Experimental investigation of taut leg moored FOWTs in damaged conditions

This study presents an experimental investigation focusing on the performance of a taut mooring systems for Floating Offshore Wind Turbines (FOWTs) under accidental limit state scenarios. These tests are part of the data obtained during the experimental campaign conducted at the Ship Hydromechanics Laboratory of Delft University of Technology, aimed to assess the behavior of FOWTs under various conditions, including operating, extreme, and failure scenarios. All the data related to the experiments are freely downloadable from this link. The experimental analysis conducted in this work focuses on simulating various failure scenarios, such as the rupture of mooring lines and turbine blade actuators considering two different mooring configurations. Results show that in such scenarios, taut mooring systems possess design characteristics that mitigate the risk of additional damage to the floating system and underscores the importance of understanding and mitigating risks associated with accidental limit states in offshore platforms, particularly by optimizing mooring configurations and materials to enhance overall safety and resilience.
