Method, device and installation for determining the direction of the strand entering the water of a mooring or towing cable on a craft

摘要

The mooring or towing cable (6) passes over a return grooved pulley (5) which is supported by a beam (3) via a mounting system (4) having three orthogonal elementary axes of articulation which allow a rotation (u) in separation, a rotation (v) in deviation and a rotation (w) in pivoting. Knowing the direction of the strand (61) on the craft side and after measuring at least two of the elementary angles of rotation (u, v, w), a computer operating in real-time calculates the orientation of the strand (62) entering the water. Monitoring of the direction adopted by the cable strand entering the water during the operation of mooring or towing various machines such as dragnets, trawls or sonars, for example. IMAGE
