Controllable trawl doors TYPE 42 BLUESTREAM

Invest in our controllable trawl doors for unmatched versatility, allowing you to tailor them to your vessels requirements and fishing patterns. Experience eco-friendly, cost-effective fishing with reduced co2 emissions and quick setup adjustments, ensuring better profitability while minimizing environmental impact.

We are very proud of our TYPE 32 & 42 BLUESTREAM designs – the only trawl door on the market that has both our patented moveable foils, which can minimize the total area of the doors and thereby adjust spreading power and water resistance. In addition, the design is unique because it can be customized for the vessel’s needs or specific fishing patterns. This design fits perfectly on the stern or on the side of the vessel.

The doors are typically manufactured in HARDOX450 or STRENX performance steel with a size and weight specified to suit the trawl and speed used for each fishery.

Once the balance of weight has been calculated and suited to our satisfaction, the doors are constructed and include the following: HPU (High Pressure Unit), Software, Adjustable hydraulic foils, height sensor, hydrophones, WIFI antenna, and Subsea Lithium batteries.

Our software is an open-ended design that can be customized and adapted to a captain’s specific needs or preferences.

The system in the trawl doors is being controlled via wireless acoustic communication from hydrophones that are installed in the hull of the vessel. The hydrophones get their commands from the captain on the bridge, who controls the software.

Key adjustment possibilities include:

• Changing or keeping a certain fishing depth.
• Keeping the doors off the bottom (less environmental impact and less CO2 emissions).
• Controlling the depth of doors individually or simultaneously.
• Shooting and hauling faster (less CO2 emissions).
• Counteracting strong tides.
• Decreasing or increasing resistance and spread from trawl doors (less CO2 emissions).
• Controlling pitch and roll.
• Changing the fishing setup in no time, without crew on deck.

All above-mentioned headpoints are achievable with our controllable trawl doors and will result in a more economical and environmentally friendly fishing setup that will lead to less CO2 emissions pr. kilogram of caught fish, while also resulting in a better profit.
