Beridi's Wind Floater: What the EIC Accelerator Paid For

Beridi Maritime, a 2018 spin-out of the Madrid port engineering firm Berenguer Ingenieros, designs TRIWIND, a hollow concrete platform meant to carry offshore wind turbines in water too deep for fixed foundations. In the EIC Accelerator pilot's Green Deal cut-off of 19 May 2020 it was selected for blended finance, a grant plus EIC equity, for a project called ARCHIME3, according to the European Commission's list of selected companies, which names Beridi as the project's only company. CORDIS records an EU contribution of €2,442,043.28 towards a total cost of €3,488,633.25, from 1 January 2021 to 28 February 2025.

The company described ARCHIME3 in February 2022 as "designed to facilitate the installation of a real-scale TRIWIND prototype", and planned a 1.5 MW unit at the PLOCAN ocean test site off Gran Canaria, according to its own project update and a later post on the finished engineering. No construction of that platform was announced. When the project closed, the largest piece of hardware was a partial, full-scale section of a 22 MW floater, nearly seven metres tall, cast on land in Lugo to test the construction method, according to Beridi.

Where Beridi Stands Now

Beridi is a going company with a small footprint. The Spanish register lists it as active, with annual accounts deposited for 2020 to 2024, a share capital of €11,972 and annual sales below €500,000, according to Empresia, which reprints the company's entries in the official gazette BORME. Infoempresa puts its staff at 1 to 9 people. The latest register entry, dated 19 August 2026 and published on 27 August 2026, moved the registered office from Calle Pan de Azúcar in Madrid to the Edificio Tandem on Paseo Miramón in San Sebastián, according to both sites. Beridi's website still gives a Madrid address, and its most recent post, from 17 October 2025, argues that EU steel tariffs favour concrete floaters such as TRIWIND.

The register shows no capital increase after March 2021, when the share capital went from €4,006 to €11,972 in two steps, according to Empresia. Beyond the address change, it shows only changes among directors and attorneys named Berenguer: José Berenguer Cobián was sole director from April 2020 until December 2022, when Fernando José Berenguer Rodríguez de la Flor took over, and Javier Berenguer Cobián became an attorney of the company in December 2021. The company's team page names Javier Berenguer as chief executive and Ignacio Cobián, an architect, as chief technology officer and "the inventor of the technology"; Merca2 also named Javier Berenguer as chief executive in 2021.

The Technology: A Concrete Hull Built Like a Silo

Most current floating platform designs use steel as their main material, Beridi notes in an October 2025 post. TRIWIND is a monolithic concrete structure divided into internal cells, some of them open to the sea, which provide buoyancy and damping and regulate ballast without pumps, according to Beridi's technology page. The turbine sits in the centre and can be mounted in port and towed out with the platform. The hull is meant to be cast by slip-forming, which Beridi calls a proven method in the maritime and offshore sectors, in which concrete is poured continuously into a mould that climbs as the concrete sets. Beridi says its design needs no post-tensioning tendons, which it argues makes slip-forming simpler, and that each platform can be built in 28 days.

The cost claims are the company's own and have grown over time. In 2021 Beridi told Merca2 that concrete saved up to 50% on the platform; its final CORDIS report claims a levelised cost of energy up to 50% lower than competing concrete designs and nearly 60% lower than steel ones "in a mature market"; its October 2025 post says TRIWIND cuts capital costs by about 60% against steel platforms. No independent cost assessment of TRIWIND has been published, and no platform has operated at sea, so none of these figures can be checked against a working unit.

The idea predates Beridi. In 2017 Berenguer Ingenieros received €50,000 from the Horizon 2020 SME Instrument Phase 1 for a feasibility study of TRIWIND, a "3-tower maritime structure" based on Spanish patent application P201631043, according to CORDIS. The ARCHIME3 results page lists five patent applications filed by Beridi in 2018 and 2019. Beridi reported patents granted in the United States and Japan in May 2024 and in South Korea in 2025.

What ARCHIME3 Promised, and What It Delivered

The CORDIS objective written at the time of the award is a business plan more than a work plan: it projected that by 2026 Beridi would have "installed our first wind farm (400 MW)", with €44 million of cumulative turnover, €20 million of cumulative EBITDA and a company value close to €240 million, "a x13 ROI for the investment (2.4 M Grant + 4.8 M equity) requested to the EIC". None of that has happened: no TRIWIND wind farm, customer order or site lease has been announced by Beridi or reported by the press sources cited here.

The physical demonstrator was the project's central deliverable in Beridi's own telling. In May 2022 the company said the detailed engineering of the 1.5 MW platform for PLOCAN was complete and that execution and installation were "programmed for 2023"; in July 2022 it opened a tender among shortlisted contractors for "the construction, installation, operation, maintenance and decommissioning" of the unit, aiming to start works in early 2023. No contract award or construction at sea was announced afterwards. The final CORDIS report, covering January 2022 to February 2025, lists four key objectives, none of which is a sea prototype: proving the design by calculation and tank testing, an Approval in Principle, a Basic Design certification and a full-scale construction mock-up. The data provider TGS 4C, which lists the 0.5 MW "Archime3" entry off Gran Canaria with Beridi as owner, records that "the project concluded at the end of the funding period, 28 February 2025", on its project page. Why the demonstrator was dropped has not been explained publicly.

What was done is documented. Tank tests at the IHCantabria institute of the Universidad de Cantabria simulated the worst expected waves, wind and currents at the planned site, Energías Renovables reported in November 2021, and a second campaign in 2024 tested a hexagonal version for 22 MW turbines under Gulf of Maine conditions, according to Beridi. Bureau Veritas granted an Approval in Principle in October 2022, the company announced, and the CORDIS report states it was for a 15 MW turbine. The report also claims "Basic Engineering Design (BED) Certification for a 22 MW turbine"; Beridi's website announced in July 2024 only that the assessment had begun, and no completion announcement from Beridi or Bureau Veritas could be found.

The Lugo mock-up was a triangular prism with three wall junctions, built with local partners Costanor, Bygging-Uddemann, Master Builders Solutions and GalaiControl over about six weeks, according to Beridi. It tests whether the hull can be cast as claimed, which matters for the cost case, but it does not float and carries no turbine.

The Money

The grant was shared within the group. Of the €2.44 million EU contribution, Beridi received €1,937,605.78 and its parent Berenguer Ingenieros, a linked third party that did not sign the grant agreement, received €504,437.50, according to CORDIS. In 2021 the company said ARCHIME3 had raised €2.65 million in European and national public funding and that the European Investment Bank had committed a further €4.8 million, as reported by Energías Renovables; €4.8 million is the equity Beridi had requested from the EIC, per CORDIS, and the EIB acted as investment adviser to the EIC Fund and ran its due diligence, according to the European Commission.

The EIC equity did arrive in some form. Beridi Maritime, S.L. is listed among the EIC Fund invested companies, with its own portfolio page, but neither page gives an amount or a date. In December 2023 Beridi announced "a new injection of capital from the European Investment Bank" structured as a convertible loan, with two strategic partners to join "in the coming months" and an equity round "expected to close during 2024", according to its announcement. Whether that loan is the EIC Fund's investment is not stated. No closing of the 2024 round has been announced, the partners have not been named, and the register shows no capital increase since 2021, according to Empresia.

Beridi has also drawn Spanish public money. It completed a CDTI NEOTEC grant, reference SNEO-20201322, for a variant called Triwind 3C in 2023, according to Beridi. It leads ECOFLOWIN, a three-year project of more than €760,000 with the CTC technology centre under the State Research Agency's 2023 public-private call, which aims to cut the platform's carbon footprint by more than 30%, Smartgrids Info reported in February 2025. In 2024 the group won funding for HYDROSTORE, a green hydrogen storage project on floating platforms led by Berenguer Ingenieros under Spain's PERTE ERHA programme, according to Beridi. CORDIS lists no EU project for Beridi other than ARCHIME3.

Why It Matters for Europe

The EU's offshore renewable energy strategy of November 2020 targets at least 60 GW of offshore wind by 2030 and 300 GW by 2050, according to the European Commission. Beridi's own CORDIS report estimates that shallow waters cap fixed-bottom capacity at 112 GW, which is why floating platforms matter for the 2050 goal, and Spain's government aims for up to 3 GW of offshore wind by 2030, Merca2 reported. A concrete floater cast in local ports from local materials would rely less on imported steel, the argument Beridi made in its October 2025 post. Spain also has competing designs: Merca2 named EnerOcean in the Canary Islands and Saitec in Cantabria as other Spanish floating prototypes in 2021.

The Verdict

A grant is meant to fund development, and Beridi used it to advance TRIWIND from a feasibility study to a design that, by its own report, has Basic Design certification and a tested construction method. But the step that would prove the concept, a platform carrying a turbine in open water, moved from 2023 to no date at all, while the company's register entries show a business that has not grown beyond a handful of staff. Beridi and the EIC have not been asked for comment for this article, which is based on public records and published statements linked throughout.
