AUMA has 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.
AUMA’s SIMA control system was successfully integrated into the tank farm’s existing SCADA system. It uses the open and standardised 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 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 for optimised process control.”
AUMA’s local representative in Indonesia, PTC, supplied the complete solution including system integration as a turnkey package to Pertamina. Experts from PTC not only mounted the actuators but also laid all the power and fieldbus cables and installed all electrical connections. They also provided parameterisation and commissioning of the actuators, and hassle-free integration into the SCADA system.
Pertamina is the state-owned company responsible for crude oil and gas production and processing in Indonesia. AUMA has a proven track record of more than 20 years supplying electric valve actuation solutions to Pertamina.
