A deployment method and system for ocean bottom seismometers (OBS) includes providing a plurality of circular shaped, wireless, self-contained OBS units. The circular shaped OBS units are loaded into a carrier and transported from a surface vessel to the ocean floor where a remotely operated vehicle (ROV) is utilized to individually place the plurality of circular OBS units on the ocean floor. Placement of each OBS unit is accomplished by utilizing suction mechanism attached to a robotic arm. The suction mechanism is defined about an axis and employs a suction cup to individually engage each circular shaped OBS unit so that the suction mechanism is coaxially aligned with the OBS unit, and move the OBS unit from a first location to the ocean floor.

The deployment method for deploying seismic data acquisition units into shallow water from the deck of a vessel provides for deploying a cable into the water. Seismic data acquisition units are moved from a storage location on the vessel to a position adjacent the cable. In one embodiment, a unit is accelerated to the approximate speed of the cable, at which point the unit is attached to the cable and released into the water. In another embodiment, cable deployment is interrupted while a unit is attached, after which, cable deployment is resumed.
摘要:
A marine seismic exploration method and system comprised of continuous recording, self-contained ocean bottom pods characterized by low profile casings. An external bumper is provided to promote ocean bottom coupling and prevent fishing net entrapment. Pods are tethered together with flexible, non-rigid, non-conducting cable used to control pod deployment. Pods are deployed and retrieved from a boat deck configured to have a storage system and a handling system to attach pods to cable on-the-fly. The storage system is a juke box configuration of slots wherein individual pods are randomly stored in the slots to permit data extraction, charging, testing and synchronizing without opening the pods. A pod may include an inertial navigation system to determine ocean floor location and a rubidium clock for timing. The system includes mathematical gimballing. The cable may include shear couplings designed to automatically shear apart if a certain level of cable tension is reached.

A deployment and retrieval apparatus for ocean bottom seismic receivers, the apparatus being a remotely operated vehicle (ROV) having a carrier attached thereto and carrying a plurality of receivers. The carrier includes a frame in which is mounted a structure for seating and releasing the receivers. The structure includes one or more movable conveyors disposed to move receivers along a linear path relative to the frame in order to discharge and retrieve ocean bottom seismic receivers.
