Structured Approach for Floating Roof Integrity Assessment and Preventive Measures

Different tanks have different roof types, and each roof requires specific design considerations to insure safe operation and extended service life. Also, each type needs continuous integrity assessments along with corrective maintenance. However, some operational upsets lead to unaccepted damages, that if left unassessed, and not repaired will lead to catastrophic failures. The paper will shed lights on the common failures of the floating roof, and their common causes during operation of the tank, or even during incorrect practices for cleaning. Then the paper will discuss integrity assessment approaches to assess damages, and the proper methodology for repair. Finally, the paper will share guidelines on the preventive measures that operators need to consider to avoid damages and ensure safe floating roof operation.
