| 摘 要： | 针对半潜式钻井平台锚泊辅助动力定位系统在海上作业时可能会出现的单缆失效情况。以一艘半潜式平台为例,设计锚泊辅助动力定位系统。通过全动态时域模拟,研究不同的单缆失效模式对半潜式平台锚泊辅助动力定位系统功率消耗、定位精度、缆绳张力等的影响。根据分析结果,在极端海况下,松弛锚泊辅助动力定位系统的背风缆有助于降低定位系统的功率消耗,提高定位精度和系统的安全性,从而为锚泊辅助动力定位系统的工程应用提供一些参考。

| Abstract: | For a semi-submersible platform,one mooring line may fail when the mooring-assisted dynamic positioning system works in the sea.As an example,a semi-submersible platform has been considered and a mooring-assisted dynamic positioning system has been designed.By using the time domain simulation,the impact of one mooring line failure on the offsets and power utilization of the platform will be analyzed.From the analysis result,it is suggested that under severe conditions,loosing the tension of the leeward lines can reduce power consumption,improve positioning accuracy and the safety of the positioning system,which will be helpful to the further engineering applications of the mooring-assisted dynamic positioning system. |
