Flex2power consists of three concept models:

S1 – single floater with installed capacity 11,2MW

Q1 – quadrature with installed capacity 65MW

P1 – park level with several quadrature installations. 260MW with four Q1


Flex2power S1 substructure overall dimension:

136,6 x 136,6 x 52,8m (32,8m above sea level)

Substructure weight: 7500 tons (incl 4000 tons on concrete foundation)

Water depths: 60 – 1500m

Mooring: 4 anchor and mooring lines


Demonstrator of wind, wave and sun energy installation

5 MW installed wind turbine capacity

6 MW installed wave energy capacity

0,2 MW installed sun energy capacity


Complete installation close to fabrication yard inshore.

Low cost on production, towing, installation, operation and maintenance (Low LCoE)

Excellent stability in High Waves and Heavy Wind. Concrete foundation 20m below sea level for floater damping, stability and strength.

Extended height above sea and stability improve turbine, wave energy transformers and solar panel efficiency and lifetime

Area-efficiency. Flex2power park level configuration will occupy only  16% off surface area compared to other offshore concepts measured in MW/km2

Option to install helideck and transformation module on substructure.

Feasibility for extension of concept unit.
