BS EN 1474-2 discusses about Installation and equipment for liquefied natural gas.
BS EN 1474-2 gives general guidelines for the design, material selection, qualification, certification, and testing details of hose assemblies for Liquefied Natural Gas (LNG) marine transfer applications.
The transfer hose assemblies are part of transfer systems (it means that they may be fitted with ERS, QCDC, handling systems, hydraulic and electric components, etc.)
BS EN 1474-2 on design and testing of transfer hoses is beneficial for:
Transfer hose is a rugged suction and discharge, flexible hose designed for oilfield applications. The hose is designed to handle the transfer of salt and fresh water.
BS EN 1474-2 assists the user with various types of transfer hoses. A corrugated metal hose assembly consists of a core layer made of stainless-steel corrugations, and several other layers, metallic or non-metallic, reinforcing the mechanical strength of the flexible part of the hose assembly. A composite hose assembly consists of un-bonded, multiple polymeric films and fabric layers bounded between two-wire helices which give the flexible part of the hose assembly its shape, one being internal and one being external.
An LNG Transfer Hose assembly consists of the following:
At present LNG transfer hose assemblies are categorized in three types according to their method of construction:
Overall, BS EN 1474-2 is helpful as it aids in the hose assembly forms which is part of a system for the transfer of LNG, for the requirements which dictate the exact design of the hose assembly. The hose assembly construction ensures that all materials are used within their individual range of temperature.
BS EN 1474-2:2020 supersedes BS EN 1474‑2:2008, which is withdrawn.
In comparison with the previous edition, the following technical modifications have been made:
