浮式生产储卸油装置（FPSO）在海洋油气资源开发中起到了不可替代的作用，管廊模块是FPSO各个上部模块连接的中间枢纽，按照常规做法需要分层预制才能保证运输和吊装强度，分层预制后需要多次合拢对接，吊装时产生的柔性变形使得对接精度控制难度较大。基于某大型FPSO建造项目，提出一种管廊模块的甲板片一体化吊装工艺，使用SACS软件对管廊甲板片在翻身吊装作业的各个阶段做出理论强度校核计算，确保管廊甲板片整体预制和吊装作业的安全性及可靠性，有效节约了预制、喷涂、吊装等阶段使用的各类资源，解决了常规做法中H型钢总装组对精度控制的难题，降本增效效益明显，应用前景广阔。
FPSO (Floating Production Storage and Offloading) plays an irreplaceable role in the development of offshore oil and gas resources. The pipe rack module is the intermediate hub connecting each upper module of FPSO. According to the conventional practice, it needs to be prefabricated on layers to ensure the strength of transportation and lifting, which needs to be closed several times after stratified prefabrication, and the flexible deformation generated during lifting makes it difficult to control the docking accuracy. Introduces an integrated lifting process of deck pieces of pipe rack module. The theoretical strength of deck pieces of pipe rack in each stage of the lifting operation is checked by SACS software. It ensure the safety and reliability of the whole prefabrication,spraying lifting and other stages, avoids the difficulty of precision control of the conventional H-beam assembly group, reduces the cost and increases the efficiency, and has a broad application prospect.
