Defines guidance on the minimum requirements for the design and operation of the LNG bunkering facility, including the interface between the LNG supply facilities and receiving ship.

This Technical Specification gives guidance on the minimum requirements for the design and operation of the LNG bunkering facility, including the interface between the LNG supply facilities and receiving ship as shown in Figure1. This Technical Specification provides requirements and recommendations for operator and crew competency training, for the roles and responsibilities of the ship crew and bunkering personnel 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 ship LNG supply facilities, as shown in Figure 1 and described in Clause4, and addresses all operations required such as inerting, gassing up, cooling down, and loading. Figure1 Interfaces between bunkering facility and supply/receiving facilities The use of portable storage tanks such as containers, trailers, or similar to load and store LNG on board ships to be used as fuel is not part of this Technical Specification.
