Method and apparatus for deployment of ocean bottom seismometers
First Claim
1. An apparatus for deployment of ocean bottom seismic data receivers, said apparatus comprising:
- a. a remotely operated vehicle; and
b. a carrier attached to said remotely operated vehicle, wherein said carrier is disposed to carry at least two ocean bottom seismic data receivers removably secured therein,c. said carrier further comprising a frame and at least two separate conveyors, each housed within said frame, wherein said plurality of receivers can be disposed on said conveyors,d. wherein each of said conveyors is defined along a linear path and is disposed to move receivers along its respective linear path, wherein each linear path has a first end and a second end and extends between its first end and second end.

Abstract
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 may include a movable conveyor or fixed parallel rails or a barrel. The structure includes a discharge port on the frame and a discharge mechanism for removing and retrieving the receivers. A method for deployment and retrieval of ocean bottom seismic receivers includes the steps of loading a carrier with a plurality of receivers, attaching the carrier to an ROV, utilizing the ROV to transport the carrier from a surface vessel to a position adjacent the seabed and thereafter utilizing the ROV to remove receivers from the carrier and place the receivers on the seabed.
