Toward a Risk Based Simulation for the Erection of an Offshore Windmill Park

Nowadays, EU shipyards that are facing difficulties due to the global crisis are often trying to diversify their activities. Some of them have already turned to the production of offshore windmill components. The installation and operation of offshore windmills are much more complex than onshore due to the distance and the depth of the water column. This creates problems specific to the production, installation and maintenance of offshore wind turbines. A tool for sequencing and installation simulation has been developed to assess the risks associated to the assembly of wind turbines parks via simulations of the different phases of construction considering various random phenomena such as weather conditions and uncertainties on production time.
