INSPECT – API 579 Fitness-For-Service Simplified

INSPECT performs the calculations and assessments needed by Engineers engaged in process plant inspection and maintenance activities.  It creates detailed Fitness-For-Service (FFS) reports for pressure vessels, heat exchangers, piping, and above ground storage tanks.  INSPECT Fitness-For-Service Software reduces regulatory compliance risk by creating ASME design reports for your undocumented pressure vessels.  It also organizes and adds context to your inspection data by showing CML’s and API 579 flaws on its 3D equipment models.  And for 2021, INSPECT adds support for FFS flaw assessments on Division 2 vessels.

Depending on your needs, INSPECT’s API 579 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’s integration with Shopfloor, our weld procedure software, simplifies repair weld tracking as well.

INSPECT is a Fitness-For-Service extension of our market leading COMPRESS pressure vessel software.  It includes all available COMPRESS functionality and shares the same user interface and file format.  This makes upgrading from COMPRESS to INSPECT simple and efficient.  Users new to Codeware products benefit from an easy to learn user interface that minimizes training time and reduces implementation costs.

INSPECT Featured API 579 FFS Software Capabilities

INSPECT:  Comprehensive FFS + Mechanical Integrity Software

INSPECT's API 579 FFS assessments cover a wide range of equipment and flaw types


Taking equipment out of service is expensive but leaving damaged equipment in service can be risky.  INSPECT’s FFS assessments assist Engineers in determining if repair or replacement is really necessary.  A wide range of flaws are addressed including general and local metal loss, pitting corrosion, grooves, dents, gouges, cracks, creep, HIC, out-of-roundness, laminations, and fire damage.  Complete Part 3 brittle fracture checks automatically support INSPECT flaw assessments.  INSPECT’s Minimum Safe Operating Temperature curves can quickly screen process equipment that may be exposed to auto-refrigeration. INSPECT’s data logger integration can quickly turn thickness survey readings into FFS results and help ensure turn arounds stay on schedule.  INSPECT produces detailed API 579 remaining life reports that let you verify the calculations performed and provide RAGAGEP support for your recommendations.

INSPECT Includes API 653 Storage Tank Evaluations, Inspection Data Management and Reports

ASME VIII, API 510, API 570, and API 653

INSPECT’s mechanical integrity capabilities include a flexible inspection data management system that lets you specify the CML data to track.  Rigorous tmin, remaining life, and inspection interval calculations are built-in. All API 510 and API 570 Code results are supported by full ASME VIII (both Division 1 and Division 2), ASME B31.3, ASME B31.4, and TEMA calculations and reports.  Old ASME VIII-1 Codes, dating back to 1950, are supported.  INSPECT helps safely extend equipment life and inspection intervals by implementing the most economical Code allowable stresses and weld joint efficiencies permitted by the NBIC / API 510. API 653 storage tank assessments include consideration of shell out-of-plane and edge settlements, floor bulges, and patch plates.

Unlike competing FFS software, INSPECT shows the governing CML on the equipment 3D model

Pressure Vessel Re-Rating With INSPECT

  • INSPECT quickly performs ASME compliant pressure vessel re-rating calculations and includes support for ASME Codes dating back to 1950.

  • INSPECT accurately determines what equipment re-rating does to equipment remaining life and inspection schedules.

  • Unlike other mechanical integrity systems, INSPECT produces extensive audit trail reports that document all calculations performed.

  • Minimum Safe Operating Temperature (MSOT) Curves

  • Part 10 Creep Assessments

  • Part 11 Fire Damage Assessments

  • Vessels constructed to old ASME Codes (1950-present) are supported
