The Level 3 fitness-for-service assessment demonstrated the DIB tower with the local metal loss damage from CUI was fit-for-service, enabling the plant tocontinue to operate for the next two years until the scheduled turnaround.I, Mary Harney, Minister for Enterprise, Trade and Employment, in exercise of the powers conferred on me by The stress/strain distributions at the LTAs for current and future conditions were analysed and compared with the global and local plastic collapse criteria available from the API579 standard.

A series of different LTA models reflecting progressive corrosion damages were developed by taking into account not only the current damage level, but also a maximum possible corrosion rate as predicted by statistical method employing extreme value calculation. A 3D finite element model of the DIB tower including the local thin area (LTA) was created to determine the realistic stress distribution at the LTA considering, vacuum, design condition as well as operating condition. Therefore, a Level 3 assessment involving 3D finite element modeling was required to determine whether the Deisobutanizer tower with the localised corrosion damage was fit-for-service until the next scheduled shutdown. A Level 2 API579 local metal loss assessment failed to satisfy the fitness-for-service criteria.

Abstract Corrosion Under Insulation (CUI) was found adjacent to the T-Type vacuum stiffening rings of the Deisobutanizer (DIB) tower.
