France's first offshore wind turbine and BW Ideol's first demonstrator

Floatgen

IN OPERATION SINCE 2018


BW Ideol's first floater in operation

Built around a European consortium of 7 partners, Floatgen is a 2MW floating wind turbine demonstrator installed off the coast of Le Croisic on the offshore experimentation site of the Ecole Centrale de Nantes (SEM-REV). This project is being supported by the European Union as part of the FP7 programme.  Floatgen is France's first offshore wind turbine. 5 000 inhabitants are supplied with its electricity.

INNOVATION AT ALL LEVELS

  • BW Ideol’s patented Damping Pool ® floating foundation (36 square meters, draught of 7.5 meters), the world’s first floating barge designed for offshore wind
  • Innovate concrete and construction methods developed by Bouygues Travaux Publics
  • An international offshore facility operated by Centrale Nantes, SEM-REV, the first European multiple MRE technology sea site connected to the grid
  • 6 synthetic fiber (nylon) mooring lines, a world first for a permanent mooring system of this size

THE HIGHEST LOCAL CONTENT OF ANY FLOATING WIND TURBINE

In comparison to other steel floating foundations, which are imported from abroad, the use of concrete for BW Ideol's floating foundation allows the construction to be located as close as possible to the deployment site. Construction at the Saint-Nazaire port was therefore a natural and optimal solution and has created a lot of local content. Additionally, the mooring system was manufactured by LeBéon Manufacturing in Brittany. For the majority of all other components or logistical activities, the Floatgen partners have also opted for suppliers within the Saint-Nazaire region.

70 direct jobs created at the height of the project for the floating foundation construction in Saint-Nazaire, 20M€ in orders placed with French suppliers, 80% of Tier 1 suppliers are French  

BW IDEOL'S SCOPE OF WORK 

As project coordinator, BW Ideol is responsible for the design and engineering of the foundation as well as the subsequent construction, installation and operation & maintenance of the demonstrator equipped with a 2MW wind turbine off the coast of Le Croisic.  

SCHEDULE 

  • Construction at Saint-Nazaire harbour : 2016-2017
  • Inauguration and baptism : 13rd October 2017
  • Commissioning : mid-2018

PERSPECTIVES 

As the first demonstration unit for BW Ideol's floating technology, it has provided, and will continue to provide, the consortium partners with an unparalleled experience, particularly in terms of construction methods, deployment, and operation, in addition to its value as a showcase model for future export.

FIRST OPERATIONAL RESULTS

After exceeding expectations in 2019, the Floatgen wind turbine sets a new record in 2020 by producing 6.8 GWh, for a total of 12.8 GWh in two years. Moreover, a new capacity factor record was reached in February 2020 with more than 66%. The wind turbine faced very challenging weather conditions, with maximum wave heights of nearly 11 meters in February 2020. The excellent performance and seakeeping performance of BW Ideol's patented Damping Pool® technology are thus once again confirmed.TO FIND OUT MORE ABOUT THE PROJECT, VISIT THE DEDICATED WEBSITE

Ardesier BW Ideol

Work starts on Ardersier Port transformation

Work starts on £20 million capital dredge to reopen the port.
• Plans include:
o A dedicated 34ha floating wind manufacturing hub for concrete foundations in exclusive partnership with BW Ideol
o An oil rig decommissioning facility
o A £300 million ‘green steel’ mill, the UK’s first new steelworks in 50 years
o A concrete production plant
• This will create Europe’s first fully circular Energy Transition Facility which will:
o Recycle dredged sand as aggregate for concrete production
o Recycle steel from decommissioned oil rigs as reinforcement for concrete floating wind foundations
o Generate energy from waste
o Power a steel mill with green power from offshore wind
o Deliver 100 percent UK content
o Create thousands of jobs by 2030
