摘要
半潜式平台由于工作水深大,与其他类型的海洋平台相比,其在工作状态下遭遇船舶碰撞的风险最高,事故后果也最为严重。基于非线性动力学分析方法,以某半潜式平台为例,在考虑破损稳性的基础上,对其遭遇船舶碰撞的结构损伤和动力响应进行分析,并进一步针对主要撞击参数的影响进行了研究,为考虑碰撞载荷的半潜式平台结构设计提供参考。
Compared to other types of offshore platforms, Semisubmersibles suffer from higher risk of encounteringcollision and worse aftermath due to large working drafts during operation. Based on the nonlinear dynamics analysis method and taking an submersible platform as the example, the structural damage and dynamic response of semi/vessel collision is analyzed, on the basis of considering the damage stability; moreover, the influence of main impact parameters are studied to provide some reference for semisubmersible structural design considering collision load.
