Check out the playlist of tidal and wave energy videos that the readers found most interesting in 2017.
The video shows the installation of Penguin wave energy device at the the European Marine Energy Centre (EMEC).
The Penguin wave energy converter from the Finnish wave energy developer Wello was installed at EMEC’s grid-connected wave test site at Billia Croo at the beginning of March by Orkney-based Green Marine UK.
The deployment consisted of a tree-stage operation, starting with lowering the mooring legs made of concrete blocks with heavy mooring chains to the seabed.
Spanish tidal energy developer Magallanes Renovables released the time-lapse footage showcasing the construction and launch of its 2MW floating tidal platform.
The platform, named Atir, was launched in April 2017 in Vigo, Galicia, north-west of Spain, as part of the Ocean 2G project, led by Magallanes Renovables.
The full-scale device weighs 350 tonnes, and is 42 meters long. Its two-side oriented turbine blades are 19 meters in diameter.
The time-lapse footage, released by Glasgow-based tidal energy developer Nautricity, shows the installation of its 500kW tidal energy turbine at the European Marine Energy Centre (EMEC).
The installation operation took place at EMEC’s Fall of Warness tidal test site, and was concluded on April 21, 2017.
Nautricity’s CoRMaT is a contra-rotating turbine which uses two closely spaced dissimilar rotors, moving in opposite directions, to drive the rotor and rotating stator sections of an electrical generator.
Sustainable Marine Energy (SME) showed us the recently completed installation operation of its PLAT-I floating tidal energy platform in this video.
The platform was installed on November 25, 2017, at Connel Sound, near Oban in western Scotland.
PLAT-I is a multiple turbine floating tidal energy platform hosting Schottel Hydro’s turbine system rated at 280kW.
Featuring modular trimaran design, the platform is 32 meters long, with a beam of 27 meters. The power take-off system comprises four Schottel Instream Turbines (SIT) and an accessible power conversion system hosted in an on-board container.
The story of the Subsea Power Hub development has been shared with us by the team behind the device in a video released by East Coast Oil and Gas Engineering (EC-OG).
EC-OG’s Subsea Power Hub is a hybrid device based on ocean current energy conversion system with integrated energy storage.
The device, which underwent real sea testing at the European Marine Energy Centre (EMEC) this year, operates as the self-containted turbine harnesses the energy within ocean currents to convert, store and deliver autonomous electrical power.
