摘要:
A method for handling a faired cable (1) using a fairing (2), said cable being towed by a vessel (100) on-board which is installed a winch (5) for winding up and unwinding the faired cable (1) through a guide device (4) for guiding the faired cable, the method comprising: - a first step (10) of monitoring the cable (1), in order to detect whether the fairing (2) has undergone a double twist around the cable comprising a complete submerged twist and a complete airborne twist, - and, when a double twist is detected, a first step (11) of hoisting the faired cable (1) during which the faired cable (1) is hoisted, the first hoisting step (11) being implemented in such a way that the complete submerged twist at least partially exits the water and does not enter the guide device (4).
摘要:
A towing assembly comprising a towing and handling device intended for towing an elongate faired element, comprising a winch (5) for winding and unwinding the elongate faired element (1) through a guide device (4) for guiding the elongate element (1), the guide device comprising a first groove (24) of which the bottom (26) is formed by the bottom of the groove of a pulley (4), the first groove (24) being delimited by a first surface (25) having a concave profile in a radial plane of the pulley, the width of the first groove and the curvature of the profile of the first curved surface in the radial plane being determined in such a way as to allow the fairing element to be turned over, by rotating the fairing element about the axis of the elongate element under the effect of the traction of the elongate element relative to the guide device along the longitudinal axis of same, from an inverted position in which the trailing edge of the fairing element is turned towards the bottom of the first groove, to an acceptable position in which the leading edge of same is turned towards the bottom of the first groove.
摘要:
The invention concerns bodies towed behind a vessel. Said objects are commonly referred to as fish. According to the invention, the fish (12) comprises a housing configured to move in the water in a main horizontal direction (25), at least one appendage (27; 29) configured to generate downward hydrodynamic lift (30) when the fish (12) is moving in the water as a result of towing, and a lock for reducing the hydrodynamic lift of the appendage (27; 29).
