Safe State Engineering helps operators design, verify and manage safety instrumented functions across the IEC 61511 lifecycle, backed by SIFGuard, our purpose-built lifecycle software.
From the first hazard study to the tenth proof test, we help you get safety functions right and prove they stay that way.
HAZOP, LOPA and SIL determination.
SRS development for each SIF.
Architecture, PFD and constraints.
Testing and functional safety assessment.
Keeping the SIF fit for purpose.
Many safety tools only handle process SIFs. We also cover the machine-state logic that drives safety functions across mining and materials handling.
Concentrators, crushers, conveyors and ship loaders, where process limits and machine state both trigger protective action.
Onshore and offshore facilities where safety cases and performance standards depend on demonstrable SIF integrity.
Major hazard facilities where the SIS is central to the safety case and to regulator confidence.
A connected, version-controlled record for every safety instrumented function. The documents regulators and assessors expect are generated from the data, not the other way round.
Safe State Engineering was founded by functional safety engineers with years on WA mining, port and oil & gas projects. We kept seeing the same problem: the engineering was sound, but the evidence lived in disconnected documents and spreadsheets.
We work to IEC 61511 and IEC 61508, and to the Australian regulatory frameworks our clients operate under. SIFGuard is the tool we wanted on every one of those projects.
