AC/VFD Drive Systems: BAC 6000

Designed specifically for the 12,000 meter well, the BAC 6000 Integrated Drilling Control System is an AC VFD system with a maximum hook load of 9000 KN. This redundant system is based on computer control, a digital vector VFD control program, and net technology, while the drawworks is controlled by a high-precision, load-balanced four-motor drive.
