摘要
动力定位能力分析对于推力器选型和推力器的配置选型,以及对于一条新设计的动力定位船舶的定位能力的初步检验具有重要意义。动力定位能力分析能够得到船舶在各个艏向角抵抗环境力的能力。文章通过自主开发的程序研究了半潜平台在推力器失效模式下的定位能力,对该程序中的推力分配方法进行了详细的阐述,并对某半潜平台的动力定位能力分析验证了该程序的可行性。研究推力器失效时船舶的动力定位能力,不但可以验证船舶定位时的安全性,而且还可以为推力系统的设计提供适当的建议。
Dynamic positioning capability（DPCap） analysis is very important to the selection of thrusters and their configuration and the preliminary investigation of positioning ability of a newly designed dynamic positioning vessel. DPCap analysis can obtain the maximum environmental forces that the DP system can counteract for a given heading. In this paper, a program is self-dependently developed to investigate the dynamic positioning capability of a semi-submersible considering thruster failure mode. The thrust allocation logic of the program is specifically illustrated. The feasibility of the program is demonstrated by a DPCap analysis for the semi-submersible. The research on the DPCap analysis considering thruster failure mode could demonstrate the safety of the DPS and provide adequate guidance to the design of the thrust system.
