Tank Monitoring

MISTRAS offers a range of comprehensive non-destructive testing (NDT) solutions for accurate and timely aboveground storage tank (AST)condition-monitoring in oil & gas, manufacturing, civil infrastructure facilities.

Our technicians implement monitoring programs that combine non-destructive testing (NDT) technology with Risk-Based inspection (RBI) solutions and services in order to ensure that storage tanks maintain both structural and operational integrity while remaining in regulatory compliance. Our monitoring solutions are non-intrusive, allowing:

• No interruptions to tank service or condition
• Cost savings from avoiding tank openings
• Improved safety & quick results
• Planned internal inspection strategies

We offer a variety of traditional and advanced NDT methods to monitor tanks internally and externally for damage and corrosion, assessing various parts of the tank within centralized and comprehensive programs, assessing componentry such as:

• Annular Rings
• Tank Bottoms
• Tank Floors
• Tank Roofs
• Tank Shells

Monitoring for Tank Defects

Storage tanks are subject to both internal and external defects that can have serious consequences for the mechanical and operational integrity of the asset. When built up over time, small defects can accumulate into large-scale damages that cause your facility to experience unplanned shutdown and costly downtime.

MISTRAS has monitoring solutions that detect storage tank defects in real-time, helping operators stay constantly updated on their asset’s condition and improve planning for future repairs and maintenance. Our NDT technology can detect and locate a wide range of faults, including, but not limited to:

• Corrosion
• Leaking
• Cracks
• Pitting
• Insufficient Wall Thickness
• Weld Defects
• Structural Deficiencies

MISTRAS also offers maintenance and access services to install monitoring sensors at any location on a storage tank, by accessing hard-to-reach locations with rope access teams or scaffolding.

TankPAC™ Condition Floor Assessment and Monitoring

MISTRAS’ TANKPAC™ is not an inspection method, but a “sorting” system that separates “good” tanks from “bad,” and directs maintenance to where it’s most needed.

Following a period of conditioning during which valves are closed and heaters/agitators turned off, highly-sensitive acoustic sensors are attached to the tank wall and the tank is monitored. The fracture of corrosion products is detected along with leaks that are active during the actual monitoring period. A percentage of this data is located by triangulation, but the most important information gained from a maintenance management point of view is the overall condition of the floor, which is given a grading on an scale of “A” to “E.”

TANKPAC™ helps to set inspection priorities and intervals based on floor condition, and fits in well with risk-based inspection strategies.
