Recertification Of API 653

  • API 653 Pressure Vessel inspectors need to apply for recertification every three (3) years.
  • You may apply for recertification 90 days prior to the certification expiration date, and for a 90-day grace period after. Late fees apply after the expiration date.
  • If an application is not submitted by the end of the 90-day grace period, the certification will expire. A new application and fees must be submitted, and you will need to pass a full examination in order to be recertified.

    Circumstances such as heavy work schedule or work in other countries or remote areas do not relieve the inspector/examiner of the responsibility to file a timely renewal application.
  • API 653 inspectors need to demonstrate that a minimum of 20% of time over the most recent three-year certification period was spent performing or supervising pressure vessel inspection activities as described in the API 653 inspection code.

    Inspectors who have not been actively engaged in pressure vessel inspection practices will be required to take the full examination. API 653 Recertification Effectively sheet
