Notes: • Torque figures preceded by an asterisk (*) indicate that the weaker member for the corresponding outside diameter (OD) and bore is the BOX. For all other torque values the weaker member is the PIN. • In each connection size and type group, torque values apply to all connection types in this group, when used with the same drill collar OD and bore, i.e. 2 3/8 API IF, API NC26 and 2 7/8 Slim Hole connections used with 3 1/2 X 1 1.4 drill collars all have the same minimum make-up torque of 4600 ft-lb, and the BOX is the weaker member. • Stress relief features are disregarded for make-up torque. 1
Basis of calculations for recommended make-up torque assumed the use of a thread compound containing 40-60% by weight of finely powdered metallic zinc or 60% by weight of finely powdered metallic lead, with not more than 0.3% total active sulfur (Reference the caution below.) applied thoroughly to all threads and shoulders. 2
Normal torque range is tabulated value plus 10%. Higher torque values may be used in extreme conditions.
Make-up torque for 2 7/8 PAC connection is based on 87 500 psi stress and other factors listed in footnote 1.
Make-up torque for H-90 connection is based on 56 200 psi stress and other factor listed in footnote 1.
CAUTION: Thread compounds made according to API Bul 5A2 will produce excess make-up and are not recommended for use on rotary shouldered connections.
This information has been duplicated in its entirety from API RP 7G Table 14 and API Spec. 7, Appendix F and is current as of the publication of this Manual. However, it is likely that the data will be updated several times during the life of a Top Drive unit. Consult API Recommended Practices or IADC Drilling Manual to be certain that this information is current.

Notes: • Torque figures preceded by an asterisk (*) indicate that the weaker member for the corresponding outside diameter (OD) and bore is the BOX. For all other torque values the weaker member is the PIN. • In each connection size and type group, torque values apply to all connection types in this group, when used with the same drill collar OD and bore, i.e. 2 3/8 API IF, API NC26 and 2 7/8 Slim Hole connections used with 3 1/2 X 1 1.4 drill collars all have the same minimum make-up torque of 4600 ft-lb, and the BOX is the weaker member. • Stress relief features are disregarded for make-up torque. 1
Basis of calculations for recommended make-up torque assumed the use of a thread compound containing 40-60% by weight of finely powdered metallic zinc or 60% by weight of finely powdered metallic lead, with not more than 0.3% total active sulfur (Reference the caution below.) applied thoroughly to all threads and shoulders. 2
Normal torque range is tabulated value plus 10%. Higher torque values may be used in extreme conditions.
Make-up torque for 2 7/8 PAC connection is based on 87 500 psi stress and other factors listed in footnote 1.
Make-up torque for H-90 connection is based on 56 200 psi stress and other factor listed in footnote 1.
CAUTION: Thread compounds made according to API Bul 5A2 will produce excess make-up and are not recommended for use on rotary shouldered connections.

The use of outside diameters (OD) smaller than those listed in the table may be acceptable due to special service requirements.
Tool Joint with dimensions shown has lower torsional yield ratio than the 0.80 which is generally used.
Recommended make-up torque is based on 72,000 psi stress.
In calculation of torsional strengths to tool joints, both new and worn, the bevels of the tool joint shoulders are disregarded. The thickness measurement should be made in the plane of the face from the ID of the counter bore to the outside diameter of the box, disregarding the bevels. 5 Any tool joint with an outside diameter less than API bevel diameter should be provided with a minimum 1/32” depth X 45º bevel on the outside and inside diameter of the box shoulder and outside diameter of the pin shoulder. 6
P=Pin limit, B=Box limit.
*Tool joint diameters specified are required to retain torsional strength in the tool joint comparable to the torsional strength of the attached drill pipe. These should be adequate for all service. Tool joints with torsional strengths considerably below that of the drill pipe may be adequate for much drilling service.
This information has been duplicated in its entirety from API RP 7G Table 10 and is current as of the publication of this Manual. However, it is likely that the data will be updated several times during the life of a Top Drive unit.

The use of outside diameters (OD) smaller than those listed in the table may be acceptable due to special service requirements.
Tool Joint with dimensions shown has lower torsional yield ratio than the 0.80 which is generally used.
Recommended make-up torque is based on 72,000 psi stress.
In calculation of torsional strengths to tool joints, both new and worn, the bevels of the tool joint shoulders are disregarded. The thickness measurement should be made in the plane of the face from the ID of the counter bore to the outside diameter of the box, disregarding the bevels. 5 Any tool joint with an outside diameter less than API bevel diameter should be provided with a minimum 1/32” depth X 45º bevel on the outside and inside diameter of the box shoulder and outside diameter of the pin shoulder. 6
P=Pin limit, B=Box limit.
*Tool joint diameters specified are required to retain torsional strength in the tool joint comparable to the torsional strength of the attached drill pipe. These should be adequate for all service. Tool joints with torsional strengths considerably below that of the drill pipe may be adequate for much drilling service.
This information has been duplicated in its entirety from API RP 7G Table 10 and is current as of the publication of this Manual. However, it is likely that the data will be updated several times during the life of a Top Drive unit.

Top Drive Console Operating Instructions Canrig Model 6027AC-939 Top Drive With WEG TGA 355B Motor Refer to Top Drive Console Illustration, Figure 3.1 TOP DRIVE LOCKOUT SWITCH (PB1) DEPRESSED
Shuts off all electrical power to the top drive and disables all Top Drive functions. Normal Top Drive operation.
EMERGENCY STOP SWITCH (PB2) DEPRESSED
Shuts off all electrical power to the top drive and disables all Top Drive functions by: tripping the VFD (Variable Frequency Drive)breaker on Canrig supplied VFD units tripping the feeder breaker at the CIP panel or Transfer panel. Normal Top Drive operation.
Revision October 2013
Canrig Model 6027AC-939 Top Drive OFF - AUX - ENABLE (SW1) OFF AUX
Disables operation of the Top Drive. Power is supplied to the Top Drive for auxiliary functions but no power is available to the Top Drive motor. There is a 5 second alarm test sequence when AUX is first selected. This position is normally used for tripping operations. The VFD (Variable Frequency Drive) is enabled making power available to the Top Drive motor. (DC motors have a purge delay of 15 seconds). Power is available for auxiliary functions. There is a 5 second alarm test sequence when ENABLE is selected. The Top Drive blower will start when the internal motor temperature reaches 30 º C and remain on as long as the internal motor temperature is above 20 º C. If the internal motor temperature drops below 20 º C, the blower will shut off. The Top Drive lube pump will start. The Top Drive lube cooler will start after a 30 minute delay. If the Top Drive has been OFF for less than 120 minutes, the cooler will start when the top drive is ENABLED. (When applicable) The TOP DRIVE ENABLE light will be continuously lit when the FVD is properly enabled. The TOP DRIVE ENABLE light will flash under the following conditions: FVD not properly enabled.Purge delay. Power is supplied to the rotary table. Power is supplied to the Top Drive for auxiliary functions but no power is available to the Top Drive motor.
The Top Drive will automatically shut down under the following conditions: Low air flow detected while the Top Drive is in ENABLE and the motor temperature exceeds 30 º C. Loss of the Top Drive Lube Pump Running status. If the drilling motor temperature reaches 356º F (180º C). The throttle can be zeroed and the top drive restarted ONE TIME. If the high temp continues for 10 minutes the top drive will shut down and cannot be restarted until the temperature reaches 310º F (155º C). A Torque Unwind sequence is performed before shut-down to slowly remove the torque from the drill string. See Torque Unwind Section for more information.

Subsection 3A: Top Drive Operation TOP DRIVE MODE JOYSTICK (JS1) Refer also to the Top Drive Mode Joystick Function summary page 8. Refer also to the DRILL-SPIN-TORQUE Control Summary (Table 1) on page 9 DRILL The speed is controlled with the hand throttle wheel (TH1). Forward & The torque is limited by the DRILLING TORQUE LIMIT which is Reverse displayed in units of ft-lb on the DRILL TORQUE LIMIT meter (M3) and can be adjusted with the DRILLING TORQUE LIMIT dial (TH2). SPIN Forward & Reverse
The speed is preset at approximately 30 RPM. The torque is limited to 3 000 ft-lb (4 000 Nm). Note that there are two spin joystick positions for each direction. One is maintained and the other will spring return to neutral. The maximum torque is limited by the MAKE-UP TORQUE LIMIT which is displayed in units of ft-lb on the MAKE-UP TORQUE LIMIT meter (M4) and can be adjusted with the MAKE-UP TORQUE LIMIT dial (TH3). The maximum Make-Up torque is 60 000 ft-lb (81 300 Nm) which is the maximum electric motor torque of 36 000 ft-lb (48 800 Nm) plus the maximum Torque Boost Make-Up torque of 24 000 ft-lb (32 500 Nm). Refer to Section 2 for the Torque - Amp correlations. The torque will ramp up to the MAKE-UP TORQUE LIMIT, hold for 1.5 seconds and ramp down. The joystick must be held in the “TORQUE FORWARD” position during the entire sequence. Should the joystick return to the spring default position, the ramp down will go immediately to zero torque. Currents above the continuous rating will be time limited by the PLC to 5-85 seconds depending on the current level. The maximum Break Out torque is 60 000 ft-lb (81 300 Nm) which is the limited electric motor torque of 30 000 ft-lb (40 600 Nm) plus the maximum Torque Boost Break Out torque of 30 000 ft-lb (40 700 Nm). Currents above the continuous rating will be time limited by the PLC.
** See Torque Boost Disclaimer at the end of Section 3 IMPORTANT: Do NOT rotate the top drive with drill string weight in the elevators. Serious damage to the rotary manifold may result.

Revision October 2013
DOWNWARD POSITIONING (OPTIONAL) An ACME NUT inside the STOP TUBE acts as the downward stop. Turning the COUPLING NUT will cause the STOP ROD to turn. As the STOP ROD turns, it changes the position of the ACME NUT. When the POSITIONING CYLINDER is extended, the Back-up Wrench will stop when the ACME NUT comes against the top of the STOP TUBE. There is a spring pin at the bottom of the STOP ROD to prevent the STOP ROD from disengaging with the ACME NUT.
Canrig Model 6027AC-939 Top Drive
Drilling Connection Sequence 1. Drill down the joint of pipe, bringing the Top Drive as close to the floor as possible by retracting the Back-Up Wrench and elevator Link Tilt to the over-drill position (70 degrees toward the hinge side of the elevators). For safety, keep the elevators as close to the floor as possible and keep personnel from standing below retracted elevators. See “Pipe Handler – Care and Usage”. 2. Raise the pipe off bottom and set the slips. 3. Stop circulation and close the Upper Well Control Valve (LWCV, remotely activated from the Top Drive console). 4. Lower the Back-Up Wrench (BUW) over the pipe tool joint and close the BUW Gripper. 5. Break out and spin out of the pipe using Torque Reverse and Spin Reverse functions. Open the BUW Gripper. 6. Option A, B, or C (detailed on the following page). 7. Move the link tilt back to center using the FLOAT setting. Use Extend/Retract feature for minor adjustments. 8. Continue to hoist the Top Drive until the pin of the pipe to be added is above the box of the pipe in the slips. 9. Lower the Top Drive to stab the pipe into the drill string at the floor. Activate Spin Maintain. Continue to lower to stab the Top Drive saver sub into the box of the pipe being added. Lower the BUW fully for this operation to provide a stabbing guide. 10. After stabbing, continue to lower approximately 6 inches. This will allow the floating quill to compensate for the thread advance. 11. Use a back-up tong on the pipe in the slips if there is insufficient string weight for the slips to hold the make-up torque. 12. Spin in and make-up both connections simultaneously using the Top Drive. The torque can be pre-set at the Top Drive console. Raise the BUW Gripper to its highest position. 13. Open the Mud Saver Valve or LWCV if used as a Mud Saver. 14. Commence circulation, hoist to allow removal of the slips, lower to bottom and proceed to drill. 15. The elevators may be optionally opened and the link tilt retracted slightly while drilling.

Drilling Surface Holes with Collars 1. Put a collar in the mousehole, install a Drill-Through Pick-Up sub (DTPU sub) and torque as required with the tongs. Pick up the collar in the elevators and stab it into the collar in the table. Stab in the Top Drive and make-up both connections to the limit of the saver sub connection. Torque the floor connection to the required torque with tongs. If the drill collar is too large for the mousehole, then install the DTPU sub and pick it out of the V-door ramp with the elevators.
Canrig Casing Nubbin
Machined from one piece of 4145H material, eliminating welds and areas for potential failure.
Has a urethane guide mounted on the pin end to assist in stabbing casing and help prevent threads from making contact during stabbing.
Designed with a shoulder that faces up to the casing collar when at the hand-tight position. This allows the casing to be rotated by the Top Drive during casing run and creates a seal for filling or circulating the casing.
With the Nubbin properly installed in the casing, the Top Drive can be used to hoist the casing.
The Nubbins allow the weight of the Top Drive to be applied to the casing when tight spots are encountered downhole.
The casing thread of the Nubbin will usually exceed the performance of the actual casing thread due to superior metallurgical properties and a thicker wall at the Nubbin pin.
All Nubbins are load rated and code stamped for traceability.
Revision October 2013
Subsection 3A: Top Drive Operation
Tripping Sequence: Into Hole 1. Tripping procedures are essentially conventional unless tight hole is encountered. 2. Lower the drill string with the elevators and set the slips. 3. Open the elevators, retract Link Tilt slightly and hoist the Top Drive to the racking board position. 4. Extend the link tilt. Keep the pipe handler at the desired orientation to tilt the links to the desired pipe presentation point at the racking board. Pipe handler orientation is controlled at the Top Drive console. Maximum link tilt angle is pre-set to avoid any possibility of the elevators hitting the racking board. 5. The derrickman positions a stand of drill pipe and closes the elevators. This step is approximately the same as conventional non-Top Drive tripping except that the links are tilted toward the racking board, which reduces derrickman effort and improves safety. Power elevators are optional. 6. Move the link tilt back to center using the FLOAT setting. 7. Continue to hoist the Top Drive until the pin of the pipe being added is above the box of the pipe in the slips. 8. Lower the Top Drive to stab the pipe at the floor. 9. Spin in and make-up the connection using the floor handling tools. 10. Hoist the drill string and open the slips. 11. Lower the drill string into the hole and repeat the procedure.
If tight hole is encountered at any time, set the pipe in the slips and lower the Top Drive, spin in and make-up to the connection on top of the pipe. Use the Back-Up Wrench on the pipe tool joint if there is insufficient string weight to restrain the torque in the slips. Initiate circulation and rotation. Ream as required.
Revision October 2013
Canrig Model 6027AC-939 Top Drive
Tripping Sequence: Out of Hole 1. Suitable elevators should be installed on the Top Drive. 2. Latch the elevators around the drill string and hoist (opening slips) to the racking board elevation. The link tilt can be used to latch the elevators. 3. Set the slips while gently lowering the string until all weight of the drill string is in the slips. 4. Break out the stand in the elevators from the string using the floor handling tools. 5. Hoist to “un-stab” the stand. 6. Extend the link tilt. 7. Position the pin end of the stand at the pipe set-back and lower the Top Drive to set the stand down. 8. The derrickman opens the elevator and racks back the top end of the stand. The link tilt reduces the required derrickman effort. 9. Lower the Top Drive. Ensure the pipe is clear of the Top Drive. Retract the link tilt in preparation to latch the elevators onto the next stand. 10. Repeat the procedure.
If tight hole is encountered at any time, set the pipe in the slips and lower the Top Drive, spin in and make-up to the connection on top of the pipe. Use the Back-Up Wrench on the pipe tool joint if there is insufficient string weight to restrain the torque in the slips. Initiate circulation and rotation. Ream as required.
11. After a stand is reamed out, set the slips. Close the Back-Up Wrench on the drill pipe and reverse Torque to break the connection. Break the stand at the floor and rack back using the elevators.
Revision October 2013
Subsection 3A: Top Drive Operation
Running Casing Using Side Door Elevators 1. Retract the link tilt and close the casing elevators around a joint of casing lying in the Vdoor. The elevators approach the casing from the top side. 2. Hoist the Top Drive and casing joint to clear the coupling in the slips. Select the FLOAT position for the link tilt. 3. Stab the casing. 4. Align the casing using the link tilt and pipe handler rotation. No man is required on the stabbing board. 5. Make-up the casing with a power tong in the usual manner. 6. Hoist the casing string and open the slips. 7. Lower the casing string into the hole, set the slips and open the elevators. 8. Repeat the above procedure.
The Top Drive can be equipped with a Canrig casing nubbin attached to the quill during the entire casing job. It will allow you to screw into casing at any time. You can then: Fill the casing with no spills Circulate the casing string Rotate the casing string Reciprocate the casing string Push down on the casing string with the weight of the Top Drive and blocks. Any combination of the above.
Casing nubbins incorporate a urethane stabbing guide for thread protection and make-up shoulder. Various sizes and thread types are available.
Revision October 2013
Canrig Model 6027AC-939 Top Drive
Jarring DISCUSSION: It is imperative that Top Drive users exercise care and caution when using a Top Drive during and after a jarring operation. RECOMMENDATION:
Due to the changing parameters of jarring operations (depth of hole, drill string, free point, type of jars, etc.), it is impossible to establish firm limits or guidelines for jarring with the Top Drive. Every situation will have to be evaluated on individual merits with due consideration of the costs of abandoning a well.
The use of an Accelerator tool or a similar device in conjunction with drilling or fishing jars can greatly reduce the jarring forces at the top drive. It can absorb shock waves that are generated while jarring and protect the pipe and top drive from damage.
Canrig advises against using surface jars whenever possible, as the risk of damage to the Top Drive will increase.
After any jarring operation, the Top Drive should be thoroughly inspected according to the following guidelines:
Perform a thorough visual examination of the Top Drive looking for any signs of damage.
Visually inspect the mud inlet piping.
Check all wire locked bolts for damage or broken wires. If broken wires are detected, re-torque the bolts according to the Capscrew Torque Values information in Subsection 4D of this manual and rewire. Replace damaged wires.
Check all external bolts and nuts that are not wired for tightness. Any bolts found to be loose should be removed, coated with Loctite 242 Threadlocker, reinstalled and re-torqued according to the Capscrew Torque Values information.
Check all guards, vents and covers for tightness.
Ensure that all safety cables are properly and securely attached.
Visually examine the inside of the junction box(es) for loose components.
Open the motor brush access cover and check that all bolts are tight and all brushes are correctly positioned. Also ensure that the condensation heater is secure.
Check that all electrical plugs are properly engaged and secured.
Check the seals at the bottom of the rotary manifold to ensure that they are properly in place.
The Top Drive load path is designed according to API Specification 8C; it can be treated in much the same manner as any API hoisting equipment. The main difference is that
Revision October 2013
Subsection 3A: Top Drive Operation the Top Drive has many accessories bolted on; these should be checked for loose bolts, etc. as described above.
Jarring operations can be done with the load connected either to the quill or the elevators.
Slipping and Cutting Drill Line
Preferred method to slip and cut line: a) Screw a joint of pipe or drill collar to the quill. b) Set the pipe/collar attached to the Top Drive unit in the slips. c) The traveling block must be laterally restrained. This can be done by retaining the block to the mast or Torque Guide or by using the block guides (if system is equipped with this feature). d) Proceed to slip and cut as per rig procedure.
Alternate method to slip and cut line: a) Ensure the drill string is not attached to the top drive. b) Install the lower shipping pins on the torque guide and lower the top drive gently onto the shipping pins. c) The traveling block must be laterally restrained. This can be done by retaining the block to the mast or Torque Guide or by using the block guides (if system is equipped with this feature). d) Proceed to slip and cut as per rig procedure.
Revision October 2013
Never apply more than the weight of the top drive and block on the shipping pins of the torque guide. NEVER have the drill string screwed onto the top drive when on the shipping pins.
Canrig Model 6027AC-939 Top Drive
Pipe Handler Care and Usage Proper use of the Handler Lock system and the Link Tilt system can greatly reduce the chances of an accident or personal injury. a) All elevators must be installed with the handles on the OPPOSITE side from the link tilt cylinders (refer to Figure 3.2). b) The link tilt is designed such that at the fully extended position, the elevators clear the racking board. It is recommended that this clearance be verified by passing the top drive slowly past the racking board with the links extended. There should be a minimum 2” of clearance between the elevator handles and the racking board. c) If there is insufficient clearance, position the link tilt clamps lower on the links to increase the clearance. d) The link tilt overdrill position (retracted) is used for drilling as low as possible before connections, allowing for maximum bit clearance off bottom when making a connection. e) When torquing against the Back-Up Wrench (BUW), the Handler Lock prevents rotation of the handler assembly due to the applied torque. It is important to avoid the hazard of inadvertent handler rotation with the elevator links retracted. f) When the links and elevators are retracted (in the overdrill position), keep personnel from standing below the elevators or in the path of elevator travel. g) When torquing against the BUW, always keep personnel clear of the swing radius of the links and elevators in case of inadvertent handler rotation. h) The driller should keep the links and elevators as close to center as possible when torquing against the BUW. This will minimize the swing radius of the elevators. i) The lock pin or locking dog mechanism should be magnetic particle inspected annually. j) The lock alarm should be tested daily. A fault can be simulated on a lock dog by closing the dog on a 1/8” dia. rod or making tooth tip to tooth tip contact when closing.
IMPORTANT: Do NOT rotate the top drive with drill string weight in the elevators. Serious damage to the rotary manifold may result.

Subsection 3A: Top Drive Operation
Torque Boost Disclaimer The Torque Boost values shown throughout the specifications and instructions are based on the pressure settings (+/- 10%) shown on the hydraulic schematic for this circuit @ 75F (24C). Any change in oil viscosity and/or wear on the hydraulic and mechanical components could cause reduced torque output. An increase in circuit back pressure will reduce differential pressure across the motor and cause a decrease in torque output.
Procedure For Field Testing the Torque Boost Output The following procedure should be used when it is required to measure or verify the torque being generated by the Torque Boost. This procedure is intended to minimize possible mechanical damages to the torque boost hydraulic motor that may result from backspinning the Torque Boost. Uncontrolled back-spin may cause cavitation and failure of the motor. It will be assumed for the purpose of writing this procedure that rig tongs are being used, however the procedure will still be the same if a torque cell or some other load sensing device is being used.
Proper Canrig and Rig safety procedures must be followed and a JSA held to reduce the risk of injuries on the rig floor from any ‘kick back’ of the rig tongs or movement of the Top Drive when the torque is released.
Ensure that the traction motor is disabled by either setting the Top Drive control switch on the Driller’s Console to ‘Aux’ or otherwise locking out the power to the motor. This is critical on AC drive systems since the drive would attempt to keep the quill from turning and would interfere with the torque measurements. Configure the rig tongs or other device to resist the quill movement. Engage and hold the Torque Boost in make-up. Once the torque measurement reading has stabilized, engage the Top Drive brakes. Release the Torque Boost. Engage and hold the Torque Boost ‘break-out’ function. Release the Top Drive brakes and then release the Torque Boost as soon as the torque measurement approaches zero.
The time between releasing the brakes and the torque measurement approaching zero may be fairly short if only a LWCV and a saver sub is used at the end of the quill. In this case, the Torque Boost will need to be released almost immediately after the brakes are released to keep the tongs from rotating backwards (if the tongs don’t release properly). If a length if drill pipe is being used at the end of the quill, the time before releasing the Torque Boost will be somewhat longer.

Canrig Top Drive Drilling System
Revision January 2009
Subsection 3B: Top Drive and Torque Guide Installation INITIAL INSTALLATION INSTRUCTIONS HOOK STYLE TORQUE GUIDE 1. With the mast laid down install the crown hanger lugs as per the crown hanger drawing. 2. Install the torque guide hanging slings and pins on the crown lugs. 3. Attach the hinge mount in the mast as per the crown hanger drawing. 4. Weld the service loop mount to the mast or the racking board as per the mast services drawing. 5. Add block adapter and bail if the hook is to be removed. (see fig 1) 6. Raise the mast per the mast manufacturer’s procedures. Attach the bridal lines to the bail pins if the hook is removed.
Fig 1 Attach the service loops to the hangoff point before telescoping up the top section of the mast.
Revision January 2009
Canrig Top Drive Drilling System 7. Bring the Top Drive in the shipping frame up onto the catwalk with the top of it facing the v-door. (See fig 2 & 3)
Revision January 2009
Subsection 3B: Top Drive and Torque Guide Installation
8. After scoping out mast, connect the bail to the hook. It is safer to do it now by bringing the block to the floor. If the Canrig block interface is used, the bail was added in step 5. (See fig 4)
Fig 4 9. Connect the lifting slings from the bail to the middle set of lugs on the shipping frame. 10. Secure a hold back line to the bottom of the shipping skid. (See fig 5)
Fig 5 Lightly tension both ends.
Revision January 2009
Canrig Top Drive Drilling System 11. Lift the Top Drive with the traveling block, pulling it up the v-door. Use the holdback line to make sure that the top drive does not touch the v-door but remain as close as possible, to limit the impact if the holdback line were to fail. (See fig 6 & 7)
Revision January 2009
Subsection 3B: Top Drive and Torque Guide Installation 12. Set the shipping frame on end, with the quill over well center. 13. Slowly release the weight from the blocks and disconnect the lifting sling from the bail and the shipping frame. The holdback line will be needed later to lower the shipping frame off the rig floor. 14. Lower the traveling block/hook down to the Top Drive and connect the bail to the upper links. 15. Terminate the electrical and hydraulic service loops to the Top Drive. 16. Pick up the weight of the Top Drive without lifting the transport skid. Then attach a nylon sling with the tugger line the front of the top drive to control tilt. 17. With the right amount of pressure between the block and the tugger, remove the top pin holding the torque guide section to the shipping frame. Next remove the bottom pin (the second pin is usually harder to remove, so it is safer and quicker to do it at the rig floor). The Top Drive should be hanging from the traveling block now. 18. Remove the lower shipping pins, which hold the Top Drive guide runners in place, from the Torque Guide section. 19. Hoist the traveling block until the Top Drive and Torque Guide section are high in the mast. Watch for interference on the sides and the back of the Top Drive and Torque Guide.
20. Attach a tugger to the top of the shipping frame and lower the frame to the catwalk. Use the holdback line to pull the frame out over the v-door. Before you lay the frame down attach the top (long) pin to it. The short pin will be used to pin the sections together so leave it at the floor. Move the shipping frame out of the way. 21. Place the torque guide sections on the catwalk. Ensure that the hook end is away from the v-door.
Revision January 2009
Canrig Top Drive Drilling System 22. Lifting either one or two sections (pinned together) at a time, use a tugger to pull the section to the rig floor. (See fig 8 & 9)
Rigging up single section
Rigging up dual section
Revision January 2009
Subsection 3B: Top Drive and Torque Guide Installation 23. Lower the top drive so the torque guide is just above the rig floor and line up the next torque guide section with the hook at the bottom of the top section. 24. Set the pin on the top of the lower section into the hook of the upper section. (See fig 10)
Fig 10 25. Lift the top drive until the lower section clears the rig floor. Do this slowly to prevent the torque guide section from snapping into place. 26. When sections are hanging vertical, drive in the two pins between the two sections. This will need to be done at height in the mast and precautions should be taken to minimize the hazards. When pins are installed make sure the safety wire is run through both of the quick links behind the sections so they do not get cut by the top drive runners. 27. Repeat lines 22 to 26 until all the sections are pinned together in the mast. Pay attention for obstructions in the mast while hoisting the torque guide into place.
Revision January 2009
Canrig Top Drive Drilling System 28. Raise the top drive and torque guide with the traveling block until the crown slings can be pinned into the top of the torque guide. (See fig 11 & 12)
29. Pin the hinge pin between the mount on the mast and the lug on the torque guide. (See fig 12) 30. Slowly lower the traveling block and top drive. The torque guide should be hanging from the crown slings. 31. Remove the upper shipping pins from the torque guide section. (See fig 13)
Revision January 2009
Subsection 3B: Top Drive and Torque Guide Installation
Fig 13 32. Attach the torque reaction/extend frame to the back of the Torque Guide, at the height specified in the torque reaction assy. This can be left attached for subsequent rig moves. (See fig 14)
Fig 14 33. Install the torque reaction/extend mount into the mast as per their installation instructions. 34. Connect the pin between the extend cylinders and the extend frame on the back of the torque guide. 35. Lower the Top Drive to the rig floor and adjust torque reaction stops to achieve well center.
Revision January 2009
Canrig Top Drive Drilling System INITIAL INSTALLATION INSTRUCTIONS TORQUE REACTION / EXTEND FOR THE CANRIG BEAM STYLE 1. If this is not the first rig-up steps 2 to 9 can be eliminated. 2. Assemble beam with clamp plates, stop tubes and cylinders on the ground if they are not already assembled. Hydraulic plumbing and valves can be added at this time as well. Refer to the torque reaction assembly drawing for details. (See fig 1)
Fig 1 3. Tack weld the mast mount lugs onto the back legs of the mast as per torque reaction / extend assembly drawing. Ensure the tack weld is strong enough to hold the beam in place but do not weld out at this time. (See fig 2)
4. With the mast in raised position, lift the torque reaction beam to the rig floor and position it behind the back legs. (See fig 3) 3-48
Revision January 2009
Subsection 3B: Top Drive and Torque Guide Installation
Fig 3 5. Lift the beam up to the mast mount lugs with the cylinders in their traveling position (pointing up) and pin the beam to the middle hole on the mast mount lug. Then install the other pin in the bottom set of holes. (See fig 4)
Revision January 2009
Canrig Top Drive Drilling System 6. Check to make sure the cylinders will clear the winch motors in the mast at the next girt up. If there is interference then the winch motor will need to be moved up or the torque reaction beam will need to be moved down. Before taking any action do step 6. (See fig 5)
Lower the mast over the drawworks to check the torque reaction will not hit the drawworks while the mast is rigged down. Lower the mast slowly the last few feet to make sure the torque reaction or the drawworks are not damaged if there is interference. If there is interference the mast mount lugs will need to be moved up on the legs. They should be moved up as little as possible (to keep the cylinders below the winch motors). If there is a large gap between the torque reaction beam and the drawworks you may want to lower the mast mount lug on the mast. (See fig 6)
8. With the measurements taken raise the mast back up and make adjustments to the mast mount lugs and/or the winch motors as required. 3-50
Revision January 2009
Subsection 3B: Top Drive and Torque Guide Installation 9. Complete the welds on the mast mount lugs as called for in the torque reaction assembly drawing. 10. Make sure the top section of the mast is raised up to its working position. 11. Install the torque guide as per its installation instructions. 12. With the bottom pins removed use a tugger to rotate the beam on the middle pins until the top pins can be installed. The cylinders should be inside the mast now. (See fig 7)
13. The torque reaction frame should be installed on the torque guide at the height specified in the torque reaction / extend assy. It may need to be adjusted vertically to line up with the cylinders and the guide sleeves on the beam. The frame may already be installed if this is not the first rig-up. (See fig 8)
Revision January 2009
Canrig Top Drive Drilling System 14. Pull the torque guide with the tugger line toward the v-door until the guide tube can be unpinned from its vertical position and swung down to its horizontal position and pinned in place. 15. The torque guide can then be moved back into position, making sure the guide tubes are in the guide sleeve on the torque reaction beam. (See fig 9)
Fig 9 16. Pin the cylinders to the torque reaction frame.
17. Move the top drive down close to the rig floor and adjust the stops for well center.
