1.1 本规程涵盖了与液化天然气（LNG）燃料船舶加注相关的低温服务燃料舱软管输送组件的设计、制造和部署的最低要求。本规程所述的燃料舱软管输送组件用于液化天然气燃料船燃料舱歧管展示法兰连接和液化天然气供应商燃料舱歧管展现法兰连接之间的连接。 1.2 转换组件适用于多种海上加油应用，包括但不限于设施、船舶、卡车和其他液化天然气加油供应服务。 本规程将直接涉及软管组件、干式快速断开联轴器（DQD）、分离式联轴器、垫圈、绝缘法兰、过滤器和相关配件。 1.3 以国际单位制或英寸磅单位表示的数值应单独视为标准。每个系统中规定的值不一定是完全相等的；因此，为了确保符合标准，每个系统应独立使用，并且不得将两个系统的值组合使用。 1.4 本标准并不旨在解决与其使用相关的所有安全问题（如有）。 本标准的使用者有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.5 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。 ====意义和用途====== 4.1 本规程提供了与液化天然气燃料船加注相关的低温服务燃料舱软管输送组件的设计、制造、安装和操作的最低要求指南。本规程所述的燃料舱软管输送组件用于液化天然气燃料船燃料舱歧管展示法兰连接和液化天然气供应商燃料舱歧管展现法兰连接之间的连接。

1.1 This practice covers the minimum requirements for the design, manufacturing, and deployment of bunker hose transfer assemblies for cryogenic service pertaining to bunkering of liquefied natural gas (LNG)-fueled vessels. The bunker hose transfer assemblies addressed by this practice are for connections between the LNG-fueled vessel bunker manifold presentation flange connections and the LNG supplier bunkering manifold presentation flange connections. 1.2 Transfer assemblies are suitable for use in multiple maritime bunkering applications, including but not limited to facilities, vessels, trucks, and other LNG bunkering supply services. This practice will directly address the hose assembly, dry quick disconnect couplings (DQD), breakaway couplings, gaskets, insulating flange, strainers, and associated fittings. 1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined. 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 4.1 This practice provides guidance on the minimum requirements for the design, manufacture, installation, and operation of bunker hose transfer assemblies for cryogenic service pertaining to bunkering of LNG-fueled vessels. The bunker hose transfer assemblies addressed by this practice are for connections between the LNG-fueled vessel bunker manifold presentation flange connections and the LNG supplier bunkering manifold presentation flange connections.
