Seakeeping analysis of two ships advancing parallel for underway replenishment

  • 摘要:   目的  船舶在并行补给过程中不仅受风浪的影响,还受两船间水动力的相互干扰,会产生比单船运动更强烈的摇荡运动。为研究补给过程中船舶的耐波性,  方法  利用商用水动力学软件AQWA求取补给船与接收船摇荡运动的RAO函数,根据频域的计算结果进行不规则波下的响应幅值预报与时域分析,并采用相关函数的方法求得时域下的有义值。经与谱分析结果进行的比较,发现两者吻合较好。  结果  研究结果表明,两船间的水动力干扰对补给过程影响较大。  结论  所得结果可以避免补给过程中发生危险状况,确保补给作业安全。
