Offshore electrical power generator

MARMOK-A-5 is an offshore electrical power generator that uses wave energy to create electricity. This device is a spar buoy installed in the maritime testing site BiMEP, in the Bay of Biscay. It is the first grid-connected maritime generator in Spain, and one of the first in the world.

Developed by the Basque company Oceantec Energias Marinas inside the European project OPERA, it is delivering electrical energy to the grid since December 2016. The buoy is located in the ocean, 4 km from the coastline and is connected to the sea with a submarine electrical cable. With a nominal power of 30 kW, the principal aim of the MARMOK-A-5 device is obtaining results in the way of designing a new generation cost effective high power marine energy generator.

Principle

The operation principle of MARMOK-A-5 is a point absorber OWC (Oscillating Water Column). The device is 5m in diameter and a length of 42m, 6m above the water. It has a weight of more than 80 tons. The buoy is floating in a 90m depth and is tied to the sea bed with a mooring system based on anchors. This wave energy converter has demonstrated its robustness surviving difficult environmental conditions with waves as big as 12m.

History

As noted above, the concept was initially developed by Oceantec within the European OPERA project.

Further development in EuropeWave programme

IDOM were one of seven companies awarded pre-commercial procurement funding in December 2021 for Stage 1 of the EuropeWave programme, to further develop the device concept. In September 2022, they progressed to Stage 2 with additional funding for a Front-End Engineering and Design study of a scale-prototype to be tested at sea. IDOM were one of three concepts that progressed to Stage 3, with a share of the €13.4m budget to develop and test a device at BiMEP for a year.
