The new single-piece substructure is a slingshot-style unit with integrated hydraulics to provide the fewest number of connections ever required for full rig up. The API monogrammed substructure offers a 27-1/2” split master bushing with a maximum table opening of 44”, which easily accommodates large diameter tools and complex bottom hole assemblies.
Epiroc introduces DH350, the first of a new line of oil and gas drilling rigs
The powerful Epiroc-designed 1,200 HP diesel-hydraulic power unit provides unparalleled distribution of hydraulic power for all drilling functions, while enabling an unprecedented reduction in fuel consumption to easily get through the day. The stand-alone HPU minimizes cycle time between wells by eliminating the necessity of high voltage power from ancillary prime movers and remains an integral component atop the DH350 substructure when walking the rig between wellheads.
The crownless telescopic mast featuring 54” Nylatron sheaves provides 350,000 lb. of pullback, 50,000 lb. of pulldown force through the robust tip-out hydraulic top drive. The twin spur gear powerhead offers variable speed electric over hydraulic control with a maximum 30,000 ft-lb of rotary torque, and the ability to handle single joints of Range III drill collars up to 8” inches in diameter. The top drive delivers substantial improvements to operator safety and offering the highest quality pipe handling when coupled with the integrated iron roughneck and remote operated catwalk.
"The DH350 combines the mobility of carrier drive rigs with the power density of conventional skidded systems to produce one of the most agile and capable drilling rigs in the marketplace today"
