Abstract: A method for manipulating tubulars for subterranean operations including providing a first tubular at an initial position, wherein in the initial position the first tubular is in a substantially horizontal position and a proximal end region of the first tubular is position on a predetermined vertical axis, engaging the first tubular at the proximal end region with an engagement head, and lifting the first tubular at the proximal end region along the predetermined vertical axis and rotating the first tubular to change a position of the first tubular from the substantially horizontal position to a substantially vertical position, wherein in the substantially vertical position a longitudinal axis of the first tubular has an angular variation with respect to a predetermined vertical axis of not greater than about 5 degrees.

Abstract: A drilling-pipe handling apparatus and a method for handling drilling-pipes in a drilling rig, and is concerned particularly with apparatus and a method for racking drilling-pipes in an oil drilling rig. The pipe handling apparatus includes a pipe engaging portion, a movable positioning unit for moving the pipe engaging portion, and a mounting member for mounting the apparatus on a leg of a drilling mast.

Abstract: A drilling derrick (2) comprises a lower section (4) and an upper section (6) separated by a racking module (8). The lower section (4) of the derrick (2) is constructed from a number of sections of metal scaffolding (10). The upper section (6) of the derrick (2) is constructed from a similar number of metal sections (12).
