THE SEAWIND SOLUTION

SEAWIND TURBINE

The Seawind 6 turbine is an upwind two-bladed, variable speed wind turbine with a teetering hinge. Power production of the Seawind 6 is controlled by turning the turbine head into or out of the wind (yawing), rather than turning the blades around their axis (pitching). Seawind turbines eliminate pitch control – the major failure source of three-bladed wind turbines.
Seawind eliminates failure-prone components, utilises long-lasting components and integrates modular components that can be replaced quickly and easily to improve uptime. The Seawind solution will deliver an LCOE below €0.05 per kWh. Besides important cost reductions the design follows novel principles:

 

● Reduction of single-points-of-failure

● Designed for maintenance with removable parts

● Safe access by boat and helicopter

● Passive emergency stop system

● Hurricane horizontal parking

CONCRETE SUPPORT STRUCTURE

Seawind uses concrete foundations with steel towers. The gravity foundation is used for the demonstrator in Norway, engineered by Dr. Olav Olsen SA (Norway) for water depths of between 40 and 90 metres. Concrete is inexpensive and lasts a lifetime (up to 100 years). The concrete support structure is made at the pier, then completed with a nacelle and rotor at the pier. The entire system is towed out to the site and installed in a rapid one-shot operation.  The concrete foundation provides enough buoyancy to transport and install the floating system through ballasting and sinking.

 

● Longer lifespan for extended and higher investment returns

● Seawind has both fixed and floating solutions

● Fast and cost-effective installation of the complete offshore system

INDUSTRIAL ASSEMBLY LINE

The final step in achieving our ambitious low cost  levels is through industrializing the Seawind offshore Energy System. Seawind produces the structures onshore, completes the system with the nacelle and rotor and installs the complete, mounted systems. This saves precious installation time and cost.

 

● Assembly line process for the offshore wind energy market

● Reduced build-out time of less than one year

● No special and costly installation vessels necessary

● Complete system solution approach that reduces risks and enhances capital recovery

WATCH THE SEAWIND CHANNEL

Offshore wind is a renewable energy source with significant undeveloped potential due to the high costs of the current offshore wind technology and the limited initial availability of onshore sites
