API 579-1 / ASME FFS-1
Fitness-for-service assessment of in-service equipment
API 579 / ASME FFS-1 is the fitness-for-service standard for in-service damage. Ask Deckhand to assess a corroded line or vessel from inspection readings and get a remaining-strength verdict.
What you can ask it to do
- Run a Level 1 / Level 2 general and local metal-loss assessment from wall-thickness readings against the design pressure.
- Estimate remaining strength and the maximum allowable working pressure.
- State the assumptions and where a Level 3 (detailed) assessment would be needed.

Questions
What is fitness-for-service?
A quantitative check of whether equipment with damage — corrosion, cracks, dents — is still fit to operate. API 579-1/ASME FFS-1 gives the assessment levels and acceptance criteria.
What can Deckhand assess?
General and local metal loss at Levels 1 and 2 from wall-thickness readings against the design pressure, returning the remaining strength and the allowable pressure, with the assumptions traced.
