After doing pressure vessel design for ten years, can one actually serve as an approver?

1. The technical supervisor shall be the person in charge of design work within the unit. This individual must hold the title of senior engineer and possess professional knowledge related to pressure vessels. They should be familiar with relevant laws, regulations, rules, safety technical specifications, and standards pertaining to pressure vessels, and be capable of making correct decisions regarding major technical issues. 2. Approver: (1) Engaged in work within this profession, possessing relatively comprehensive professional technical knowledge related to design ； (2) Be able to properly apply the laws, regulations, rules, safety technical specifications, and relevant standards related to pressure vessels, and be able to organize and guide designers at all levels in their implementation ； (3) Familiar with relevant design work and the development of related technologies both domestically and internationally; possesses comprehensive analysis and judgment capabilities, as well as the ability to handle key technical issues ； (4) Having more than 3 years of experience in relevant design review and corresponding project experience ； (5) Hold the title of Senior Engineer. 3. Reviewer: (1) Able to earnestly implement laws, regulations, rules, safety technical specifications, and relevant standards related to pressure vessels; possesses comprehensive professional technical knowledge in design to ensure design quality ； (2) Able to guide designers and reviewers in properly complying with laws, regulations, rules, safety technical specifications, and relevant standards related to pressure vessels, as well as to resolve technical issues in the design process ； (3) Have at least 5 years of relevant experience in design review and verification, along with corresponding achievements ； (4) Hold an engineer title. 4. Verifier (1) Capable of applying laws, regulations, rules, safety technical specifications, and relevant standards pertaining to pressure vessels to guide designers in their work, thereby ensuring the quality of design documents ； (2) Possess relevant design expertise ； (3) Ability to use computers for design ； (4) Have at least 3 years of relevant design experience and corresponding achievements ； (5) Hold the title of Assistant Engineer. 5. Designer (1) Possesses relevant design expertise ； (2) Able to implement laws, regulations, rules, safety technical specifications, and relevant standards related to pressure vessels ； (3) Able to complete design work independently under the guidance of reviewers, and capable of using a computer for design ； (4) Possess the title of Assistant Engineer and have more than 1 year of practical design experience. Following the path outlined above, those who have been engaged in pressure vessel design for 10 years are not eligible for approval; the required time is 1 year of practical experience + 3 years of design work + 5 years of verification work + 3 years of auditing work = 12 years in total. In other words, it takes at least 12 years after graduating from university to become an approver.
Your algorithm is incorrect. 3 years of design includes the actual implementation year; 5 years of design verification includes the 3 years of design.
The internship period doesn’t count, right? Work experience is calculated starting from the date indicated on the graduation certificate
Wrong; a company may have 4 designers. According to your logic, even after 12 years only 1 of them will be the approver, while the other 3 will remain designers. What’s worse, after 11 years an approver will be hired from outside, but those 4 designers will still be designers. Don’t doubt it.
The issue of the duration is worth discussing; it would be best to have an authoritative explanation. Why is it stipulated that design review experience should be stated instead of simply reviewing experience?
Internships during student days are not counted, but formal internships after graduation at companies are counted
Your algorithm is correct; it is indeed 12 years
The time periods for design, verification, and review aren’t clearly demarcated. For instance, in the third year of working as a designer, one might be tasked with verifying some relatively simple equipment； In the third year of the verification role, some auditing tasks might have been undertaken, and so on. Furthermore, the reviewers and approvers of pressure vessels are collectively referred to as approval personnel, and they must pass a professional assessment conducted by those responsible for approving pressure vessel designs (there is no separate professional assessment requirement specified for approvers in the management system) ； As for who among the approval personnel should be designated as the approver, this is primarily determined by the design unit’s own needs, and they may submit a report for recordation at their discretion. Therefore, under favorable circumstances, quite a number of people manage to obtain the qualification as a pressure vessel design approver after working for about 10 years, especially in some small and medium-sized design institutes or companies that primarily focus on manufacturing but also have design capabilities.
According to the original \"Rules for Licensing the Design of Pressure Vessels and Pressure Pipelines,\" the reviewers were required to have more than 3 years of experience in relevant design verification; this 3-year period certainly did not include time spent on actual design work. In this light, the 5 years specified in TSG07-2019 refer to 5 years of experience in verification work, meaning that at least 11 years are required to become an approver (with even one year counting toward this total).
