What we do
- Independent Design Verification (IDV) to AS 1210 and nominated standards
- Hazard Level Assessment to AS 4343 (HL A–E)
- Design Registration lodgement with the relevant regulator
- Item Registration coordination (where required)
Standards & Codes
- AS 3920 – Pressure Equipment-Conformity assessment
- AS/NZS 1200 – Pressure Equipment
- AS 1210 – Pressure Vessel Design Code
- AS 4343 – Hazard Levels
Why choose PL Engineering
- Chartered Mechanical Engineer (MIEAust CPEng APEC Engineer IntPE , NER, RPEQ, RPEV) with ~20 years’ experience.
- National coverage: VIC, NSW, QLD, SA, TAS, WA & Comcare
- Regulator‑ready documentation & faster approvals
How it works
1) Kick‑off & Inputs
P&IDs, drawings, loads, materials, code edition, NDE/PWHT, relief basis.
2) Hazard Level (AS 4343)
Fluid/inventory/pressure/temperature → HL A–E (A–D typically register).
3) Independent Verification
Re‑checks for thickness, nozzles, flanges, supports, MDMT, buckling, relief.
4) Registration Pack
Verification report, declaration, calculations, drawings, relief device data.
Regulator coverage
- VIC: WorkSafe Victoria – Design verification declaration & registration
- NSW: SafeWork NSW – Design & item registration
- QLD: WorkSafe QLD – Plant design registration
- SA: SafeWork SA – Pressure vessel design application
- TAS: WorkSafe Tasmania – PRF1 (design) & PRF4 (item)
- WA: DMIRS / WorkSafe WA – Item registration
- Comcare: Commonwealth – Plant design & item registration
- National standards: AS 1210, AS 4343, AS/NZS 1200, AS 3788
Tip: WHS jurisdictions generally require both design registration (before manufacture/supply) and item registration (before use). Victoria’s framework differs for item registration—check the regulator page.

- Clear timelines and single point of contact
- Commissioning handover packs aligned to AS 3788
FAQs
Which vessels must be design‑registered?
Any pressure equipment (not piping) with AS 4343 hazard level A–D. HL-E is typically exempt from design registration but still subject to general plant safety duties.
Do we need item registration as well?
In WHS jurisdictions (NSW/QLD/SA/TAS/WA/Comcare): Yes—before use. In Victoria, the framework is different; confirm obligations with WorkSafe VIC guidance for plant.
How is hazard level decided?
Per AS 4343, using fluid, inventory, pressure, temperature and consequence criteria—yielding HL A (highest) to E (lowest). Registration usually applies to A–D.
