摘要
随着海洋装备技术的发展,海上大型结构物的海上作业和运输任务越来越多。在此背景下,大型结构件、大型平台模块以及一些大型舰船的运输需求越来越多,大量的半潜船应运而生。在半潜船研发中,其水动力性能的研究至关重要。本文采用水动力计算软件AQWA进行某半潜船水动力性能仿真分析,计算结果表明:在常见波浪周期内,水动力系数波动较大并出现波峰/波谷;顶浪状态下运输船的运动响应数值相对偏小;横浪作用时半潜船的系泊张力最大。
With the development of marine equipment technology,there are more and more marine operations and transportation tasks for large structures at sea.Under this background,the transportation demand of large structural parts,large platform modules and some large ships is increasing,a large number of semi-submersible ships emerge at the historic moment.In the research and development of semi-submersible ships,the study of their hydrodynamic performance is very important.The hydrodynamic performance of a semi-submersible vessel is simulated and analyzed by using the hydrodynamic calculation software AQWA,considering the effect of wave loads and wind and flow loads.The results show that in the common wave period,the hydrodynamic coefficient fluctuates greatly and there are peaks/troughs;in the state of top wave,the motion response of the vessel is relatively small;in the state of transverse wave,the mooring cable tension of the vessel is the maximum.
