[en] In a context of ecological issues, renewable energy systems are developed and enhanced and, amongst them, offshore wind energy. Many wind farm projects will be carried out in the near future and their locations are closer and closer to traffic lanes. For safety, ecologic or economic reasons, it is required to perform a collision risk analysis for each new offshore structure.
Finite elements softwares, widely used actually, provide accurate results but are time-demanding and not suitable for a first design stage. A faster analytical method, based on the plastic limit analysis, is developed by the authors to compute the resistance of an offshore
wind turbine jacket when collided by a ship.
This poster presents the methodology used to develop an analytical method to compute the crashworthiness of jackets. Then, some results are given and compared to numerical simulations to validate the model.
