Orbital Marine Power SR250
The SR250 is an axial flow turbine that has a reduced power rating of 250 kW. The hull comprises a 29m long steel tube with a 2.2 m diameter. The rotors are each suspended from separate rectractable rotor legs attached to the buoyancy tube, which raise and lower the rotors from transport to operation modes. The rotors are 8m in diameter and the maximum rotor rotation speed is 24 RPM.
