Deflector.

摘要

A deflector which is intended for installation in the tow-line (4, 5) between a towing vessel and a tow which is located in the water, e.g. a cable with seismic sources or seismic source array, is suspended from a float (1) and is installed between a tow-point (7) on the tow-line (4) and an attachment point (8) for the further connection (5) to the tow. In order to be able to locate the deflector in a desired position in relation to the towing vessel and compensate for alterations in the effects of forces from the tow or vessel in addition to movements in the water, the tow-line (5) which leads to the tow from the deflector body (2) is attached to the deflector via a pivotable lever (10) which is situated at the same height as the deflector body's lifting force centre. The tow-point (7) for the tow-line (4) is provided at one lateral surface of the body in front of its vertical centre line. An additional deflector wing (18) may be incorporated in the tow-line (5). <IMAGE>
