STAND TRANSFER VEHICLE (STV)
1. Land Vertical Pipe Handling Guide Arm
2. Transfers stands of drill pipe/collar in/out of fingerboard, hands off to elevators.
SPECIFICATIONS
3 ½” to 10” Drill Pipe and Drill Collars Intuitive electric remote operator control with dual CCTV feedback Manipulates / guides tubulars between fingerboard and elevator Lightweight design easily transports in and out of mast Maintenance platform with direct hydraulic controls Manual racking possible
STV – WHY?
IADC 2009
US Land Rigs
23% of recordable incidents involved
derrickmen
IADC 2010
US Land Rigs
18% of recordable incidents involved
derrickmen
Tripping in & out of the hole is the leading cause
of lost-time and recordable incidents, 23%
and 19% respectively. (2010)
Recordable incidents involving derrickmen2009 I 6%2010 I 7.5%
Offshore has lower incident rates due to utilizing more mechanized pipe handling equipment
IADC Offshore Safety Statistics
VALUE TO OPERATION
Increase Safety Brings the second most experienced hand down to rig floor Rig floor becomes less hazardous Derrickman works side-by-side with the Driller and accelerates his learning
process to become the driller Increase Rig Performance
Crew Fatigue: STV does not tire over the work shift Maintains or improves tripping speed
Increase the marketability of the rig STV proves to Operators/Clients that the Contractor is serious about safety

• Diving Board Clamped to Fingerboard Support Structure
• “Rotates” if contacted by travelling equipment
• “Resettable” Shear Pins• Prevents Collateral Damage
Feedback
• 1.5M+ feet tripped• “Promotes safety amongst the crew!”• “Very intuitive, Really does Not Slow
Down the Tripping Process!”• “Would suggest one for every rig”• “Better Crew Interaction!”• “The Rocket rig with the STV has set
several records right out of the box. It has set the area record for fastest spud to TD. Also, the derrick-man has learned more from being in the drillers cabin operating the STV, over the last 3 weeks, about drilling and wellbore dynamics than he has learned over the rest of his career in the oilfield”.
