Structural Integrity Assessment of a Fire Damaged Process Column
Structural integrity assessment of existing plant is often required following the discovery of excessive corrosion or other damage. In one such project, undertaken for the operator of a large oil refinery located in the south of England, FCL carried out work to establish the significance of two major deviations from design shape, taking the form of a “bulge” and an “indentation” in the upper shell of a process column, which were caused by a pyrophoric scale fire.
The findings of the work, which were underwritten by a series of supporting design code calculations and input from metallurgists, who were able to provide mechanical property data for the fire damaged material, confirmed the integrity of the column for continued operation and thereby avoided the need for costly repair work which would have required the column to be taken out of service and would have resulted in a consequent adverse impact on refinery throughput.
