What is FFS • A quantitative engineering analysis to determine if an equipment with existing flaw can still be fit for continued service

When to use FFS

Life stage

Equipment condition

Acceptance criteria

Example Codes

Construction

Brand new

Workmanship

ASME VIII, ASME B31.3

In service

Used, corroded, deteriorated

Fitness-for-Service

API 510, API 570 API 579

Conclusion: • Never use FFS as justification to accept poor workmanship during fabrication / construction!

Objectives of course

At the end of this week, participants will be able to do the following: • Perform ballpark & rough FFS on simple problems • Know when & where to get help when things get complicated • Know what to do to learn more about FFS

What is API 579 A code for assessing in-service structures found with defects • Brittle fracture • General thinning • Local thinning • Pitting • Cracking • Creep • Mechanical damage • Fire damage

Is API 579 the only one out there? Various FFS codes available worldwide • API 579 • BEG R6 • BEG R5 (for creep assessment) • DNV RPF-101 • BS 7910

And there are several others….

Learning approach

When you buy a new gadget, do you…. •Read the instruction manual first and play with the gadget later? •Or play with the gadget immediately and read the instruction manual later (if ever)?

Learning approach 1st day & 2nd day • Thinning – localized and general

3rd day & 4th day • Cracking

5th day • Formal steps & procedures

Let’s get started
