摘　　要：以3 000 m水深DP-2级动力定位半潜平台为算例,研究在风浪流同向作用下,平台在各个角度下所能抵抗的最大外界环境力,得到最优作业方向。在此角度下,着重分析当不同推力器失效时,对动力定位能力的影响。得到一般规律,并推广到一般平台。Taking a semi-submersible platform with a DP-2 dynamic positioning system working in 3000m depth water as an example, a research is taken on the maximum force of external environment, in which a platform can resist at various angles with the same direction of wind wave and current, and then an optimal operational direction is obtained. An analysis is made on the impact of different thruster failure on the dynamic positioning capability. Finally, a general discipline is obtained and can be extended to common platforms.
