Technology       'simple, robust and low cost'

Two independent studies assessed early tidal and wind technology to identify the most economically reliable TST as a simple, robust, gearless axial flow turbine:

To minimise CapEx and OpEx, offshore specialists CB&I John Brown transferred standard offshore technology and operations to form the basis for a new support structure concept. In collaboration with Swansea University, using rotordynamic modelling, the concept was designed to allow simple installation and maintenance retrieval in both shallow and deep water and to minimise vibrations, hence increasing the maintenance period.

 A gearless low speed generator offers a high efficiency over a range of speeds with minimal maintenance demands through the use of novel structural and electromagnetic topologies

 A simple, robust and serviceable yawing mechanism is used for maximum flow capture and the use of patented materials, developed by Corus will form the gravity base.
