Bottom Floor Profiling by Acoustic Emission Testing is an advanced inspection technique used to assess active corrosion and deformation in storage tank floors while the tank remains in service. This method detects stress waves generated by corrosion activity, cracking, or material deformation, allowing real-time evaluation of tank floor condition.
Acoustic emission testing is particularly valuable for screening tanks and prioritizing further inspection or maintenance activities.
Why Acoustic Emission Testing Is Required
In-service tanks cannot always be taken out of operation for inspection. Acoustic emission testing enables condition assessment without draining the tank, reducing operational disruption and inspection cost.
This technique helps identify areas of active corrosion and supports risk-based decision-making.
Scope of Inspection
Acoustic emission testing is applicable to:
In-service above-ground storage tanksTank bottom plates and annular regionsLarge diameter tanks requiring screening inspection
Inspection Methodology
Acoustic emission testing is performed by installing sensors around the tank perimeter to capture stress-generated acoustic signals. During controlled loading or normal operating conditions, acoustic emissions from corrosion or deformation activity are recorded.
The collected data is analysed to identify active corrosion zones and assess floor condition trends. Results are used to prioritize tanks for detailed inspection or maintenance intervention.
Key Benefits
Acoustic emission testing enables in-service inspection, identifies active corrosion, reduces downtime, and supports effective inspection prioritization.
Industries and Applications
This service is widely applied in refineries, oil terminals, petrochemical facilities, chemical plants, and storage installations operating large above-ground tanks.
Bottom Floor Profiling by Acoustic Emission Testing provides a non-intrusive and efficient method for evaluating tank floor integrity. By detecting active corrosion without taking tanks out of service, this service supports proactive asset management.
