The manipulation head connects to a second end of the robotic apparatus. The articulated arm includes first and second actuators. The articulated arm and robotic apparatus have electric actuators controlled independently by a control system of the manipulator.

Abstract: A valve element selectively opens and closes a radial aperture and an axial hole in a drilling element for drilling mud circulation. The valve element includes a fixing portion allowing the valve element to sealingly fix to the drilling element at the radial aperture. A body has an inlet aperture and an outlet aperture, and a duct for putting the apertures in communication with each other, defining a path for the drilling mud. A plug selectively seals the inlet aperture. A first sealing element is positioned in a housing formed in the axial hole of the drilling element. A shutter pivoted to the body includes a second sealing element to selectively and sealingly close the outlet aperture. The shutter selectively and sealingly closes the axial hole by abutting against the first sealing element. The valve element is adapted to keep the outlet aperture of the body normally closed.

Abstract: A connection device for connecting a secondary drilling fluids circuit to a drilling element includes a radial aperture. A central body has a first connection portion forming a sealed connection to the secondary circuit. A second connection portion forms a sealed connection to the radial aperture and an intake duct conducts drilling fluids. A clamping system connects the connection device to the drilling element. One opening device is adapted to selectively open and close the radial aperture by acting upon a valve assembly. One coupling device connects the opening device to the valve assembly. The opening device selectively opens and closes the radial aperture by acting upon an obstructor of the valve assembly through rotary movement. The coupling device couples to a clamping element in the obstructor to transfer the rotary movement of the opening device to the obstructor to selectively and securely open and close the radial aperture.

Abstract: A method of assembly is for a string of drilling elements for deepwater drilling. Each drilling element includes an axial through hole, through which drilling mud can flow, and two connection portions for connecting it in series in the string. The method includes assembling a lower portion of the string, assembling a first drilling element with other drilling devices to create a first section of the string. These steps are repeated until the lower portion is proximate the blowout preventer or the bottom. Assembly of second drilling elements begins while executing a drilling cycle for creating at least a second section of the string. The assembly step is repeated until the second section extends equal to a desired drilling depth. After assembling the lower portion and before assembling the first drilling element, a third drilling element is assembled, which includes an obstruction element for preventing backflow in the string.

The second sub-circuit and the first sub-circuit are independent, and the second sub-circuit is removable from the collector circuit.
