动力定位控制系统在第六代深水钻井船的应用

Dynamic Control System Application in the Sixth-generation Deep Water Drilling Ship

传统的锚泊定位由于受到水深的限制而无法定位,而动力定位系统则不受到水深的限制而被运用到各种深水海洋结构物中。动力定位系统是指采用推进器抵抗外界风、浪、流的环境载荷,将船舶保持在所要求的位置。而船级社DP3级的附加标志规定,任何单个故障,包括舱室的失效仍应能使海洋结构物正常的定位和作业。现以第六代深水钻井船的DP3级动力定位控制系统为例,详细说明DP控制工作原理以及船级社附加标志的相应配置要求,并结合整个控制系统在实际项目中的应用,重点阐述了DP工作网络、传感器系统、位置参考系统。最后,通过分析验证了整个控制系统满足DP3附加标志的要求。

Nowadays people gradually focus on underwater exploitation especially in deep water area. The traditional vessel position could not be applied due to the restriction of water depth. Dynamic positioning system is not limited by water depth,and can be used in many deep water vessels and offshore. Dynamic positioning system is that vessel could keep station by thruster with balance force for wind,wave,current. This article is based on the sixth-generation deep water drilling ship for dynamic position control system. Through the introduction of DP control principle and Class Notation in the study taken as the research project,the paper pays attention to concern for DP network,sensor system,position reference system,and verify entire control system satisfaction on DP3 requirement.
