深水钻井船运动性能分析

Analysis of motion performance for a deepwater drilling ship

采用数值计算与模型试验相结合的方式研究深水钻井船的运动性能。对某钻井船的垂荡、横摇和纵摇运动进行短期预报,并衡量钻井船在特定海况下的钻井作业能力;同时,针对钻井船具有较大月池开口这一特点,分析研究了月池开口对钻井船运动性能的影响。

This paper studies motion performance of a deepwater drilling ship by numerical calculation and model test. It predicts short-term responses of heave, roll, and pitch for the drilling ship, and evaluates its capability of the drilling operation under the given sea conditions. Moreover,it also analyzes and studies the influence of the moonpool on the motion performance of a drilling ship due to the characteristics that a drilling ship has a larger moonpool.
