Fixed Equipment On-Stream Inspection Training

  • Online (Microsoft Teams)
  • +971 562069465
  • info@velosiaims.com
Course Overview

  • This course focuses on the principles and application of on-stream inspection for fixed equipment operating under pressure and temperature, in accordance with API 510, API 570, and API 653 requirements. It is thoroughly structured and explains when on-stream inspection is permitted, its limitations, and the inspector’s responsibilities while equipment remains in service. Participants learn to identify active damage mechanisms such as corrosion, erosion, CUI, and cracking using API RP 575 guidance.

    The course covers common inspection tools and techniques, including visual inspection, ultrasonic thickness measurement, and leak detection, as well as their limitations in operation. Emphasis is placed on recognizing early warning signs that may require increased monitoring, escalation, or shutdown. Practical case examples demonstrate how inspection findings are evaluated, documented, and translated into integrity and risk-based decisions. It equips inspectors and engineers with the skills needed to assess equipment condition and support sound operational integrity decisions safely.

Learning Objectives

  • By the end of this course, participants should be able to:

    • Understand the purpose and limits of on-stream inspection
    • Apply API 510, 570, and 653 requirements during operation
    • Identify active damage mechanisms using API RP 575
    • Select proper on-stream inspection techniques
    • Recognize warning signs requiring shutdown or escalation
    • Document findings and make sound integrity recommendations
Mode of Delivery

  • Training will be conducted via Microsoft Team Meeting. Meeting invites will be shared one day before the first day of training. 

    Face-to-face training is available as per request.
