摘要
针对不同环境方向组合对半潜式平台动力定位能力影响开展研究。通过不同环境方向组合,计算指定海况条件下推进器利用率曲线,获取最大和最小推进器利用率。对比计算结果发现,风浪流同向作用时不是动力定位最恶劣工况,当风、流与波浪有一定夹角时所受的环境载荷更大,推进器利用率更高。在实际平台操作过程中当风浪流不同向时,尤其是环境条件恶劣时需要及时调整平台艏向,保证平台运行安全。
The research on the influence of the dynamic positioning capability of semi submersible unit under different environmental direction combinations is carried out.Through the combination of different environmental directions,the thrust utilization curve is calculated under specified environmental conditions,and the maximum and minimum thruster utilization rates are obtained.It is found that it is not the worst case of dynamic positioning capability when the wind,wave and current are collinear.The environmental load is greater and the thruster utilization coefficient is higher,when the wind and current have a certain angle with the wave.During the actual unit operation,the wind,wave and current are non collinear,especially when the environmental conditions are severe;it needs to adjust unit heading to ensure the safe operation of the unit.
