The study presents a finite element analysis of a crashworthy shield of offshore wind turbines against ship bow or side collision. The model of crashworthy shield is assumed as a simply supported cylindrical shell with openings, laterally impacted by a rigid indenter. The circular holes are designed to decrease the wave-induced dynamic loads on the offshore wind turbine supporting structures. The indenter is respectively modelled as hemisphere and cuboid to represent the ship bulbous bow and broadside. The impact scenarios represent a collision between a typical 3 MW offshore wind turbine with a monopile foundation and a 5000 DWT ship. The numerical simulations performed by the LS-DYNA show that the crashworthy shield without opening can well protect the offshore wind turbines during ship bow and side collisions. The influence of the openings, the structural height and the wall thickness on the impact response of crashworthy structures is also analysed.
