RINA's online and residential training course helps delegates prepare for the API 653: Certified Storage Tank Inspector examinations.

Topics covered by the RINA API 653 training course include:

  • Code calculations and inspection intervals for new and degraded storage tanks in relation to corrosion rates and allowances
  • Remaining service life and inspection intervals and pitting assessment
  • Thickness calculations for tank shells and floors
  • Working pressure and temperature requirement
  • Tank settlement and distortion evaluation
  • Hydraulic testing and impact test requirements and exemptions

The course also reviews tank repair, looking at patches and lap welds, weld heat treatment requirements and the general rules for welding in an API and ASME context.

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 delegate: 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 653 examinations specific to vessel inspectors, RINA offers a stringent training programme with two stages:

  • Preliminary distance learning training modules
  • A full time, residential classroom course reviewing the topics covered in an API 653 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. 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 653 is one.

**API 653 normally involves a 3-month online self-study element followed by an 8-day classroom course. Where necessary during Covid, we are running the API 653 course fully online, with the 3 months self-study followed by a 5-day live webinar course.
