Industry leading tank floor settlement surveys

The integrity of storage tanks is paramount in the industrial and commercial sectors, as they hold a variety of hazardous and valuable substances. However, over time, tanks can experience settlements, which can lead to structural defects and potentially catastrophic failures. At BES Group, we’ll help you safeguard your operations and protect the environment with our comprehensive tank settlement, differential settlement, and tank floor surveys to thoroughly assess the condition of your tanks and identify any potential issues.

Our tank settlement surveys employ cutting-edge laser level technology to precisely measure and record settlement levels in designated locations as per EEMUA guidelines. This advanced method ensures accurate and reliable data, providing a clear picture of the tank’s overall integrity.

We meticulously monitor edge settlement, which occurs when the tank shell settles sharply around the periphery, causing deformation of the bottom plate near the shell-to-bottom junction. This condition can significantly compromise the structural integrity of the tank, making it vulnerable to ruptures and leaks.

Our qualified EEMUA Tank Assessors apply EEMUA 159 calculations, the widely accepted industry standard for tank integrity assessments, to determine if the recorded settlement levels fall within acceptable limits. This rigorous evaluation provides a comprehensive assessment of the tank’s structural stability.

To ensure the effectiveness of our surveys, we require specific information regarding the tank’s type and diameter to tailor our methodologies accordingly. Additionally, the tank interior should be clean and accessible to facilitate accurate measurements.

We strongly recommend conducting a comprehensive EEMUA 159 tank inspection alongside our settlement survey. This holistic approach provides a comprehensive evaluation of the tank’s condition, including its structural integrity, corrosion, and overall condition.

Our team of highly experienced and qualified inspectors provides you with the most comprehensive tank settlement, differential settlement, and tank floor surveys possible. We are committed to ensuring the safety and integrity of your storage tanks, protecting your operations and safeguarding the environment.

Contact BES Group today to schedule a tank settlement, differential settlement, and tank floor survey and take the necessary steps to maintain the structural integrity of your storage tanks. Together, we can prevent potential disasters and ensure the safety of your operations.

Hear what our customers have to say

We care about the journey we take our customers on, but it’s not our word you should be taking, see what our customers think of the service we provided!

The BES inspectors are way more technically competent and diligent compared to other providers. I previously used Allianz, and BES definitely stands out due to their strong technical competence and strong back office support.

The industry requires competence to be demonstrated, typically through UKAS accreditation, which is a prerequisite for many major clients. BES is type A accredited, which is preferred, they can provide highly objective opinions.
