Functional safety · Perth, Western Australia

When the process goes wrong, it has to reach a safe state. Every time.

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.

What we do

Engineering and evidence across the whole safety lifecycle

From the first hazard study to the tenth proof test, we help you get safety functions right and prove they stay that way.

Analysis
Hazard & risk

HAZOP, LOPA and SIL determination.

Specification
Safety requirements

SRS development for each SIF.

Design
SIL verification

Architecture, PFD and constraints.

Validation
FAT, SAT & FSA

Testing and functional safety assessment.

Operation
Proof test & MoC

Keeping the SIF fit for purpose.

Where we work

Process plant and fixed plant, on the same site

Many safety tools only handle process SIFs. We also cover the machine-state logic that drives safety functions across mining and materials handling.

01

Mining & minerals processing

Concentrators, crushers, conveyors and ship loaders, where process limits and machine state both trigger protective action.

02

Oil, gas & energy

Onshore and offshore facilities where safety cases and performance standards depend on demonstrable SIF integrity.

03

Chemicals & major hazards

Major hazard facilities where the SIS is central to the safety case and to regulator confidence.

Our software

SIFGuard™

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.

  • One record per SIF, from hazard to proof test
  • Traceability across HAZOP, LOPA, SRS and verification
  • Generated outputs: SRS, LOPA and SIF summaries
  • Audit-ready version history and approvals

About

Built by practitioners, in Western Australia

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.
