摘要:

目前海底输送原油管线基本采用双层保温结构.分析了双层保温海管设计中锚固件及阻水器的设计原则.介绍了锚固件及阻水器的结构形式,安装方式以及对海管力学性能的影响,并作了经济性比较.最后,对锚固件及阻水器各自的优缺点进行比较分析,给出设计中选用锚固件或阻水器的数量和结构形式的原则.结合陆丰13-2海管更换项目的应用情况,对分析结论进行了验证.

关键词: 海底管线, 锚固件, 阻水器, 保温失效长度

Abstract:

The pipe-in-pipe (PIP) insulation pipeline configuration has been widely used in crude oil transportation. We analyze the selection principles of bulkhead and water stop in PIP insulation pipeline design. The structure configuration, installation method, mechanical property and economy are compared between the bulkhead and water stop. Their advantages and disadvantages are given. The selection principles for number and configuration of the bulkheads and water stops are described. Finally, the conclusion is verified in the LF13-2 pipeline replacement project.

Key words: marine pipeline, anchor, water stop, insulation failure length
