CorPower Ocean has resumed deployment of its first commercial scale C4 wave energy converter, following a period where the Aguçadoura wave energy site off Portugal was out of operation.
Earlier this year, CorPower Ocean identified cable damage at the offshore site.
It initiated a series of operations to recover and refurbish the electrical export cable involving ROVs and offshore construction vessels, which was successfully concluded in June.
With the site infrastructure restored, CorPower Ocean has resumed the C4 deployment programme by testing operational methods for connecting and disconnecting its C4 device.
This follows the successful site installation of the UMACK anchor and subsea electrical export cables in mid-2022 and the completion of C4 assembly and successful pre-deployment check at the quay-side launch pad in Viana do Castelo in December 2022.
During recent weeks innovative methods for pulling down and mating the C4 device to the UMACK anchor using a fully surface operated installation sequence have been verified.
In the next phase of the program the C4 device will be taken through cycles of testing safety, control and grid functions, followed by first power export to the Portuguese grid.
CorPower Ocean is undergoing certification of the C4 technology with DNV – a leading supervisory to the global renewables industry – to ensure reliability of components and systems in the marine environment.
For marine operation methods Global Maritime is acting as Marine Warranty Surveyor on behalf of underwriters to ensure compliance with offshore standards.
