A racking assembly for receiving and storing at least one pipe. The racking assembly comprises a set back assembly including a selectively rotatable member having a plurality of radial slots sized for receiving a portion of the pipe(s) in sliding engagement, and a base for supporting the pipe(s). The base is coupled to the selectively rotatable member so as to permit mutual rotation. A barrier is located about a peripheral edge of the base, such that the setback assembly rotates relative to the barrier. The barrier is arranged to prevent the pipe(s) from moving radially from the base. The barrier has a gap sized to permit selective lateral movement of the pipe(s). Mutual rotation of the selectively rotatable member and the base permit alignment of the gap and a selected slot of the selectively rotatable member, and thus permits the pipe stands to be moved laterally into the setback assembly.

A system for delivering a downhole tubular from a rack at an oilfield surface to a rig floor thereat. The system includes a trough for accommodating the tubular that is slidably engaged with a lift frame in a sledded fashion. Thus, for delivery of the tubular, the trough may be sleddingly extended from the lift frame. That is, as opposed to a roller type of coupling between the trough and tubular, a sledded coupling is utilized that may require comparatively less maintenance and mobilization time. This may be particularly the case where lighter weight tubulars of less than about 1,000 lbs., preferably under about 500 lbs., are being delivered.

Methods are disclosed for handling cylindrical tubulars in a process that, in preferred embodiments, also performs cleaning, inspection and other operations on the tubular. The tubular is held stationary while it is rotated. During rotation of the tubular, internal and external cleaning systems, and data acquisition systems, pass up and down the length of the rotating tubular.

Alarm systems and methods for preventing improper lifting of tubular members

Номер: US20140099175A1
Автор: Mark Guidry
Принадлежит: Mark Guidry

Systems and methods for preventing improper lifting of tubular members are described, in which sensing devices are used to detect when a tubular reaches a selected position within a lifting device suitable for engagement, and/or to detect when a lifting operation is initiated that would exceed the capacity of a lifting device. Operators are engaged with the tubular member and provided with a preselected force corresponding to the weight of one or more tubular members, such that when the weight of a lifting operation exceeds the preselected force, an audible device may be actuated responsive to sensor output, to immediately alert individuals, such that the improper lifting operation may be halted. Similarly, an audible device may be actuated responsive to sensor output when a tubular member reaches a selected position within the lifting device, such that additional movement may be ceased.
