Pressure vessel design
Design and code verification of vessels, columns and receivers to AS 1210 and ASME VIII.
Describe your projectWhat it covers
Pressure vessel design covers the mechanical design and code verification of vessels, columns, separators and receivers that hold pressure. The work runs from setting the design conditions and choosing a code, through wall thickness and nozzle calculations, flange and bolted-joint design, support and lifting-lug design, and the weld and inspection requirements that follow. A design engineer produces the calculation report, the general arrangement and detail drawings, and the manufacturing data report that lets a fabricator build and a regulator register the item.
When you need it
You need a pressure vessel design engineer when you are building new pressure equipment, modifying or re-rating an existing item, or registering a vessel as a regulated plant item. Higher hazard vessels must have their design verified and registered, so a documented design from a competent engineer is not optional, it is the basis for registration.
Standards, codes and tools
Commonly used tools: PV Elite, Compress, Ansys.
What to look for
Look for an engineer who works to the code your vessel will be registered under and who can produce a design verification statement, not just a model. Ask whether they hold RPEQ if the vessel will operate in Queensland, whether they have designed at the hazard level and pressure class you need, and whether they can cover the registration paperwork. A good design engineer also flags fatigue, creep or external pressure early, before they become a fabrication problem.

Common questions
Does my pressure vessel design need to be registered?
Higher hazard vessels under AS 4343 must have their design registered with the state regulator before they are built or operated. The registration relies on a design verification by a competent engineer, which is what a pressure vessel design engagement produces.
What is the difference between AS 1210 and ASME VIII?
Both are pressure vessel codes that set design rules and allowable stresses. AS 1210 is the Australian standard and is referenced directly by Australian registration. ASME VIII is the American code, widely used for imported or export equipment. An Australian engineer confirms which code your vessel must be registered under before designing to it.
Can the same engineer design and verify the vessel?
Design and independent design verification are separate roles for higher hazard vessels. The design engineer produces the calculations and drawings, and a separate competent person verifies them for registration. A firm can often provide both through different engineers.
