ATW Trawl Winch Control


The ATW Trawl winch control is based on automatic load control for trawl winches. The ATW software is designed and assembled by Naust Marine technicians. The system shoots the net to pre-set length that is decided by the operator each time, with equal tension on both wires at all times. During trawling, the ATW Trawl winch control system keeps the trawl in optimal geometrical position. The result is maximum catch with minimum operational cost.

The components of the ATW Trawl winch control system are of highest quality and specially selected in light of over 30 years of experience of Automatic Trawling in the North-Atlantic.

 

The system is available for three main types of trawlers:

  • Danish seine netter
    The Towing winches control  have an option of operating as Danish seine winches with high speed for shooting.  The tension in the wires and the wire length are measured by Rpm and Current in the motors. The motors are specially selected for high speed during shooting and high torque on low rpm

  • 2x Split Winches
    Both winches can work simultaneously and with the same torque. The tension in the wires and the wire length are measured by the ATW Trawl winch control directly from the motor current and the rpm of the motors. These measurements are used to adjust the torque to keep constant tension in both wires. This function is very useful in rough sea and when necessary to change course frequently.

  • Twin-Rig Trawling
    Stb. and Ps. winches can work simultaneously and with the same torque. The tension in the wires and the wire length are measured by the ATW Trawl winch control directly from the motor current and the rpm of the motors. These measurements are used to adjust the torque to keep constant tension in the Stb. and Ps. wires. The length of the mid wire is adjusted in accordance with the length of the Stb. and Ptb. wires.

 

Why choose ATW?

Quality Components for Heavy-Duty Work!  The components of the ATW Trawl winch system are of highest quality and specially selected in light of almost 30 years experiences of Automatic Trawling in the North-Atlantic.

  • Maximum Fishing Efficiency 
    Our experience in designing and maintaining Auto-Trawl systems, has tought us to integrate factors like power, speed and volume to obtain maximum efficiency of each trawler. With the help of the newest technology, like the Auto-Gen Power Management system, the power of the main engine and auxiliary engines is integrated to increase the power and propulsion of the ATW Trawl winch winch system.

  • Double Security
    The ATW Trawl winch system is based on PLC technology of the highest industrial standard. If the PC-Control Computer in the front bridge brakes down, you can still control the ATW system from the aft bridge. In such instances all automatic functions of the system are in order.
