Navantia Seanergies, Navantia’s Green Energies division, has delivered its second substation jacket for Ocean Winds, this time for the forthcoming offshore wind farm at Dieppe Le Tréport in France. The jacket departed from the south basin of the Puerto Real shipyard, bound for its destination on France’s Atlantic coast.
The structure – almost 54 metres tall and weighing approximately 1,900 tonnes – was fully fabricated at the Puerto Real facility and was loaded out on Tuesday 13 May. Since then, adjustment and mooring operations have been carried out to prepare it for transport.
A year ago, Navantia Seanergies delivered to Ocean Winds a jacket with similar characteristics, also built at Puerto Real, which is now installed at the Îles d’Yeu et Noirmoutier offshore wind farm in France.
These jackets, constructed in Puerto Real, form part of the collaboration between Navantia Seanergies and Ocean Winds, a Madrid-based offshore wind company established as a joint venture between EDPR and ENGIE. Under this partnership, a capacity-reservation agreement was signed for the manufacture of components destined for future international offshore wind farms, including floating structures for forthcoming projects in Spain, Portugal and elsewhere in Europe.
A few days ago, the five-year operational anniversary of WindFloat, the Iberian Peninsula’s first floating project built at Navantia Seanergies’ Fene facilities, was celebrated. In 2023, Ocean Winds awarded the Navantia Seanergies-Windar consortium its first XXL monopile project – 14 units for the Moray West wind farm in the United Kingdom, already delivered – as well as the 62 turbine jackets currently under construction at Fene for the Dieppe Le Tréport project in France.

The Puerto Real shipyard now boasts a new flat-panel fabrication workshop, equipped with the latest welding technologies and a very high degree of automation – an investment that enhances its competitiveness in both naval and green energy sectors, particularly for floating structures.
The shipyard also hosts one of the company’s Green Energies Centre of Excellence (CoEx) hubs, which is vital for technological development under an open and collaborative model, and will be an essential lever for meeting Navantia Seanergies’ challenges not only in offshore wind but also in green hydrogen.
