Predictive Analytics

As a crucial step in the integrated date journey, our predictive software help ensure continued pipeline integrity by measuring spill impact potential and overall risk along pipelines. Data alignment for accurate streamlining of reports also contributes to using data to foresee the future of pipeline integrity.

Integrity Plus by MISTRAS helps ensure that data is used to predict the future of integrity by utilizing a geographic information system (GIS). Combining PCMS or a GIS' advanced engineering capabilities with access to historical inspection data, MISTRAS works with clients to prioritize potentially high-risk problem areas. Predicting pipeline risk and spill potential allows problems to be mitigated before failure can occur.

Storage Tank Non-Destructive Testing (NDT) Inspection Services

We use a wide range of advanced NDT techniques for aboveground and underground tanks and all of their individual components, including floors, welds, annular rings, roofs, shells, and more.

MISTRAS inspects tanks throughout all phases of their operational lives, encompassing their construction, inspection, and maintenance. Our inspections help tank operators identify signs of damage, including corrosion, leakage, cracking, and wall thinning.

Our NDT tank inspection techniques and services include:

In-Service, Intrinsically Safe (IS) Storage Tank Inspections

Our customized, non-intrusive tank inspection services — which include the use of an intrinsically safe (IS) probe —maximize safety by allowing owners to determine the relative condition of their storage tanks without sending technicians into the asset.

MISTRAS’ in-service, IS scanning service is a reliable, environmentally-conscious, and safe tank inspection method, primarily used for ultrasonic wall thickness measurements. These inspections allow tank owners to postpone a full out-of-service inspection until a more appropriate time, reducing costs, downtime, and lost profits.

Additional benefits of this tank scanning service include:

  • Tanks stay in service
  • Personnel and environmental exposure to hazardous product is minimized
  • Accurate corrosion rate assessment
  • Hazardous waste disposal costs are minimized or eliminated
  • Environmental and operational liabilities are significantly reduced

TankPAC™ – Tank Bottom Condition Assessment

TankPAC™ is a surveying tool designed to assess the tank bottom condition in aboveground storage tanks (ASTs).

TankPAC is an in-service test that utilizes AE transducers that are mounted on the outside of the tank wall to listen to the active corrosion inside the tank. Based on the test results and the resulting grade given to the tank, the owner/operator can decide whether or not it is necessary to open the tank for decontamination and internal inspection.

In addition to detecting active corrosion, TankPAC’s AE technology can also be used for detecting and locating active leaks.

TankPAC helps tank operators optimize their maintenance budgets, as it has shown that tanks are often opened unnecessarily, leading to unnecessary downtime and lost productivity.
