Oceantec Energías Marinas has posted an image showing a worker accessing its Marmok-A5 wave energy device for equipment supervision work.
The device was installed at Bimep testing site, off northern Spain, in October 2016 as part of the EU-funded OPERA project that aims to halve the cost of wave energy.
Marmok-A5 is a point absorber oscillating water column, shaped like a giant buoy with 5 meters in diameter, 40 meters height and weight of around 70 tonnes.
It uses the power of the waves to spin turbines that drive an associated electricity generator, which can produce up to 30kW, which is enough to run a medium sized business, according to the University of Exeter, part of the 12-member consortium participating in the project.
The device generates power when the waves cause water column to rise and fall, compressing and decompressing the air above, which spins the turbines to drive an electricity generator.
