Performance Analysis on the Use of Oscillating Water Column in Barge-Based Floating Offshore Wind Turbines

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 rotational movements. This is achieved by installing Oscillating Water Columns (OWC) within oppose oscillatory motion waves. Response Amplitude Operator (RAO) used predict exposed different frequencies. From RAOs analysis, performance evaluated representative regular periods. Simulations using numerical tools show positive impact added OWCs stability. results prove that presents better decreasing oscillations given range frequencies, compared traditional platform.
