The Research Project

Current offshore renewable wind energy practice requires the installation of large fixed and floating structures offshore. The mooring system is one of the important components for a floating offshore wind turbine (FOWT). Accurate assessment of the mooring lines is fundamental both in normal/operating and survival conditions. Recent accidents due to extreme weather events have highlighted the risk that improper design of floating structures can have on the structure’s integrity and the environment. Studies shall be performed to investigate the mooring system effect on the overall performance of an FOWT structure. Moreover, the investigation of the importance of the interconnection between the FWOT and the mooring line is therefore crucial.

The goal of this project proposal is to fill this gap in the knowledge by conducting a PhD investigation into the effects of the mooring systems on the operability and survivability of an FWOT structure. Both numerical and experimental approaches are considered in this project to investigate the role of the mooring systems. The numerical approach considers the development of the NewWave and Computational Fluid Dynamics (CFD) techniques due to their compatibility with the modelling of extreme waves. The study aims at establishing efficient numerical modelling techniques for dynamic motion response and structural assessment, including fatigue analysis due to extreme weather conditions.

The experimental investigation considers a systematic series of scale model test at AMC testing facilities that will be used for the validation of the numerical models.
