The Evolution of Top Drive Drilling

In 1981 the first top drive was introduced; providing the drilling community with clear advantages to traditional Kelly drilling, such as, increased safety, well control and performance.

20 years later, National Oilwell Varco (NOV), the engineering pioneer behind the top drive revolution, introduced the TDS 8.

Thanks to its unmatched reliability and global service and support network, the TDS 8 is the drilling industry’s most prolific 750 ton top drive on the market.

The TDS 8 Top Drive has the “AC Advantage” with its use of a 1150 hp AC drilling motor and is a multi-purpose tool ideal for use on semi-submersibles and jack-up as well as large land applications.
