摘要
针对渤海FPSO气滑环传统更换作业中存在的管理界面多、动复员时间长、费用高昂、施工条件苛刻等问题,在传统更换方案基础上利用液压顶升装置建立液压临时闭环,改进气滑环密封更换及安装过程中吊装、拆卸、安装、调试等工序,现场应用表明,改进后的施工方案可缩短更换作业时间,降低整体工程费用投入,解决传统施工高投入、低实效等问题。
In view of the traditional replacement operation of the Bohai FPSO air slip ring,there are problems such as multiple management interfaces,long mobilization and demobilization time,high cost,and harsh construction conditions.Based on the traditional replacement scheme,the hydraulic jacking device was used to establish a temporary hydraulic closed loop,and the air slip ring seal replacement and installation processes of lifting,disassembly,installation,debugging and other procedures were improved.The field application indicated that the improved construction plan can shorten the replacement operation time,reduce the overall project cost investment and solve the problems of high investment and low efficiency in the traditional construction process.
