NAUTILUS FLOATING SOLUTIONS SOCIEDAD LIMITADA

Their core work

Nautilus is a Spanish engineering SME that designs floating substructure platforms for offshore wind turbines deployed in deep water — typically at depths exceeding 50 metres where fixed-bottom foundations are not technically or economically feasible. Their core work involves solving the structural, hydrodynamic, and mooring challenges of keeping large-capacity wind turbines (10MW class) stable in open-ocean conditions. Based in Bizkaia in the Basque Country, a region with deep roots in maritime and offshore industrial engineering, they sit at the intersection of naval architecture and wind energy. In H2020 they contributed both as a specialist partner in a major European qualification programme and as the lead on their own proprietary platform concept developed under the SME Instrument.

What they specialise in

How they've shifted over time

Both H2020 projects date to the same narrow 2015–2016 window, so a long-term keyword-driven evolution cannot be traced from the available data. What can be observed is a progression in autonomy: Nautilus entered H2020 as a consortium participant in LIFES 50plus, contributing specialist knowledge within a large multi-partner research effort, and almost simultaneously secured SME Instrument Phase 1 funding as coordinator of FLOW — their own proprietary floating platform concept. This arc, from contributing partner to independent technology developer within a single year, suggests a company that was rapidly building confidence in its own IP alongside collaborative R&D experience.

Nautilus appears to be on a trajectory toward independent technology ownership, having moved from consortium partner to SME coordinator within one funding cycle — a strong signal they were building proprietary floating platform IP rather than remaining a pure research contributor.

How they like to work

Nautilus has experience in both directions: as a specialist contributor inside a large multi-partner RIA consortium (LIFES 50plus, 15 partners) and as the coordinator of their own focused SME Instrument project. The combination suggests they can integrate into complex consortia where their niche platform expertise is needed, but they are equally capable of driving a focused innovation project independently. For a potential partner, this means Nautilus is unlikely to be a passive participant — they bring a defined technical asset and can manage deliverables on their own work package.

Nautilus has worked with 15 unique consortium partners spread across 7 countries, with most of that network built through the large LIFES 50plus consortium which drew together major European offshore wind research centres, universities, and industrial players. Their geographic network is genuinely European rather than Iberian-only.

What sets them apart

Nautilus occupies an extremely specific niche — floating platform substructure design for large-scale offshore wind in deep water — that very few SMEs in Europe can credibly claim. While large OEMs and research institutes also work in this space, an SME with hands-on platform design IP and direct experience qualifying structures for 10MW turbines brings agility and focus that larger partners often cannot. Their Basque Country base also gives them proximity to one of Europe's strongest offshore and heavy maritime industrial clusters, with established supply chains and testing infrastructure.

Highlights from their portfolio

• LIFES 50plus
  One of the flagship European H2020 projects for qualifying floating substructures for next-generation 10MW wind turbines in deep water — participation places Nautilus among the core technical contributors to Europe's floating offshore wind roadmap.
• FLOW
  Nautilus coordinated this SME Instrument Phase 1 project, demonstrating independent ownership of a proprietary deep-water floating platform concept rather than relying solely on collaborative R&D.
