从移位事故谈深水钻井平台动力定位系统的安全设计

摘要

移位风险是动力定位钻井平台作业过程中面临的主要风险之一，对动力定位平台移位事故进行系统的统计与分析，是识别风险、提高动力定位系统可靠性的重要手段。文中通过对国际海事承包商协会（IMCA）最新发布的钻井平台移位事故进行分析，重点讨论了深水钻井平台动力定位系统安全设计中应关注的几个关键点。%Position loss is one of the main risks during the operation of DP drilling units. The systematic statistics and analysis of the position loss accidents of DP drilling units are an important method to identify risk and improve the reliability of DP system. This paper analyzes the accidents published by IMCA, and discusses several key aspects of the safety design of DP system for the deepwater drilling units.
