Moving the Orbital O2 (Image: Orbital Marine Power) Orbital Marine Power’s 2MW O2 – a floating turbine anchored in the Fall of Warness – is connected via a subsea cable to the local onshore electricity network. About 15m below the O2’s 72m-long superstructure, two fully integrated power trains from SKF are attached on two wing-like legs. Here the twin-bladed rotors rotate, each with a diameter of 21m, the largest ever on a single generating platform to date, driven by the tidal current.
