ABSTRACT:
A non-fluid-filled streamer cable or towed array for performing seismic surveys in water-covered areas includes a plurality of serially coupled active cable sections. Each active cable section includes an electromechanical cable that contains a single central strain member. A wire bundle is placed around the central strain member for transporting electrical power and data through the active section and an inner protective jacket is formed around the central strain member and wire bundle. A foam material is extruded around the inner protective jacket to provide a predetermined buoyancy to the fully assembled active cable section and an outer protective jacket is formed around the foam jacket. A potting compound is formed between, and bonds to, the inner protective jacket and outer protective jacket to provide a water block at each hydrophone location.
