Abstract: Streamers used in mapping strata beneath a marine body are described, such as in a flexible neutrally buoyant towed array. A streamer cable is described using polyurea, within a sleeve, where the polyurea demonstrates durability in the presence of extreme hydrodynamic forces at depths in the marine body. The sleeve optionally uses longitudinal directed, inward pointing ribs to distribute forces and to minimize expansion of micro-cracks. The polyurea is optionally made neutrally buoyant through the controlled dosage of hollow, flexible, and/or glass microspheres into the polyurea at time of polymerization. A stress relieving connector is optionally used to longitudinally join a first and second streamer section and/or to connect a streamer section to a streamer stabilizer.

Abstract: Various methods and apparatuses for facilitating cleaning of submerged geophysical equipment using sound waves transmitted at ultrasonic frequencies are disclosed. In some embodiments, one or more transducers may be configured to transmit sound at one or more ultrasonic frequencies. The sound at ultrasonic frequencies may be transmitted in the vicinity of submerged geophysical equipment, such as a sensor streamer towed behind a survey vessel. Obstructions (e.g., barnacle larvae) adhering to surfaces of the geophysical equipment may be loosened or removed altogether when ultrasonic transmissions occur within its vicinity. The transducers used to transmit the ultrasonic frequencies may be implemented in various ways, such as being attached to a remote operated vehicle, a cleaning unit, or as being an integral component of the geophysical equipment.
