摘要:

主要对深水海管止屈器管的设计方法进行研究,并给出了止屈器管间距设计方法.止屈器管设计主要包括壁厚及间距的设计,其中止屈器管壁厚的设计主要依据解析公式及规范要求,而间距的设计在规范中并未明确说明.基于管材采办及施工的经济性与风险评估,介绍了一种用于计算间距的方法,并结合流花项目海管的应用情况对止屈器管的设计进行了验证.

关键词: 深水海管, 止屈器管, 扩展屈曲, 间距设计

Abstract:

In this paper, we mainly study the deepwater subsea pipeline arrestor design, and give the space calculation method for arrestors. The arrestor design includes wall thickness calculation and layout space calculation. The wall thickness design always follows the method given by the Det Norske Veritas (DNV) standard. However, there is no specific method for the space calculation in standards. Based on the analysis on pipe procurement and installation economical efficiency and risk assessment, we give a method for space calculation. This method has been successfully used in Liuhua pipeline project.

Key words: deepwater subsea pipeline, pipeline arrestor, propagation buckling, space design
