What Bluefins does

Bluefins is a French marine technology company developing WaveDrive, an articulated hydrofoil auxiliary propulsion system attached to the stern of ocean-going vessels. The system harvests wave and swell-induced motion and converts it into forward propulsive thrust, mimicking the kinematic principles observed in cetaceans. According to company disclosures, WaveDrive delivers up to 20% fuel savings per vessel, a 3-5 year return on investment, and avoids approximately 75,000 tonnes of CO2-equivalent per vessel annually. Beyond propulsion, the unit provides pitch damping for seakeeping and automatically lifts in harsh conditions. The technology was co-developed with Ifremer (France's national marine research institute) and validated through computational fluid dynamics using Cadence's Fidelity Fine Marine solver. The system is designed to be retrofit-compatible with the global fleet of 100,000+ ocean-going vessels.

The company targets enterprise maritime customers — container ship operators, LNG carriers, oil and chemical tanker operators, bulk carriers, and roll-on/roll-off fleets — and pursues them through direct enterprise sales with custom pricing and multi-year contracts. Hardware sales are the primary revenue model, with technology licensing identified as a longer-term secondary stream. The company is headquartered in Brest, France, with its registered office in Plouzane (legal entity BLUEFINS, SIRET 892 357 575).

Bluefins remains pre-commercial: as of the latest dataset, the company had not yet recorded customer revenue, and first sea trials — the prerequisite for commercial deployment — were scheduled for early 2025. Capital efficiency is supported by a €4M seed round closed in September 2024 with GTT Strategic Ventures, BNP Paribas Développement, and Breizh Up. The core team of eight is anchored in Brest's marine engineering cluster, including a PhD hydrodynamic engineer, and is led by CEO Philippe Ruffin alongside Founder & CTO Olivier Giusti.

Core offering

Bluefins designs, develops and sells the WaveDrive system — a whale-tail-inspired articulated hydrofoil mounted at the stern of ocean-going vessels that harvests wave and swell-induced vessel motion to deliver controlled propulsive thrust, displacing fuel consumption. The hardware is sold for retrofit on existing vessels or integration on newbuilds across container ships, LNG carriers, tankers, bulk carriers, general cargo and roro vessels.

Product overview

Bluefins is a single-product company offering WaveDrive, a whale-inspired auxiliary propulsion system for ocean-going vessels. WaveDrive consists of a hydrofoil attached to the stern of a ship through a set of mechanical articulations; it harvests ocean motion (wave and swell-induced vessel movement) and converts it into controlled propulsive thrust, directly displacing fuel consumption. The system is designed for retrofit on existing vessels as well as integration on newbuilds, and is compatible with all ocean-going vessel types including container ships, LNG carriers, oil and chemical tankers, bulk carriers, general cargo ships, and roro vessels. WaveDrive provides 20% fuel savings with a 3 to 5-year return on investment, while reducing CO2, SOx, and NOx emissions and providing pitch damping for improved vessel stability.

Products and services

• WaveDrive Auxiliary Propulsion System The WaveDrive is an auxiliary propulsion system for ocean-going vessels consisting of an articulated hydrofoil attached to the stern of the ship through mechanical arms. It harvests wave and swell-induced vessel motion and actively converts it into controlled propulsive force, delivering net thrust alongside the main engines and directly displacing fuel consumption. It is designed first for retrofit on existing vessels but is also suitable for newbuilds, works across all ocean-going vessel types (container ships, LNG carriers, oil and chemical tankers, bulk carriers, general cargo and roro vessels), automatically lifts in harsh sea conditions for safety, provides pitch damping, and targets 20% fuel savings with a 3-5 year ROI.

Direct peers

• Norsepower: Norsepower develops rotor sails (Flettner rotors) that provide auxiliary wind propulsion to ocean-going vessels, reducing fuel consumption and emissions. It is the most established direct competitor to Bluefins in the wind-assisted propulsion space, with multiple commercial deployments across tankers, bulk carriers, and roro vessels.
• bound4blue: bound4blue manufactures WindWings, rigid sails installed on cargo ships that harness wind power for auxiliary propulsion. It directly competes with Bluefins in delivering retrofittable emissions-reduction technology to commercial shipping, targeting similar customer segments and value proposition.
• Anemoi Marine Technologies: Anemoi produces rotor sail technology for auxiliary propulsion on commercial vessels, including bulk carriers and tankers. Like Bluefins, it sells emissions-reducing retrofits to shipping operators with the same fuel-savings business case, and competes for the same retrofit installation slots.
• Econo-Wind: Econo-Wind develops automated towed sail systems that provide auxiliary wind propulsion to cargo ships, reducing fuel use and emissions. It serves the same ocean-going commercial vessel market as Bluefins with a similar retrofit-first, fuel-savings-driven value proposition.
• Becker Marine Systems: Becker Marine Systems offers CODA Wings, a wind-assisted propulsion solution for commercial ships. As an established marine equipment supplier already working with major shipyards, it represents a direct competitor to Bluefins for retrofit and newbuild auxiliary propulsion contracts.

Emerging players

• Smart Green Shipping: Smart Green Shipping develops rigid sail technology (FastRig) for retrofit on bulk carriers, targeting fuel and emissions reductions. It is an emerging player in the same wind-assisted propulsion category as Bluefins, with overlapping customer base in the bulk carrier segment.
• Windship Technology: Windship Technology develops wing-sail hybrid propulsion systems combining rigid sails with engine optimization. It targets the same maritime decarbonization use case as Bluefins, with partial overlap in addressing ocean-going vessel operators seeking fuel and emissions reductions.

Broad incumbents

• Wärtsilä: Wärtsilä is a major marine engine and propulsion systems manufacturer offering a broad portfolio of alternative fuel and hybrid solutions for shipping. While it does not compete in wind-assist hydrofoil propulsion, it is the dominant incumbent in marine propulsion broadly and the most likely strategic acquirer or OEM partner for Bluefins.
• ABB Marine & Ports: ABB provides electric propulsion, hybrid systems, and digital solutions for the marine industry, including emissions-reduction offerings for shipping operators. As a broad incumbent in marine propulsion and power, it is adjacent to Bluefins' auxiliary propulsion technology and a potential integration partner for vessel electrification roadmaps.

Others

• Cadence Design Systems: Cadence Design Systems provides Fidelity Fine Marine CFD software used by Bluefins and Ifremer to model and optimize WaveDrive performance under real-world wave conditions. It is an enabling technology partner rather than a competitor, but is closely tied to Bluefins' technology validation pathway.
