API 579 Part 6 Pitting Assessments Using INSPECT
INSPECT performs level 1, 2 and 3 pitting assessments and generates detailed API 579 reports with one button click. Assessments can be performed for both localized and widespread pitting. In addition, pitting damage may be located internally, externally, or on both sides of the vessel. Interactions between pitted regions and local thin areas are automatically detected and addressed as well. Other highlights include:
Pitting flaws are displayed to scale on the INSPECT 3D model.
Images may be added 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.
Joint efficiency may be defined for each flaw’s location.
Calculations using ASME Section VIII Division 2 equations can be performed by activating Code Case 2695.
Supplemental load calculations are provided. INSPECT calculates supplemental loads automatically, with vessel geometry, vertical loads, lateral forces, wind and seismic loads taken into consideration. Supplemental loads may also be manually entered.
Tensile and compressive longitudinal stresses are considered for all applicable load cases. The allowable compressive stress is calculated using the methodology in API 579-1 Annex A.
