摘要
吊装作业在海洋石油平台结构物吊装及海上安装作业中占有非常重要的地位,一旦发生事故导致结构损伤或者作业失败,将造成生命财产的严重损失。吊点虽然是吊装作业的辅助结构,却需要承受吊装结构物自重以及其他附加载荷。因此,要充分保证海洋石油平台吊装的安全性,就必须考虑海洋石油平台吊点的焊接质量问题。结合近年参建的海油工程项目,介绍了海洋石油平台吊点的典型形式,从吊点常用钢及焊接性、焊接工艺设计以及焊接施工措施角度分析了海洋石油平台吊点的焊接施工技术。
Lifting operation plays an important role in the structure assembly and offshore installation of offshore oil platform. Once an accident causes structural damage or operation failure,it will cause serious loss of life and property. Although the hanging point is the auxiliary structure of lifting operation,it needs to bear the self-weight of the lifting structure and other additional loads. Therefore,in order to ensure the safety of offshore oil platform lifting,it is necessary to consider the welding quality of hanging points. Combining with management experience in many offshore oil platform engineering projects in resent years, the typical form of offshore oil platform is introduced, and the welding construction technique of hanging points in offshore oil platform is analyzed form the aspects of common steel and weldability,welding technology design and welding construction measures.
