The energy transition, and offshore wind power in particular, are hot topics today. Can you tell us about Bouygues Travaux Publics' expertise in this area?
Audrey Goulven (AG) / Bouygues Travaux Publics is a committed player in the energy transition, researching and rolling out innovative low-carbon solutions in the construction and public works sector, and especially the energy sector.

We use our skills as a designer-builder to support major industrial companies and players in the field of renewable energies, in particular for the construction of new infrastructures dedicated to offshore wind farms or future energy islands. We draw on more than 20 years of recognised experience in large maritime infrastructure projects and major engineering structures (NRL, Monaco offshore extension, Tangiers, HS2, etc.), as well as complex major industrial projects such as EPRs (FA3, HPC) or the Chernobyl confinement arch. It is thanks to this know-how and expertise that we are able to propose an integrated EPCI (Engineering, Procurement, Construction and Installation) offer for both gravity foundation projects for land-based wind power (Fécamp) and floating wind farm projects, which are currently seen as the future of offshore wind power development. 
What are our references in this fast-evolving sector? Can you tell us about an emblematic project?
AG / We joined the offshore wind adventure in 2016 on the Floatgen project, for the construction of the first 2-MW floating offshore wind turbine foundation, which is currently producing electricity.

In addition, we are now building the 71 concrete gravity bases for the future Fécamp offshore wind farm, which will produce 500 MW. That’s more than the number of gravity foundations installed in Europe since 2010. This exceptional project perfectly illustrates our know-how as a designer-builder and our capacity to industrialise.
What is the outlook for this sector and the challenges facing Bouygues Travaux Publics in the future?
AG / In the context of the global climate emergency, the offshore wind power sector is helping to decarbonise our economy, and floating wind energy in particular is a fast-developing industry. Major growth prospects are expected: more than 250 GW of floating wind power in the world by 2050. In France alone, the Multi-Annual Energy Plan (PPE) aims to build 10 GW of offshore wind capacity by 2035.

The major challenge facing the offshore wind energy sector, and one in which Bouygues Travaux Publics has a real role to play, is the industrial scale-up of these infrastructures to the commercial farm scale, with a large number of units and a reduced LCOE (levelised cost of energy). Our challenge is therefore to demonstrate our ability to industrialise the manufacture of these extraordinary floaters weighing more than 15,000 metric tons, as well as the competitiveness of our offer in terms of costs and delivery times, while respecting our commitments and our clients' expectations in terms of safety, quality and respect for the environment.

We look forward to seeing you at the Seanergy exhibition on 15 and 16 June in Le Havre for more information on the numerous development opportunities and challenges that await us!
