Pertamina expands liquid gas tank farm

Auma supplied a turnkey valve automation solution to Indonesian oil and gas company Pertamina. The scope of delivery includes 12 SAEx multi-turn electric actuators with ACExC integral controls plus a Sima control system. The delivery is part of the first phase of an expansion project at the TBBM Manggis LPG tank farm on the island of Bali. The Sima control system was integrated into the tank farm’s existing Scada system. It uses the Modbus RTU protocol to communicate with 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 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,” says Stefan Kolbe, Sales Director Southeast Asia at Auma.
