API 510: Pressure Vessel Inspector

RINA's (previously Edif ERA) online and residential training course helps delegates prepare for the API 510: Certified Vessel Inspector examinations.

Topics covered by the RINA API 510 training course include vessel certification requirements and the types and definitions of vessel maintenance inspections; remaining life and inspection intervals are also touched upon. Delegates learn to recognise vessel corrosion and deterioration and how to work with vessel relief devices. They are instructed in maintenance inspection safety practices and how to generate thorough inspection records and reports. Code calculation for in-service degraded pressure vessels (including repairs and re-rating), vessel weld joint efficiencies and weld joint categories are also reviewed. Delegates are taught how to conduct internal and external pressure calculations and they are made aware of impact test requirements as well as the pressure testing requirements which are necessary after repairs.

RINA courses are run in the weeks immediately prior to each exam window so that delegates can benefit from concentrated practice and support in preparation for the exam. Please note, RINA  does not book API examinations for the delegates: they must do this directly with API. 

To become an API certified inspector, delegates are required to meet the criteria set by API and pass the formal examinations at an authorised API examination centre.

For those wishing to undertake the API 510 examinations specific to vessel inspectors, RINA  offers a stringent training programme with two stages:

  • Preliminary distance learning modules
  • A full-time residential classroom course reviewing the topics covered in an API 510 exam and offering revision sessions and mock examinations.

Delegates must undergo an assessment procedure to attend this course.

What is API?

The American Petroleum Institute (API) offers a certification programme for individual in-service inspectors handling the in-service inspection of pressure vessels, pipework and storage tanks. API also manages an expansive catalogue of API “codes” which standardise practice. The programme is a legal requirement for many US states, however, the extension of US ownership to include international facilities and onshore plants along with the lack of a similarly broad scope of recognised standards in other countries has resulted in the wide adoption of API practice within international plant industries. Thus, many UK regulatory authorities also use these codes to assess evidence of inspector competence. The API certification programme is broken down into a series of API schemes, known as Individual Certification Programmes (ICPs), of which API 510 is one.
