Abstract

See full text

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.
