Norwegian Tidal Solutions has developed a submerged tidal power plant for converting tidal water and ocean currents into electrical energy. The tidal power plant is patented in Norway and is patent pending in Canada, China, South Korea, Australia, New Zealand, USA and EP. The company is looking towards the international market.

The companys tidal power plant can consist of a turbine house of concrete measuring 5x5x6m. Concrete is a low cost building material which increases the lifetime of the power plant and also increases weight for anchoring to the sea bed.
The turbine house is internally shaped like a Venturi duct and by stacking 16 turbine houses in a 4x4 grid we can achieve a 215% increase in energy production.
A skid connects the tidal turbine to the turbine house. The turbine can slide into, out of or within the turbine house to regulate the speed of water flowing through the turbine. The Venturi principal makes it possible to attain operation water speeds for a large part of the tidal water wave than for in stream turbines. Therefor full energy production can be achieved already from an early point of the tidal water wave.
The technology also gives us full energy production in spring and storm flow. The turbine can slide out of the Venturi duct to turn 180 degrees so that the turbine will meet the tidal water current in both directions for optimal turbine effect without the use of costly tiltable turbine blades. The turbine can be slid out of the turbine house to be changed out for service independently of the other turbines in the power plant. A high pressure jetting unit is mounted onto the turbines stern and connected via an automatic extendable arm which cleans the Venturi duct as the tidewater is turning. The turbines in the power plant can work independently of each other and even if some of the turbines malfunction, we will still maintain high energy production.
The tidal power plant is scalable as the turbine houses can be stacked side by side and above each other. The power plant is flexible as it can be designed in several different ways either fully automated or ROV operated and designed according to the particular tidal water current and customers requirements.
