HOVIK, Norway — DNV has provided Fred Olsen 1848 with a statement of feasibility (similar to an approval in principle) for its floating wind turbine concept, BRUNEL.
The structure, designed to support a 15-MW wind turbine, is a column stabilized unit with three columns connected by submerged horizontal pontoons. Its rotor-nacelle assembly is supported by two inclined towers meeting at a distance below the nacelle interface.
The structure will feature a single-point mooring through a turret to weathervane. According to DNV, the design allows for a modular approach, suitable for serial production.
With this first step in the certification process, DNV considers the BRUNEL concept feasible for further development.
