The MARELEC Protec Fishing System is mainly used for beam trawling. Constant tension and wire length measurement is monitored and displayed in the wheelhouse. When the tension builds up at one side, alarms are sounded so the captain can act. Automatic safety measurement can be implemented to protect both crew and vessel. Safety is the number-one priority, just like on land.
Beam trawlers have 2 sets of nets which they shoot from the beams at the side of the vessel. Those beams have quite a bit leverage on the vessel when the tension is not equal. When fishing on a rocky bottom, for instance, there is a higher risk that a net will get stuck behind a rock. The winch brake will automatically release in ABS mode and so reduce the tension.
There is always a risk of getting stuck, even when fishing on clean ground. Small starfish, sand or mud could fill up the nets and cause an overload. This overload is displayed, and alarms are sounded to enable preventive action to be taken.
