API 579 Fitness for Service Assessments
Ensure integrity, avoid costly repairs, and minimise downtime with our specialist API 579 Fitness for Service Assessments.
If you’ve recently discovered that your tank doesn’t meet the thickness criteria required by EEMUA 159 or API 653, our team of specialists at BES Group can help.
If a tank shell does not meet required thickness criteria as per EEMUA 159 (or API 653) standard calculations due to localised corrosion, further assessment on the locally corroded area can be conducted to potentially assure integrity, possibly avoiding repairs or reducing capacity/inspection intervals.
API 579 Fitness for Service Assessments are suitable for tank shells that exhibit localised corrosion that exceeds the allowable limits defined in EEMUA 159 or API 653 standards. However, it is important to note that these assessments are not applicable for tanks with widespread or severe corrosion or for tanks that have already undergone significant repairs or modifications.
Don’t let localised corrosion compromise the integrity of your tank shell. An API 579 Fitness for Service Assessment can provide valuable insights into the condition of your tank, allowing you to make informed decisions about its continued use and maintenance. By investing in this assessment, you can protect your investment, ensure operational continuity, and potentially extend the service life of your tank shell.
A strategic approach to API 159 assessments
We employ a standardised API 579 assessment process that ensures a rigorous and consistent evaluation of your tank shell's condition. This process encompasses the following key steps:
-
Preliminary inspection: We conduct a thorough inspection to locate and assess the extent and severity of localised corrosion on the tank shell.
-
Detailed UT Grid: If localised corrosion is identified, we perform a detailed UT grid to map the corrosion with precise accuracy.
-
UT data analysis: We analyse the UT data to create a detailed corrosion map, highlighting areas of significant thinning and providing a comprehensive overview of the corrosion’s impact.
-
Assessment calculations: Utilising the UT data and API 579 guidelines, we perform calculations to evaluate the remaining structural integrity of the tank shell.
-
Fitness for Service Evaluation: We conduct a comprehensive fitness for service evaluation, determining whether the tank shell can continue to operate safely with the existing corrosion or whether repairs or other measures are required.

Extend tank service life
By confirming the integrity of the localised corrosion area, you can potentially avoid costly repairs or replacements, extending the lifespan of your tank shell and reducing your overall maintenance costs.
Avoid capacity reductions and inspection interval changes
If the assessment demonstrates that the tank shell can still safely operate, you can avoid capacity reductions or more frequent inspections, ensuring uninterrupted operations and maintaining efficiency.
Prevent unexpected outages
By identifying and addressing localised corrosion issues proactively, you can minimise the risk of unexpected outages caused by structural failures, ensuring the continued reliability of your tank.
