海底管道拖拉封头设计

Design of Offshore Pipeline Towing Head

通过对常规海管铺设过程的分析,归纳总结了三种常用的海管拖拉封头结构型式,并针对其结构设计,应用理论和有限元模拟相结合的方法进行了强度校核,结果表明,该拖拉封头的结构设计能够满足常规海管铺设过程的需求.

Through an analysis of conventional offshore pipe laying, three structural styles commonly used for the pipeline head are summarized. Strength of the design pipeline head is checked by using the theoretical formula and finite element simulation respectively. It is shown that the structural design for the pipeline head can meet the demand of pipe laying.
