Abstract
This paper presents an integrated floating dual-chamber Wave Energy Converter system designed for offshore wave energy harnessing in the Aegean Sea. The study utilizes optimized geometric configurations and mooring characteristics for an Oscillating Water Column, which incorporates a dual coaxial hollow cylindrical structure. The analysis considers the specific environmental conditions anticipated at the deployment site. To evaluate the feasibility of the proposed technology, a hydrodynamic analysis is conducted, incorporating solutions to diffraction and pressure-and motion-dependent radiation problems associated with the moored converter. Additionally, comprehensive experiments using a scaled model are performed to simulate the behavior of the oscillating water column device under operational and extreme sea state conditions at the intended installation location to validate the theoretical predictions. The detailed comparisons demonstrate a strong agreement, thereby confirming the accuracy of the applied modeling approach in the preliminary design stages of dual-chamber oscillating water column devices.
