Tank Inspection and Maintenance
Acuren has the equipment and certified professionals ready to efficiently carry out comprehensive API and non-API tank inspections, including those governed by API 653 standards. We inspect tanks of any material or size—large diameter, small diameter, vertical, or horizontal—with precision and reliability.
Our Experience
in Numbers
- Laser Scanning
- Fitness for Service
- Rope Access
Laser scanning provides a fast, accurate, and cost-efficient approach to API 653 tank inspections.
Laser scanning captures millions of data points in a single scan, allowing inspectors to quickly and accurately assess settlement, deformation, and perform volumetric calibration (strapping).
This technology produces high-resolution visuals and a permanent 3D model of the tank’s current condition—providing a valuable baseline for future inspections. The data is verifiable, repeatable, and can be exported to tools like Excel, AutoCAD, and SolidWorks. It also supports advanced engineering analysis such as Finite Element Analysis (FEA).
The result: faster inspections, better data, fewer shutdowns, and smarter long-term maintenance decisions.

Ensure Compliance and Avoid Downtime with API-Based Fitness-for-Service Assessments
Acuren offers comprehensive Fitness-for-Service (FFS) assessments for storage tanks, adhering to API 579-1 / ASME FFS-1 standards. These evaluations determine whether a tank with existing flaws or damage can continue safe operation, potentially eliminating the need for hydrostatic testing after major repairs. By employing advanced techniques like finite element analysis and rigorous stress evaluations, Acuren ensures compliance with API 653 requirements, helping clients avoid unnecessary downtime and reduce costs. In one instance, Acuren's FFS methodology saved a client over $100,000 and 30 days by exempting a large crude storage tank from hydrostatic testing.

Finite Element Analysis Saves Client $500K and 60 Days
When a client faced significant bottom settlement in an aviation fuel tank—exceeding API 653 limits—they anticipated a costly and time-consuming repair process, estimated at two months and approximately $500,000. Acuren proposed an alternative: employing Finite Element Analysis (FEA) to assess the tank's structural integrity. By creating a detailed FEA model with over 26,000 elements, Acuren demonstrated that the tank's stresses remained within allowable limits, eliminating the need for repairs. This approach reduced the project's duration to one week and costs to under $20,000, saving the client over $500,000 and 60 days of downtime.
