针对水下生产系统跨接管在陆地建造过程中的吊装作业难点，着重分析如何降低大跨度柔性细长杆件跨接管吊装作业过程中的变形，以及降低吊装过程中吊机起吊高度等，提出使用多挡绳柱吊装撑杆并采用4点起吊的措施。应用 SACS 软件对跨接管吊装进行模拟计算，确定跨接管和撑杆总成的质量、重心，并由此确定吊钩、撑杆与跨接管之间的钢丝绳布置。根据计算结果中的吊绳力确定钢丝绳的规格，最终得出吊装过程中跨接管和撑杆的应力和变形情况。分析结果对后续水下生产系统跨接管、膨胀弯等细长管系结构吊装有一定的借鉴意义。

Absttact:The lifting difficulties during the fabrication for jumper of subsea production system (sps)were studied.It was emphatically analyzed that how to reduce the deformation of the large span flexible slender members during the lifting operation,and that how to lower the lifting height of the crane during lifting.The spreader bar with multiple pipe trunnion and four points lifting solution were put forward.SACS software was used to simulate the lifting process of the jumper,and to determine the weight and center of gravity of the jumper and spreader bar assem-bly.The arrangement of steel wire rope between crane hook,spreader bar and jumper was deter-mined,the specifications of the steel wire rope was also determined by the sling force calculated.Finally,the stress and deformation of the jumper and spreader bar during the lifting process was obtained.The result of the analysis has certain reference value for lifting similar subsea produc-tion system like jumper,spool etc.
