What NDT Is

Nondestructive testing (NDT) comprises a wide group of analysis techniques used to evaluate the properties of a material, part, product, weld, or system without materially affecting the integrity of the unit under test.

Why It Matters

These techniques can identify and assess defects and examine the properties of all kinds of materials and structures without causing any damage. As NDT in no way alters the part or structure under inspection, it is an extremely useful technique that can lead to cost and time savings when applied to product evaluations, asset management and fault identification and repair.

Asset Risk Management System

A new breed of application offering real-time event notification around a sophisticated suite of analytics infused with our expertise in asset life-cycle and associated risks. Our on-line solution provides intelligent alerts and event notification so organizations can make more informed decisions between times of crisis and long-range operational planning.

Beyond Condition-Based Maintenance

With our on-line solution, companies can move beyond traditional notions of condition-based maintenance, allowing employees to think more strategically about managing risks. It is a cost-effective tool for monitoring assets across the enterprise — reducing unplanned shutdowns, boosting production, increasing operational efficiency and decreasing maintenance costs.

The Right Level of Detail

Too few or too many details — those are the typical complaints about most asset management systems. Asset managers need to know when a "notification" is a real or developing problem, and which asset needs the most attention. Our solution combines real-time with online and offline data sources, then compares the analytic results to decades-worth of benchmark data on asset performance.

A Clear View of Asset Health

Instead of wasting critical time searching for the right information, our on-line solution searches for the needle in the haystack — an asset event — and rolls up the salient details to a higher level, offering a consolidated geospatial view with clear, visual understanding of asset condition, criticality and risks, with the power to drill down to the specifics you need.

Summary

The solution pulls in on-line and off-line data sources, comparative data, advanced analytics and consideration of risk factors like load, cost and customers interrupted. It turns thousands of individual data points — everything from dielectric tests to operational data — into actionable information you can use to make critical decisions about day-to-day and long-term operations.
