Minesto orders turbine prototype from Schottel Hydro

Marine energy technology company Minesto, together with German tidal turbine manufacturer Schottel Hydro, has completed the turbine design of Minesto’s Deep Green tidal power plant
Minesto orders turbine prototype from Schottel Hydro

The Swedish company has now placed an order for a prototype of the turbine with delivery expected in early 2017. The Power Take Off system will be the first result of the strategic technology partnership between the two companies which began in December 2015. During 2016-17, Schottel Hydro will deliver a customised turbine solution which will optimally fit the requirements of the Deep Green power plant.

“We are very pleased to have completed and verified the turbine design for Deep Green” said Martin Edlund, CEO of Minesto. “Compared with the first generation Deep Green, the turbine's performance has been improved by about 10 percent. The partnership with Schottel Hydro works perfectly fine, just as expected. It is important for us that they have taken overall responsibility for developing this important subsystem.”

The development of the turbine has, among other things, resulted in a larger rotor diameter, the rotor now having five blades instead of three. The design has also been established and verified through model tests by Germany’s Schiffbau Versuchsanstalt in Potsdam.

Martin Baldus, Technical Director at Schottel Hydro, added that the model scale tests prove the turbines performance and cavitation behavior to be advantageous compared to previous designs and that the integration of Schottel Hydro’s scope of supply into the Minesto kite system works out really well. The development of Deep Green will now enter its next phase entailing completion of the design of the full-scale system. Schottel Hydro will move ahead with manufacturing the prototype and conducting the factory acceptance test. Systems and components will be assembled into a full-scale demonstrator which will subsequently undergo final functionality testing. The full scale Deep Green system will then be deployed as part of offshore facility in Wales in 2017.
