Pressure Vessel Design, Registration & Verification


At Sherwood Design & Engineering, we offer the service of pressure vessel design. In conjunction with our 3D modelling and design drafting capabilities, we can produce a detailed pressure vessel drawings, ready for manufacture. As part of the package, we will supply the calculation set as well as drawings, and can seek independent 3rd party verification of our designs for registration with the relevant authority.

Our qualified engineers can design pressure vessels for you to the Australian Standard AS 1210 and can sign off as designer for Design Registration with the relevant authorities. We also work in conjunction with a number of very capable fabrication companies should you require the full design and construction of a vessel. To complete the process, we can also recommend a pressure vessel engineering inspector for final sign of for Item Registration so that the vessel can be put into service.


We offer the service of pressure vessel design verification to a large domestic and international client base. If a vessel is determined to be within a specific range of Hazard Levels, then registration of the design with the relevant statutory authorities is mandatory prior to the vessel being put into service. For the design to be registered, it must be checked and signed off by an independent 3rd party verifier. We offer this service.

  • We can verify your pressure vessel design to the International Standard to which it was designed.
  • We can submit for pressure vessel registration on your behalf to any relevant authority in NSW and around Australia.
  • We can assist in the steps required for getting your pressure vessel put into service.
  • The verification service we offer is undertaken by experienced and fully qualified engineers.

The pressure vessel verifiers at Sherwood Design & Engineering have experience in pressure vessel certification in Australia, with verification to Australian Standards AS1210 and AS1228, as well as US codes ASME VIII Division 1, ASME I, and European Standards. Our verifiers are also fully qualified professional engineers, members of the Institution of Engineers Australia and Registered Professional Engineers of Queensland (RPEQ). With the qualifications and experience of our verifiers, we can sign off and submit for pressure vessel design registration in any state of Australia.


Our verifiers can advise you of the registration process and have experience in dealing with every registration body throughout Australia (WorkCover, WorkSafe, etc). To determine if registration of your pressure vessel or boiler design is required, the first step in the process is to determine the Hazard Level to AS4343. Based on this Hazard Level, we can advise if registration of the pressure vessel design with the relevant authority is required.

Once the design has been registered and a registration number has been issued for your vessel by the relevant authority, each vessel made to that design will likely require item registration. For pressure vessel item registration, a pressure vessel inspector will need to inspect the vessel to allow signing off. We work with a number of pressure vessel inspectors who we can recommend for assistance in the final stage of the process of putting a pressure vessel into service.


It’s mandatory if your vessel is hazard level A, B, C or D, and you can be liable for a fine if you don’t. The process of pressure vessel design verification and registration involves comparison of the design to the design requirements of the nominated international standard, for the stated design and operating conditions. This process is to assure that the design is compliant and that the equipment has sufficient structural integrity for in-service conditions by meeting the minimum requirements of the relevant standard. Design verification is concerned with the equipment safety rather than equipment functionality.
