- 为解决大型导管架水下吊点方案吊点结构设计困难、液压卡环费用高以及导管架吊装实施技术风险大等问题,提出了一种吊装框架结构方案。对吊装框架结构方案的设计、建造及海上安装流程进行了阐述，基于SACS软件及ANSYS分析软件,对吊装框架主结构及吊点结构进行了强度分析和校核,验证了吊装框架结构方案的可行性,并总结了吊装框架结构设计特点和要点。分析结果显示,吊装框架结构方案,适用于大型导管架的海上吊装,可供同类项目的设计、建造和海上安装阶段参考。
A lifting frame structure design scheme is introduced in this paper to solve the difficulties in the design of lifting point for large offshore structure, the high procurement cost of the hydraulic clasp, and the high risk of jacket lifting implementation. The structural design plan, construction, and offshore installation process and key points of the lifting frame are elaborated in this paper. Based on SACS and ANSYS analytical software, the strength analysis and code verification on the main structure and trunnion of the lifting frame are carried out, the feasibility of the lifting frame structural design scheme is verified and the key structural design features and main points are summarized. According to the analysis result, it is shown that the lifting frame is suitable for offshore lifting of large jackets. These results can be used as a reference for the design, fabrication and offshore installation of future large offshore jacket projects of the same nature.
