Undesired motions in Floating Offshore Wind Turbines (FOWT) lead to reduction of system efficiency, the system’s lifespan, wind and wave energy mitigation increment stress on maintenance costs. In this article, a new barge platform structure for FOWT has been proposed with objective reducing these undesired motions. The newly aims reduce tower displacements platform’s oscillations, particularly...

This work focuses on the geometry effects over performance of oscillating water column (OWC)-type wave energy converter (WEC) systems and searches for OWC geometries that enhance efficiencies under same conditions. To analyze hydrodynamic performances WEC systems, an in-house smoothed particle hydrodynamics (SPH) code based weakly compressible fluid approach is utilized. The efficiency enhancem...

Abstract Systems based on the OWC principle allow to convert sea-wave energy into electrical energy. The potential contained in wave motion is first converted pneumatic of a bi-directional airflow, generated by oscillatory displacement column water inside chamber. Then, an air turbine, such as Wells placed at top chamber, converts mechanical its shaft, which can be coupled electric motor produc...
