Abstract: An angular member provided on seismic cables towed by a vessel and laterally displaced in parallel and in relation to the course of the vessel comprises a frame at least partly enclosing the cable in the area of angular deflection between an inner cable portion extending obliquely to the towing direction and the active main cable portion. The frame is formed of two frame plates secured in spaced relationship and having at the lead-in end for the cable a cable-fastening device and at the other end a pivotable ramp swingable in the plane of the frame plates. The ramp has a further fastening device for the cable. Another fastening device is pivotably connected to the frame plates for connecting thereto a wire to a paravane or the like. When towed in the water the angular member absorbs most of the forces normally exerted on the cable at the area of angular deflection.

Abstract: A reinforcing device to achieve stable fastening points for the inner portion (2) of seismic cables, especially cables that are towed laterally displaced in parallel in relation to the towing vessel and provided with at least two layers of armoring (5,6) intended for absorbing stretch loads on said cable, comprises a fastening means on at least one of the end areas of the inner portion (2), and gripping surfaces for external equipment and shaped with at least two securing chambers (3,4). For assembling the outermost layers of armoring (5,6) of said cable are separated and inserted into one chamber each (3, 4), wherein they are secured to form an integrated connection with said casing (2).
