FAQ

Frequently asked questions.

  • Design Registration: Covers the engineering design of the equipment, including drawings, calculations, materials, and codes. A single design registration can apply to multiple identical vessels. This step is typically handled by the fabricator or importer.

  • Plant Registration: Applies to the individual piece of equipment and must be completed before commissioning on site. This responsibility usually lies with the owner or operator.

Any pressure equipment (excluding piping) classified as hazard levels A, B, C, or D under AS 4343 requires design registration before it can be installed or used.

Pressure equipment categorized as hazard levels A, B, or C must undergo plant registration before being commissioned. Hazard level D requires design registration only, and level E does not require registration.

A design verifier must:

  • Hold the competence, qualifications, and experience necessary to design or verify pressure equipment.

  • Be independent of the original designer, with no involvement in producing the design.

At GWE, verifications are performed by Chartered Professional Engineers – Pressure Equipment Verifiers, accredited under AS 3920 to deliver conformity assessments in line with WHS regulations.

The verifier is responsible for:

  • Reviewing the design against the nominated standard.
  • Documenting the verification process and results.
  • Issuing a Design Verification Statement confirming compliance with technical standards and sound engineering practice
No. Independence is mandatory. While the fabricator, importer, or owner can apply for design registration, the verifier must remain separate.
No. Design registration is applied for in a single jurisdiction, usually where the equipment will be installed. Once approved, the registration is recognised across all states and territories.
MHFs include sites such as oil refineries, chemical processing plants, and bulk fuel or chemical storage facilities, where large volumes of hazardous substances are handled. Regulators maintain public registers showing facility names, locations, licence terms, and conditions.
No. An ASME U-Stamp demonstrates compliance with ASME fabrication rules but does not replace the requirement for independent design verification under Australian WHS law.
