PDVSA, Venezuela’s state-owned oil and gas company, selected MCL Control S.A. as the system integrator (SI) and HIMA as the safety systems provider to implement turbomachinery control at the Planta de Compression Tiajuana 3 on Lake Maracaibo.

The new system will enable the gas plant to benefit from a single platform for turbo compressor critical control.

Fast response times for surge and fuel control applications and easy integration with the GALBA SCADA were important to PDVSA. The company required integrated alarms, diagnostics and events, using standard communication protocols.

The GALBA SCADA is a system developed by PDVSA in order to advance in the independence and control of industrial process supervision technologies.

The HIMA turbomachinery solution, based on three HIMax SIL 3-rated safety systems used in the A and B compressor chains and refrigeration areas, meets IEC 61511 and the latest API turbomachinery protection standards. The system will end up programmed using SILworX software and serve more than 1150 I/O. Communication will occur via OPC AE, Modbus TCP master and slave, and Send&Receive TCP.

“Years of positive experiences with HIMA’s safety solutions and MCL Control automation engineering and services reinforced our confidence in their abilities to implement this new turbomachinery solution,” said Automation Gas Plant Project Team, Eng. Enrique Davis and Msc. Gerardo Queipo. “With the strategy considered by PDVSA the objective is to benefit more at the technology level: Technology independence, guarantee of maintaining the investment associated with the life cycle of the product and guarantee of technology transfer.”
