PIPE HANDLING SYSTEMS
Herrenknecht Vertical integrates various automated pipe handling systems into rig concepts to enable hands-off operations, eliminate hazardous working places and increase operational safety. On conventional rigs, automation of pipe handling and racking processes can be applied as an upgrade.
For conventional vertical pipe racks at the mast, Herrenknecht Vertical has developed a modernization package. It replaces the derrick man at fingerboard level by a two-component pipe handling system that allows for automated hands-off tripping operations. The lower pipe feeder at rig floor level bears the full load of the handled tubulars. The pipe guide at the mechanized fingerboard moves synchronously with the pipe feeder. The system can handle drill pipes in triples, and drill collar, with a maximum weight of 6 metric tons (6.6 short tons) and maximum diameter of 9 inches.
The special design does not require a reinforcement of the derrick structure, as loads are directly transmitted into the rig floor and substructure. This is the major benefit compared with other fingerboard automation systems. The stand-alone component modernization package comes with its own containerized power supply and control system with anti-collision and interlock concept.
