Udemy – API 579 Fitness-for-Service (FFS) Engineering

Every inspection report eventually lands on your desk with the same question: run, repair, rerate or replace? When a vessel, pipe or storage tank shows metal loss, a crack, a blister or fire damage, a simple minimum-thickness check is no longer enough. You need a defensible engineering answer — and that answer comes from API 579-1 / ASME FFS-1. This course teaches you how to do Fitness-for-Service assessment properly, from first principles through to worked examples you can apply on real equipment, today.

What you will be able to do after this course:

• Explain the FFS framework — Assessment Levels 1, 2 and 3 — and select the right level for any finding
• Calculate the Remaining Strength Factor for a corroded shell using a real thickness profile
• Assess general and local metal loss (Parts 4 & 5), pitting corrosion (Part 6), blisters, HIC and SOHIC (Part 7), and laminations
• Plot and interpret the Failure Assessment Diagram (FAD) for a crack-like flaw
• Characterise and recategorise flaws correctly under Part 9
• Assess creep damage, fire damage, dents and gouges (Parts 10, 11 & 12)
• Determine MAWP and calculate remaining life
• Produce technically defensible FFS documentation and an Engineering Critical Assessment (ECA)
