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.
ECO Trawl AS was launched in June 2016 and is based on an idea of automating trawling using offshore and marine technology.

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 is improved because more precise driving of trawl in depth and course provides faster trawling and less by-catch
HSE
Better HSE (health, safety and environment) as it is not direct force path from trawler to trawl. The cables from thruster to the trawl net has low forces and if the trawler gets stuck it's time to react
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 (thrusters) 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 Thruster 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.
Til Preliminary concept studies show that an average trawler will increase the catch volume by up to 20%, saving 25-30% 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 thruster 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 Thruster unit. the analysis have been performed by CFD Marine
