Mathematical substantiation of parameters of safe pelagic trawling in the canyon

Abstract

The authors have offered and proved the following security options of pelagic trawling in the sea canyon: the tolerance of the vessel from the optimal track; the minimum width of the canyon giving opportunity for the conditions to ensure the safety of the trawl; margin width of the canyon on the trajectory of the trawl maneuvering due to changes in the direction of the canyon axis; deviation from the axis of the trawl canyon maneuvering owing to changing the axis direction at any time after rotation; time when the deviation of the trawl from the canyon axis while maneuvering owing to changing the axis direction reaches some predetermined value
