Delayed Coker Units (DCUs) process over 10% of the world’s crude oil, yet their extreme thermomechanical fatigue makes them a refinery’s highest-risk asset. For the Mechanical Integrity Team and Reliability Managers, the challenge is clear: how do you quantify damage and predict failure in an environment of random localized thermal gradients? 

Vessel Inspection and Assessment (US) Corp. (VIAAC) transforms high-fidelity inspection data into actionable engineering intelligence. We help refineries move from reactive emergency repairs to proactive, data-driven maintenance strategies and optimization.

Our Differentiators:

Actively Stabilized 3D Laser Scanning: Unlike un-stabilized equipment that relies on "data smoothing," our proprietary platform captures the true as-found conditions of the vessel without motion-induced artifacts.

Unmatched Operational Speed: We complete a comprehensive inspection—including setup and removal—in under 4 hours. This is 50% faster than industry standards, directly minimizing production losses.

Predictive Engineering (LPSI™): Our API 579-compliant tool goes beyond simple measurement to rank bulge failure risks. Calibrated against real-world failure data, we forecast repair timelines from 6 months to 4+ years.

VesselViewer™ Program: A secure "Single Source of Truth" that consolidates historical inspections, operations data, and living "Likelihood of Failure" scores for your entire fleet.

Proven Global Expertise
Founded by the world’s most experienced coke drum inspectors, our leadership brings:
- 870+ Laser and Visual Inspections completed globally.
- 9 ASME Technical Papers authored on coke drum damage phenomena.
- Trusted Partnerships with majors including ExxonMobil, Marathon, Saudi Aramco (YASREF), and IOC.
