针对典型海域目标深水海底管道,基于J型铺设方案,采用有限单元模型,开展深水海底管道J型铺设的初步动态铺设分析,校核最大冯米赛斯应力满足许用要求、最大动态顶部张力在现有深水铺管船能力范围内。
Based on the J-laying scheme and the finite element model, a preliminary dynamic paving analysis of J-type deep-sea submarine pipeline is carried out. The maximum von Mises stress can meet the allowable requirements. The maximum dynamic top tension is between Existing deepwater pipelayers within the capabilities.
