The aim of this project is to assess the feasibility of Re-using Existing Ship structures for large-capacity Wave Energy Conversion (RESWEC) to support a novel configuration of an oscillating water column array. The project will demonstrate the technical feasibility of creating the WaveShip, a zero-emissions mobile renewable energy platform, by showing that a near end-of-life ship can be repurposed whilst retaining satisfactory structural and stability characterisitcs to meet the environmental conditions encountered on the open oceans. This project will prove the naval architectural principles underpinning the WaveShip concept are sound, supported by a physical model testing campaign to validate analytical results. Vendor-supplied information will be used to show how existing turbine and generator technologies can be brought together to create a wave energy harvesting system, that will then be employed in the clean and sustainable production of hydrogen, which will be compressed and stored onboard in readiness for offloading. Successful completion of Project RESWEC will pave the way to ensuring the world's first 'Renewable Energy FPSO' becomes a viable and credible reality.
