摘要
基于三维势流理论对船舶碰撞海上风电升压站平台的动态过程进行仿真分析。定量分析船舶碰撞速度、护舷等效刚度、船舶吨位等参数对碰撞力的影响规律,提出碰撞力的实用计算公式,并与多国规范进行对比,验证公式的适用性;针对工程中碰撞体间刚度的非线性,在计算公式中引入护舷非线性刚度系数,改善碰撞力计算体系;研究不同护舷材料性能及布置方式对海上风电升压站平台防撞性能的影响,提出海上风电升压站平台护舷选型及布置原则;结合实际海上风电工程海况条件,再现船舶与海上风电升压站平台碰撞的时域过程,以期为升压站平台结构设计提供依据。
In this paper,the whole dynamic collision process between ship and offshore electric substation platform is simulated and analyzed based on three-dimensional potential flow theory.The effects of ship speed,equivalent stiffness of fender and ship tonnage on collision force are analyzed quantitatively.An empirical formula for calculating the collision force between ship and electric substation platform is put forward,and the applicability of the formula is verified by comparing it with the codes of other countries.The introduction of the nonlinear stiffness coefficient of fender greatly improves the calculation system of collision force.The effects of different fender material properties and layout methods on the anti-collision performance of offshore electric substation platforms are studied,and the selection and layout principle of fender for offshore electric substation platforms are put forward.Combined with the actual sea conditions of offshore wind power,the time-domain process of the collision between ship and the offshore electric substation platform is reproduced,which provides construction guidance for the actual project.
