摘　　要：大型半潜式平台船体分段结构形式复杂、重量大、吊装高度高、吊装难度大。船体传统合拢方式需要在船坞建造,使用龙门吊进行船体的吊装合拢作业,本文将结合“深海一号”半潜式平台项目建造施工实践,详细阐述在不占用船坞资源和不使用龙门吊的条件下,通过特制的吊排系统,利用大型履带吊实现大型半潜式平台船体在滑道合拢集成。可为相关项目提供工艺参考。It is difficult to lift the hull section structure of large semi-submersible platforms because of its structure,weight,and lifting height.Traditionally,the integration has to be conducted in the dock,and the gantry crane has to be used.This paper,in combination with the construction of "Deep Sea No.1" semi-submersible platform,expounds in detail the integration of the semi-submersible platform without using the dock and the gantry crane,by just using the lifting row system and large crawler crane.
