KTA1 Floating platform concept.
The elements that integrate the floater solution at unit scale will be described under the this KTA. The floating platform design for FLAGSHIP Project is a simple, robust and cost-effective semisubmersible concrete structure for floating offshore wind. It has a central tower for wind turbine connection and 3 symmetrical pontoons that connect with one column each.
The pontoons remain buoyant during the inshore assembly phase but filled with water and connected to sea during operation. The floating platform is fully designed in concrete, moving forward from steel or hybrid solutions currently used in existing floating demonstration projects, turning into the first 1:1 fully concrete semisubmersible platform demonstrated. It is designed to have a moderate draft in operation and very shallow minimum draft allowing for completion and testing while floating at quayside.
KTA2 Turbine and Control System.
This KTA will prove for the first time a large capacity wind turbine (MVOW) installation at 1:1 scale on a concrete-floater, allowing to demonstrate the feasibility of the floating platform to support this high rated turbine with optimised elements in the Transition Piece (TP) for the connection tower‐platform to facilitate assembly and reduce fatigue effect as well as the implementation of the required holistic combination of control methodologies.
