Abstract
A means for terminating of splicing a cable intended for towing air-water guns behind a seismic vessel. The end of the cable, or of each cable section, is guided into the housing of the termination member. The termination is formed with separately located connection sites for the cable components. The cable's tension-relieving wires (3) are guided into a first chamber (I) in the housing and fastened to the supporting structure of the chamber (I), i.e., the housing. The chamber (I) is filled with a water-repellant lubricant. The cable's conductors (9) are guided individually through the first chamber (I) and through a sealed passage (10) in a wall (14) defining a second, watertight chamber (II) which is filled with an electrically insulating, hydrophobic, water-emulsifying liquid. The chamber (II) is also provided with a pressure compensator (8). The conductors (9) are guided further to underwater connectors (15) disposed in the diametrically opposed end wall (13) of the housing, optionally with an intermediate connection of electronics circuitry (16). The compressed air hose (17) of the cable is conducted through the first chamber (I) and through a central separate channel (18) in the second chamber (II) to a coupling (19) outside the housing.
