This industrial milestone, the result of a collaboration that dates back more than a decade, consolidates the Navantia Seanergies – Windar Renovables alliance as one of the major manufacturers of foundations for offshore wind turbines on the continent, with a presence in projects in Germany, Denmark, France and the United Kingdom.
A milestone: 200 jackets manufactured in Fene for offshore wind.
The new structure corresponds to a fixed jacket foundation This unit is destined for the Dieppe le Tréport offshore wind farm, developed by LEMS, a temporary joint venture in which Ocean Winds is the majority partner. With this addition, the cumulative production in Fene reaches 200 units for offshore wind projects in Europe.
Navantia Seanergies and Windar Renovables emphasize that this achievement is the result of a journey that began with the first joint offshore wind contractThe collaboration began when both companies undertook the manufacture of 29 jackets for the Wikinger wind farm, developed by Iberdrola in German waters of the Baltic Sea. Since that initial order, the partnership has expanded with new projects and subsequent contracts.
Among the two hundred foundations that emerge from Fene are structures installed in some of the most representative offshore wind farms from Europe, which has allowed the Spanish alliance to gain weight in a market marked by strong international competition.
As both companies emphasize, reaching 200 jackets demonstrates a consolidated industrial capacityMature production processes and a technical specialization that has grown in tandem with the demand for offshore wind energy on the continent.
From Wikinger to Dieppe le Tréport: more than a decade of experience
The history of this cooperation dates back more than ten years, when Navantia and Windar joined forces for the project Wikinger, in Germanywhere they manufactured 29 jackets for Iberdrola. That first contract marked the starting point of a stable relationship that has resulted in an increasingly broad portfolio of projects in the European offshore sector.
After Wikinger, agreements were reached for parks such as Moray East and East Anglia One In the United Kingdom, these projects have been key to strengthening the alliance's presence in the British market. They have become benchmarks for offshore wind in Northern Europe and have required a high level of industrial and logistical coordination.
The activity has also extended to Denmark, with Nissum Bredning, a pioneering development that combined innovative technologies, already in France, with the park St. BrieucDieppe le Tréport has now been added to this list. All these facilities have been completing the list of destinations where the foundations designed and built in Fene are in operation.
With the Dieppe le Tréport projectThe project, which will be located in the waters of the English Channel off the French coast, strengthens the alliance's role in the French offshore wind market, one of the fastest growing in Europe in recent years.
80 additional jackets in the UK with Navantia UK
In addition to the production carried out in Spain, there are others 80 jackets built in the United Kingdom, in facilities that became part of Navantia UK in 2025. These factories, located in Methil (Scotland) and at the historic Harland & Wolff shipyard in Belfast, have allowed for the expansion of production capacity close to the main British projects.
The foundations produced at these centers have been primarily used for offshore wind farms such as Ormond, Beatrice and East Anglia One, helping the alliance consolidate its position in the UK offshore market, one of the most developed in the world in terms of installed capacity.
If we add the structures manufactured in Fene and in the British facilities, the figure reaches 280 jackets produced between Spain and the United KingdomAccording to Navantia Seanergies and Windar Renovables, this volume represents approximately half of all foundations of this type currently installed in Europe.
This relative weight places the alliance as one of the leading jacket manufacturers internationally, with the capacity to handle large-scale projects and meet the demanding schedules managed by offshore wind farm developers.
Fene, European reference center for offshore wind energy
The activity linked to the manufacture of these structures is mainly concentrated in the Fene shipyard, in A Coruñawhich the companies themselves describe as a true European benchmark in offshore wind. From these facilities, much of the engineering, manufacturing, assembly, and shipping work for the jackets is coordinated.
In Fene, the production of multi-leg foundations coexists with the manufacturing of monopiles and floating structures for offshore wind, which has allowed diversification of the offer and adaptation to the different types of projects being developed in European waters.
The shipyard is also preparing to take another step forward with its entry into the offshore electrical substation marketThis is a key component for evacuating the energy generated in offshore wind farms and connecting it to the onshore grid. This new line of business will further strengthen Fene's role as an industrial hub associated with the energy transition.
In addition to the purely industrial aspect, the consolidation of Fene as an offshore wind hub has an impact on the local and supply chain employment, by involving a large number of auxiliary companies and specialized suppliers in metal construction, logistics, engineering and services.
Navantia Seanergies – Windar Renovables Alliance and commitment to the energy transition
Navantia Seanergies is the division of Navantia focused on green energy and the offshore industryFocused on developing solutions for offshore wind farms and new applications such as hydrogen, and thanks to synergies with the other areas of the group, it offers comprehensive services ranging from foundations to substations.
For its part, Windar Renewables It has positioned itself as a global player in the field of clean energy, specializing in the manufacture of foundations and towers for both offshore and onshore wind power. The company has production facilities in countries such as Spain, India, Brazil, Mexico, and Poland.
The alliance between the two firms combines the Navantia's industrial capacity With Windar's experience in the design and manufacture of structures for wind turbines, we have created a competitive offering in a sector where the size of projects and the level of technical requirements are constantly growing.
With contracts signed in recent years for hundreds of millions of euros and a recurring stake in some of the Europe's most important offshore wind farmsThe Navantia-Windar collaboration has become one of the pillars of the Spanish strategy to gain a presence in the marine renewables value chain.
The achievement of the 200 jackets built in FeneThis, along with the 80 additional vessels manufactured in the United Kingdom, reflects the evolution of an industrial alliance that has gone from an initial contract in Germany to becoming a European benchmark for offshore wind power, reinforcing the role of Spain and its shipyards in the deployment of renewable energies at sea.
