摘要
为了获得施加在海洋平台上的最终和合力与合力矩,并希望知道每个推进器提供的各个分力的大小以及各个全回转式推进器的空间方位角,对海洋平台的动力定位性能进行了单独的研究。基于VC++6.0设计了一种动力定位二维模拟评估软件,并结合海洋石油981的具体推力分布策略和8个全回转推进器的分布情况对该海洋平台在位运行情况下进行了南海海域不同流向和浪向下的动力定位特性仿真与评估。通过仿真发现,风浪流的变化对于动力定位过程的影响是不同的。
A special study on the dynamic positioning performance of the offshore platform is conducted as it is necessary to obtain not only the final resultant forces and resultant moments on the offshore platform,but also the magnitude of each component force provided by each thruster and the spatial azimuth angle of each azimuth thruster.Visual C++6.0 software is used to design a dynamic positioning two-dimensional simulation evaluation software(DPTSE),combined with the specific parameters of Offshore Platform 981,the thrust allocation strategy and the detailed layout of eight azimuth thrusters,the dynamic positioning process of the offshore platform in the South China sea with different current and wave directions are simulated and evaluated.Through simulation,it is found that the influence of wind,wave and current changes on dynamic positioning process is different.
