Magallanes Renovables’ ATIR turbine is now on route from Spain to Scottish tidal energy test site EMEC.

Spanish tidal energy developer Magallanes Renovables’ full scale ATIR tidal turbine which has been successfully validated and optimised is, at the time of writing being towed north from Vigo in Spain and is expected to arrive in Orkney waters in mid-September.

Once the device arrives in Orkney, local marine contractor Leask Marine will install the ATIR at EMEC’s Fall of Warness grid-connected tidal test site. Here the device will be exposed to the site’s strong tides which can reach up to four metres per second, conditions which will allow the ATIR to demonstrate its maximum operational performance.

The deployment of the ATIR is part of the OCEAN_2G project, which aims to test, validate and pre-certify Magallanes’ second generation (2G) 2MW tidal platform. The project is led by SAGRES - Magallanes Renovables’ parent company and the project consortium brings together EMEC, Orkney-based marine services provider Leask Marine, and electrical specialists IM FutuRe.

The 45 metre ATIR was built and launched in Vigo, and features a 25 metre draft which supports two 19 metre diameter rotors. The platform has been designed to be anchored to the seabed by mooring lines at the bow and stern, while the striking yellow and red steel-built tidal platform floats on the surface.

As 400kW generation was achieved during tow testing, the aim now is to build up the ATIR’s power output to 2MW while installed at EMEC, readying it for market.
