摘　　要：作为国内最大的海洋平台,荔湾3-1 CEP组块涉及较多厚壁结构的焊接,如何控制厚板焊接产生的变形是一个重要环节。此外,由于荔湾3-1 CEP组块特殊的建造工艺,建造过程中的重量转移对地基沉降及尺寸控制也有较高要求。从以上两点出发,分析研究了焊接变形的预防措施,并设计出特定工装,满足组块下放过程对尺寸的严格要求。As the biggest offshore platform in China,a lot of thick plates’welding are involved in fabrication of LW3-1 CEP topside,it’s an important part to control the deformation of the thick plates during welding.Besides,LW3-1 CEP topside is constructed with a special process,foundation settlement dimension should be also strictly controlled during the fabrication.Deformation precautions are researched in this article on the basis of above-mentioned aspects,a special tooling is designed to satisfy the dimension demand during load transference.
