Engineering firm Eolink along with fifteen European renewable energy partners gathered in Brussels on the 18th January to kick-start the launch of the Black sea Floating Offshore Wind (BLOW) project. The EU-backed scheme aims to install a 5MW floating wind turbine in the Black Sea off the Bulgarian coast in a crucial step toward a future of sustainable energy solutions.

The project is one of three to be awarded by the European Commission’s Horizon Europe research and innovation programme last year, all aimed at sustainable energy solutions, with a grant agreement signed at the end of 2022. BLOW will use Eolink’s wholly unique floating offshore wind turbine design, and aims to engineer, manufacture and commission the 5MW unit by 2025 before rolling out large-scale deployment as part of a wider industrialisation process. Eolink’s patented concept addresses ongoing industry issues by spreading the turbine’s stresses using four steel masts instead of one, offering a competitive weight-to-energy ratio that makes the overall structure more than 30% lighter.

Eolink’s CEO and Founder, former Renault engineer Marc Guyot, said: “The objective of this specific project is to demonstrate the competitiveness of floating offshore wind in lower-wind areas with the deployment of a large rotor diameter. Winning this award has allowed us to take one step further towards our ultimate goal: offering a viable energy source that is as low-carbon as possible.”

The sixteen European partners* include Spanish-based IREC and Acciona, the Turkish Offshore Wind Energy Association, German research organisation the Fraunhofer Institute, and the European Marine Energy Centre in Scotland. The unit will be connected to an existing gas platform operated by Petroceltic, a Bulgarian oil and gas company. GSP offshore, a Romanian offshore services operating company, will manufacture the unit in their shipyard in Constanta (Romania).

“The World Bank 2021 report indicates there is vast technical potential in South East Europe, with a staggering 166 GW of floating offshore energy in the Black Sea alone, which is the equivalent of five times the electricity consumption of Bulgaria and Romania. Through this project we hope to catalyse offshore development across the region, which already has ongoing fixed-bottom offshore wind projects in Romania,” added Eolink's Chief Commercial Officer, Alain Morry.

The kick-off meeting last week laid out a development plan that will see an initial phase of engineering, environmental and social impact assessment before entering the construction phase. The unit will be designed to operate with maximum efficiency in the Black Sea, including adapting it with a larger rotor so it can generate more energy in low-wind areas.

The project marks Eolink’s second deployment of its patented concept in Europe after the France Atlantic Project, which aims to be connected to the French government grid by 2024.

In the context of the Call for Expressions of Interest CORIMER 2022, EOLINK and its partners - EVERAXIS INDUSTRIES, France Énergies Marines, IFREMER, Université Gustave Eiffel, WINDGLAZ - have been designated winners of the call for projects "Technological bricks and pre-industrial demonstrators" initiated by ADEME in February 2022 ("AAP DEMO TASE"). 

The HT-20MW project is supported by the Pôle Mer Bretagne Atlantique and led by EOLINK. The project is about the engineering, manufacturing, demonstration and certification of a high-voltage (66 kV) watertight rotating mechanical and electrical connection fully immersed under 30 meters and maintenance-free for 10 years.The budget is 6.2 million euros and the project will start in early 2023 for a 3-year period.

HT-20MW is the first program of its kind to integrate an electrical collector manufacturer, EVERAXIS INDUSRIES. This is a real asset that will enable the development of a solution suitable for floating wind turbines to ensure the export of electricity produced by the turbine.

The demonstration will be applied to a 20 MW floating wind turbine developed according to the EOLINK pyramidal concept and lab tank tests will be carried out in IFREMER's facilities at its #Brest site. 

FRANCE ÉNERGIES MARINES will identify the failure modes of the dynamic electrical cables and propose a suitable in-service monitoring solution. The robustness of the latter will then be tested experimentally on specific aspects.

UNIVERSITÉ GUSTAVE EIFFEL is in charge of the design and execution of the fatigue tests of the synthetic anchorage line and the dynamic cables.

WINDGLAZ focuses on the definition of the global numerical model of the 20 MW wind turbine.

EOLINK, VALOREM & Ecole centrale de Nantes have received a €14.9m funding from the French funding programme “France 2030” by ADEME. 
 
The project includes the manufacturing and the commissioning of an innovative floating wind turbine developed by EOLINK. Thanks to this project, the floating wind turbines will gain maturity for commercialization. In particular, the innovative solution developed by EOLINK leads to a significant cost of energy reduction thanks to a 30% lighter floating structure.  The 5MW pre-commercial floating wind turbine will be commissioned in 2024 at the SEM-REV test site owned by Centrale Nantes.
 
Valorem is in charge of the turbine-float assembly and the Operation & Maintenance, Chantiers de l'Atlantique provides support regarding steel fabrication, while Eolink is the project designer and coordinator.
