Capability
SIS, ESD, fire & gas and BMS engineeringto IEC 61511.
ATG's principal held the plant-wide sole SIS engineer position on a twenty-seven-controller ProSafe-RS system for seven years. That is the standard we bring to every safety scope — from a single burner management system to a plant-wide safety system digitalisation for Saudi Aramco.
Detect early. Act correctly. Prove it.
What ATG delivers
Scope we takeunder our own contract.
- Safety requirement specification, cause and effect matrices and SIL-rated architecture (1oo2, 2oo3) selection.
- ESD, fire and gas, burner management and HIPPS application programming with independent verification.
- Fire and gas detection layout, detector selection, voting logic, alarm and mimic panels and suppression interfaces.
- Safety system data integration and dashboarding — proof-test tracking, bypass and demand logging — without touching the safety logic.
- Integrated FAT with the DCS, SAT, cause and effect validation and site commissioning.
- Proof-test procedures, functional safety assessment support and management of change after handover.

Frequently asked
Questions buyers askbefore the shortlist.
Which safety PLC platforms has ATG commissioned?
HIMA (including a SIL 4 system for Shell Nigeria), Triconex, Yokogawa ProSafe and ProSafe-RS, Honeywell Safety Manager and Emerson DeltaV SIS. We are currently executing the HIMA scope of a plant-wide safety system digitalisation at Saudi Aramco Khurais.
Do you deliver the HAZOP, LOPA and SIL studies as well?
Yes — see our functional safety studies page. Independent facilitation is delivered separately from the implementation so the assessment stays independent.
Can you work on a live plant?
Yes. Online modification, bypass-managed testing and hot cutover on operating assets are the norm for our safety-system work.
Functional Safety Studies — HAZOP, LOPA, SIL, FSA
Independent HAZOP facilitation, LOPA, SIL determination and verification, and FSA to IEC 61511.
