International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electro

The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of

19、ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives). Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held

23、properties, characteristics, and behaviour of LNG differ significantly from conventional marine fuels, such as heavy fuel oils and distillate fuels as marine diesel oil (MDO) or marine gas oil (MGO). For these reasons, it is essential that all LNG bunkering operations are undertaken with diligence a

24、nd due attention is paid to prevent leakage of LNG liquid or vapour and to control all sources of ignition. Therefore, it is necessary that throughout the LNG bunkering chain, each element is carefully designed and has dedicated safety and operational procedures executed by trained personnel. It is

25、important that the basic requirements laid down in this Technical Specification are understood and applied to each operation in order to ensure the safe, secure, and efficient transfer of LNG as a fuel to the ship. The objective of this Technical Specification is to provide guidance for the planning

26、 and design of the following and thereby ensuring that an LNG fuelled ship can refuel with a high level of safety, integrity, and reliability regardless of the type of bunkering facility: bunkering facility; ship/bunkering facility interface; procedures for connection and disconnection; monitoring p

27、rocedures during bunkering; emergency shutdown interface; LNG bunkering process control. The LNG bunkering interface comprises the area of LNG transfer and includes manifold, valves, safety and security systems and other equipment, and the personnel involved in the LNG bunkering operations. This Tec

28、hnical Specification is based on the assumption that the receiving ships and LNG supply facilities are designed according to the relevant and applicable codes, regulations, and guidelines such as the International Maritime Organization (IMO), ISO, EN, and NFPA standards and the Society of Internatio

29、nal Gas Tankers and Terminal Operators (SIGTTO), the Oil Companies International Marine Forum (OCIMF), and other recognized documents during LNG bunkering. Relevant publications by these and other organizations are listed in the Bibliography. It has to be recognized that in cases where the distance

30、to third parties is too close and the risk exceeds acceptance criteria, the bunkering location is not to be considered. It is not necessary that the provisions of this Technical Specification are applied retroactively. It is recognized that national/local laws and regulations take precedence when th

31、ey are in conflict with this Technical Specification.vi ISO 2015 All rights reservedPD ISO/TS 18683:2015Guidelines for systems and installations for supply of LNG as fuel to ships 1 Scope This Technical Specification gives guidance on the minimum requirements for the design and operation of the LNG

32、bunkering facility, including the interface between the LNG supply facilities and receiving ship as shown in Figure 1. This Technical Specification provides requirements and recommendations for operator and crew competency training, for the roles and responsibilities of the ship crew and bunkering p

33、ersonnel during LNG bunkering operations, and the functional requirements for equipment necessary to ensure safe LNG bunkering operations of LNG fuelled ships. This Technical Specification is applicable to bunkering of both seagoing and inland trading vessels. It covers LNG bunkering from shore or s

34、hip LNG supply facilities, as shown in Figure 1 and described in Clause 4, and addresses all operations required such as inerting, gassing up, cooling down, and loading.
