  • Cable, in particular seismic streamer, including a plurality of chambers forming a necklace float, and tools for filling, degassing or connecting the chambers of the cable
    Patent number: 6644232
    Abstract: A marine cable includes chambers forming a necklace float. For filling, degassing the chambers and for connecting two successive chambers, the cable includes an intervention orifice between the chambers and with which the chambers communicate. Connection of the chambers to the intervention orifice is controlled by two valve mechanisms which each include an obturator spring-loaded against a communication opening and a guide rod which, when the obturator closes the opening, lies partly in the intervention orifice so that it is possible to push back the rods of the valve mechanisms from the intervention orifice for selective connection of the intervention orifice to one or the other of the two chambers or with both at the same time.
