Research on the lines optimal design and resistance calculation of drilling ship based on CFD

为了对钻井船阻力性能进行优化,以某钻井船为研究对象,通过建立首尾部半参数化船体模型,针对月池关闭状态下的钻井船,对其首尾部的型线进行优化,选出最佳优化方案。钻井船的首尾部型线经过优化后,总阻力降低了2.003%。其中,摩擦阻力降低0.13%,剩余阻力优化效果为8.9%。本文研究可为钻井船的型线设计优化提供一定的参考和建议。

In order to optimize the resistance performance of the drilling ship,a drilling vessel was taken as the research object,through establishing the semi-parametric hull model of the fore and aft parts,the bow and stern parts of the drilling vessel were optimized by CFD method under the consideration of the closing of the moon pool,and the optimal optimization scheme was selected.After optimizing the bow and stern profile of the drilling vessel,the total resistance was reduced by 2.003%,in which the frictional resistance was reduced by 0.13%and the residual resistance was optimized by8.9%.The research in this paper can provide some references and Suggestions for the optimization of drilling vessel profile design.
