Abstract:At present,more and more offshore wind farms have been built and numerous projects are on the drawing tables.Therefore,the study on the safety of collision between ships and offshore wind turbines (OWT) is of great practical significance.The present study takes the advantage of the famous LS-DYNA explicit code to simulate the dynamic process of the collision between a typical 3MW offshore wind turbine model with monopile foundation and a simplified 2000t-class ship model.In the simulation,the added mass eff...
Keywords:offshore wind turbine (OWT)  ship collision  conceptual crashworthy device  dynamic numerical simulation
