摘要:
大型海洋结构物之间的碰撞是一类后果严重的海洋事故,目前,船舶与海洋平台碰撞研究较为常见,但对海洋平台与海洋平台之间的碰撞研究并不多见。针对这一问题,采用非线性有限元法建立海洋平台三维有限元模型,应用LS-DYNA对不同碰撞速度和不同碰撞角度下支持平台与钻井平台之间的碰撞过程进行数值仿真,结果显示不同工况下得到的结构的碰撞力、结构损伤及能量转化等情况有一定差别。所做研究可用于半潜式平台碰撞时结构的损伤评估。
Abstract:
The collision between large marine structures is a kind of serious marine accidents. At present, the research on collision between a ship and offshore platform is common. However, studies on the collision between ocean platforms are rare. In order to solve this problem, a three-dimensional finite element model of offshore platform was established using the nonlinear finite element method, and the collision process between the supporting platform (SP) and the drilling platform (DP) under different collision velocities and collision angles was simulated by LS-DYNA. The results show that the collision force, structural damage and energy transformation of the structures obtained under different working conditions are different. The research can be used to evaluate the structure damage of semi-submersible platform in collision.
