Canrig Top Drive Drilling System

2 Revision 03.12

INTRODUCTION: To improve the productivity and help eliminate safety hazards associated with the removal of the Wash Pipe nuts, CANRIG has designed a Wash Pipe removal tool that is safe, user friendly and more efficient. The tool consists of three parts, the coupling tool, the wrench tool and the retaining tool. DESCRIPTION:

1) Wash Pipe Coupling Tool: The coupling consists of a split tubular where both pieces are hinged by two pins on one side while the other side has two removable pins to open and close. The coupling has 4 lugs on each end which are designed to fit into the lugs on each of the upper and lower nuts. Each of the nuts has 5 lugs which indicate that only 4 lugs will make contact with the coupling. The coupling will fit between the two nuts as shown below.

Picture shows the 3” Wash Pipe Coupling with Nuts

Revision 03.12 3

2) Wash Pipe Wrench Tool The Wrench is designed to make-up and breakout the lower nut only. As shown below, the 3” Wash Pipe Wrench has four lugs and an opening that is large enough to fit around the Wash Pipe and then slid down to fit on the lower nut. On the other hand, the 4” Wash Pipe Wrench has 5 lugs, however two of the lugs are hinged to the main wrench to allow it to fit over the Wash Pipe before sliding it down to fit onto the lower nut. Both the 3” and 4” Wash Pipe Wrenches have an arm that will rest against the open window in the Bonnet when breaking out or making up the lower nut.

4” Wash Pipe Wrench 3” Wash Pipe Wrench

3) Wash Pipe Retaining Tool The wash pipe retainer tool (P/N DT12826) fits between the wash pipe and the quill, to prevent the wash pipe from sliding into the quill, once the lower nut is loose.

Operating Instructions

Sequence of operation – Removal of wash pipe: When attempting to remove an old wash pipe where the packing is worn out, it may very well be that the threads on the lower nut had lost tension. In this case, if you were to use the wash pipe coupling tool first, the lower nut will most likely break out before the upper nut does. Therefore, for the sake of saving time, it maybe more advantageous to tighten the lower nut using the wash pipe wrench prior to using the wash pipe coupling tool. CAUTION: a) The Torque Boost should NEVER be used when tightening the wash

pipe nuts due to the excessive torque that it generates. It maybe used for aligning the nuts lugs only.

b) The top and lower nuts have left hand threads c) Apply a liberal amount of anti-seize to the threads of both nuts prior

to tightening.

1. Install the wrench tool by fitting it around the wash pipe and then sliding it down to fit onto the lower nut.

2. Set the drilling torque limit to ZERO. Next, advance the throttle in FORWARD

direction to approximately 10 o’clock position.

3. To prevent the wrench arm from slamming against the side of the bonnet window, VERY SLOWLY increase the drilling torque to:

3” WP tool 4” WP tool 6000 Ft-lbs 8000 Ft-lbs

Once the proper torque has been applied for approximately 5 seconds, zero the

throttle and the drilling torque, and remove the wrench.

4. Align the top and bottom wash pipe nuts such that the lugs are in synchronization (i.e. will allow the coupling tool to be installed), by rotating the Top Drive with the torque boost Make-up or Break-out).

5. Remove pins from coupling tool to allow the tool to be opened

6. Pending wash pipe nut design you may have to remove the grease zirc before

installing the coupling tool.

7. Install coupling tool between the upper and lower wash pipe nut.

Revision 03.12 5

8. Close the coupling tool and insert the pins (removed in step 5).

9. For loosening of the upper wash pipe nut (do not fully unscrew it, until the wash pipe retainer tool has been inserted, see step 13), rotate the Top Drive reverse. This is accomplished by first setting the Drill Torque limit to ZERO. Now move the Joystick into the REVERSE position and advance the throttle to select very slow rotation (approx. 10 o’clock position). Next, very slowly increase the Drill Torque limit to the following limits:


Zero the torque limit and throttle, as soon as the nut breaks the connection. Make sure that the top nut is not fully unthreaded, as it will be used to hold the wash pipe in place until step 13.

10. Should the bottom wash pipe nut break before the top nut, remove the coupling

tool and perform steps 1 through 9, however, the make up torque for the lower nut should be increased to 7000 ft-lb and 9000 ft-lb for the 3” and 4” nuts respectively, otherwise proceed to step 11.

11. Remove the coupling tool and install the wrench onto the lower nut.

12. For loosening of the lower wash pipe nut, rotate the Top Drive in a reverse

direction. This is accomplished by first setting the Drill Torque limit to ZERO. Now set the joystick to REVERSE and advance the throttle to select very slow rotation (approx. 10 o’clock position). Next, very slowly increase the Drill Torque limit to:


Zero the throttle, as soon as the nut breaks the connection. Any further rotation can be done by repeating this step again until the lower nut is fully unthreaded.

13. Remove the wrench and install the wash pipe retainer tool (P/N DT12826)

between the wash pipe and the quill, to prevent the wash pipe from sliding into the quill, once the lower nut is loose.

14. Continue to loosen (unthread) the upper nut by hand until is completely free.

Remove the wash pipe assembly.

Sequence of operation – Installation of wash pipe

15. After the wash pipe assembly has been properly assembled, make sure that the threads of both the top and lower nuts have a liberal amount of anti-seize coating. Insert the wash pipe assembly into the Top Drive through the large


6 Revision 03.12

bonnet window and start both nuts (by hand) until at least two full turns of thread are engaged. Note: Both threads are LEFT-HAND.

16. Install the coupling tool (as per steps 4-8).

17. Set the drilling torque limit to ZERO. Next, advance the throttle in FORWARD

direction to approximately 10 o’clock position.

18. To prevent over-torquing, VERY SLOWLY increase the drilling torque in small increments to 1000 ft-lbs until the nuts shoulder up. If 1000 ft-lbs is not enough to make the nuts shoulder up, SLOWLY increase torque limit to 2000 ft-lbs until they do. Once the threads have fully shouldered up, SLOWLY increase the drilling torque as shown below:


Once the proper torque has been applied for approximately 5 seconds, zero the

throttle and the drilling torque, and remove the coupling tool.

19. Check wash pipe seals for any leak. If the seals are still leaking, repeat steps 17 and 18 (above) by slowly increasing torque limit by 500 ft*lbs above previous setting until seals are tight. Do not exceed the following maximum torque values:


If sealing of the wash pipe is not possible with the above maximum torque values, the packing may be defective and needs to be replaced with a new unit.

20. Once a proper seal has been accomplished, remove the coupling tool. This

concludes the installation sequence.
