About us
The background for the project is that today's trawling has some challenges: High fuel consumption, damage to the seabed, trawl net damage, challenges with controlling the trawl's course and depth, and trawler’s traction power determines the trawl size and by-catch. At the same time, the trawler industry is using more technology and is more open to automation.

Using ECO Trawl have the following advantages:
Bigger
Bigger trawl than before and can fish faster and more efficiently
Risk
Less risk of trawl damage
Fuel
Less fuel consumption
Quality
Product quality (fish) is improved because of the more precise trawling process and the trawls being emptied more often gives better quality for the entire catch.
HSE
Better HSE (health, safety and environment) for the crew as there is no direct force from the trawler to the trawl and this makes it much safer to be on deck and operate the equipment. In addition, its less likely to get stuck below water.
Enviroment
Environmental impacts such as reduced fuel consumption, reduced ground contact at bottom trawling, reduced by-catch, reduced greenhouse gas emissions and reduced seabed damage
Technology
The idea is to place powerful electric propeller units (AUDs) where the trawl doors are today on a trawl. The propeller units replace the traction power from the tractor propeller and the propeller units get electric power from a generator on the trawler. The AUD units are controlled in the water with side and depth rudders. A trawler control system collects sensor data and controls the propeller units and thus the trawl's course and depth in the water. Such a solution will provide a far more environmentally friendly and efficient trawl.
Preliminary concept studies show that an average trawler will increase the catch volume by up to 20%, saving 30% fuel in addition to reducing ocean floor damage and reducing by-catch. The ROI for trawl owners is estimated to 6-12 months. The Eco Trawl will have great value nationally and internationally.

The AUD replaces the trawler pull and has control surfaces for depth and heading control
Extensive CFD calculations of the ECO Trawl concept have been performed, verifying the forces and controllability of the AUD unit. The analysis have been performed by CFD Marine
