Deployment method for ocean bottom seismometers
First Claim
1. A method for deployment of ocean bottom seismometers (OBS) units on the ocean floor, said method comprising:
- a. providing a plurality of wireless, self-contained OBS units, each OBS unit defined about an axis and configured to be individually placed and positioned on the ocean floor,b. transporting said OBS units from a surface vessel to the ocean floor; and
c. utilizing a remotely operated vehicle (ROV) to individually place at least one of the plurality of OBS units on the ocean floor,d. wherein said placement is accomplished by utilizing a suction mechanism defined about an axis and having a suction cup to individually engage each OBS unit so that the suction cup mechanism is coaxially aligned with the OBS unit, and moving the OBS unit from a first location to the ocean floor, ande. wherein the OBS units are transported from the surface vessel separately from the ROV or the ROV wirelessly activates at least one functionality of the OBS units.

Abstract
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.

9. A system for deployment of ocean bottom seismometers (OBS), said system comprising:
-
a. a plurality of wireless, self-contained OBS units, each having an upper surface and each OBS unit defined about an axis and individually positionable; b. a carrier loaded with said OBS units; c. a remotely operated vehicle (ROV); d. a robotic arm having a distal end and a proximal end, said proximal end attached to the ROV; e. a suction mechanism attached to the distal end of the robotic arm, said suction mechanism defined about an axis and comprised of a suction cup disposed to engage the upper surface of an OBS unit so that the axis of the suction mechanism and the axis of the OBS unit are coaxial aligned, wherein the carrier comprises a mechanism to allow movement of the OBS units from a first end of the carrier to a second end of the carrier opposite the first end, the OBS units being removed from the second end utilizing the suction mechanism. - View Dependent Claims (10, 11, 12, 13)
