FLAGSHIP is a Horizon 2020 project that aims to reduce the Levelized Cost of Energy (LCOE) for floating offshore wind to the range 40-60 €/MWh by 2030.

The initiative will develop and fabricate the first 10 MW Floating Offshore Wind Turbine (FOWT) assembled on a floating semi-submersible concrete structure in the Norwegian North Sea.

This demonstration project will manage a 25 million euros funding during its 4 years duration, aimed at optimizing floating offshore wind towards commercialization.

The initiative kicked off the 1st of September of 2020 and it will be coordinated by Iberdrola until its ending in 2024.

The project will build a robust and innovative semi-submersible concrete floating platform that includes an easy-to-install anchorage design, innovative mooring designs and configurations, as well as new cable designs with optimized installation and life management procedures.

To address these challenges, an international consortium has been created including companies and institutions form 5 different countries: Spain, Norway, France, Denmark and Germany.

This project is located in the harsh conditions of the North Sea and will be the starting point for large-scale of 500+MW future commercial FOW farms, ensuring its feasibility to other specific locations in the Atlantic Ocean, Mediterranean and Baltic seas.

The asset will be installed at the Marine Energy Test Centre (MET), as the owner of the test site area located in the Norwegian North Sea, and the knowledge generated by FLAGSHIP and the results of the demonstrative scenarios will be crucial for the industrialisation of floating offshore wind farms all over the world.


The main objective of the FLAGSHIP project is to validate and demonstrate an innovative cost-effective Floating Offshore Wind Turbine (FOWT) to ensure imminent LCOE reduction in the range 40-60€/MWh. This aim will be addressed with a set of specific goals:

Specific objectives


FLAGSHIP project will achieve its objectives based on the following principles:

  • Cost and environmentally effectiveness
  • Maintenance-free concept for floating platform and minimum O&M requirements for other components
  • Maximum efficiency and scalability potential proving a solution for a 10+ MW turbine, establishing the requirements for the scalability for 15-20 MW

The initiative’s methodology will be rolled-out in a 4-step process:

1- To adapt the design of the OO’s validated concept of the floating platform as the starting point of the overall design.

2- To start activities to move from one single unit to wind farm scale, in order to ensure that the design proposed and demonstrated is suitable for mass production.

3- To carry out the execution activities at single unit level, as well as the engineering activities of the required operations both in the construction site and shelter waters (onshore/inshore) and for transport and installation (offshore)

4- To study the potential replicability in other locations and the future demand of the solution.
