摘要
为了减小超大型结构物在干拖运输过程中所受的加速度,提出利用波浪势流理论及运动响应控制条件的数值模拟方法,以迄今为止世界规模最大半潜式"海上渔场"从中国青岛干拖运输至挪威为例,研究海况、航行吃水及系统重心高度等不同参数下,半潜船的运动响应和超大型结构物的加速度,获得不同参数的影响规律。结果表明,数值模拟结果与工程实际数据吻合较好,验证了该方法的有效性,可为类似减小加速度的干拖运输分析提供参考。
To reduce the accelerations of super-large structure during dry tow transportation,a numerical simulation method of using wave potential theory and the control condition of motion responses is proposed.Take the dry tow transportation of the world’s largest semi-submersible fish farm from Qingdao to Norway as an example,the ship motion responses and accelerations of the super-large structure were studied under different parameters,including sea state,sailing draft and system vertical center of gravity etc.,and the influence law of different parameters was obtained.Results show that the numerical simulation results agree with the practical data,indicates this method is effective and can provide reference for the accelerations reduction analysis of similar dry tow transportation.
