AUMA has supplied a turnkey valve automation solution to Indonesian national oil and gas company Pertamina. 12 SAEx multi-turn electric actuators with ACExC integral controls plus a SIMA control system support the first phase of an expansion project at the TBBM Manggis LPG tank farm, Bali.
AUMA’s SIMA control system is integrated into the tank farm’s existing SCADA system. It uses standardised Modbus RTU communication between the valve actuators and the higher-level SCADA system. The actuators connect to the SIMA in a ring topology with integrated redundancy. At SCADA level, the AUMA system with its Modbus RTU communications operates in parallel to an existing system with older actuators using a proprietary communications protocol.
“This project shows that a stepwise upgrade to AUMA in existing plants is possible at any time and without any problems,” says Stefan Kolbe, sales director Southeast Asia at AUMA. “The customer particularly appreciates the flexibility and future-proofness of the investment thanks to the open fieldbus standards. They also see benefits in the short response times of the AUMA solution, which allow optimised process control.”
AUMA supplied a complete turnkey package to Pertamina, including installation and commissioning of the actuators and hassle-free integration into the SCADA system
