Abstract: The invention relates in general to pipe handling apparatus to position pipe through a range of horizontal and vertical positions. In one embodiment a pipe handling apparatus comprises a longitudinal base having a longitudinal axis, a boom carrying member slidably mounted to the longitudinal base for axial movement there-along, member actuating means operable to move the boom carrying member axially relative to the longitudinal base, a boom supported by the boom carrying member, the boom having a trough adapted for receiving at least one section of pipe therein and boom actuating means operable to raise and lower the boom.

Abstract: A system usable with a pipe laying vessel, includes a support frame, such as a deck frame of the vessel, and a loader arm which is movable between a loading position and an upright position. The loader arm is provided with a pipe section manipulation system. A first clamping member is provided having a substantially fixed position with respect to the support frame. The first clamping member is operable between a clamped position for supporting the weight of the pipeline, and a released position for allowing the pipeline to be lowered. A second clamping member is movable between an upper position and a lower position. The second clamping member is operable between a clamped position for supporting the weight of the pipeline during movement from the upper position to the lower position, and a released position for moving the second clamping member from the lower position to the upper position.

Abstract: An apparatus and method for handling a tubular pipe on a rig floor. In one embodiment, the apparatus includes a base, a track coupled to the base portion and a pair of arms slidably disposed along the track.

Abstract: A system for adjusting the height of a boom on a pipe handling apparatus. A cavity is formed in the base between proximal and distal ends. The boom is nestable in said cavity and has a distal end guided along the base. A pivoting member is pivotally coupled to said boom for raising a proximal end for positioned adjacent a work floor for handling of pipe therebetween. A plurality of ports are arranged along the boom at a pre-determined spacing. A plurality of ports are is similarly arranged along the same predetermined spacing along the pivoting member. The spacing of the boom and arm ports is such that a hinge pin can engage any one of corresponding pairs of boom and arm port when the boom is lowered to nestle inside the cavity as each boom port corresponds with an arm port.

Abstract: A pipe handling apparatus for raising and lowering pipe to and from a raised derrick work floor. The apparatus comprises a longitudinally-extending base, with a longitudinally-extending cavity therein. An elongate, longitudinally-extending boom member is provided, which is adapted for raising out of and nestable positioning in such cavity. The boom member has a longitudinally-extending trough therein on an upperside surface thereof, adapted to receive at least one section of pipe. At least one arm member is coupled to the boom member for raising a proximal end of such boom member. A pipe ejection assembly, integrated into said boom, is operable as the boom lowers into the cavity for the purpose of laterally ejecting pipe from the trough. The ejection assembly is adaptable for uni-directional or bi-directional ejection. Motive means are provided to permit powered movement of the ejector members when the boom is nested.

Abstract: In the work crystal orientation adjusting method, the crystal orientations of a work 22 in the rotational direction and in the horizontal direction thereof are measured by an orientation measuring device 76. In accordance with the measured value of the crystal orientation of the work 22 in the rotational direction, the work 22 is rotated about the axis thereof to thereby adjust the crystal orientation of the work 22 in the rotational direction. On the outer surface of the work 22, there are put marks M1 and M2 indicating reference positions for adhesion of an auxiliary plate B which is used to cut the work 22. The auxiliary plate B is adhered to the outer peripheral surface of the work 22 based on the marks M1 and M2. A work mounting plate 53 is mounted onto a support base 40 to thereby support the work 22 on the support base 40.
