波浪作用下30万吨级油轮撞击能量研究

Collision energy of 300000 t tanker under wave action

通过物理模型试验,研究不规则波作用下30万吨级油轮撞击能量,分析了主要影响因素HT、LB、TT0、D对撞击速度的影响规律。结果表明:撞击速度与HT成正比;与LB成幂次关系;与TT0也成正比,但TT0=1时船舶撞击码头与波浪产生共振,撞击速度出现极大值;压载时的撞击速度大于满载时的撞击速度,撞击速度与吃水成负相关。提出了30万吨级油轮撞击能量的计算公式,与青岛港原油码头三期工程和青岛益佳集团燃油码头工程的物理模型试验结果对比,具有较好的计算精度,可供工程设计参考。

This paper investigates the impact of irregular waves under a 300 000 t tanker collision energy by physical model test and analyzes the main factors＇ impact on collision velocity including H/T, L/B, T/To, D. The result indicates that the collision speed is proportional to H/T and T/T0, and is powered to L/B. When T/T0 = 1, the collision and wave resonates, which causes the greatest velocity. The collision speed when the tanker is ballast is larger than that when it is fully loaded. In another word, the collision speed is negatively correlated with the draft. A formula for the 300 000 t tanker collision energy is proposed and compared to the result by physical model test of Qingdao port oil wharf phase III project and Qingdao Yijia Group oil terminal project, which has better accuracy and can be used for reference for design.
