Frequently asked questions — Oil & Gas

Does Authomathika hold certification for work in classified (hazardous) areas?

Yes. Authomathika has teams trained and certified for work in classified areas per ABNT NBR IEC 60079 standards. Engineering strictly follows zoning, area classification and Ex (explosion-proof) equipment specification requirements. We also comply with NR-20 and NR-33.

Do you install safety instrumented systems (SIS)?

Authomathika has experience in critical process automation with high-reliability and redundancy systems. We work with all major automation platforms (Rockwell, Siemens, Yokogawa, Emerson, ABB) that support SIS/SIL architectures for the oil and gas sector.
