk assessment shall determine the need for drybreak-away coupling/ self-sealing quick release of the portablefuel tank and fixed fuel supply system. The couplings wherefitted shall be of a standard type.5.7 Pressure Relief SystemThe pressure relief system ofportab

37、le tanks shall be connected to a fixed venting system(IGF Code 6.5.7). Connections to the ships fixed ventingsystem shall be made by means of approved flexible hoses orother suitable means designed to provide sufficient flexibility.Standard of hoses shall be in accordance to EN 1474-2: orequivalent.
