19-21 May, 2026 | Nantes - France Seanergy 2026


In France momentum is building again, new tenders are being launched, the AO10 offshore wind tender is taking shape, and national ambitions are becoming clearer through under the National Energy Strategy (PPE3), with nearly 18 GW of offshore wind targeted by 2035 and, for the first time, a commercial-scale objective for tidal energy. As the country also approaches major political milestones in 2027, maintaining clarity, stability and long-term commitment will be essential to secure investor confidence and accelerate project delivery.

At this decisive moment, Seanergy brings together the entire ecosystem to turn momentum into action: connecting stakeholders, fostering dialogue, and, as a multi-technology and European event,it also highlights the diversity and strength of our sector, as well as the strong synergies that connect technologies and the actors across all these value chains, from fixed and floating offshore wind totidal, wave and emerging marine energies. As Seanergy marked its 10th edition, it reflected more than a decade of Bluesign’s team commitment to promoting and supporting the development of offshore renewable energy sector around Europe.

17-18 June, 2025 | Paris - France Seanergy 2025


“Seanergy 2025 has shown that our ecosystem is ready to turn momentum into action. By gathering such a diverse range of stakeholders, experiences, and innovations, the event highlighted the ability of offshore renewables to generate concrete synergies for sustainable growth, not only in France but across Europe. The commitment and collective energy we witnessed confirm that, together, we have the capacity to meet today’s challenges and accelerate the deployment of the sector as a key pillar of the energy transition.”

26-28 June, 2024 | Nantes & Saint-Nazaire, Pays de la Loire - France Seanergy 2024


“In an unprecedented political context, the 2024 edition of Seanergy demonstrated the motivation and commitment of industry players, who must redouble their efforts to pursue their ambitious development. The density and diversity of the participants and the quality of the discussions once again confirmed that this industry, which has been growing steadily for over 10 years, is essential to the energy transition. It makes a significant contribution to decarbonized electricity, which has a significant impact on Europeans’ purchasing power. » Sabrina Pedrosa Peseux, CEO of Bluesign, organizer of Seanergy

Exhibition

20-22 June, 2023 | Paris- France Seanergy 2023


“The Parisian edition of Seanergy was a great success, welcoming nearly 4,000 participants and 200 exhibitors. The topics addressed, both in the exhibition and during talks and panel discussions, were strengthened with hydrogen, floating solar energy, digital technology and drones, as well as the challenges linked to training and employment in this sector. Today, Seanergy is helping to make France one of the world’s leading regions for offshore renewable energies, in a global context of climate crisis and energy sovereignty. » Sabrina Pedrosa Peseux, CEO of Bluesign, organizer of Seanergy

Exhibition

15-16 June, 2022 | Le Havre, Normandy - France Seanergy 2022


« In line with the strong global dynamics, the 2050 strategy published by the European Commission sets a target of 300 GW for offshore wind power and 40 GW for tidal and wave power. Given its potential, France can play a full part in this, to the benefit of the positioning of its players and its energy transition. The recent announcements of the Government, aiming at 40 GW installed in service by 2050, with the construction of 50 offshore wind farms and 20,000 jobs expected for the industry by 2035, lead to this direction, making France one of the first territories in the world for marine energy. In this context, our 2023 edition in Paris, a true global hub, will facilitate the participation of a very large panel of economic and political decision-makers, to reflect together on the growth that is taking place for the sector, while allowing us to take stock of the issues specific to each region, in a collective and concerted manner. In the continuity of this exceptional 2023 edition, the 2024 edition will mark our return to the region, close to the job pools, factories and projects, to rediscover the dynamics of the Pays de la Loire, a pioneering destination and a true European driving force for the development of marine renewable energies. » Marc Lafosse, Former President of Bluesign, organizer of Seanergy
