AC/VFD Drive Systems: BAC 1500

Designed to work with 2-1600 HP mud pumps and 3-1087kw diesel/gen sets, the BAC 1500 HP control system is an AC VFD control system with a maximum hook load of 3500KN. It consists of the drilling control system, mud pump control system, instrumentation, MCC and power supply system, TV monitor and talkback system and management computer system. Like the BAC 750, the BAC 1500 can operate the process control function independently, and then work with other systems to provide total integrated control.
