Abstract
Drill pipe handling apparatus comprises a ramp (1) along which pipes (8) can be moved between a drilling derrick and a catwalk (3) next to a storage area. First and second support devices (4,5) are mounted on the catwalk so as to support a pipe on the catwalk and are provided with mechanical drive means to move the pipe along the catwalk. A mechanical handling device (6) is provided to move pipes between the catwalk and the storage area. <IMAGE>
Description
SPECIFICATION
Pipe handling apparatus
This invention relates to pipe handling apparatus.
The conventional procedure on a drilling platform is as follows.
Subsequent to pulling by the drilling crew on the drill floor the pipes have a thread protector cap screwed on to one end. The pipes are then lowered down a ramp towards a catwalk under restraint from a winch cable clamped to the collar end of the pipe and operated by a winchman at the head of the ramp. As the pipe reaches then advances along the catwalk, two loose rollers are inserted and the pipe takes up a horizontal position resting on the two rollers. The restraining clamp is then released. The pipe is manually propelled along the catwalk to the correct position and pushed laterally off the two loose rollers on to timber stringers which form the runners for the pipe storage area.
After the screw threads have been inspected the pipes are grouped in sling batches of eight and then lifted by crane into a storage bay.
There are a number of problems with this procedure. When the pipes are slid down the ramp the thread protector cap impacts onto the catwalk. If the speed of descent of the pipe is high this impact can be severe and can dislodge or cross-thread the protector cap.
This is one of the main causes of thread damage to the pipe.
The pipe has to be moved along the catwalk by hand, requiring two or three men to manhandle it.
The lifting and stacking of the pipes, by crane, is difficult and dangerous in high winds because the pipe loads can start to spin once lifted.
According to the present invention there is provided drill pipe handling apparatus comprising an inclined ramp along which pipes can travel between a drilling derrick and a catwalk, a first pipe support device mounted on the catwalk and movable along the length of the catwalk arranged to receive a lower end of a pipe from the ramp and to space said lower end above the catwalk, and a second pipe support device mounted on the catwalk and movable along the length of the catwalk and arranged to support the pipe at a position spaced apart from the first pipe support device.
Preferably, drive means are provided to lift a pipe up the ramp from the catwalk to the drilling derrick and to lower a pipe from the drilling derrick to the catwalk.
The drive means for lifting and lowering a pipe may be a winch or a hydraulic ram.
Preferably also, the first and second pipe support devices run on rails and are movable by means of mechanical drive means.
The mechanical drive means may be in the form of a winch.
A mechanical handling device may be provided to move the pipe from the first and second support devices off the catwalk into a storage area.
An embodiment of the present invention will now be described, by way of example, with reference to the accompanying drawings, in which:
Figure 1 is a side view of pipe handling apparatus in accordance with the present invention;
Figure 2 is a side view of the pipe lifting and stacking apparatus for use in conjunction with the pipe handling apparatus of Fig. 1; and
Figure 3 is an end view of the apparatus of
Fig. 2.
Referring to Fig. 1 of the drawings, pipe handling apparatus comprises a ramp 1 which runs between a drill floor 2 and a catwalk 3.
A wire rope driven pipe support dolly 4 is slidably mounted in steel guides under the catwalk 3. A pipe support roller 5 is also mounted on the catwalk. A pair of power operated fingers 6 are provided to move pipes on and off the catwalk 3. A winch 7 is provided to lift drill pipes 8 on and off the drill floor 2.
The operation for laying down pipes 8 is as follows.
A pipe 8 is attached to the winch 7 and swung into position A by a winchman so that it can begin to slide down the ramp 1. The pipe 8 is then lowered down the ramp 1 so that it takes up position B with its lower end resting on the support dolly 4. The winchman the operates the controls to move the dolly 4 along the catwalk until the pipe 8 takes up position C. The winchman can then disconnect the winch 7. The controls are then activated to move the dolly 4 towards the far end of the catwalk 3 allowing the pipe 8 to continue on its downward path on the ramp 1. The support roller 5, which is activated by the same wire rope as the dolly 4, emerges from under the ramp 1 to act as a cradle for the free end of the pipe 8. When the dolly 4 reaches the end of its travel the pipe 8 is held in position D, a horizontal position above the level of the catwalk 3.
When the dolly 4 reaches the end of its travel it activates a limit switch which causes the power operated fingers 6 to operate and push the pipe 8 off the dolly 4 and roller 5 down two short ramps to the storage area for inspection and stacking. The pipe 8 also activates a relay which causes the dolly 4 and roller 5 to return to their starting positions ready to collect the next pipe 8. The relay also returns the fingers 6 to this start position.
Two sets of fingers 6 are provided one set on either side of the catwalk 3 so that a pipe 8 can be pushed off to either side.
The pick-up operation for pipes, that is taking pipes from the storage area to the drill floor 2 from the storage area, is simply the opposite of the lay-down procedure.
A pipe 8 on the storage area is rolled into position next to the catwalk 3 and the fingers 6 operated to push the pipe onto the dolly 4 and roller 5. The dolly 4 then provides an end thrust which propels the pipe 8 up the ramp 2 to the top where the winchman attaches a hoisting collar and lifts the pipe. The dolly 4 then returns to the other end of the catwalk 3 to await the next pipe 8.
All the moving parts for the apparatus are located out of sight within the structure of the catwalk. The only moving parts visible on the top surface are the dolly 4, the roller 5 and the fingers 6.
As an alternative to the use of a winch for moving the pipe 8 up and down the ramp 1 a hydraulic ram can be provided, positioned at the base of the ramp 1, which pushes the pipe 8 up the ramp to the drill floor 2 from the catwalk 3 or lowers the pipe 8 from the drill floor 2 to the catwalk 3. The use of a hydraulic ram means that there is less need to have winch cables suspended above the working area.
Referring now to Figs. 2 and 3 of the drawings, these show lifting and stacking apparatus for use in the storage area.
The apparatus comprises a gantry 10 which runs on rails 11 along the sides of the storage area. The gantry 10 is provided with hooks 12 which allow it to lift single pipes or bundles of pipes from floor level into a storage bay between stanchions. The particular travelling portal frame straddle gantry 10 which is illustrated is capable of lifting an eight pipe bundle over the top of a two metre high stanchion.
The apparatus is capable of working in high winds, unlike the conventional cranes, but can be withdrawn to one side of the storage area when not required to allow cranes to be used without obstruction.
Modifications and improvements may be made without departing from the scope of the invention.
