NOV Stand Transfer Vehicle
What it does
The Stand Transfer Vehicle works at the fingerboard. A carriage rides rails on the diving board and guides the top of a stand between well center and the fingers. The head captures the stand instead of clamping it, so the lean of a stand — pin in the setback, box at well center — does not side-load the machine.
Which rig it fits
It fits the mast it was laid out for. The onshore guide’s upper-guide-arm figures are a Zone 1 classification, 15 gallons per minute at 2,500 psi, 120 volts AC, 90 psi air, and 2,500 pounds for the guide arm alone. Tubular range is 3½-inch drill pipe to 10-inch collars. Slew is 90 degrees in 3.2 seconds. The system includes the fingerboard and the carriage. A different mast means a different machine.
How to tell it apart
A PipeCat or a Canrig catwalk moves pipe from the ground to the floor. The STV never does that. It handles stands that are already stood back. A mousehole hoist is a third, smaller machine at the mousehole. Buying an STV does not replace either of those.
What to check before you buy
Confirm the mast type, the stand length, and that the carriage, rails, and head are all in the sale. An arm without the fingerboard rails it was built for will not transfer stands.
Sellers list what they have, so this exact model is not always up. Pipe Handling & Rig Floor Tools is where that kind of equipment is listed.
