针对具有试采及储油功能的第七代超深水钻井船进行水动力分析，求解其附加质量及幅频响应算子，并结合南海海域、巴西海域、西非海域等世界主要海洋油田生产区域海况条件进行运动响应短期预报。利用统计学算法分析了不同海况下的钻井、测试、下BOP、立管解脱工况下各浪向作业率，加权计算综合作业率。分析了不同波浪/周期组合下的钻井船各工况作业率，得到钻井船可作业海况条件。研究可为钻井船设计和钻井作业提供必要参考。

Hydrodynamic analysis of a seventh generation ultra-deep water drillship is carried out to solve added mass and response amplitude operator. Short term response prediction is made for the South China Sea, west Africa and Brazil offshore oilfield environment conditions. The operation capabilities of drilling, well testing, running BOP and riser disconnect operations in different wave direcions are studied and weighted operation capabilities in different areas are presented. Besides, the available period/wave height combinations are analyzed. The results can provide reference to the design and operation of drillship.
