6. Once the elevators have been released, retract the tubular just past the end of the carrier. Keep the
tubulars, especially heavy ones, as close to the front end of the carrier as possible to reduce the load
on the carrier-lift winch when lowering.
7. 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.
8. When the carrier is fully retracted into the Catwalk, the carrier-lift winch will automatically stop and the
safety pins will lower.
9. When the tubular is properly positioned, retract the skate back away from the tubular and 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.
10. If the tubular is not positioned correctly, you may need to lift the carrier back up the ramp part way and
use the skate and gravity to position the tubular over the kickers.
11. As soon as the tubular is on the pipe racks, the carrier can be lifted for the next tubular.
HMI Screen Display
The Catwalk is operated from an HMI screen display (Figure 5-4, page 5-9) mounted on the control
console. During operation, the PLC continually monitors the various systems and indicates status or any
errors. To clear an error, press the RESET button on the control console or on the wireless terminal.
Following is a list of possible on-screen status and error messages, and what they indicate.
Caution
To prevent mechanical damage to the skate
mechanism, DO NOT position the skate over
the kickers before actuating the kickers.
NOTE
Indexers, kickers, and pipe racks will not
operate when the carrier is lifted out of the
Catwalk, or when the skate is in operation.
