摘要
对自升式钻井平台主弦管对接工艺及其齿条板接长工艺进行了研究,并结合齿条板材料特性提出了齿条板焊接技术及焊接施工要求,进而制定了主弦管对接工艺顺序及相关工艺技术要求。
The paper makes study on chord＇s butt joint technology and rack＇s lengthening technique of jack-up drilling unit. Combining with rack＇s material characteristics, rack＇s welding technique and welding procedure are proposed. And further, some rules of chord＇s butt joint sequence and relatively technologies are made.
