INSTALLATION GUIDE CHAPTER 2: PRE-INSTALLATION ACTIVITIES RIG INSTALLATION AND MEASUREMENT To ensure that top drive installation progresses smoothly, complete a detailed rig measurement package before ordering equipment. Rig measurement packages are available from TESCO. Accurate rig measurement helps you do the following: Determine an equipment placement plan Determine the best method for installing the top drive Identify specialized equipment requirements, including the following: swivel bail clamps torque track hanging pad eye components and subs (top drive to drill string) service connection lengths and specific accessories air/electric safety interlocks torque arrest system components hose saddle hanging requirements mud hose connection standpipe extension Ask a qualified TESCO representative to help you complete the rig measurement package. This will help to ensure that the equipment will fit properly within your rig s configuration. POWER/SERVICE CONNECTION REQUIREMENTS Discuss the following items with a qualified TESCO representative before you request shipment of the top drive system: diesel fuel interface with rig fuel supply starter air supply from rig electrical power 480VAC 100 amp recommended (60 amp minimum) 60 Hz or 380 VAC 50 Hz 880026 REV 3 250TON HMIS 475HP TESCO CORPORATION, 2007 3

PRE-INSTALLATION ACTIVITIES INSTALLATION GUIDE The following figures illustrate the connection considerations to address before the top drive system arrives on location. Note: If the customer is providing the main power supply (interconnection package), consult TESCO. Figure 2-1: Power, air and fuel connections - option 1 Figure 2-2: Power, air and fuel connections - option 2 TESCO CORPORATION, 2007 250TON HMIS 475HP 880026 REV 3 4

INSTALLATION GUIDE PRE-INSTALLATION ACTIVITIES Electrical Considerations 1. Determine a location for the power unit. Note: If the rig configuration has not been finalized, select two possible locations for the power unit. The power unit should be placed on the same side of the rig as the standpipe. 2. Determine the distance from the 480V, 100 amp plug at the motor control centre (MCC) to the power unit. Note: The standard power cable length is 250 ft. (76.2 m). 3. Determine if any special equipment is required. Examples: penetration or plug boards. Note: This equipment is required if the power cables must pass through walls on their way from the MCC breaker to the power unit. 4. Determine if a cableway or suitable space is available to accommodate the power cable that starts at the MCC breaker and goes to the power unit. Note: If adequate space is not available, determine what materials would be required to protect the cables from the breaker to the power unit. Fuel Considerations If the top drive unit is equipped with an integrated generator, then the connection requirements for fuel and air should be considered. 1. Determine the location and type of the fuel supply. Note: The fuel connector line should be 1 in. minimum, and it should be able to supply enough fuel for the power unit s maximum consumption. The fuel return line should also be 1 in. minimum. For the Caterpillar 460 hp prime mover, maximum consumption is 21 gallons (U.S.) per hour (79.5 litres per hour) For the Detroit Diesel 475 hp prime mover, maximum consumption is 22.8 gallons (U.S.) per hour (86 litres per hour) 2. Determine the required length of the fuel line. Determine the route it will take from the fuel supply to the power unit. Note: Avoid routing the fuel line where it might become damaged or pinched. 3. Verify the quality of the fuel supply. Note: Poor fuel quality might require special treatment. For example, fuel line heaters might be required in areas where diesel fuel contains high levels of paraffin. Air Considerations If the top drive unit is equipped with an integrated generator, then the connection requirements for fuel and air should be considered. 1. Determine if the air supply is adequate. Note: 100 psi minimum with a 1 in. supply line 2. Verify the quality of the air supply. Note: If you are in an area with high humidity, then a moisture trap might be required to remove moisture from the starter s air supply. 3. Determine the required length and route of the air supply line. Note: Avoid routing the line where it might become damaged or pinched. If you place the air receiver close to the power unit, this might help it start more easily. 880026 REV 3 250TON HMIS 475HP TESCO CORPORATION, 2007 5

PRE-INSTALLATION ACTIVITIES INSTALLATION GUIDE EQUIPMENT INSPECTION (PRE-INSTALLATION) TESCO inspects all top drive equipment before shipping, however, some damage might occur while equipment is in transit. It is important to identify any shipping damage as quickly as possible. This allows you to make necessary repairs, order equipment replacements, and optimize system readiness. As part of a pre-installation equipment inspection, do the following: Check all shipping containers for damage. External damage may indicate damage to contents. Visually inspect all principle components for damage or missing parts. If the top drive system is shipped with fluid levels at full, check the fluid levels. Low fluid levels may indicate a leak in the hydraulic, cooling, or lubrication system. A sample equipment checklist is included in Appendix A: Pre-Installation Checklist. TESCO CORPORATION, 2007 250TON HMIS 475HP 880026 REV 3 6

INSTALLATION GUIDE CHAPTER 3: RIG UP PROCEDURE EQUIPMENT PLACEMENT Optimal Placement of the Power Unit The following diagram shows the optimal placement of the power unit. This placement is considered ideal for the following reasons: The power unit is located on the same side as the standpipe. The placement allows straight-line access from the cable reel to the roller saddle. The cooling fans are not obstructed. There is adequate space in front of and behind the power unit (15 ft.). There is working access for personnel around the perimeter (3 ft. on each side). Figure 3-1: HMI optimal equipment placement Although the location of the power unit depends on the rig configuration, it is important that you consider the factors discussed above when you place the equipment. If space is very limited, you can order an optional stacking kit to mount the hydraulic oil storage tank, cooler and cable reel on top of the prime mover, pump drive, and filter manifold. Note: If you require a stacking kit, you must specify this requirement well before the unit is shipped. 880026 REV 3 250TON HMIS 475HP TESCO CORPORATION, 2007 7

RIG UP PROCEDURE INSTALLATION GUIDE How to Place the Power Unit Components 1. Ensure the ground surface is level; remove any major obstructions. 2. Install rig matting or another secure material under the equipment location. Note: Ensure the rig matting extends far enough beyond the equipment to provide a walkway for outside service activity. 3. Use a crane or loader to place the prime mover on the rig matting. 4. Connect the following items: Connect This From Here To Here 37C electrical control cable Power unit Driller s panel Closed loop high pressure supply and return lines Hose reel Filter manifold Diesel fuel line Fuel source Prime mover Air line Air source Diesel engine starter 480VAC (or 600VAC) power electrical cable Power unit Master Control Centre (MCC) 5. Connect the auxiliary hydraulic fluid lines from the auxiliary quick-connectors to the hose reel control. Note: Auxiliary hydraulic power is required to spool off the service loop when you install the hose hanging saddle. Optimal Placement of the Hose Saddle The following illustration shows the optimal placement of the hose saddle. This placement is considered ideal because the hose saddle is situated as follows: High enough to prevent cables or hoses from landing on the rig floor when top drive is lowered: If the mast height is 100 ft.-125 ft. (30.5m-38.1m), it is 55 ft.-65 ft. (16.8m-19.8m) above the rig floor. Low enough to allow the top drive to reach the highest position in the mast without straining or damaging hoses, Where the service hoses will follow the mud (Kelly) hose and reduce the risk of the service hoses interfering with the overhead equipment as the top drive travels up and down the mast, and Where the hose will not be damaged during top drive operations. TESCO CORPORATION, 2007 250TON HMIS 475HP 880026 REV 3 8

INSTALLATION GUIDE RIG UP PROCEDURE Attach protective equipment to any points that might be subject to wear during top drive operations. Figure 3-2: HMI hose saddle placement For Triple: Service Loop: Approximately 60-65 ft. between top drive and hose saddle capture clamp For Double: Service Loop: Approximately 50-60 ft. between top drive and hose saddle capture clamp 100-125 ft. Hose Saddle: Mounted 55-65 ft. above drill floor (depending on racking platform height and sling length) Hose Saddle: Mounted 45-55 ft. above drill floor (depending on racking platform height and sling length) Standpipe Hose Power Unit: Located on standpipe side Although the arrangement shown here is considered optimal, placement of the cable roller saddle is determined by several factors: mast height racking platform height length of traveling equipment (drill string, compensator, blocks, and swivel) saddle hanging mechanism and configuration available hose length (standard hose length is 225 ft.(76.2 m) unless otherwise requested) power unit location How to Install the Hose Hanging Saddle and Service Loop TESCO recommends that you suspend the hose saddle from a pad eye attached to the racking platform. If no pad eye is available, wrap a sling around a secure beam at the racking platform. The hose saddle can be shackled to the sling and suspended from the beam. The total weight suspended from the sling or pad eye is The hose saddle includes a clamp that holds the service loop cable and hoses in place at the racking platform. The hoses and cable are clamped into the saddle at ground level, then the saddle is hoisted into position. Before you begin this procedure, you must calculate the length of service loop that will travel with the top drive. 1. Ensure that the auxiliary hydraulic fluid lines are connected to the hose reel control. Note: Hydraulic power is required to un-spool the service loop for connection to the hose saddle. 880026 REV 3 250TON HMIS 475HP TESCO CORPORATION, 2007 9

RIG UP PROCEDURE INSTALLATION GUIDE 2. Use a soft sling to bundle the end of the service loop. 3. Attach the bundled end to the cable of the floor tugger or loader. 4. Use the hose reel and tugger to lay out the length of the service loop that will travel with the top drive. Note: Measure the length of the service loop, starting at the hammer union hydraulic connectors. Keep the service loop tidy, and ensure the ends of all hydraulic hoses are as even with each other as possible. Figure 3-3: HMIS cable/hose saddle clamping location 1 - Hammer union hydraulic connectors 2 - Hose saddle When the hose saddle is in place, the hoses to the top drive should reach the rig floor, and approximately 3 ft. (.9 m) of hose should be lying on the floor. 5. When the correct length has been spooled off the reel, insert the hoses and cable in the cable/hose saddle capture clamp.

Note: Hoist the saddle slightly higher than its final position. Figure 3-5: Hoisting the hose saddle Figure 3-6: Positioning the hose saddle 880026 REV 3 250TON HMIS 475HP TESCO CORPORATION, 2007 11

RIG UP PROCEDURE INSTALLATION GUIDE 8. Install the hanging sling for the hose saddle at the racking platform. Note: Attach the hanging sling to the pad eye with a shackle, or wrap it around a suitable beam. 9. Use a shackle to attach the hose saddle to the hanging sling. Note: The hose saddle sling must be strong enough to hold loads of more than 2,000 lbs (907.2 kg). 10. Use the floor tugger or crane to lower the saddle until the weight transfers to the hanging sling. 11. Install a back-up safety sling around the hose saddle.! Caution: This back-up sling is considered critical safety equipment. 12. Lower the crane or floor tugger cable. 13. Attach the crane or floor tugger cable to the sling at the free end of the service loop. 14. Hoist the free end of the service loop to the rig floor and secure it in place until it can be connected to the top drive and driller's panel. 15. Bring the 160 ft. (48.8 m) 37C control cable, connected to the main panel on the power unit, to the drill floor. TORQUE ARREST SYSTEM Before You Install the Torque Arrest System Install a hanging pad eye in the crown before you install the torque arrest system. This pad eye must be designed and installed to support the hanging weight of the entire torque assembly (safe working load of 5,000 lb. (2,268 kg) plus the recommended safety factor for overhead equipment). The pad eye is typically placed 18 in. (45.72 cm) back from the crown cluster centre. It is easiest to install the pad eye when the mast is down. Discuss installation procedures with a TESCO representative as part of pre-installation activities.! Danger! Design and installation of the pad eye should meet or exceed all safety specifications for the operating area and operating conditions. A variety of stabilization devices can be used to hold the torque arrest system in place during operations. It is easiest to install the stabilization systems before raising the mast. TESCO CORPORATION, 2007 250TON HMIS 475HP 880026 REV 3 12

INSTALLATION GUIDE RIG UP PROCEDURE Torque Arrest System Components A standard torque arrest system includes the torque beam, T-bar, and the following torque track sections (typical). The number of torque track sections depends on the free working height of the mast and is shown on the application drawing supplied with the top drive system: one adjustable hanging sling one cable clamp mount and cable capture clamp one 18.5 ft. (5.6m) reversible, bolted, bottom torque track section three 18.5 ft. (5.6m) standard torque track sections one 10 ft. (3.1m) torque track section one 5 ft. (1.5m) torque track section The total length of the torque track sections is 91 ft. (27.7m).Obtain additional length by lengthening the top section hanging sling. Purchase additional torque track sections to accommodate larger masts. One 1.3 ft. (.4m) deflector section (bull nose) of torque track is included.! Caution: Never subject the deflector section to torque. Mount it below the torque beam only. The deflector section is always mounted at the bottom. Its tapered design assists in mounting the torque bushing onto the torque track. Torque Arrest System Configuration You must know the following before you can determine the torque track configuration: height of the hanging pad eye for the torque track, measured from the rig floor (A) position (height above rig floor) where the torque beam and T-bar will be mounted (B) length of the hanging assembly for the torque track, including hanging swivel, nut, and shackles (2.5 ft. minimum (.8 m) to 15 ft. (4.6 m) maximum) Note: Shorter configurations are safer and more practical. Note: Correct calculations will help ensure that the torque bushing will not come off of the torque tube when the blocks are fully hoisted to the crown. the location of any upper strongback that may interfere with the vertical hanging of the torque track Note: If the torque track is to remain in the mast during rig moves, match the torque track connections to the mast connections wherever possible. 880026 REV 3 250TON HMIS 475HP TESCO CORPORATION, 2007 13

RIG UP PROCEDURE INSTALLATION GUIDE Figure 3-7: Torque arrest system configuration A = Mast height from rig floor to water table (underside of crown) B = Height of T-Bar and anchor beam C = Clearance beneath torque track deflector (to be a minimum of 7 ft) D = Length of torque track hanging assembly E = Distance from top of travelling block down to top of torque bushing F = Distance from bottom of torque bushing down to bottom of elevator G = Stump height above rig floor How to Determine the Torque Track Configuration (where an application drawing is not supplied) Sketch and calculate the following on paper before you connect sections of torque track. 1. Place the bottom of the deflector section 8 ft-10 ft (ideally) above the drill floor, but no less than 7 ft (min) and no more than dimension F+G (max) to ensure it does not come off the bottom end of the torque track when it is in the lowermost position. 2. Place the bottom bolted section of torque track above the deflector section such that it coincides with elevation B. Note: Ensure that a suitable strongback for mounting the torque beam and T-bar is available somewhere along the length of the bolted section of torque track. Remember that the bolted section is reversible. 3. Stack the track sections (18.5 ft., 5 ft. and 10 ft. sections) until you reach 5 ft.-15 ft. (1.5 m-4.6 m), ideally, from the pad eye. Note: Dimension D is to be no more than dimenstion E to ensure that it will not come off the top end of the torque track when it is in the uppermost position. 4. Determine the length of hanging assembly required. Note: Ensure that the length of hanging assembly is incorporated into the calculation. TESCO CORPORATION, 2007 250TON HMIS 475HP 880026 REV 3 14

INSTALLATION GUIDE RIG UP PROCEDURE Sample Calculation If the mast height is 142 ft. (43.3m): 1. 142 ft. less 9 ft. (2.7 m) (height above rig floor for the deflector section) = 133 ft. (40.6 m) 2. 133 ft. less 2.5 ft. (.76 m) (minimum hang assembly length) = 130.5 ft. (39.8 m) 3. 130.5 ft. divided by 18.5 ft. = 7 full-length tracks; this does not include the deflector section. Torque beam desired height = 11 ft. (3.4 m) The rig up would be as follows: Track Part Qty Length (ft.) Total Length (ft.) Hanging Track 1 18.5 18.5 Standard Tracks 4 74 (18.5 x 4) 92.5 10 ft. section 1 10 102.5 5 ft. section 1 5 107.5 *Bolted section 1 18.5 126 Deflector 1 1.3 127.3 **Pinned Section Length or Hanging Assembly 1 Set to 6 feet 133.3 *The bolted track section would be run with the bolt section down, below the standard track sections and 10 ft. and 5 ft. sections. The deflector track section would be mounted below the bolted section. **Hanging assembly length should not be more than 1 ft longer than the height differential between the top of the travelling block to the top of the torque bushing. How to Install the Torque Arrest System Use this procedure to install the torque arrest track system. Refer to Figure 3-8 on page 19. 1. Ensure the hanging pad-eye for the torque track is installed in the crown. Note: Normal placement for a standard track is 18 in. back from the crown cluster centre. 2. Assemble the torque beam, T-bar, and T-bar clamp.! 142 (mast height) - 133.3 = 8.7 feet above the rig floor) Warning! Assemble the above with the T-bar at mid-length. This balances the assembly during lifting.the assembly should not be fully torqued, but it should hold the T-bar securely in place. 880026 REV 3 250TON HMIS 475HP TESCO CORPORATION, 2007 15

RIG UP PROCEDURE INSTALLATION GUIDE 3. Use the tugger to move the torque beam onto the drill floor and up to the lowest, most practical strongback beam. Note: Install the torque beam low in the mast. Attach it to a large beam anywhere between 10 ft. and 16 ft. above the drill floor. If you install it any higher, you might require additional stabilization below the torque beam. TESCO can supply additional stabilization, if required. 4. Use four clamps to mount the torque beam to the selected supporting beam. Note: On a permanent installation, you may weld the anchor beam clamp onto the mast. 5. Slide the T-bar to the most rearward position. 6. Use the calculation method described in How to Determine the Torque Track Configuration (where an application drawing is not supplied) on page 14 to calculate the required torque track section configuration. Note: When the torque track is suspended, the bottom of the deflector section should be 7 ft.-8 ft. off the floor. 7. When the torque track section rig-up is determined, set and secure the calculated hanging sling length.!! Caution: Torque sling bolt clamps to 230 ft lbs. Note: When you tighten the sling clamp bolts, ensure that the sling is compressed evenly along its length. It will take several repetitions to ensure that the clamping force is distributed evenly across all of the cable clamps. 8. Fasten the hanging sling plate to the top section of torque track. Note: Use a soft sling to hold the sling in place so that it will be easily accessible when the torque track is lifted to the hanging pad eye. 9. Use the rig floor tuggers to hoist the first track section up to the floor. Note: On most rigs, two full-length sections of torque track can be assembled on the ground before being lifted to the rig floor. If the rig is very small, you will have to bring the torque track lengths to the rig floor one at a time. Note: As the first section is installed, make up additional sections on the ground. 10. Lower the first track section through the rotary table or mousehole. Note: If the rotary table is too small to permit the torque track to pass through, use an alternate location on the rig floor. If no alternate location exists, mate the sections above the rig floor. 11. Lower the blocks and install two handling slings on the torque track. Note: Thread the slings through the block becket and attach them to the top track using the handling assembly for the torque track. Caution: Attach the top section of track such that the top portion of track extends above the blocks. This allows the hanging assembly to reach the pad eye without crowning out the blocks. 12. Place a ratchet strap around the top of the blocks and thread it around the torque track. 13. Use the ratchet strap to pull the blocks and track together. Note: This immobilizes the track section and keeps it hanging vertically as it travels up the mast. 14. Hoist the blocks until they support the weight of the torque track. 15. Remove the floor tugger. TESCO CORPORATION, 2007 250TON HMIS 475HP 880026 REV 3 16

INSTALLATION GUIDE RIG UP PROCEDURE! 16. Hoist the blocks until the bottom of the first section is 8 ft. above the drill floor. 17. Connect the floor tugger to the second section of torque track and hoist it to the rig floor. 18. Lower the second section of track through the rotary table or into the mousehole until it reaches the appropriate level for connecting to the upper section (which is currently suspended from the blocks). 19. Use chains to secure the second section in place, or place a strong bar through the back strap of the torque track. 20. Lower the blocks and upper section of track and connect the two sections. Bolt the sections together, ensuring a flush connection. Note: Coat all bolts with an anti-seize compound before installation. 21. Torque the bolts to 350 ft lbs. 22. Repeat steps 17. 21. until all sections are connected and supported by the blocks. Note: The last section that is installed is typically composed of the reversible bolted section, the deflector section and, if required, the two-foot track section. 23. Use a ratchet strap to secure the extend arms of the torque bushing in place. 24. Attach a tugger to the torque bushing and move the bushing onto the drill floor. Note: Ensure that the extend frame is down. 25. Position the torque bushing over hole centre. 26. Use the blocks to lower the assembled torque track and stab it through the torque bushing. 27. When the torque bushing is in position, pin it in place. Note: Ensure that the top drive pin ends are at least 8 ft. above the drill floor. If the torque bushing is too tight to move freely along the torque track, adjust the torque bushing by adding additional shim packs. To ensure a proper fit, periodically check the bushing during the first few days of operation. 28. After the torque bushing is installed, raise the blocks to the crown. 29. Connect the hanging assembly of the torque track to the pad eye. 30. When the hanging assembly is connected to the pad eye, lower the blocks until the weight of the track is transferred to the pad eye. Note: Do not remove the handling assembly yet.
