简介:在海洋动态情况下,LNG的装载需要一种新型的柔性管线设备,该设备目前已经由法国Technip公司设计出来,该管线耐低温,能够防泄漏。管壁由三层特殊设计层组成。

LNG transfer in dynamic offshore conditions has required the development and qualification of a new technology related directly to heavy duty cryogenic flexible pipe systems.

The flexible pipe, designed by Technip France, as the key component of the Amplitude-LNG Loading System (ALLS), opens up new methods for the transfer of LNG in offshore and nearshore marine conditions. The ALLS operability was demonstrated and qualified in February 2008, at which time it was made fully available to the Industry. 

The cryogenic flexible is based on an internal stainless steel flexible bellows which ensures leak-proofness and compatibility with LNG. An insulation layer ensures the external face of the flexible has no ice build up during LNG transfer. An intermediate layer prevents ingress of humidity and provides a double annulus for instrumentation and leak detection purposes while an external leakproof layer renders the assembly water tight. 

The cryogenic flexible pipe was manufactured by Technip's manufacturing division, FlexiFrance, and system operability qualified by DNV. The ALLS also includes an automatic connection system, designed and manufactured by KSB & Eurodim. The complete system was qualified through a comprehensive test programme featuring dynamic testing and operated by GdFSuez Operators with live LNG from an LNG carrier.
