Abstract: A system for managing replacement components for equipment having a plurality of components each with a limited useful life has a computer with a processor. The system includes a computer program module for defining a duty profile comprising a plurality of usage cases for the equipment, each usage case involving two or more of the plurality of components and specified operating conditions assumed to be experienced by the involved components during the execution of each of the usage cases. There are also a computer program module for determining a theoretical useful life for each component involved in a duty profile, the theoretical useful life being based on component useful life data under the specified operating conditions; and sensors for determining and monitoring the occurrence of equipment operation corresponding to a usage case and measuring the actual operating conditions experienced in the operation and the number of such operations.

Abstract: A device for placing pipes (5′) into a case (1) and taking pipes (5) out therefrom, wherein the pipes (5) are placed in stacks (2, 3, 4) each with one pipe across, and wherein the stacks are supported laterally by supports (6, 7, 8, 9) projecting upwardly from the bottom of the case (1). The bottom of the case 91) is provided with apertures (10, 11), and the case (1) is carried by a tilting device (13) capable of raising and lowering the case 91), respectively, and of turning it about an axis (14) parallel to the pipes (5) within the case (1), to take an unloading position and a loading position, respectively, wherein the supports (6, 7, 8, 9) are nearly horizontal, flushing with a substantially horizontal support for pipes (5), and wherein a pushing device (16) is adapted to be guided through the apertures (10, 11) in the nearly vertical bottom of the case (1), in order to push pipes (5) laterally out of the case (1), upon said support, which may be a conveyor belt or another conveyor (12).

Abstract: A device serves to interconnect pipes (3) to form a casing (1). A new pipe (3) to be added to the top of the casing (1), is suspended from an elevator (4) assigned to a drawworks, the latter being assigned a top drive (7) above the elevator (4). The device comprises a tubular hydraulic telescopic (device (9, 10), one end thereof being connected to the output shaft (8) of the top drive (7), the other end thereof being provided with a catcher (11) adapted to catch, raise and rotate the pipe (3). The catcher (11) is adapted to be guided into the pipe (3) and to be expanded to rest against the pipe and, thus, to establish an internal friction connection.
