Rig floor equipment: Newly designed power slips
December 2004 Supplement Rig Floor Equipment Newly designed power slip
Newly designed power slipsNational Oilwell’s Rotary Round Power Slips improve drilling and tripping operations with simple, lightweight, compact, mechanical hydraulic slips. The slips can be operated anywhere on the drill floor via electro-hydraulic remote control, or manually by foot pedal and manual hydraulics. Two hydraulic cylinders operate the slip via a 1/4-in. hydraulic line. Required hydraulic pressure is 500 psi and 3 gpm.
The new slips will handle pipe ranges from 2-3/8-in. to 7-in. An adapter bracket pins into the customer-provided slips for easy installation. Mounting pins in the base of the new slips keep the mechanism attached to the rotary table during operations. The new slips increase safety by moving personnel away from the well center during drilling and pipe connection operations. In addition, the unique round design does not extend beyond the rotary table, thereby reducing trip hazards in the event of an accidental rotary table rotation. Crew fatigue is minimized by reducing time and energy required for manual slip operations. Used in conjunction with National’s new Iron Roughneck, the new Power Slips have greatly improved operational efficiencies in drilling operations and increased drill crew safety. |
