Deployment Strategy, Not Technology, Is the Weak Link in Ultrasonic Corrosion Monitoring
According to Inspectioneering Journal, the biggest barrier to effective continuous corrosion monitoring using ultrasonics is not the technology itself, but the strategy used to put it in the field. Writing in the May/June 2026 issue, William Vickers, PhD, Director and Monitoring SME at Ionix Advanced Technologies (a vendor in this space), argues that ultrasonic corrosion monitoring is now a mature and capable technology, yet adoption across operating facilities remains inconsistent. The reason, he contends, is deployment practice, not measurement capability.
Background
Ultrasonic testing has long been a workhorse of nondestructive examination in oil and gas, refining, and petrochemical facilities. The ability to measure wall thickness from the outside of a pipe or vessel without taking equipment offline has made it a preferred tool for assessing corrosion in pressurized systems.
What Vickers addresses in the Inspectioneering Journal piece is the gap between what the technology can do and what facilities are actually getting out of it. According to the article, conventional project-led approaches to deploying these monitoring systems are often too slow and too complex to respond to emerging integrity risks. The practical result is that critical maintenance and inspection decisions end up being made without current data, which defeats much of the purpose of continuous monitoring.
The article points to shifts in plant operating economics as part of the pressure driving this problem. Facilities are being asked to do more with less, and the window between identifying a risk and needing an actionable response has narrowed.
What’s Actually Driving the Shift
The argument Vickers makes is fundamentally about the mismatch between how monitoring technology is procured and how integrity risk actually behaves in the field. Risk doesn’t wait for a capital project cycle. Corrosion under insulation, erosion at a pipe elbow, or accelerated degradation in a high-temperature service line can develop faster than a traditional planned inspection program is designed to catch.
The solution the article points toward is a move from planned, project-driven implementation toward what it describes as responsive deployment, putting monitoring capability at the point where risk is identified, when it is identified. This is enabled, according to Vickers, by recent developments in low-infrastructure hardware and service-led delivery models that make rapid deployment more practical than it has historically been.
That framing has real implications for how inspection and integrity services are sold and structured. If the technology can be deployed quickly and without heavy infrastructure investment, then the competitive advantage shifts away from whoever owns the most sensors and toward whoever can respond fastest with the right deployment strategy. Speed, flexibility, and a clear process for acting on the data become the differentiators.
There is also a cost argument embedded here. The article notes that responsive deployment supports earlier intervention and can reduce inspection and access costs. In practice, that means fewer scaffolding builds, fewer confined space entries, and fewer shutdowns driven by uncertainty rather than confirmed data. For facilities running lean maintenance teams, that is a significant operational benefit.
The broader shift the article describes is from time-based inspection toward what it calls events-based maintenance, meaning facilities move resources and monitoring attention based on process changes, upsets, or other triggers that indicate elevated risk, rather than inspecting on a fixed calendar. Continuous ultrasonic monitoring is a key enabler of that model, but only if it can be deployed at the pace that operational conditions demand. US facilities operating under OSHA Process Safety Management (PSM) and EPA Risk Management Program (RMP) requirements are increasingly looking at data-driven inspection models to satisfy mechanical integrity obligations without expanding headcount.
What It Means for Subcontractors
-
Deployment capability is becoming a differentiator. If clients are moving toward responsive, risk-driven monitoring rather than scheduled inspection campaigns, subcontractors who can mobilize ultrasonic monitoring quickly, with minimal site infrastructure requirements, will have a competitive edge over those locked into traditional project timelines.
-
Service-led models are gaining ground. The article specifically references service-led delivery as part of what makes rapid deployment feasible. For inspection and integrity firms, this points toward offering monitoring as an ongoing service rather than a one-time installation, which also creates more stable recurring revenue.
-
Know the deployment strategy, not just the technology. Field service providers recommending ultrasonic monitoring systems to clients need to be able to speak to how and where sensors will be placed, how data will be acted on, and how the system will respond when conditions change. Selling the sensor without the strategy is increasingly the wrong conversation.
-
Events-based maintenance is a selling point. Clients under pressure to cut inspection costs without increasing risk are receptive to the idea of deploying resources based on actual conditions rather than fixed schedules. Subcontractors
