What types of registrations are required in Australia for pressure equipment?
There are two types of registration:
(1) design registration, which is a one-off process for every unique design.
(2) item (or plant) registration, which is the registration of actual plant as required by the regulations.

What types of pressure equipment require design registration in Australia?
Pressure equipment including heat exchangers, finned tube air coolers, boilers, autoclaves, air receivers, condensers, tanks, pressure vessels within air conditioning units and other pressurised systems,... categorised as hazard level A, B, C and D according to the criteria identified in AS4343 Pressure equipment - Hazard levels are subject to design registration in Australia.

What are the requirements of regulations for design registration?
Work Health and Safety (WHS) Regulations in Australia require that designs of pressure equipment categorised as hazard level A, B, C or D according to the criteria in Section 2.1 of AS 4343 Pressure equipment - Hazard levels must be registered with a WHS Regulator in a state or territory.
As part of the registration process, a pressure vessel design must be checked and verified by an independent design verifying body that the design complies with the original design code and/or Australian standard AS1210 Pressure vessels.
Designer, manufacturer, importer, owner or supplier can apply for a design registration number.

When design-registered equipment is altered in such a way that it constitutes a major change in its design, the design registration becomes invalid and a new design registration number must be obtained from WHS Regulator for the equipment. The person designing the alteration should carry out a risk assessment on the altered vessel and consider all hazards. For pressure equipment that has been altered, a verification statement is also required stating that the alterations comply with a published standard.

The design registration number obtained is used for item registration.

Does pressure piping require design registration?
No.

Do small volume vessels require design registration?
Vessels greater than 0.05L in volume may require design registration depending on vessel contents (pressurising fluid) and design conditions.

Do non-metallic pressure vessel designs require registration?
Yes. Pressure vessels made of plastics, fibre-reinforced plastics, glass or other non-metallic materials with a hazard rating A, B, C and D in accordance with Australian Standard AS 4343 also require design registration in Australia.

What is the procedure of design registration?
Briefly, the following documents, as applicable, are prepared and submitted to WHS Regulator for approval and registration:
- an application form signed by applicant, designer and design verifier
- a design verification statement to the satisfaction of the WHS Regulator stating that the design of pressure vessel complies with the design code or Australian standards (AS1210, AS4343) and engineering principles used in the design
- a third party certified representational drawing of the pressure equipment
- determination of Hazard Level to AS4343
- AS/NZS ISO 9001 Certificate of design verifier
- a registration fee

Can a design be registered in two different states?
No.

Who can apply for a plant design registration?
A manufacturer, designer, importer, supplier or owner of a plant can apply for a plant design registration.

What are the documents required for design verification?
Where design verification is required for a pressure vessel, a heat exchanger or an air cooler; at least the following documents shall be provided for design review:
(1) representational drawing/s showing design conditions, contents of pressure equipment, dimensions, materials of construction, weld details and other details considered by the designer to be essential for proper verification
(2) mechanical design calculations

The mechanical design calculations shall be verified for compliance with the appropriate Australian Standards (AS1200, AS1210, AS4343, AS4458, AS3992, AS4037) or other published standards (ASME VIII, API 660, API661, API662, PD/BS5500, EN13445, DIN/AD 2000 and GB150,..) considered appropriate by the regulatory authority, and any additional purchaser’s specifications.

Is ASME sufficient to meet the code requirements for design registration?
Yes, ASME Boiler and Pressure Vessel Code Section VIII is acceptable.
In addition to ASME other published standards are also acceptable in most states/territories.

Is a registration number issued by a state valid for Australia wide use?
Yes.  States and territories accept a design registration number issued by another Australian State or Territory. As a general condition, the design verification statement must be completed and signed by a competent person who does not have any involvement in the design being verified and the design verifying body has an accredited quality system that meets the requirements of AS NZS ISO 9001.

What is the duration of design registration?
A plant design registration is granted for an unlimited duration. However, if the design of a registered plant is altered,  the altered design must be re-registered.

What is the lead time to obtain a design registration number?
Authorities usually issue a design registration number in 4-8 weeks depending on their workload at the time of application.

Is there a way to expedite the registration process?
No. Pacific Engineering can only accelerate design verification process.

Do all designs require verification?
Yes, all designs including altered designs require design verification. The application documentation for registration must include a statement by a design verifier that the design is in accordance with the technical standard and/or engineering principles used in the design.

What is the extent of design verification?
The following aspects of the design shall be verified:
- materials of construction of pressure parts
- thickness and adequacy of all pressure parts
- supports where applicable
- manufacture and testing requirements
- specifications for flanges, valves and fittings
- any other aspects of the design which are essential for verification

Can Pacific Engineering register a design?
Yes. Pacific Engineering can help you deal with the documentations required for certification and registration of pressure vessels in any state/territory in Australia. We can prepare and submit the application documents for registration on your behalf. Following application, the Authority will issue a design registration certificate (and a design registration number) for each pressure equipment.
According to Australian Standards AS1210, the design registration number must be hard stamped on equipment or etched on a nameplate that is permanently attached to the vessel.

Can Pacific Engineering register designs in Western Australia?
Yes, we can register pressure vessel designs in Western Australia as well as in other states and territories in Australia. We have already registered numerous vessels/heat exchangers in New South Wales, Queensland, South Australia, Victoria, Western Australia, Tasmania and Northern Territory.

What are Major Hazard Facilities (MHFs)?
Major hazard facilities are workplaces that store, handle or process large quantities of hazardous material. Major hazard facilities typically include chemical plants, oil refineries, gas processing plants, LPG and LNG facilities and other manufacturing and transport depots.

How does MHF affect AS4343 hazard level calculations?
According to AS4343 Table 1, a factor of 3 is used in hazard level calculations of pressure equipment installed in a major hazard facility as defined in the National Occupational Health and Safety Commission (NOHSC) and relevant state legislation.

What are major alterations to pressure equipment?
Examples of major alterations include;
- An increase in design pressure or temperature of pressure equipment
- A decrease in MDMT
- The addition of new nozzles or openings which require redesign.
- Dimensional change of pressure equipment which affects stress calculations
- An increase in heating surface in a heat exchanger
- The addition of a pressurised jacket to pressure equipment
- Change of material of a pressure retaining part in a pressure vessel
Where a major alteration is made to Hazard Level A, B, C, D pressure equipment, the alteration is treated as a new design and the altered design requires re-registration.

Do we need to stamp design registration number on vessel or a nameplate?
Per Australian codes, design registration number provided by WHS Regulator must be stamped on each vessel or etched on a nameplate that is permanently attached to the vessel.

Certification and registration of imported pressure equipment
Verification of the design of imported equipment is carried out in accordance with AS3920 by a certified design verifying body such as Pacific Enginering Pty Ltd.

Where disputes between the manufacturer and the design verifying body or the need for interpretations arise, the dispute or interpretation shall be referred to the WHS Regulator or to Standards Australia.

Certification by Pacific Engineering
After a design has been reviewed, subject to its compliance with the code requirements, a design verification certificate will be issued. Original copy of the certificate will be submitted to the WHS Regulator for registration and a copy of the certificate will be forwarded to the applicant for reference.

Confidentiality
The details of the design in our possession are disclosed only to the regulatory authority, certifying body, or a person authorized by the owner of the design.
