SYSTEM FOR SUPPLYING POWER FROM THE MAIN POWERHOUSE TO A DRILL FLOOR POWERHOUSE

摘要

A system for supplying power for drilling operations has a main powerhouse and a drill floor powerhouse in which the drill floor powerhouse is movable in relation to the main powerhouse. The main powerhouse has an generator/generator, a mud pump, and a mud pump drive thereat. The mud pump drive is supplied with power from the engine/generator. The drill floor powerhouse as an energy storage system connected or interconnected to an output line from the engine/generator such that power from the engine/generator is directed to the energy storage system. The drill floor powerhouse has a load connected to the energy storage system such that power from the energy storage system is directly transferred to the load and such that power from the engine/generator is isolated from the load.
