National Oilwell Varco’s Russia/CIS manufacturing facility located in Kostroma, Russia is nearing the completion of its first extreme cold weather drilling rig, the Kostroma train rig. The Kostroma Train Rig was designed by NOV rig engineers in Russia, the USA, and Canada with significant experience designing drilling rigs for the harsh winter drilling conditions and logistical challenges of the Former Soviet Union.
With optimized rig up and accelerated rig move capabilities, the 1500 horsepower, (320 metric ton hook load capacity) drilling rig is designed for pad drilling in Russia, Central Asia and the Caspian Sea Region at temperatures ranging from +45 to -45° C. The Kostroma train rig also incorporates an innovative rail system that allows the rig to move from well to well without rigging down, much like a train.
The new NOV Kostroma Train Rig features the following equipment:
1.) TDS-11SA Top Drive (800 hp/596 kW),
2.) ST-80C² Iron Roughneck (makeup torque 60,000 ft-lb/81.3 kNm),
3.) Spherical and Double Ram Blowout Preventers (5000 psi/rated to 340 atm),
4.) DSGD-320 Drawworks with a hoisting capacity of 320 metric tons with 10 lines,
5.) 2 x FD-1600 Triplex Mud Pumps (1600 hp/1190 kW)
6.) Amphion Automated Drilling Control System
The Kostroma Train Rig has the ability to operate using diesel generators or 6.3 kV highline power. The rig also can be rigged up and rigged down using only 40 ton mobile cranes, which is significant in Russia/CIS as it doesn’t need the heavy 60, 80 and 100 ton mobile cranes which are difficult to find in remote drilling locations.
The Kostroma Train Rig is currently completing Rig-Up and Commissioning and will be available for demonstration in late Q1 2018 at NOV’s manufacturing facility in Kostroma, Russia!
