New rig designs: A quiet compact rig ///
KCA Deutag’s new T-208 rig is built for Europe’s demanding environmental standards. The modular rig uses a new, low-emission engine, the Caterpillar series 3512, which reduces NOx to less than 2,000 mg/m3, CO to less than 350 mg/m3 and particulates to less than 50 mg/m3. Fuel economy is good at 330 l/hr at 100% operating speed and 356 l/hr at 110% operating speed. Perhaps even more important for the crews is the rig’s sound insulation, which reduces mechanical noise from the generators, drawworks and other major equipment to 80 dbA at 1 meter.
KCA Deutag has produced modular rigs in the past with its first rig, T-43, going to work in the mid-1980s and the T-2000 entering the fleet in the late 1990s. While the T-43 had a modest 700 hp and the T-2000 rated 2,000 hp, the T-208 has a 1,150 hp rating for drilling to 5,000 m with 5-in. drill pipe.
