ISO/TS 18683:2015给出了液化天然气加注设施设计和运行的最低要求指南，包括图1所示的液化天然气供应设施和接收船之间的接口。 ISO/TS 18683:2015提供了操作员和船员能力培训的要求和建议，以及LNG加注操作期间船员和加注人员的角色和责任，以及确保LNG燃料船舶安全加注LNG所需设备的功能要求。 ISO/TS 18683:2015适用于海船和内河商船的加注。它包括从岸上或船上液化天然气供应设施加注液化天然气，如图1所示和第4条所述，并说明了所需的所有操作，如惰化、加气、冷却和装载。

ISO/TS 18683:2015 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 Figure 1. ISO/TS 18683:2015 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. ISO/TS 18683:2015 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 Clause 4, and addresses all operations required such as inerting, gassing up, cooling down, and loading.
