摘要： 为了分析月池形式及尺寸变化对钻井船二代稳性中参数横摇和过度加速度薄弱性衡准评估的影响,文章针对1艘钻井船,考虑3种开孔形状、不同尺寸的月池形式,验证分析其是否满足正在制定的第二代完整稳性衡准。分析结果表明：月池形状及尺寸变化会影响参数横摇和过度加速度薄弱性衡准参数值,文中考虑的月池形状及尺寸的钻井船均满足衡准要求。该文结果可为钻井船月池的设计提供参考。

Abstract: The influence of the shape and the size of the moonpool on the vulnerability criteria assessment of the parametric roll and the excessive acceleration in the second generation stability has been analyzed for a drillship. This article considers the drillship with three moonpools of different opening shapes and different sizes to verify and analyze whether the drillship meets the second generation intact stability criteria under development. The analysis results indicate that the variation in the shape and size of the moonpool can affect the parameters of the vulnerability criteria of the parametric roll and the excessive acceleration for the drillship. The drillship with the moonpool of the shapes and sizes considered in this study can meet the criteria requirements. It can provide reference for the design of the drillship's moonpool.

Key words: second generation stability, parametric roll, excessive acceleration, drillship, moonpool
