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

摘要

A system (100) for supplying power for drilling operations has a main powerhouse (102) and a drill floor powerhouse (104) in which the drill floor powerhouse is movable in relation to the main powerhouse. The main powerhouse (102) has a engine/generator (108, 110, 112), a mud pump (140), and a mud pump drive (138). The mud pump drive is supplied with power from the engine/generator. The drill floor powerhouse (104) has an energy storage system (152) 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 (104) 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.
