Embodiment Construction

[0090] As previously shown, the principle of the present invention is to propose a seismic data acquisition system, wherein the data transmission device integrated in the seismic streamers (streamers) is used for the transmission of data sent from the streamer position detection device and from the ocean feeding Common to the transmission of those data from animal detection and / or locating devices, the latter being integrated in modules coupled to seismic streamers.

[0091] figure 1 A schematic representation of a first embodiment implementing the invention.

[0092] According to this embodiment, the module 2 is clamped to the seismic streamer 1 by means of clamps 3 . Thus, each module 2 extends along the side of the seismic streamer, substantially parallel to the corresponding part of the streamer.

[0093] The clamping means are of the type currently used for clamping acoustic positioning modules or speed measurement modules or compass modules or immersion measurement mod...

Abstract

Disclosed herein is a system of acquiring seismic date in a marine environment, which includes: seismic streamers towed by a vessel; and means for detecting and / or locating marine mammals, characterized in that said marine mammal detection and / or location means are secured to said seismic streamers.

Description

technical field [0001] The field of the invention is the acquisition of seismic data. More specifically, the invention relates to equipment for analyzing the seabed. [0002] The present invention relates in particular to the petroleum exploration industry using seismic methods, and can be applied in any field with a system for acquiring seismic data in a marine environment. Background technique [0003] In the field of the present invention, the work of collecting geographic data in situ usually utilizes a network of sensors (indicated by the term "hydrophone" with respect to the collection of data in the marine environment). [0004] The previously mentioned hydrophones are distributed along the cable, forming a linear acoustic antenna commonly referred to as a "streamer" or "seismic streamer". A network of seismic streamers towed by seismic vessels. [0005] Seismic streamers are assembled from individual components equipped with seismic sensors and associated analog-t...
