We offer the service of pressure vessel design, and in conjunction with our 3D modelling and design drafting capabilities, can produce detailed fabrication drawings of the design, ready for manufacture. As part of the design 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 pressure vessel fabrication companies should you require the full design and construction of a vessel. To complete the process, we can also recommend a pressure vessel 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 design registration on your behalf to any relevant authority in 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.

Pressure vessel design verifiers at Sherwood Design & Engineering have experience in verification to Australian Standards AS1210 and AS1228, as well as US codes ASME VIII Division 1, ASME I, and European Standards.

Verifiers at Sherwood Design & Engineering are fully qualified professional engineers, members of the Institution of Engineers Australia and Registered Professional Engineers of Queensland (RPEQ). This company is a Quality Assured company and combined with the qualifications and experience of our verifiers, allows us to 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 design of the pressure vessel with the relevant authority is required.

Should verification and registration of the design be required, we can act as 3rd party verifiers, and should the design be found to comply with the nominated Standard, sign off for Design Registration. 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 Item Registration, a Pressure Vessel Inspector will need to inspect the vessel to allow signing off for Item Registration with the relevant authority. 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.

The process of pressure vessel design verification 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 not equipment functionality. Inquire now regarding our services.
