摘要: 考虑到动力定位能力分析在船舶设计中的重要作用,对深水半潜式起重铺管船动力定位能力进行分析。采用软件计算结合同类型船风洞试验系数修正的方法,计算作业环境条件下的环境载荷。针对选定的推进器配置及失效模式,计算14组工况下的船舶动力定位能力,给出各工况的动力定位能力曲线。结果表明,推进器配置合理,满足设计条件。

Abstract: Considering the important role of dynamic positioning (DP) capability analysis in ship design, DP capability of deepwater semi-submersible crane and pipe-laying vessel is analyzed. Environmental loads in operation condition are calculated with software calculation results corrected by wind tunnel test coefficients of the same type vessel. According to the selected thruster configuration and failure mode, DP capability of 14 conditions is calculated, and the DP capability plots are shown. The results show that the thruster configuration is reasonable to meet the design conditions.
