摘要 通过研究浅海海域特殊工况下铺管船锚泊分析和铺管分析方法和施工方案,以及大口径、较深水海底管道水平口对接提升下放的力学分析方法,建立了多船舶、多吊点动态联合作业的施工工艺,解决了狭窄航道半封航施工、低曲率半径弹性敷设、海底管道并行安全施工和大口径、大水深区海管水平口对接等技术难题,形成了复杂海域特殊工况下海底管道设计与施工的特色技术。 By studying the pipe laying ship mooring under the shallow sea area special working condition, the pipe-laying analysis method and the construction scheme, the mechanics analysis methnd of the large diameter, and the larger depth su|)sea pipeline level hull joint lifting and (Iropping, the dynamic joint operation of the construction technology of many ships and many hoist points is established. The technological problems in pipeline construction through narrow channel under a half closure navigation, the elastic laying lower curvature radius, the operation along with high pressure pipeline, and level butt joint under large-deep water area are solved. The featured technology of the subsea pipeline design and construction under special working condition in complex sea area is formed.
