Varco TDS-3Top Drive

Seller Description

Varco TDS-3 Top Drive includes main drive section and electric motor, without quill or pipe handler. This unit is Varco 500 ton Serial # TDS3A13Y234, rated at 37,000 ft-lbs max torque.  Weight 15,640 lbs. Was used for scientific coring operations on the drillship Joides Revolution until replacement with new technology top drive system costing millions of dollars. A pipe handler was never fitted for use in this coring application. In 2017 it was fully rebuilt and tested by top drive specialists Global Drilling Support in Houston, about $70,000 of work. It had a Cat 4 inspection (sandblast, NDT, and paint), all bearings, seals, O-rings, hydraulic hoses, and has been warehoused since then. The built-in pressure lubrication system was also rebuilt. At that time the GE 752 DC electric drilling motor was also rebuilt and tested by Global Tech Motors & Controls in Houston including new bearings. Motor is Model #5GE752AUT2, S/N #EE92010210, 1085 hp, 750 Volt DC, 1150amp, 965rpm.  Rebuilder said the motor had not been in use. We can manufacture and include a new API splined quill at extra cost with your choice of API threads. This top drive is uniquely built with a large 10″ nom bore splined hollow main shaft which allows a splined quill to be dropped in. Pipe handler is a separate system which is not included but can be located for approx. $30,000. The TDS-3 top drive was designed to be suspended from a 500 ton rotary swivel which is readily available in many brands.  A quill can be made with drill pipe connections desired, upper would be LH to match the rotary swivel.
