摘要
对超深水半潜式钻井平台动力定位能力进行分析,引入粒子群优化算法进行推进器推力分配计算,编写动力定位分析程序。以超深水半潜式钻井平台为例,采用挪威德国船级社ERN计算海况条件并进行动力定位能力分析。计算结果表明,该超深水半潜式钻井平台动力定位能力满足ERN(99,99,99,99)要求,由于推进器布置及系统分割合理,在各单一推进器失效或单组推进器失效情况下,平台的动力定位能力没有明显短板。
The dynamic positioning capability of the ultra deepwater semi submersible drilling unit is analyzed.The particle swarm optimization algorithm is introduced to calculate distribution of thruster thrust and the dynamic positioning capability analysis program is developed.Taking an ultra deepwater semi submersible drilling unit for example,the dynamic positioning capability is analyzed based on ocean conditions of Environmental Regularity Numbers(ERN)in DNVGL's rule.According to analysis results,the dynamic positioning capability of unit can fulfill the requirement of ERN(99,99,99,99).Due to reasonable thruster arrangement and system split,the dynamic positioning capability of unit does not have obviously short board for each single thruster failure mode or each single group thruster failure mode.
