Abstract
Apparatus and methods include a parking system for a drilling rig. The parking system includes a first track portion extending along a pathway between a well center and a V-door on a drilling rig and a second track portion extending in a transverse direction relative to the first track portion. A trolley is configured to carry a racking device and move along at least a portion of the first track portion and the second track portion between a position in the pathway between well center and the V-door on a drilling rig and a position offline and out of the pathway between well center and the V-door on a drilling rig.
Claims25
An apparatus comprising:
- a first lower track portion extending along a pathway between a well center and a V-door on a drilling rig;
- a second lower track portion extending in a transverse direction relative to the first lower track portion, the second lower track portion extending to a position offline relative to the pathway between the well center and the V-door on the drilling rig;
- a curved lower track portion disposed between the first lower track portion and the second lower track portion;
- a lower trolley configured to carry a racker device, the lower trolley coupled to a lower portion of the racker device and configured to move along at least a portion of the first lower track portion, the second lower track portion, and the curved lower track portion between a position in the pathway between the well center and the V-door on the drilling rig and a position offline and out of the pathway between well center and the V-door on the drilling rig;
- a first upper track portion extending along the pathway between the well center and the V-door on a drilling rig;
- a second upper track portion extending in a second direction transverse to the pathway, the second upper track portion extending to a position offline relative to the pathway;
- a curved upper track portion disposed between the first upper track portion and the second upper track portion;
- and
- an upper trolley disposed at an upper portion of the racker device, the upper trolley configured to move along at least a portion of the first upper track portion, the second upper track portion, and the curved upper track portion, wherein the racker device extends between the lower trolley and the upper trolley.
A method of installing a parking system for a racker device on a mobile drilling rig, comprising:
- installing a first track portion extending along a pathway between a well center and a V-door on the drilling rig;
- installing a second track portion extending in a transverse direction relative to the first track portion, the second track portion extending to a position offline relative to the pathway between the well center and the V-door on the drilling rig;
- installing a curved track portion connecting the first track portion and the second track portion;
- attaching a trolley to an upper portion of the racker device;
- and
- attaching the trolley to the first track portion, the second track portion, and the curved track portion so that the trolley can move between a position in the pathway between the well center and the V-door on the drilling rig and a position offline and out of the pathway between the well center and the V-door on the drilling rig.
An apparatus comprising:
- a first track portion extending along a pathway between a well center and a V-door on a drilling rig;
- a second track portion extending in a transverse direction relative to the first track portion, the second track portion extending to a position offline relative to the pathway between the well center and the V-door on the drilling rig;
- a curved track portion disposed between the first track portion and the second track portion;
- and
- an upper trolley configured to carry a racker device, the upper trolley coupled to an upper portion of the racker device and configured to move along at least a portion of the first track portion, the second track portion, and the curved track portion between a position in the pathway between the well center and the V-door on the drilling rig and a position offline and out of the pathway between the well center and the V-door on the drilling rig.
