Energy from Ocean Currents
Hammerfest Strøm is developing technology and turn key projects for generating electricity from tidal currents
|
Main features:
|
Electricity is being produced in both directions of water flow. The nacelle is in fixed position while the turbine blades turn along its own axis.
Automatic control allow for unmanned operation and optimum energy output.
|
Tilted structure minimizes flow disturbances and hence vibrations and unfavourable dynamic effects.
Gravity based foundation allow for minimum installation resources and leaves the sea bottom in original condition when removed.
|
| Hammerfest Strøm’s prototype is delivering electrical power to the grid on a daily basis |
The prototype is the first grid connected device in world directly transforming energy from tidal streams into electrical power. The prototype is located in Kvalsundet outside Hammerfest, northern Norway. |

Operating principles
-
The water current is driving the turbine. The power is optimised by regulating the pitch of the turbine blades.
-
The power is converted to electricity in the nacelle (production module) The nacelle contains control system, gear box and generator.
-
The electrical power is transmitted onshore by means of a sub sea cable.
