This Level 1 and 2 combined package for Corrosion Under Insulation (CUI) provides the foundation knowledge and competency required for visual inspection of asset integrity threats. It also provides a guide to managing the risk in onshore and offshore facilities.

Level 1

Corrosion Under Insulation (CUI) is one of the biggest asset integrity threats on onshore and offshore plants costing millions of pounds each year. This online course was developed by INSPECTEGRITY in a project supported by the Oil & Gas Technology Centre (OGTC) and will be enable delegates to:

  • Understand how CUI occurs
  • Understand why CUI is such a threat to Asset Integrity
  • Know where to look and what to look for - able to identify a potential CUI location

Who should attend:

The CUI e-Learning package will be useful to Inspection personnel; Plant inspectors; Offshore inspection Engineers; Inspectors; NDT Technicians; but is also relevant to other non-inspection personnel, such as FM;  maintenance; operations or other asset management teams.  It is applicable to both onshore and offshore facilities.

Course Overview

  • What is CUI?
  • Where does CUI occur?
  • Why does CUI occur?
  • Consequences of a CUI failure
  • Costs of CUI
  • What is the mechanism of CUI?
  • Cyclic changes of temperature
  • Corrosion mechanisms
  • Potential locations of CUI
  • Signs of CUI
  • De-lagging and Safe de-lagging
  • Scab
  • Remedial works
  • Reinstatement of insulation
  • Why insulation is applied
  • Why passive fire protection (PFP)?
  • Insulation types
  • Mitigation of future risk of CUI

As a result of this online course, it is expected that personnel will be more confident that they can find asset integrity threats relating to corrosion under insulation that may be present on their plant.

Completion time

1-2 hours 

Level 2

Every year operators must budget for the control of CUI. Without understanding the CUI risk on the plant or platform, CUI budgets can often be misjudged or used inefficiently. This online course was developed by INSPECTEGRITY in a project supported by the Oil & Gas Technology Centre (OGTC) and will be enable delegates to:

Course Overview:

  • What is CUI?
  • Why does it occur?
  • Swiss Cheese Model for CUI
  • Strategies for Controlling CUI
  • Elements of CUI Campaign
  • Register of Insulated Equipment
  • Plant Wide Insulation Review
  • CUI Contributing Factors
  • Operating Temperature
  • Intermittent Operations
  • Coating Condition
  • Coating Age
  • Cladding Condition
  • PFP Weather Barrier
  • Insulation Type
  • Weather Condition
  • CUI likelihood assessment model
  • Life cycle of CUI
  • Point-based qualitative model
  • Consequence of a CUI failure
  • CUI risk
  • Priority of CUI scopes
  • Refining a CUI priority scope
  • Percentage of insulation removal
  • Using advanced NDT techniques
  • Partial insulation removal
  • Frequency of CUI scopes
  • Maintaining CUI records
  • Balancing CUI risk and costs
  • A successful CUI campaign
  • Reporting CUI inspections and repairs

Learning objectives:

  • Different CUI control strategies and their efficiencies and effectiveness
  • Contributing factors in the CUI likelihood
  • CUI risk components
  • And how to define an effective inspection and maintenance campaign-based CUI strategy with high return on investment

Course outline:

This online course is designed to provide Inspectors, asset personnel and asset management teams with the detailed knowledge to manage the CUI risk in a large onshore plant or aged offshore platform.
