Automated Racking-Board Pipe-Handling System Eliminates Hazards of Tripping Operations,Reduces Rig Personnel,and Creates Consistent Tripping Speeds in Line with Best Rig Crew Performance
Tripping of drill pipe is known to be one of the most dangerous and physically demanding jobs on the rig and involves a derrickman and rig floor hands that are often subject to various injuries.Now this hazardous operation can be automated,which moves personnel out of harm’s way and simultaneously creates attractive and very consistent tripping results. In this paper we will discuss field experiences while introducing such a system into an active onshore drilling operation in Canada.The unit is lightweight and fit for first installations,or it can serve as a retrofit-capable package.The Iron Derrickman S3 comes with a custom racking board that pins directly in the place of a conventional racking board.Complete with a standalone control system and power unit, it makes for a quick and easy addition to any rig.It immediately increases safety by actually removing the Derrickman from his exposed position and simultaneously making a floor hand redundant.The reduced incident exposure realized from removing the need for a Derrickman to climb up the mast and manhandle a nearly 9000lb stand of pipe with the supporting floor hands on the rig floor that control the bottom of the stand(in the red zone)and drive it around the floor each time a stand of pipe is needed,is tremendous.As you can see in the IADC Industry LTI’s numbers from 2013,the incidents on the floor, in the racking board and involving Derrickman make up the lion’s share of all LTI’s on the rig annually. The Iron Derrickman S3 is an engineered solution that will help eliminate these hazards. This novel robotic system is suitable for onshore and for offshore jack-up rigs.It was retrofitted into a Nabors Rig in northern Canada with little or no modification to the rig.The nonintrusive system increased productivity on the rig floor and uses proven industrial robotics to achieve smooth,safe,and efficient transfer of stands to and from well center to programmed coordinates in the racking board. The sequential automation allows full operator control at any stage of the process and provides more consistent and efficient tripping than manual handling.The pre-programmed SemiAutomated system allows for continues,repetitive and predictable performance that empowered operators to easily perform the task of moving pipe around on the rig between well center and the finger board from a safe distance. This technology also allowed for a short training cycle for rig crews.
