Creative and Dynamic Ship Design by Naval Architect Ola Lilloe-Olsen

Designs that since 1985 has earned a reputation for superior seakeeping with proven performance in Norway and World-Wide.

"Proven Ocean Space Design"

Mr. Lilloe-Olsen, a graduate from the University of Glasgow in 1977, has spent his career working in Research, Development and Design of maritime constructions with special emphasis on High Speed Commercial Vessels.

Lilloe-Olsen moved to the little village of Hyen in Nordfjord in 1979, and established the first private commercial hydrodynamic test centre in Norway; Teknisk Modell-Senter A.s. The towing tank was 47 metres long, 3 m wide and 2 m deep, and a variety of model tests were carried out during the period from 1979 to 1991. In 1985 Lilloe-Olsen designed 5 of 8 new vessels totally delivered by Brødrene Aa that year, and it represented the start of a long carrier with more than 130 vessels built to date for owners from many countries around the world. The latest Development work has been on emission-free High Speed Catamarans. The result is a unique hull-design capable of carrying requires payloads at high speed with zero emission. The latest developments were presented to the public at the HRF High Speed Ferry conference in Bergen in the fall of 2025. The work now is continued in the project “Fremtidens Hurtigbåt - verifisering av design”. TTo develop the EnviroCAT project further and to commercialize the concept for build and delivery, Enviroinventions AS was founded in 2023.

In 2024 the qwner structure changed, as Bjørn Utgård joined as a main share-holder along with While1 (Jørn Sandvik Nilsson) and Ola Lilloe-Olsen.

Development work continued with full focus on optimalization of every detail of the concept. Per February 2026, a compete new foil-system is developed and ready for final engineering and production. An extensive co-operation with ESS Marine who now is the sales partner and has secured a contract for the first two EC 16.5 Crew transfer vessels for ANOC in UAE.

Enviroinventions hav at the moment 4 different sizes in the works;

EC 16.5 for 48 passengers, fully electric and 25 – 35 kn. service speed and long range

EC 18  PILOT and FIRE – fully electric or hybrid for emergency response and safe operation

EC 22 – High Speed Passenger ferry for 78 – 97 passengers, 35 knots and long range

EC 34 - High Speed Passenger ferry for 230 passengers, 35 knots and long range

EC 34 – Super HS – 230 passengers and 45 knots service speed!

All vessels fitted with Volvo Penta IPS propulsion and ZEM LFP batteries.

Maritime Engineering (MENG) and the very skilled team there is our engineering department, and responsible for detail engineering.

For development of the completely new foil system, Christer Widmark of Widewo AB and Audun Yrke @ MENG. Super creativity and experience on foils!
