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 remotely operated vehicle; and
a carrier attached to said remotely operated vehicle, wherein said carrier is disposed to carry at least two ocean bottom seismic data receivers removeably secured therein, said carrier further comprising a frame and a movable conveyor housed within said frame, wherein said plurality of receivers can be disposed on said conveyor,said movable conveyor comprising a plurality of spaced apart rollers around which is disposed a closed loop, elongated conveyor belt having an inner surface and an outer surface, the outer surface characterized by a width of sufficient breadth to support a plurality of receivers disposed along the length of said belt, said plurality of spaced apart rollers disposed to support the inner surface of said belt along its length.

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

12. A method of deploying ocean bottom seismic data receivers from the deck of a marine vessel into a body of water having a surface and a seabed, said method comprising the steps of:
-
a. removeably loading a plurality of ocean bottom seismic data receivers in a carrier; b. attaching said carrier to a remotely operated vehicle (ROV); c. launching said remotely operated vehicle from the marine vessel located adjacent the surface of the body of water; d. guiding the remotely operated vehicle with the attached carrier to a position adjacent the seabed; e. causing said plurality of receivers to be removed from said carrier and placed on the seabed; f. providing a wireless modem on a receiver and on said remotely operated vehicle; and g. utilizing said wireless modem to provide communication with said receiver and said ROV.
