Abstract: An apparatus to remotely control the depth in the water of a marine cable, such as a streamer of seismic geophones or hydrophones towed behind an exploration boat during seismic surveys of submerged formations, and maintain the cable at a desired depth. The depth at which the cable is maintained may be remotely adjusted for a range of selected depths. A new and improved attaching mechanism for attaching the depth control apparatus to the cable is provided.
Abstract: An apparatus to control the depth in the water of a marine cable, such as a streamer of seismic geophones or hydrophones towed behind an exploration boat during seismic surveys of submerged formations, and maintain the cable at a desired depth. The apparatus includes structure to prevent damage from obstacles in the water and other imparing of performance. The apparatus includes other structure to improve performance characteristics in operation.
Abstract: An apparatus to control the depth in the water of a cable, such as a cable streamer of seismic geophones or hydrophones towed behind an exploration boat during seismic surveys of submerged formations, and maintain the cable at a desired depth while operating at reduced noise levels and with improved operating characteristics. The depth at which the cable is maintained may be adjusted for a range of selected depths.
