本欧洲标准给出了用于海上输送的液化天然气（LNG）输送软管的设计、材料选择、鉴定、认证和试验细节的一般指南，或用于高空、浮式和水下配置的沿海暴露设施或这些结构的组合。虽然本欧洲标准适用于所有液化天然气软管，但公认的是，对于浮式和水下式软管，可能还有进一步的具体要求。 输送软管将设计为输送系统的一部分（这意味着它们将配备ERS、QCDC、装卸系统、液压和电气部件等），以避免不必要的重复，交叉引用EN 1474-1和EN 1474-3适用于所有兼容项目、参考文献、定义和缩写。如果液化天然气软管特别需要额外的参考文献、定义和缩写，则在本欧洲标准中列出。 在海洋环境中操作时，输送软管必须耐用，并且具有与搬运和输送系统操作要求兼容的最小弯曲半径的柔性。

This European Standard gives general guidelines for the design, material selection, qualification, certification, and testing details for Liquefied Natural Gas (LNG) transfer hoses for offshore transfer or on coastal weather-exposed facilities for aerial, floating and submerged configurations or a combination of these. Whilst this European Standard is applicable to all LNG hoses, it is acknowledged that there may be further specific requirements for floating and submerged hoses. The transfer hoses will be designed to be part of transfer systems (it means that they will be fitted with ERS, QCDC, handling systems, hydraulic and electric components etc.) To avoid unnecessary repetition, cross-references to EN 1474-1 and EN 1474-3, are made for all compatible items, and for references, definitions and abbreviations. Where additional references, definitions and abbreviations are required specifically for LNG hoses, they are listed in this European Standard. Transfer hoses need to be durable when operating in the marine environment and to be flexible with a minimum bending radius compatible with handling and the operating requirements of the transfer system.
