Ship collision on offshore wind turbines

In a context of development of renewable energies, large offshore wind farms are being built close to traffic lanes and collision risk analysis on supporting structures is becoming a major concern. The aim of this paper is to present an overview on the ship – Offshore Wind Turbine (OWT) collision events. The behaviour of the OWTs structure with monopile and jacket foundations is investigated by means of numerical simulations. Furthermore, an analytical approach is presented for assessing the crashworthiness of the jacket foundation.
