A method to determine patterns for changing parameters of the rope-net shell of midwater trawl along its length

Abstract

A technique for designing the rope-net shell of midwater trawl is described on example of the trawl Sirius Shelf project AS 11.012.000 designed by Aquaservice Ltd. Diagrams of the rope-net shell parameters distribution along trawl are used. The technique allows to analyze variations of these parameters for their optimization. A wide range of the trawl designing criteria can be taken into account using the diagram approach.
