Analytical method to assess the crashworthiness of a Floating Offshore Wind Turbine (FOWT)

With the purpose of using more renewable energies and the decarbonisation of EU, some European countries are implementing floating wind farms, which are closer to traffic lanes. It is important to have a complete scope of the structure’s response to a ship impact, in order to implement a risk assessment of the floating wind turbines. In this regard, finite elements solvers are widely used nowadays, which provide accurate results but are time-demanding, not suitable for an early design stage. A faster and reliable method is required in order to study a wide range of parameters: impact velocity, impact location, wind-wave-structure interaction, mooring system response and overall dynamics.
This poster presents the methodology used to develop an analytical method to compute the crashworthiness of FOWT.
