Wave excitations cause structural vibrations on the Oscillating Water Columns (OWC) lowering the power generated and reducing the life expectancy. The problem of generator deterioration has been considered for the Mutriku MOWC plant and a machine learning-based approach for prognosis and fault characterization has been proposed. In particular, the...

Marine structures like Floating Wind Turbine (FWT) is exposed to the oncoming waves and wind that can cause oscillatory motions within the system. These undesired oscillations can have negative impacts on the efficiency of the system, reduce its lifespan, hinder energy extraction, increase stress levels, and raise maintenance costs. To mitigate the...

The inherent oscillating dynamics of Floating Offshore Wind Turbines (FOWT) might result in undesirable oscillatory behaviour in both the system states and the generated power outputs, leading to unwanted effects on critical, extreme and fatigue loads, and finally to a premature failure of the facility. Therefore, this kind of system should be capa...
