• This concept consists of a floater connected to a ballast unit with a frame construction. Turbine and generator is mounted in the middle of this frame.
• The drag forces goes directly through the turbine, and this makes a cost effective solution possible.
• The weight of a 880 kW unit capable of producing 3,2 GWh a year is approximately 53 tons. (ex. concrete- and water-ballast)
• Investment cost is the most important cost element in renewable energy, and we expect prices comparable to land based wind from these units when employed on a industrial scale.
• With state of art polyester mooring lines it can be deployed in deep water where sea bed based units is not an option.

  Easy and cost efficient to deploy and retrieve 

• The units will be assembled on site.
• The frame construction will be bolted together on site
• Due to an integrated water ballast tank the unit can be floated horizontally and be launched and serviced in shallow waters.
• It can be deployed and retrieved from the site in its normal vertical position.
• The moorings will be preinstalled and the unit can quickly be connected to these. 
• The electrical grid connection cable goes out in the bottom of the ballast tank and from there to shore.

• The concept has been evaluated positively in a technical report by a well reputed marine technology company.
• With some minor adjustment this concept is expected to behave well in areas with occasional high waves as well as tidal currents
• It is recommended to stop electricity production in waves higher than 3,5 meter (significant height). 
• This occurs less than 10 % of the time in North Sea condition. In expected production this is taken into consideration.
• The turbine can be weather-vaned in order to reduce loads under such conditions.
