This part of EN 1474 gives general guidelines for the design, material selection, qualification, certification, and testing details for Liquefied Natural Gas (LNG) transfer hose for offshore transfer or on coastal weather- exposed facilities. To avoid unnecessary repetition, cross-reference to EN 1474-1 Design and Testing of Transfer Arms, is 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 part. For details of specific LNG transfer system architectures reference should be made to EN 1474-3. Hoses used for LNG transfer are normally large bore: typically from DN 250 (10") to above DN 400 (16") and more, with working design pressures in the range of 10 bar to 20 bar in order to meet the minimum flow rate from the facility of 10 000 m3/hour with a practical number of hoses used for LNG transfer and vapour return. Transfer hoses have 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.
