INSPECT API 579-1 FFS Overview
INSPECT’s API 579-1 FFS can assess individual components, complete vessels, or model entire process systems. INSPECT performs rigorous tmin calculations that can extend vessel remaining life and inspection intervals. INSPECT also organizes and adds context to your inspection data by showing CML’s and API 579-1 flaws on its 3D equipment models. And for 2021, INSPECT adds support for FFS flaw assessments on Division 2 vessels.
Below is the complete list of API 579-1 parts available in INSPECT today.
Part 3 – Brittle Fracture Assessments
Includes both level 1 and level 2 assessments for carbon and low alloy steels
Assessments performed at the specified Critical Exposure Temperature (CET) instead of the MDMT as used in UCS-66
Run multiple Part 3 assessments for each flaw and produces a Minimum Allowable Temperature (MAT) curve
Part 6 – Pitting Assessments
Pitting flaws are displayed to scale on the INSPECT 3D model
Add images to the Level 1 pitting report to satisfy the Part 6 requirement for a scaled photo or rubbing of the surface of the damage
Pitting measurements may be entered manually or copied and pasted from a spreadsheet
Part 9 – Crack-Like Flaw Assessments
Quickly determines which crack-like flaws can be safely left in service and which require more investigation
Report shows how crack length compares with the allowed length based on the screening curves of API 579-1
Automatically performs a Part 3 brittle fracture analysis
Part 10 – Creep Damage Assessments
Quickly determines which crack-like flaws can be safely left in service and which require more investigation
Report shows how crack length compares with the allowed length based on the screening curves of API 579-1
Automatically performs a Part 3 brittle fracture analysis
Part 11 – Fire Damage Assessments
Organize relevant observations and document conclusions in a consistent series of data entries and reports
Provision is made for recording visual evidence, fuel, and ignition source
Heat exposure zones (HEZ) may be assigned to entire pressure vessels or individual vessel components
Convenient fire damage summary report lists the components included along with applicable Pass/Fail conclusions
