This study investigates the integration of Oscillating Water Columns (OWCs) into Semi-Submersible Floating Wind Turbines (FWTs) to enhance offshore energy harvesting. The synergistic combination of OWCs with FWTs aims to mitigate oscillatory motions induced by waves and winds, thereby optimizing system efficiency and prolonging lifespan. Through the redesign of the original FWT platform, named WINDMOOR, this research explores the incorporation of OWCs within two out of three columns of the existing semi-submersible structure, tailored for a 12 MW FWT system. The redesign process prioritizes considerations of hydrostatic stability and hydrodynamics, essential for accommodating the additional OWC elements. Hydrodynamic analyses are conducted to evaluate the hybrid platform’s response compared to the original configuration, emphasizing reductions in oscillatory motion. The results demonstrate the potential benefits of integrating OWCs within FWT systems, particularly in enhancing power performance and structural design resilience. This study contributes to advancing offshore energy harvesting technologies, offering insights into the feasibility and efficacy of hybrid systems for sustainable offshore renewable energy production.

摘要

This study investigates the integration of Oscillating Water Columns (OWCs) into Semi-Submersible Floating Wind Turbines (FWTs) to enhance offshore energy harvesting. The synergistic combination of OWCs with FWTs aims to mitigate oscillatory motions induced by waves and winds, thereby optimizing system efficiency and prolonging lifespan. Through the redesign of the original FWT platform, named WINDMOOR, this research explores the incorporation of OWCs within two out of three columns of the existing semi-submersible structure, tailored for a 12 MW FWT system. The redesign process prioritizes considerations of hydrostatic stability and hydrodynamics, essential for accommodating the additional OWC elements. Hydrodynamic analyses are conducted to evaluate the hybrid platform’s response compared to the original configuration, emphasizing reductions in oscillatory motion. The results demonstrate the potential benefits of integrating OWCs within FWT systems, particularly in enhancing power performance and structural design resilience. This study contributes to advancing offshore energy harvesting technologies, offering insights into the feasibility and efficacy of hybrid systems for sustainable offshore renewable energy production.
