Foil-assisted catamarans. Up to 50% less drag. Over 80% less energy in electric configuration.
Enviroinventions designs and licenses the EnviroCat platform — foil-assisted catamarans from 15 to 50 metres, available in electric, hybrid, and ICE-powered configurations. We work with passenger ferry operators, transport authorities, offshore crew transfer operators, port and emergency services, and yard partners across Norway and the Gulf.
Up to, at design speed. Diesel-to-diesel newbuild replacement.

EC16.5, EC18, EC22, EC34, and Custom variants.
Three paths from where you are
Why foil-assist
EnviroCat sits between conventional catamarans (no lift, limited drag reduction) and full hydrofoils (maximum drag reduction but active control, no retrofit, no conventional propulsion). The foil-assist hull delivers passive lift, no active control surfaces, conventional-propulsion compatibility, and retrofit feasibility.
The design draws on four decades of high-speed catamaran naval architecture by CTO Ola Lilloe-Olsen — 130+ vessels realised since the early 1980s, including electric and hybrid ferries — and on the Norwegian marine-electrification supply chain we work with every day.
See the technologyHow we work
We design and license vessel platforms; we do not own yards or operate vessels. ESS Marine Ltd handles Gulf commercial activity. Yards integrate complete EnviroCat engineering packages — analogous to how Volvo Penta delivers propulsion systems — and operators receive vessels configured to their specific route through a consultative analytical engagement.
The engagement covers route and operational profile modelling, energy budget calculation, configuration optimisation, total-cost-of-ownership analysis, and fleet renewal scenario modelling. It is integral to the platform offering, not a separate consulting service. It is the most differentiating part of working with us.
See the approachPartners
The EnviroCat platform integrates technology from Volvo Penta, Kumera Helseth, Servogear, Brunvoll, Brunvoll Mar-El, ZEM, Stadt Towing Tank, Maritime Engineering, and DNV. The platform is propulsion-agnostic across CPP, pod, and waterjet options, with electric drives from multiple compatible suppliers.
