Varco drilling systems. 1998 г. 64 стр.
Varco engineering has made use of the recent advancements in AC
technology by designing the
TDS-11SA to be powered by two AC drilling motors (either 400 or 350 hp each, depending on
the configuration). These 800-hp and 700-hp systems produce 32,500 and 37,500 ft lb of
drilling torque respectively. They can provide 47,000 and 55,000 ft lb of make-up/break-out
torque respectively.
The TDS-11SA is compact enough to operate safely in a standard 142' mast while providing 500
tons of hoisting capacity. Its highly portable design allows for rig-up and rig-down in just a few
hours. It easily integrates into existing rigs at minimal installation cost and minimal rig
modification.
