According to the information that I have seen, the options are an RPE (from Canada or the US) or someone who is:
"An Engineer experienced in pressure vessel design who meets all required qualifications to perform engineering work and any supplemental requirements stipulated by the user. The Engineer shall identify the location under which he has received the authority to perform engineering work stipulated by the user in the Design Specification.", although ti should be noted that:
"The Engineer certifying the Manufacturer’s Design Report shall comply with the requirements of the location to practice engineering where that Report is prepared unless the jurisdiction where the vessel will be installed has different certification requirements."
This sounds like a good opportunity to discuss whether or not Div 2 vessels (or even pressure vessels in general) should be certified by a registered professional engineer. Thoughts?
One thing that I will take from this definition is that if you are in Canada or the US, you will have to be an RPE if you want to certify a MDR (on the basis of the second statement saying that engineer shall comply with the requirements of the location to practice engineering where that report is prepared). So in Canada or the US, there is legislation dictating who can practice engineering - only RPEs.
The common practice for vessel (Div 1) manufacturers in the US is to perform designs using staff personnel, few of which are PEs. The advent of slick ASME pressure vessel design programs now allows non-PEs to perform far more sophistcated engineering analysis of non-pressure loadings than ever before. Regardless what the PE laws state, they have hardly ever been applied to the design of Div 1 vessels.
