摘要
采用水动力学软件AQWA和有限元方法,分别对三浮体平台、四浮体平台和五浮体平台在极限海况下的工作状态进行数值仿真,并对3种半潜平台的频域和时域运动响应进行分析。结果表明:在频域分析中,三浮体平台、四浮体平台和五浮体平台在纵荡、垂荡和纵摇方向上的附加质量依次增大,运动响应依次减小;在时域分析中,3种半潜平台在横荡、垂荡和横摇方向上的运动响应均减小;平台的稳定性随平台结构复杂度的增加而提高,但与四浮体平台相比,五浮体平台稳定性的提高不显著。
Numerical simulations were conducted on motion responses of the three-floating three-column,four-floating four-column and five-floating five-column semi-submersible platform in complicated marine environments using hydrodynamic software AQWA combined with finite element analysis,while their frequency-domain response and time-domain response were analyzed.Results show that in the frequency-domain analysis,the added mass of the three-floating three-column,four-floating four-column and five-floating five-column semi-submersible platform increase sequentially in the sway,heave and roll direction,and their motion response decreases in turn;in the time-domain analysis,the sway,heave and roll motion response of all the three floating platforms reduce.With the increase of structure complexity,the stability of above platforms improves.Compared with the four-floating four-column platform,the increase in stability of the five-floating five-column platform is not obvious.
