Navantia Seanergies

What Navantia Seanergies does

Navantia Seanergies is the renewable energy division of Navantia, a Spanish state-owned shipbuilding and defence company ultimately controlled by SEPI (Sociedad Estatal de Participaciones Industriales). Headquartered in Madrid, the division designs, engineers, fabricates, and delivers large-scale offshore wind structures — including substation jackets (up to 1,700 tonnes and 62 metres), monopiles, transition pieces (~434 tonnes), and floating platforms — from four shipyard sites in Fene, Ferrol, Puerto Real, and Cartagena that collectively account for over 2.5 million square metres of industrial land with direct sea access. It also operates the COEX Green Energies Center of Excellence across three of those sites as an open-innovation hub with customers, SMEs, universities, and technology centres.

The business serves major international offshore wind developers and utilities through project-based, long-term contracts. Documented customers include Ørsted (Revolution wind farm, US), Iberdrola/Scottish Power (East Anglia 1, Wikinger), and the Ocean Winds/LEMS consortium (Iles d'Yeu et Noirmoutier, Dieppe Le Tréport), with Aibel as a one-off oil & gas client. Manufacturing is differentiated by the proprietary Knot Welding Robot — described as the only robot with proven commercial experience welding offshore jacket knots — and by high-capacity lifting facilities and robotic workshops that enable structures of record scale. The division also leverages over fifteen years of hydrogen technology originally developed for the S80 submarine's AIP propulsion system to offer green hydrogen production infrastructure for industrial clusters.

Revenue is generated through one-time project hardware sales for offshore wind structures, recurring operations and maintenance services for installed wind farms, and emerging green hydrogen infrastructure deployments. Go-to-market is direct enterprise and B2G sales to a narrow set of large counterparties, supplemented by industry association presence (WindEurope Management Committee), talent partnerships (UPM Cátedra Romero Landa), and innovation collaboration through COEX. Geographic reach is stated as global, with documented projects across Europe (UK, France), the Americas (US), and references to Asia and Australia. Revenue, headcount, and pricing are not publicly disclosed at the division level.

Revenue model

1. Offshore Wind Structure Manufacturing: Design, engineering, and fabrication of offshore wind structures on a project-by-project basis. Revenue is generated through long-term contracts with wind farm developers for the supply of jackets, monopiles, transition pieces, substation platforms, and floating foundations. Projects span from design through production and sometimes include assembly and delivery.
2. Offshore Operations and Maintenance Services: Operation and maintenance services for offshore wind farms applying naval sector expertise. Services are provided to wind farm operators post-construction, typically through service contracts.
3. Green Hydrogen Solutions: Development and deployment of green hydrogen production infrastructure for industrial clusters, leveraging hydrogen technology expertise from the defense sector.

Core offering

Navantia Seanergies designs, engineers, fabricates and delivers offshore wind structures including AC substations (up to 714 MW, transforming 66 kV to 220 kV), fixed and floating jacket foundations (up to 1,700 tonnes, 62 metres), monopiles and transition pieces (~434 tonnes), plus green hydrogen production technology. The company also provides operations and maintenance services for offshore wind farms, applying expertise from its parent Navantia's naval shipbuilding heritage.

Product overview

Navantia Seanergies is a global partner in green energies, operating as a division of Navantia. The company's product portfolio centers on offshore wind energy infrastructure manufacturing, comprising offshore wind substations (AC substations for wind farms up to 714 MW), jacket foundations (fixed and floating, up to 1,700 tonnes), monopiles, and transition pieces (MSF modules connecting foundations to substations, approximately 434 tonnes each). Complementing the wind energy offerings is a green hydrogen technology division with over 15 years of experience (originating from defense sector AIP technology for S80 submarines), now applied to industrial hydrogen production. The COEX Green Energies Centre of Excellence provides an innovation ecosystem spanning three Spanish sites (Fene, Puerto Real, Cartagena) supporting collaborative R&D with customers, supply chain partners, universities, and technology centres. Additionally, the company offers offshore wind farm operation and maintenance services leveraging naval sector expertise.
