    AUTOMATED POWER CATWALK

    The Automated Power Catwalk is used to move tubulars between the pipe rack area and the drilling floor. It consists of a Catwalk, Ramp and a Carrier assembly and a series of tubular movement devices. The unit is controlled by a computer through controls on the Control Console or from a Wireless Control. The Automated Power Catwalk, see Figure 1, has three folding hydraulic Pipe Racks and three Indexers on either side. The Automated Power Catwalk also contains the Hydraulic Power Unit and Control Console on the Drillers side, flare end. The Ramp is hinged to the Automated Power Catwalk and rotates up to rest on the drilling floor for operation. It is chained to the Rig Floor for safety. The Ramp has a Carrier Lift Winch mounted on the under side. The Carrier, see Figure 2, is used to carry tubulars to and from the drill floor. It is normally stored retracted flush inside the Automated Power Catwalk. When loaded with a tubular, the Carrier Lift Winch moves the Carrier up and down the Ramp. The Carrier has three Kickers and three Safety Pins on either side and includes the Skate and Skate Winch assemblies. The major components and layout are illustrated in Figure 1.

    3-6 Revision April 2011

    PIPE RACK There are three Pipe Racks, see Figure 3, mounted on either side of the Catwalk. Each Pipe Rack swings on a ball mount and is stowed for transport on a shipping support. A short chain secures the Pipe Rack to the shipping support. Cylinder Swing Wedges can be used to hold the Pipe Rack horizontally so it can be swung out 90 degrees for operation. The Wedges can be removed once the Pipe Rack Hydraulic Leg is extended to the ground and the Pipe Rack is supported.

    Figure 3: Pipe Rack The Pipe Rack Hydraulic Legs are operated from the Control Console or from the Wireless Control.

    The maximum capacity of each pipe rack is 5,000 lbs.

    Keep feet out from under Pipe Rack leg while swinging Pipe Rack

    out from or into transport position.

    INDEXERS There are three Indexers, see Figure 4, on both the Drillers side and the Off-drillers side of the Catwalk (Figure 1). Each Indexer has two hydraulic cylinders. Operating the outer cylinder lifts the outer end of the Indexer to roll tubulars in towards the Carrier. Operating the inner cylinder lifts the inner end of the Indexer to roll tubulars out of the Carrier toward the Pipe Racks. All of the outer or inner Indexer cylinders on a side of the Catwalk operate simultaneously with one lever. The Indexers may be operated in either direction (inner raise or outer raise) by pushing the appropriate lever in the desired direction on the Control Console or the Wireless Control.

    Figure 4: Indexer

    NOTE Indexers will NOT function when the Carrier is elevated or while

    the Skate is in operation.

    3-8 Revision April 2011

    SAFETY PINS There are three Safety Pins, see Figure 5, on each side of the Carrier. The Safety Pins are actuated by Hydraulic Cylinders. The Safety Pins prevent tubulars from rolling across the Carrier when loading, or rolling out of the Carrier when it is being raised or lowered. The Safety Pins extend automatically when the Carrier is elevated. The Drillers side or Off-drillers side Safety Pins can be operated manually when the Carrier is in the fully retracted position by using the Safety Pin toggle switches on the Control Console or the Wireless Control. These are labeled Locator Pin on the Wireless Control. All three Safety Pins on a side operate simultaneously. The Safety Pins can not be lowered unless the Carrier is fully retracted. The Safety Pins will automatically retract only when the Carrier is fully retracted into the Catwalk and none of the switches on the Control Console or Wireless Control are in the up position.

    Revision April 2011 3-9

    KICKERS There are three Kickers, see Figure 6, on each side of the Carrier. Hydraulic cylinders actuate the Kickers. The Kickers eject tubulars out of the center Carrier groove to either the Drillers side or the Off-drillers side. All Kickers on a side operate simultaneously with one lever. Pushing the appropriate lever on the Control Console or the Wireless Control operates the Kickers. When the Carrier is elevated out of the Catwalk or when the Skate is in operation the Kickers do not work.

    Always ensure that the Skate is not blocking any of the Kickers

    before operating the Kickers.

    SKATE The Skate, see Figure 7, runs the length of the Carrier and is powered by a hydraulic winch and cable. The Skate is operated from the Control Console or the Wireless Control. The Skate can be operated at any time when the hydraulic pump is on.

    Do NOT use the Kickers if the Skate is in the way.

    Do NOT run the Skate into the stop plates located under the top

    Carrier plate near each end of the Carrier. This will cause damage to the Skate assembly and shorten the life of the skate cables.

    Revision April 2011 3-11

    CARRIER LIFT WINCH The Carrier Lift Winch is located under the Ramp, see Figure 8. Cables from the Winch Drum travel up the under side of the Ramp, over two guide sheaves and down the front side of the Ramp in the protective slots. The cables pass under the Cable Guide Block on the front of the Carrier and attach to the Cable Attachment Block located about 2/3 down the length of the Carrier. The Carrier Lift Winch pulls the Carrier up the Ramp and over the drilling floor to mouse hole so tubulars can be delivered to or removed from the drilling floor. The Carrier has a Lift Arm mounted on its underside, which travels inside the Catwalk as the Carrier is pulled up the Ramp. The Lift Arm enters a pocket, which causes the back end of the Carrier to lift up out of the Catwalk. This allows the Carrier to extend across the drilling floor to the mouse hole. The Carrier Lift Winch is operated from the Control Console or from the Wireless Control. The speed of the Carrier travel is computer controlled throughout its range so damage does not occur to the Carrier or Lift Arm during operation.

    Turn on the Wireless Control, see Figure 14. Make sure the E-Stop Button is up.

    Wait for the green light to start flashing and after the second beep, press the green Arm / Reset button on the right side to arm the unit. OK NO ERRORS should be displayed on the Operators screen. If errors exist on the display, correct the error(s) before attempting to run machine.

    Press the Motor Start button. The computer has been programmed with a Carrier Encoder Override control.

    Press the Motor Start button and the Arm / Reset button simultaneously. Then, while holding the buttons, operate the Carrier Lift control lever to un-spool cable on the drum.

    If it becomes necessary to unwind enough cable to cause the Stopped Cable Spoolout Limit error to appear the hydraulic pump will shut off. It will now be necessary to open the Control Console to turn the Pump Auto/Hand Selector Switch to the Hand position to restart the pump. The Carrier Encoder Override control must be used until this alarm can be reset. Be sure the pump switch is returned to the Auto position once this alarm has been cleared. The rig up procedure can now be continued.

    Ensure the Carrier is resting fully toward the hydraulic tank end of its travel before raising the Ramp. This will prevent Carrier track damage on the lower end of the Ramp during rig up.

    Ensure that cables do not bind or pinch while unfolding Ramp.

    The weight of the Ramp is between 13,000 to 15,000 Lbs (5,986 to 6,803

    Kgs)

    Use the rig tugger winches and a pull back line connected to the Lifting Point, see Figure 25, to raise the Ramp. Use the pull back line to prevent the Ramp from falling onto the Rig Floor when it rotates over center.

    NOTE Unwind approximately 5 to 6 feet of cable from the drum so the Ramp can be

    raised without the Carrier picking up and binding on the end of the Ramp.

    Ensure the speed setting is set at slow speed on the Wireless Control.

    Figure 25: Ramp Lifting Point

    After Ramp has been lifted past its balance point and is beginning to lower to rig floor watch the lower end of the ramp to ensure the Carrier wheels are not interfering with the track on the Ramp. Ensure the Carrier tracks (channels) do not bind on the ramp posts when entering.

    Once the Ramp is resting on the Rig Floor, pull back the Catwalk using the winch truck so that the lip of the ramp sets on the Ramp hanger with a 1/2 (1.27cm) gap between the lip and the Rig Floor. If resting directly on the rig floor, see Figure 26, keep 1/2 (1.27cm) gap between the sheave saver and the edge of the rig floor.

    Once the Ramp is in position, attach the safety chains to the chain mount on the Rig Floor. Pull the slack in the chain through the chain mount and slide the chain into the slot to secure it.

    Loading Tubulars to the Drilling Floor

    Always ensure Pipe Rack Hydraulic Legs are properly deployed

    before operating the equipment.

    NEVER leave tubulars on the catwalk when the carrier is in operation. All tubulars must be on the Pipe Racks during Carrier operation. Tubulars could roll under the Carrier or Lift Arm causing extensive damage to the equipment.

    Figure 36: Pipe Handler, Cross Section When unloading tubulars from pipe tubs or onto the stationary racks with a loader, make

    sure the tubulars are positioned close to the Ramp end of the Catwalk so when the time comes to load them onto the Carrier, they will clear the Skate properly (Range III pipe and casing typically).

    NEVER double stack tubulars on the Pipe Racks, this prevents loading

    tubulars into the Carrier using the Indexers.

    Set the Pipe Stopper Pin in the appropriate stopper hole so that the Indexer delivers one tubular at a time. The Indexer should catch more than half of the tubular while it is resting against the Stopper Pins.

    Load the Pipe Racks with tubulars. Maximum capacity of each rack in 5000 lbs. Raise the Pipe Racks so tubulars roll up against the Pipe Stopper Pins.

    Ensure the Skate is retracted behind the tubular to be loaded. Actuate the opposite side Safety Pins to prevent tubulars from rolling past the Carrier. Use the Indexer Outer Raise Control to lift one tubular at a time into the Carrier. Once

    the tubular starts rolling, release the lever to drop the Indexer. With practice, it can be anticipated how long to hold the Indexer up to cause the tubular to just roll onto the Carrier and drop into the groove.

    When the tubular is resting in the Carrier groove, use the Skate to push the tubular as far forward as possible without hitting the cable protector slots on the Ramp. This pushes the weight forward making it easier to lift the load.

    The maximum weight capacity of the Carrier is 10,000 lbs. Use the Carrier Lift Control Lever to raise the Carrier up to the drilling floor. The Safety

    Pins raise automatically as the Carrier lifts out of the Catwalk. The Carrier automatically accelerates and decelerates as it lifts. Run the Carrier only as far forward out over the Rig Floor as necessary. It will stop automatically at mouse hole.

    Use the Skate to push the tubular further off of the end of the Carrier into the reach of

    the elevators. Once the elevators have latched, the tubular can be picked up off of the Carrier.

    Depending on the weight of tubular, the Carrier can be left in place to help control the tubular as its pin end slides off of the Carrier or, the Carrier can be lowered slightly sooner to improve cycle time when tripping.

    DO NOT push tubulars up the Carrier as the elevators are lifting it,

    this will cause mechanical damage.

    NOTE The Indexers, Kickers, and Pipe Racks will not operate when the Carrier is lifted

    out of the Catwalk or when the Skate is in operation.

    NOTES There is a Safety Curtain Laser Eye on either side of the Catwalk that will shut

    down the device if the beam is broken while the Carrier is in motion. The Carrier Lift Winch will not operate if there is an object on the Catwalk blocking the Safety Curtain Laser Eye.

    Carrier Encoder Override. The computer has been programmed with a Carrier Encoder Override control sequence. Press Motor Start button and the Arm / Reset button simultaneously. While holding these buttons, operate the Carrier Lift control lever to wind or unwind cable on the drum.

    The Carrier Encoder Override should be used during rig up/down procedure, if the encoder requires re-zeroing, or during certain maintenance procedures.

    5-8 Revision April 2011

    Lowering Tubulars from the Drilling Floor Set up the Pipe Racks so the tubulars will roll down the Pipe Racks onto the stationary

    racks. Remove the Stopper Pins. Remove the Pipe Rack outboard pins if desired.

    Lift the Carrier up to the Rig Floor and extend it as far over the floor as required. For faster tripping with light pipe, position the Carrier closer to the edge of the Rig Floor. Usually a thread protector is spun on prior to setting the tubular onto the Carrier groove.

    Make sure the Skate is positioned back just behind where you anticipate releasing the tubular from the elevators.

    Push the tubular out and set it on the Carrier groove. Slowly start lowering the blocks. The bottom end of the tubular should slide down the groove as the blocks are lowered. If the tubular sticks, back the Carrier up slowly to increase the angle of the tubular until it begins to slide.

    Prior to releasing the tubular from the elevators, bring the Skate forward to support the tubular so it does not slide back uncontrolled and impact (collide with) the Skate. This could easily damage the Skate or Skate Winch and will seriously reduce the life of the Skate cable.

    Once the elevators have been released, retract the tubular just past the end of the Carrier. Keep the tubulars, especially heavy tubulars, as close to the front end of the Carrier as possible to reduce the load on the Carrier Lift Winch when lowering.

    Retract the Carrier down the Ramp to the Catwalk. Once the Lift Arm rollers have left the Pocket and the Carrier is rolling back on its rear wheels, use the Skate and gravity to slide the tubular back to position it over the Kickers. This can be done while the Carrier is traveling down.

    When the Carrier is fully retracted into the Catwalk, The Carrier Lift Winch will automatically stop and the Safety Pins will lower.

    If the tubular is properly positioned, retract the Skate back away from the tubular, and then actuate the appropriate Kickers to eject the tubular out of the Carrier groove. Raise the inner Indexers to roll the tubular onto the Pipe Racks.

    NEVER leave tubulars on the Catwalk when the Carrier is in

    operation. All tubulars must be on the Pipe Racks during Carrier operation. Tubulars could roll under the Carrier or Lift Arm causing

    extensive damage to the equipment.

    When Tripping Out ensure the Skate supports the Tubular before

    releasing the Tubular from the Elevators.

  • Section 5: Operating Procedure

    Revision April 2011 5-9

    DO NOT position Skate over the Kickers before actuating the Kickers to

    prevent mechanical damage to the Skate mechanism.

    If the tubular is not positioned correctly, you may need to lift the carrier back up the Ramp part way and use gravity and the Skate to position the tubular over the Kickers.

    As soon as the tubular is onto the Pipe Racks the Carrier can be lifted for the next tubular.

    NOTE The Indexers, Kickers, and Pipe Racks will not operate when the Carrier is lifted out

    of the Catwalk or when the Skate is in operation.

    Hydraulic Oil High quality hydraulic oil is essential for satisfactory performance and long hydraulic system component life. Oil having 150 to 330 SUS viscosity at 100F (38C) and viscosity index of 100 or greater will give good results under normal temperature conditions. The use of oil having a high viscosity index will minimize cold-start trouble and reduce the length of warm-up periods. A high viscosity index will minimize changes in viscosity with corresponding changes in temperature. Maximum cold weather start-up viscosity should not exceed 5000 SUS with a pour point at least 20F lower than the minimum ambient temperature. Under continuous operating conditions the temperature of the oil at any point in the system must not exceed 180F. 120-140F is generally considered optimum. Anti-wear type hydraulic oils are recommended. These oils are generally developed and evaluated on the basis of pump wear tests such as ASTM-D2882. These oils offer superior protection against pump and motor wear. They also provide good demulsibility as well as protection against rust.

    Skate Cable Maintenance Check Skate cable tension once per month and adjust if necessary. To check tension, move the skate to the rear of the Carrier, lift the Carrier up the ramp part way so that the under side of the Carrier can be inspected. Install the safety stop bar. Slowly run the Skate forwards while watching the cable. The cable will momentarily become slack as the cable wraps on the Skate Winch Drum move across the drum from one side to the other. At its lowest point, the cable should not hang more than 4 inches below the underside of the Carrier frame. Tighten the cable by removing the locking plate at the rear of the Carrier and then equally threading in the cable tensioner bolts. Do not over tighten the cable. Every month add a small amount of hydraulic oil to the Skate Cable while a second operator is moving the skate repeatedly to each end of its travel.

    Figure 62: Skate Cable Tensioner.

    Ensure all personnel are clear of any moving parts to prevent

    accidental injury or death.

    CARRIER WINCH MAINTENANCE Lubrication The following table gives the recommended viscosity in relation to ambient temperature. Other brand products may be acceptable, be certain that your lubricant supplier provides oil

    That is equivalent to those shown here. Note: cSt is the same as mm2/s. For special conditions consult Canrig for recommendations. The recommended working temperature of the sump should be between 50 and 70C (122 to 158F). The intermittent peak temperature of the sump should be no greater than 95C (203F). The winch is filled via the filler plug. Fill with gear oil until it reaches the oil level gage / port. Refer to manufacturers literature for more information.

    DO NOT OVERFILL as this may cause the winch to overheat. DO NOT work under the raised Carrier without the Safety

    Stop bar installed.

    Do not operate or perform any lubrication, maintenance or repair on this product, until you have read and understood the operation, lubrication, maintenance and repair information.

    Changing Oil

    Using the correct type and viscosity of lubricating oil is critical to

    the proper function of this winch. The sprag clutch is particularly sensitive to EP (extreme pressure) additives.

    Failure to use the correct type and viscosity of oil may cause

    failure of the winch to hold the load and result in property damage, personal injury or death.

    Procedure for Changing Oil

    1. Before changing oil, consider taking an oil sample for analysis. 2. Run the winch to warm up oil and to ensure particles are suspended in the oil. 3. Place an oil pan or bucket beneath the drain port to collect the oil. 4. To allow oil to drain from the winch, loosen and remove the plug. 5. Rotate drum to fill position. 6. Fill with the correct oil to the correct level. Correct oil level is indicated when the oil

    begins to run out of the plug at the 9-Oclock position. 7. Replace and tighten the drain plug. 8. Operate the winch for 30 seconds. 9. Stop the winch for 30 seconds then re-check for correct oil level. 10. Check that fittings and plugs are correctly tightened. 11. Dispose of used oil and clean up any spillage in an environmentally sound way.

    Hot oil and components can cause personal injury. Do not allow hot oil or components to contact skin.

    Winch Usage Category

    Mounting Bolts The recommended torque for the Winch mounting bolts is 600 ft. lbs., Figure 54. Tighten all winch base mounting bolts to recommended torque after the first one hundred (100) hours of operation, then every 1000 operating hours or six (6) months, whichever occurs first. Tighten all Winch Cable Clamp bolts to recommended torque after the first one hundred (100) hours of operation, then every 1000 operating hours or six (6) months, whichever occurs first, The recommended torque for the Winch Cable Clamp bolts is 110 ft. lbs., Figure 55.

    Figure 64: Carrier Lift Winch (Lantec) Drum Bearing Adjustment Outboard Bearing Group 405255 requires endplay adjustment. Check endplay every 1000 operating hours or six (6) months, whichever occurs first. Tighten the adjusting nut to remove all endplay in the bearings, then loosen the adjusting nut turn. This will give the required 0.020-0.030 bearing endplay. See Component Literature.
