“ENVIROCAT” EC_34
The all new Foil Assisted Catamaran for Electric Propulsion
The new catamaran was initially developed under a 2 year development contract with the County of Trøndelag.
Recently a new design contract was awarded as a competition by “Fremtidens Hurtigbåt”, a co-operation between four Counties in Norway.
On December 4. 2022, the report was delivered after phase 2 in the project, and our group has indeed worked hard to create a modern and safe high-speed vessel with zero emission, high comfort and not least; exceptional energy efficiency.
Any new technology that enables zero-emission is adding significant weight to a vessel. Batteries are heavy, and despite the fact that most people think hydrogen is a light solution with high energy, the total added weight is just as high as on our preferred solution using batteries and battery-exchange due to all safety add-ons with hydrogen.
The base for our development-work has been “Less is More”!
The foil assisted catamaran has been developed for minimum use of complex control-systems. Using fixed foils without moving rudders reduces the complexity significantly compared to a full foil-borne vessel where active control is mandatory using fully submerged foils.
The other new aspect of the concept is the battery-change system where the catamaran is docked in a specially designed floating terminal. An autonomous system positions the catamaran and locks it to the terminal. The used batteries onboard are transferred to the charging station, and fresh batteries from the terminal onboard. Battery-life is expended due to the low C-rate charging.
