SYSTEM AND METHOD FOR THE EXTERNAL GENERATION OF ELECTRICAL POWER FOR MOBILE WELL DRILLING EQUIPMENT.

Abstract

An external power generation system for a mobile well rig is disclosed, comprising a chassis that supports: a frequency converter configured to control an electric motor arranged to receive power from the converter and convert it into mechanical energy; a transmission; a shaft mechanically connecting the motor and the transmission; and a drive system comprising a first gearbox, an input shaft mechanically connecting the transmission to the first gearbox, and an output shaft with a proximal end coupled to the first gearbox and a distal end extending beyond the chassis and connectable to the output shaft of a mobile well rig, thereby transferring mechanical power to the output shaft of the rig and from there to the winch of the rig for raising and lowering equipment suspended from the rig's mast.
