Dual Fuel Cat 3512’s Chosen For Land Drilling Modules

Posted on June 10, 2014

Caterpillar Oil & Gas announced that the Cat 3512C land electric-drive drilling modules with dynamic gas blending (DGB) have been selected to power Citadel Drilling Ltd’s, new fleet of AC Triple drilling rigs which are expected to total 12 to 14 rigs over the course of the next five to six years.

Three Cat 3512C modules each with rated power of 1045 eKW (1476 bhp) at 1200 rpm, will be used to power each land drilling rig. The first three Cat DGB units have been delivered and tested and are slated to be field operational by the end of June 2014 on Citadel’s first rig. Cat dealer Finning Canada led the Caterpillar efforts on the sale and will continue to deliver support and service to Citadel.

The dynamic gas blending kit automatically adjusts to changes in incoming fuel quality and pressure allowing engines to run on a variety of fuels, from associated gas to vaporized LNG, with no loss of performance integrity, Cat said.

Cat said the DGB kit also maintains diesel performance levels with up to 70 percent replacement of diesel with gas, accepts up to 55 percent inerts and can be applied to existing engines with EPA certification. No customer input or gas analysis is needed during operation, and no recalibration is required when the equipment is moved or the gas supply changes.
