\r\n
\r\nItem: \u2022Coke drums fabricated from 1CrMo steel
\r\n
\r\nObjective: \u2022To determine the probability of failure as a function of operating cycles, for input to a risk-based plant management programme
\r\n\u2022To obtain the optimum balance between drum life and process performance
\r\n
\r\nApproach: \u2022Review history, install strain gauges and thermocouples
\r\n\u2022Analysis of operating data
\r\n\u2022 Probabilistic assessment of fatigue crack initiation and growth
\r\n\u2022 Modification of operating cycle in the light of the observed behaviour
\r\n\u2022Refined assessment based on revised operation<\/p>\r\n
Benefits:
\r\n\u2022Risk-based quantification of drum life
\r\n\u2022Improved life and availability by understanding and controlling the effects of operational parameters
\r\n\u2022Optimised operation, allowing improved performance whilst minimising damage-initiating events
