Method for performing a search su00ecsmica maru00ectima with a series of tapes su00ecsmicas, series of tapes and tape su00ecsmica su00ecsmicas device connector cable entry ".The invention relates to methods and apparatus for marine seismic survey, 3D.In which a series of laterally spaced strips (14) containing hydrophones is towed behind a survey vessel (10).In order to reduce the drag produced by the series, instead of towing each tape (14) by its own input cable protected (18, 20).At least two strips on each side of the ship is towed from a single respective input cable protected.Each of these unique cable entry (18, 20) has a device connector (22, 24, 26) with a series of links of trailer connected therein, the device connector (22, 24)26) having a body (44) which transmits forces between the towing protected external coating of portions of the input cable connected to each side of the device connector (46).And a connection coupling (72) attached to the body (44).
