Corrosion Monitoring

Estimates for the overall cost of corrosion relating to oil & gas, power generation and other key industries exceeds $150 billion annually. Industry estimates that 20 to 25% of these costs can be avoided by better use of existing monitoring technologies. Corrosion failures in plant infrastructure are costly to repair and result in contaminated product, environmental damage, and risks to human safety. Decisions regarding plant integrity rely on an accurate assessment of the conditions affecting corrosion and the rate of deterioration, and it’s here that ArtrA makes a significant contribution to potential cost savings.ndt_page_1

ArtrA is used as a management tool to monitor the results of all types of non destructive tests (NDT) such as radiographic (RT), magnetic particle (MT) and ultrasonic (UT). Standard corrosion monitoring results identify the pipes, fittings and welds which have reduced wall thickness and are judged to be marginal or critical. When ArtrA is used the results are shown graphically in 3D and in context with their surroundings. This leads to a better understanding of the issues and results in improved decision making.

CAPTURE TEST RESULTS. Corrosion monitoring measurements can be logged in the normal way and entered into ArtrA in the office, or entered directly into the system on site using ArtrA iTracker which runs on tablet PC’s. The field the engineers enter the results (wall thickness) into the system using a tag input form which is a far more reliable method than recording the data on paper and transcribing it later.

LINK CORROSION DOCUMENTS. All relevant documents including piping isometrics, photographs showing the extent of corrosion, historical information, previous maintenance history as well as the PDF of the NDT results can be quickly attached to the correct objects in the model.  Having all the information to hand in the field or in the office helps to increase efficiency and improves decision making.

INTERROGATE. Corrosion information in Tag’s and NDT documents in the project database can be searched for, filtered and shown graphically in in context with their surroundings. Engineers can easily drill-down into the database to find the information they need and then visually isolate the results. Important data such as nominal bore, rating, specification, system, schedule, wall thickness, etc. is readily to hand ensuring that everyone is equipped with all the necessary information.

THEMATIC VIEWS. As well as reporting corrosion results in tabular format through Excel, ArtrA will show them as 3D colour coded views. This powerful visualisation helps to identify the location of critical problems and gives a better understanding of the logistics involved. Using ArtrA thematic reports, owners and O&M staff can make informed decisions as to the type, process, cost and urgency of remedial measures.
