摘要
自升式钻井平台由于其特殊的船体特征,稳性计算与常规船型区别较大,计算的关键在于确定完整和破损情况下的极限重心高。在分析自升式钻井平台风倾力矩、完整稳性和破舱稳性计算要点的基础上,应用NAPA软件给出了某350英尺自升式钻井平台的稳性计算过程,阐述了风模型的建立,吃水范围、风向角间隔以及初始重心高的取法等关键点。
The stability calculation of self-elevating drilling rig was different from the conventional ships because of its special hull shape, and the major work of the calculation is to determine the maximum allowable value of the center of gravity. This paper analyzed the main effects on the wind heeling moments and the intact and damage stability calculation, and gave the calculation process of a 350 ft Jack-up drilling rig based on NAPA. The key points on modeling of wind profile, draught range, interval of azimuth angles and the initial height of the center of gravity were pointed out.
