'Oceanus 2' completed
Mon, 07 July 2014
In the UK, A&P Falmouth has completed its second major renewables project, after leading wave energy firm Seatricity’s next generation Oceanus 2 device has left the docks for Wave Hub. The wave energy converting device – a 10m diameter floating ring made from marine grade aluminium - will be the first device to be deployed for testing at Wave Hub, the offshore renewable energy test facility 10 miles off the coast of Hayle.
It was built in the fabrication workshops, assembled on the quayside and deployed from a wharf at A&P’s shipyard in Falmouth. If testing is successful, it will pave the way for the manufacture of a further 60 devices.
Seatricity plans to develop a full-scale 10MW grid-connected array over the next two years at Wave Hub, just a short distance from the Falmouth shipyard.
Paul Weston, A&P Falmouth’s Renewable Energy Technical Manager told Maritime Journal: “Having successfully manufactured, deployed and recovered Fred Olsen’s Lifesaver, the first device to be installed at FabTest, the nursery test site for wave devices in Falmouth Bay, A&P Falmouth has now completed the manufacture of the first device for Wave Hub. This clearly demonstrates our commitment and investment in the marine renewables industry, and shows we have the ability, skills and technical expertise to provide a one-stop shop for developers.”
In the simplest terms the device travels up and down with the waves and operates a pump to pressurise sea water to drive a hydroelectric turbine to produce electricity.
The float is tethered to blocks on the seabed and the pumps are linked together to generate substantial amounts of highly pressurised water. This pressurised sea water can also be used for directly producing fresh water by the reverse osmosis desalination process. Both fresh water and electricity can be produced simultaneously.
Peter Mitchell, Managing Director of Seatricity said: “The technology is scalable so once we complete our testing at Wave Hub this year we hope to move quickly to a full array. The final array of up to 60 devices in 2016 will generate 10MWs of electricity - enough to power 10,000 homes - and would be one of the largest wave farms in the world.”
