Schottel Hydro’s Pitch Hub for MeyGen Tidal Turbine

SCHOTTEL HYDRO will manufacture and deliver the variable pitch hub for the AR1500 turbine for Phase 1a of the MeyGen tidal energy project under contract to Lockheed Martin.

The MeyGen Phase 1a AR1500, a 1.5 MW seabed mounted turbine, is being designed and delivered by Atlantis Resources and Lockheed Martin. The MeyGen project intends to generate up to 398 MW with offshore tidal turbines by the early 2020s.

The AR1500 will have an approximate rotor diameter of 18 meters, asking for a strong and robust hub to accommodate the essential pitch mechanism. SCHOTTEL HYDRO provides this hub with a housing diameter of 2.4 meters and a weight of approximately 35 tons. The active pitch mechanism inside adjusts the rotor blades to the flow and thus adds to the optimum alignment of the full yaw turbine.

“Taking part in this project is a great honor for us and our work,” says Jens-Henning Bernstein, project manager at SCHOTTEL HYDRO. “For this project we especially build on the success of the turbine shaft, hub and pitch mechanism including hydraulics and controls we provided to the first Hammerfest HS1000 turbine in 2011.”

SCHOTTEL HYDRO will deliver the hub in early 2016, and the installation of the AR1500 is planned for later the same year.
