摘要
以FPSO后舱IGG冷却海水泵的维修和前舱大型海水提升泵的吊装为例,阐述海洋石油平台海水泵维修所解决的两方面问题:①解决IGG冷却水泵故障频发问题,从泵的拆解状况、零部件数据测量、现场检修、工艺流程等多方面逐一分析导致泵气蚀和轴承高温的原因,对同类泵的故障排查有借鉴和推广作用;②解决大型泵在舱底限制空间内的吊装问题,自行设计加工海水提升泵吊梁专用工具,实现了对泵驱动电机整体吊装,4条锁链垂直方向受力解决了之前吊带角度过大的安全隐患,且附带的快速钩头省去了以往繁琐的绑扎吊带,既安全高效又减少了维修工时。目前海水提升泵吊梁已经投入使用,为现场维修作业提供了安全与便捷。
Taking the maintenance of the IGG cooling seawater pump in the rear cabin of the FPSO and the hoisting of the large seawater lifting pump in the front cabin as examples,this paper describes the two problems solved in the maintenance of the seawater pump of the offshore oil platform:①Solve the problem of frequent failures of the IGG cooling water pump:The causes of pump cavitation and bearing high temperature are analyzed one by one in terms of pump disassembly status,component data measurement,on-site maintenance,technological process,etc.,which can be used for reference and promotion for the troubleshooting of similar pumps.②Solve the hoisting problem of large pumps in the restricted space of the bilge:The special tools for the lifting beam of the seawater lift pump are designed and processed to realize the overall hoisting of the pump drive motor,the vertical force of the four chains solves the safety hazard of excessive sling angle,and the attached quick hook eliminates the cumbersome binding of the sling in the past,which is safe and efficient and reduces maintenance man-hours.At present,the lifting beam of the seawater lifting pump has been put into use,which provides safety and convenience for on-site maintenance operations.
