Abstract: The feasibility of offshore tandem lifting test for the semi-submersible lifting and disassembling unit has been discussed based on the procedure of the offshore tandem lifting with a 2 000 t crane, combining with the performance properties of the crane and the actual experiment environment. The operation of each segment in the procedure of the tandem lifting can be safe and reliable according to the characteristics of the unit. It can provide a theoretical basis for the later offshore tandem lifting test of the semi-submersible lifting and disassembling unit. The analysis results show that the tandem lifting procedures that meet the requirements of feasibility and safety can be tested at sea.

Key words: semi-submersible lifting and disassembling unit, quick ballast, tandem lift

摘要： 以配置2 200 t吊机的双机联吊作业过程为研究对象,结合吊机的性能参数和实际的试验环境探讨半潜起重拆解平台在海上双机联吊试验的可行性,根据平台系统的特性,联吊过程中各个环节的操作安全可行性,为后期半潜起重拆解平台在海上进行双机联吊试验提供理论基础。分析结果表明：联吊过程符合可行性与安全性要求,可以在海上进行试验。
