Vision Of The Fjords

Brødrene Aa is pleased to announce that our new sightseeing vessel, Vision of The Fjords, has been delivered to the norwegian operator The Fjords, on Saturday the 16th of July. The new hybrid-electric carbon fiber catamaran is designed and built by Brødrene Aa. The ship is designed to carry 400 passengers and will be operating in Nærøyfjord on the west coast of Norway.

The Seasight design

Seasight is the brand name of this new Brødrene Aa design. It is a premium sightseeing vessel designed from the ground up to enhance the passengers’ sightseeing experience and reduce the vessels environmental footprint.

The exterior is inspired by a twisting mountain road and gives the passengers freedom to walk around the ship while enjoying the scenery. Inside, the vessel has passenger accommodations on two decks, featuring large panoramic windows, seating in a variety of configurations and a large refreshment kiosk on the main deck.

P42 Hydrolift

Hydrolift P42 SAR is a new rescue vessel designed for high speed operations based on a modular design with focus on a high level of safety, functionality and cost of ownership. The design was developed by Hydrolift (a renowned Norwegian boat manufacturer) and the sister company Eker Design, working closely with the Norwegian Society for Sea Rescue. In addition of being an innovative, efficient and a fast running vessel this new class also has great towing capacity and the possibility of carrying a watercraft. State of the art navigation equipment VHF, double chart plotters, radar and thermal imaging camera is also included.

FiReCo has been a close collaborator and/or subcontractor in the developing process.

DACOMAT – Damage Controlled Composite Materials

The objective of DACOMAT is to develop more damage tolerant and damage predictable low cost composite materials in particular aimed for used in large load carrying constructions like bridges, buildings, wind-turbine blades and offshore structures. The developed materials and condition monitoring solutions will provide high tolerance for manufacturing imperfections and high capacity to sustain damages. This will enable large composite structures to be manufactured and maintained at low cost.
