FPSO单点生产滑环泄漏原因分析及解决措施

Cause Analysis and Solution for Production Swivel Leakage in FPSO Single Point Mooring

通过对友谊号FPSO单点3#生产滑环概况认真解读,明确了滑环的密封原理,并结合现场情况分析出滑环可能存在的若干问题。提出3#滑环泄漏是由于润滑不够充分;密封部位磨损、润滑油压力过低等原因所导致。针对上述泄漏的原因逐个分析,得出充分润滑,定期对密封部位进行清洗是解决问题的关键,设计了一套能够定时、定量的对高压介质滑环的密封进行润滑清洗的自动注油系统,解决滑环泄漏问题,延长了滑环的使用寿命。

In this paper, the sealing principle of swivel is clarified by carefully interpreting the general situation of the FPSO single point 3# swivel production in Youyihao, and some possible problems of the swivel are analyzed in the light of the field situation.It is pointed out that the leakage of 3# swivel is caused by insufficient lubrication, seal wear, low pressure of lubricating oil, and so on.Based on the analysis of the leakage causes one by one, it is concluded that the key to solve the problem is sufficient lubrication and regular cleaning of the sealing parts.A set of automatic oil filling system is designed to lubricate and clean the sealing of the high-pressure medium swivel regularly and quantitatively, which can solve the leakage problem of the swivel and prolong the service life of the swivel.
