Abstract: A solid marine seismic cable assembly (10) includes a cable (16) hydrophone housings (20), a buoyant filler (24), and an outer protective jacket (28). The cable includes a load-bearing fiber bundle (32), data-transmitting wires (36), power conductors (38), optical fibers (40), and a protective sheath (42). The data-transmitting wires (36), power conductors (38), and optical fibers (40) surround the load-bearing fiber bundle (32). The protective sheath (42) surrounds the assembly of the data-transmitting wires (36), power conductors (38), optical fibers (40), and the load-bearing fiber bundle (32). The hydrophone housings (20) affix around the cable (10) in a spaced-apart relationship. Each hydrophone housing (20) includes a hydrophone module (56), and each hydrophone module contains a hydrophone (14). The buoyant filler (24) surrounds the cable (16), and separates the hydrophone housing (20). The outer protective jacket (28) surrounds the hydrophone housing (20) and the buoyant filler (24), enclosing the cable (16) assembly.

Abstract: A low-profile hydrophone module for a marine seismic system (10) includes a block (108) having a curved surface (118) and a receiving surface (130) in which an open cavity (134) is disposed, a hydrophone assembly, to which lead wires (154) attach, disposed in the cavity, lead wires which pass out of the cavity, and a sound-transmitting material which fills the cavity. In another feature, the hydrophone assembly includes a hydrophone and a baffle material (162), the baffle material enclosing the hydrophone, the cavity is sealed aroud the lead wires, the sound-transmitting material is oil (170), and a cover sealingly affixes over the cavity. In another feature, the hydrophone assembly includes a hydrophone and a frame, the cavity is sealed around the lead wires, the sound-transmitting material is a potting sealant (135), and a cover sealingly affixes over the cavity.

Abstract: A hydrophone housing (20) includes a hydrophone module or cap (56), which contains a hydrophone. The hydrophone housing (20) clamps around a marine seismic cable (16). The hydrophone housing (20) further includes a first portion (78) and a second portion (82). One of the portions has a receiving recess (86). The hydrophone cap (56) installs on this receiving recess (86). The portions (78, 82) each include a contact surface (94) which contacts the cable (16) when the portions (78, 82) fasten around the cable (16). The portions (78, 82) clamp around the cable (16) via screws (102). The contact surface (94) includes raised bosses (98) which securely grip the cable (16) by increasing contact pressure per unit area in a region of contact between the raised bosses (98) and the cable (16). In another feature, the portion which contains a receiving recess (86) further includes a wire-clearance recess (90) and a wire passageway (106) between the receiving recess (86) and the wire-clearance recess (90).
