Problems solved by technology

So, this solution is not very effective at guiding the streamers and pressure sensitive buoys to the surface due to the smaller bags
In addition, the gas charge generator with carbon dioxide or with powder and cooling system is bulky and not suitable for integration in the airfoil
If the retriever is accommodated in the body, the proposed system has similar disadvantages to the retriever system of US 6 621 886

Embodiment Construction

[0075] related to existing technology figure 1 Up to FIG. 3 has been described above and will not be discussed again.

[0076] we are now about Figure 4 with 5 A retriever system 40 according to an embodiment of the present invention is presented.

[0077]The retriever system 40 comprises a body 41 which in this embodiment constitutes a navigation control device or a pressure sensitive buoy. In this embodiment, the body 41 contains inline modules 42 that run along the streamer 20a ( Figure 4 shown in ) placed in series and contain a magnetic sensor (such as a magnetometer, compass or Hall sensor, not shown) and electronics (not shown). The module provides depth control and lateral control (steering). The main body 41 also contains a frame element 11 , which in this example is a tubular frame element, is free to rotate around the module 42 . A swivel (not shown) may be used to facilitate rotation of the body 41 about the insert module 42 under tension.

Abstract

It is proposed a retriever system (40) for a streamer including: - a body (41), placed in series along the streamer or in parallel with the streamer, - an inflating generator (51) and - an inflatable element (52) being configured to be folded in a rest state and to be inflated by the inflating generator (51) and spread in an active state, the inflatable element (52) having a shape of a wing in the active state and including two different portions, a first portion including a leading edge (65) and a second portion including a trailing edge (66), the passage from the rest state to the active state being activated in predetermined conditions.

Description

technical field [0001] The field of the invention is the acquisition of geophysical data. The present invention relates to the equipment required for studying the seabed and the properties of its sedimentary layers. [0002] More precisely, the present invention relates to a retriever system for a streamer, such a retriever system being adapted in the event of a failure, e.g. a failure of the streamer or of a container, or for A condition in which the control device (also commonly referred to as a "pressure sensitive bird") is too deep, or a condition in which the pressure sensitive bird is out of control. Pressure sensitive buoys are suitable for controlling the depth and / or lateral position of a towed acoustic linear antenna (commonly referred to as a "streamer"). [0003] The invention is particularly applicable in the oil exploration industry using seismic surveying methods (offshore oil surveying), but may be of interest to any other field requiring a system for perform...
