在深水及超深水动力定位钻井船(平台)钻井作业过程中,环境(风、浪、涌)改变,动力定位控制系统或动力系统的突发状况使平台产生位移,严重将造成平台、隔水管、防喷器及井口的损坏,造成人员、环境、设备及经济损失。而Watch Circle将动力定位系统与钻井作业状态,隔水管分析,水下设备安全结合起来,通过动力定位及EDS(Emergency Disconnect System)的及时反应,为作业安全提供保障。
During the drilling operation of deepwater and ultra-deepwater hydrodynamic positioning drilling vessels (platforms), the environment (wind, waves and surges) changes, and the sudden situations of the dynamic positioning control system or power system make the platforms displace, which will seriously damage the platforms, risers , BOP and wellhead damage, resulting in personnel, the environment, equipment and economic losses. Watch Circle combines the dynamic positioning system with drilling operations, riser analysis, and underwater equipment safety to provide operational safety through dynamic positioning and timely response to the EDS (Emergency Disconnect System).
