ABSTRACT:
An apparatus is disclosed for balancing a seismic streamer cable. The housing is comprised of a first and a second valve coupled about the streamer cable. Each valve has a clasp adapted to engage a socket on the other valve to ridigly fasten the valves together about the streamer cable. The housing surrounds and retains weights applied to the streamer cable. An alternate embodiment is disclosed where the weight is integral with each valve. The exterior of the housing is designed to produce laminar flow conditions for the fluid passing over the housing as the cable is under tow, reducing ambient noise detected by the sensors within the streamer cable.
