The SeaGen S system consists of twin power trains mounted on a crossbeam. The cross beam can be raised above the water for routine maintenance by winching it up the monopole support structure.
SeaGen S is suitable for marine environments in water depths up to 38m and achieves rated power in tidal currents of greater than 2.4m/s.
The 1.2MW system installed in Strangford Lough, Northern Ireland, in 2008 has been subject to 4 years of extensive testing.
MCT is bringing a 2.0MW SeaGen S Mk 2 product to market for use in commercial scale tidal projects, including the demonstration array projects initiated by MCT.
The SeaGen S Mk2 product has incorporated a number of design changes following testing of the system in Strangford, with the most significant being an increased rated power to 2MW and an increased rotor diameter to 20m.
