Full-Scale Test SeaGen achieved its rated power of 1 2MW f
SeaGen achieved its rated power of 1 2MW for the first time in December 2008 and is fully operational at the time of writing Generated electricity is being sold and SeaGen is officially accredited as the UK s first marine generating station with the UK grid authority OFGE

Mooring Configuration Jacketed quadrapod structure with 4 pinpiles each of 1m diameter penetrating 9m into bedrock. SeaGen can also be supplied on a 3.5m monopile and its predecessor the 300kW Seaflow was installed on a 2.1m diameter monopile.  +
Optimum Marine/Riverline Conditions Rated velocity is 2 4m s for SeaGen protot
Rated velocity is 2 4m s for SeaGen prototype but this can be re set at any value between 2 0 and 2 5m s depending on site conditions Through use of pitch control power is limited to rated level With 16m diameter rotors the minimum water depth is 22m and the maximum convenient depth is 40m We have systems under development that could operate in either shallower water possibly down to 10m and deeper water up to 60m

Scale Test As mentioned before they ran a small proof
As mentioned before they ran a small proof of concept test system back in 1994 3 5m rotor 15kW which they believe was the world s first tidal turbine They ran a 300kW 11m rotor experimental test rig called Seaflow since 2003 which was and still is the only tidal turbine world wide in a truly offshore location Neither was a model as such of our commercial SeaGen technology but they both tested various key elements for example pitch controlled axial flow rotors and the necessary dcontrol systems
