Well apparatus
First Claim
1. Well apparatus comprising:
- a tower having sides and having vertical rails, two of said vertical rails defining an opening at one of said sides of the tower providing access to an internal operational area of the tower,a support for supporting well intervention, completion, testing, or drilling equipment,said support being attached to the tower and being movable laterally from a parked position on the tower, wherein in said parked position, said support does not occupy said operational area where the equipment is to operate on the well to allow the preparation of the equipment, and an operational position in the operational area, wherein the support is arranged to be lowered or lifted, anda guide mechanism for guiding the support so that as the support is lowered or lifted, the support is guided along a path involving lateral movement from the parked position to the operational position in the operational area,wherein the guide mechanism for guiding the support comprises a pair of upper arms pivotally mounted on the tower and a pair of lower arms pivotally mounted on the tower below the upper arms, and wherein one arm of each pair of arms is pivotally mounted to one of the vertical rails defining the opening, and the other arm of each pair of arms is pivotally mounted to the other of the vertical rails defining the opening thereby enabling the support to move between the parked and operational positions through the opening.

Abstract
Well apparatus comprises a tower, and a support for supporting well intervention, completion, testing, or drilling equipment, the support being attached to the tower and being movable laterally from a parked position on the tower, where preparation of the equipment can be carried out without occupying an operational area where the equipment is to operate on the well, and an operational position in the operational area, and the support being arranged to be lowered or lifted, the apparatus further comprising a guide mechanism for guiding the support so that as the support is - lowered or lifted it is guided along a path involving lateral movement from the parked position to the operational position in the operational area.

12. A method of executing well intervention, completion, testing or drilling, the method comprising:
-
preparing well intervention completion, testing or drilling equipment on a support attached to a tower while the support is in a parked position on the tower, the tower having sides and having vertical rails, two of said vertical rails defining an opening at one of said sides of the tower providing access to an internal operational area of the tower, wherein in said parked position, said support does not occupy said internal operational area of the tower where the equipment is to operate on the well during said preparation, and moving the support laterally while it continues to be attached to the tower to an operational position in the operational area through the opening at one side of the tower to provide access to said internal operational area, wherein the support is moved laterally by being lowered or lifted, and by guiding the support so that as it is lowered or lifted it is guided along a path involving lateral movement from the parked position laterally of the operational area to the operational position in the operational area, wherein the guiding is effected by a guide mechanism comprising a pair of upper arms pivotally mounted on the tower and a pair of lower arms pivotally mounted on the tower below the upper arms, and wherein one arm of each pair of the upper and lower arms is pivotally mounted to one of the vertical rails defining said opening and the other arm of each pair of arms is pivotally mounted to the other of the vertical rails defining the opening thereby enabling the support to move between the parked position and the operational position through the opening. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22)
