Capabilities

Key Advantages

01

Walking System

Full pad-walking capability with hydraulic catwalk — walk 45' between wellheads without rigging down. Ideal for multi-well pad drilling programs in tight spacing.

02

Dual-Fuel DGB Kits

CAT DGB (Dual Gas Burn) kits on all three low-hour 3512C engines enable natural gas substitution, cutting fuel costs significantly on gas-producing pads or where pipeline gas is available.

03

Upgrade Path to 1500HP

Engineered drawing plans available for upgrade to 1500HP/750KLB hook load — a clear path to higher performance requirements without a full rig replacement.

04

Winterization Package

Winterization with boiler included, along with Totco electronic drilling recorder, Mathey wireline unit, manrider, and meeting/change house combo with A/C.
