Title
(EN) CONTROL DEVICE FOR POSITIONING AN INSTRUMENTED CABLE TOWED IN WATER
(FR) DISPOSITIF DE COMMANDE DE LA POSITION D'UN CÂBLE INSTRUMENTÉ REMORQUÉ DANS L'EAU
Abstract
(EN)
Control device (10, 50) for controlling the position of an instrumented cable towed in water, such as a marine seismic streamer, and/or an instrumented towed cable array (streamer array) with the possibility of controlling the individual instrumented cables both with in shape and position in relation to other instrumented cables and by that counteract cross currents and/or other dynamic forces which affect a towed array behind a seismic survey vessel, which control device (10, 50) is provided with one or more acoustic means, such as acoustic transmitter/receiver elements (40), arranged to or integrated in the wings (11, 52), main body (12, 53) or motor and drive gear housings (51) of the control device for determination of position and distance.
(FR)
L'invention porte sur un dispositif de commande (10, 50) de la position d'un câble instrumenté remorqué dans l'eau, tel qu'une traîne sismique marine et/ou un réseau de câbles instrumentés, offrant la possibilité de commander individuellement des câbles instrumentés pour ce qui est de leur forme et de leur position par rapport aux autres câbles instrumentés, et de contrecarrer les courants transversaux et/ou les forces dynamiques affectant les réseau de câbles remorqués par des navires de relevés sismiques. Le dispositif de commande (10, 50) est pourvu d'un ou plusieurs moyens acoustiques tels que des émetteurs/récepteurs (40), placés sur ou intégrés, aux ailerons (11, 52), au corps principal (12, 53) ou aux carter (51) du moteur et de la boîte du dispositif de commande, pour déterminer la position et la distance.
