海洋自升式钻井平台加装推进系统适用性计算分析

Applicability Calculation and Analysis for Installing Propulsion System on Offshore Jack-up Drilling Platform

分析对比适用于自升式平台推进系统的优缺点,并对3种不同船型的自升式平台进行水动力计算,设计推进系统布置方案。推进系统校核结果表明,各平台推进器布置方案均能满足给定海况条件下DP 1级动力定位要求,平台可实现短距离助航和辅助就位。结合平台实际使用情况,设计推进器共享方案,以提高平台加装推进器的经济性。

The advantages and disadvantages of the propulsion system for jack-up platform were analyzed and compared,and the hydrodynamic calculation for three different ship types of jack-up platform was carried out to design the propulsion system layout.The verification results of propulsion system showed that the layout of each platform can meet the DP 1 dynamic positioning requirements under given sea conditions,and the platform can achieve short-distance navigation assistance and precise positioning.Combined with the actual use of the platform,the propeller sharing scheme was designed to improve the economy of the platform to install the propeller.
