Embodiment Construction

[0045] [45] figure 1 The holding and guiding device of the invention is shown for correct holding and positioning of a towed submersible object 3 , in particular a towed linear acoustic-based antenna, here schematically represented in the form of a long cable.

[0046] [46] The device 1 comprises a hollow central body 5 and a plurality of individually orientable stabilizing wings 7a, 7b, 7c (here 3).

[0047] [47] The body 5 has a longitudinal axis 5a.

[0048] [48] ​​This body consists of a fixed central part 9 and a concentric shell 11 mounted rotatably about the central part with an axis 5a together with wings about which the wings can be rotated sideways in the event of an obstacle. open.

[0049] [49] Furthermore, the wings extending along a transverse (radial) axis to axis 5a are mounted rotatably about their respective transverse axes 13a, 13b, 13c (approximately 5 to 30°, preferably 20°).

[0050] [50] For this movement, each wing is preferably fixed towards its roo...

Abstract

The invention relates to a navigation control device for a towed submersible object (3), in particular a towed linear acoustic-based antenna. The device comprises a main body (5) with a longitudinal axis (5a), equipped with fixing means (53, 55) for detachably fixing towed objects and a plurality of stabilizing wings (7a, 7b, 7c), each Attached to the main body, extending along an axis (13a, 13b, 13c) transverse to the longitudinal axis of this main body, each wing can be oriented relative to the main body by rotation about its transverse axis by control means to vary the wing The inclination of the board.

Description

technical field [0001] [01] The invention relates to a navigation control device for a towed submersible (sous-marin) object, in particular a towed linear acoustic antenna. [0002] [02] In particular to ensure the acquisition of seismic data, in particular three-dimensional data, it is known to tow a submersible object such as the aforementioned antenna at sea. Background technique [0003] [03] Typically, such antennas can be described as long cables. Typically, multiple cables are arranged side by side, often ten, and are towed together. [0004] [04] However, it is important to position these devices correctly relative to each other (especially avoiding that they cross each other). Also, it is useful to determine and control its depth of descent. [0005] [05] Someone has proposed such a navigation control device for a towed submersible object. [0006] [06] However, problems remain, related in whole or in part to the reliability, efficiency of these devices, their c...
