Wave energy start-up Mocean Energy has teamed up with Chrysaor, subsea energy storage experts EC-OG and AUV specialist Modus in a project to look at using renewables for subsea power.
The project, funded by the partners together with the Oil and Gas Technology Centre (OGTC), will look to use Mocean Energy’s Blue Star wave energy converter and EC-OG’s HALO subsea energy storage system to power subsea tiebacks or residential AUVs.
If industry feedback is positive, the partners will press ahead with a technology field trial using a Mocean Energy prototype in the seas off Orkney later this year. Once proven, these technologies could provide vital backup power in case of umbilical failure, with potential to provide green power for future fleets of autonomous AUVs.
Mocean – a graduate of the OGTC’s TechX accelerator programme – secured £3.3 million from Wave Energy Scotland in 2019 to build and test a half-scale version of its technology at sea. The device is currently being fabricated.
“Our first step will be an industry workshop at the OGTC in Aberdeen on 27 February where we will gather information on real-world applications and our field trial plans,” said Mocean Energy managing director Cameron McNatt. “We then plan to forge ahead with a field trial later this year at our test site in Orkney.”
Modus chief commercial officer Nigel Ward added: “This project will demonstrate capability to provide temporary or semi-permanent modular subsea residency for HAUV systems controlled by over the horizon technology. This innovative approach to survey and inspection will reduce the numbers of personnel offshore, providing significant safety benefits and cost savings.”
