The AK series turbines are commercial scale Horizontal Axis Turbines designed for open ocean deployment in the harshest environments on the planet. AK turbines feature a unique twin rotor set with fixed pitch blades eliminating the requirement for sub-sea nacelle rotation to improve operational reliability. AK turbines are rated at 2.6m/s and are available in 1MW and 2MW systems. The AK-1000, the first of the AK series, is currently being built for deployment in summer 2010.
