3 Resources to Understand the Future of Drone-Based PEC for CUI

Corrosion under insulation (CUI) is one of the costliest challenges in industrial maintenance—accounting for up to 60% of piping-related expenses. Traditional inspection approaches require scaffolding, insulation removal, and significant downtime. But with drone-based PEC inspections, we’re entering a new era of safety, efficiency, and digital transformation.

In this edition, we’ve curated three essential resources that show why drone-based PEC inspections are the future of CUI.

Resource 1: Case Study: 90% Cost Savings in CUI Inspection

In a first-of-its-kind mission, Osprey Integrity deployed the Voliro T drone with PEC sensor at a Canadian refinery.

• 90% cost reduction per inspection point (saving ~$18,000 CAD each)
• No downtime required, as inspections were conducted with insulation in place
• Traceable digital results enabled smarter decision-making

Resource 2: Guide 2025 to Corrosion Under Insulation (CUI) Solutions (Causes, Detection, and Prevention)

Need a refresher on what causes corrosion under insulation—or how to detect it without disassembly or downtime?

Our guide breaks down:

• Why CUI is so destructive (and expensive)
• Where it tends to hide across process infrastructure
• The pros and cons of major detection methods, including PEC, radiography, IR, and UT
• How to build a smarter, more proactive CUI inspection strategy

Whether you’re an asset owner, integrity engineer, or inspection service provider, this guide gives you the context and tools to take action.

Resource 3: Are Drone-Based PEC Inspections the Future?

CUI inspections account for 40–60% of piping maintenance costs in heavy industries. The challenge has always been accessing data beneath insulation—until now.

The release of the Voliro T with PEC sensor enables:

• Remote data collection without scaffolding
• Faster, safer, and more cost-efficient inspections
• A leap forward in operational reliability and digital transformation
