Abstract
An electrically-powered service rig utilizes an engine-driven generator to power a propulsion system, a drawworks system and a sandline system, all mounted on a single mobile platform. The rig utilizes lightweight permanent magnet motors to enable integration of the systems onto a single mobile platform which meets transport regulations. The rig's power plant is capable of powering other on-site equipment such as mud pump motors through use of umbilicals connected to the engine-driven generator.
