ISO 16904:2016规定了液化天然气（LNG）海上运输臂的设计、最低安全要求以及检查和测试程序，该运输臂拟用于常规陆上LNG接收站，用于处理从事国际贸易的LNG运输船。它可以为海上和沿海作业提供指导。它还涵盖了船岸之间安全输送液化天然气的最低要求。 尽管涵盖了动力/控制系统的要求，但本国际标准不包括与转移臂相关的标准零件和配件的设计和制造的所有细节。 ISO 16904:2016是对地方或国家标准和法规的补充，是对ISO 28460要求的补充。 ISO 16904:2016无需适用于现有设施。

ISO 16904:2016 specifies the design, minimum safety requirements and inspection and testing procedures for liquefied natural gas (LNG) marine transfer arms intended for use on conventional onshore LNG terminals, handling LNG carriers engaged in international trade. It can provide guidance for offshore and coastal operations. It also covers the minimum requirements for safe LNG transfer between ship and shore. Although the requirements for power/control systems are covered, this International Standard does not include all the details for the design and fabrication of standard parts and fittings associated with transfer arms. ISO 16904:2016 is supplementary to local or national standards and regulations and is additional to the requirements of ISO 28460. ISO 16904:2016 needs not be applied to existing facilities.
