Darwin LNG Plant Corrosion Under Insulation Assessment

21/08/18

Darwin LNG Plant Corrosion Under Insulation AssessmentBureau Veritas Australia was engaged by ConocoPhillips to perform corrosion under insulation assessment on 80 piping isometrics in Darwin LNG plant, where Real Time Radiography using OpenVision was utilised as the main inspection tool. For high-density insulation and pipes with diameters more than 1200mm, Pulsed Eddy Current using Eddyfi Lyft was utilised. Confirmation of the results was done by digital radiography with GE-Digital Detector Array panels. Inspection was performed on a variety of diameters ranging from DN25 to DN1350.  The majority of the project was carried out using Rope Access. Inspection reporting included corrosion categories, quantification of moisture and ice formation in the insulation. Bureau Veritas Australia is accredited to perform Real Time Radiography for CUI in accordance with ISO 17025.

The benefits if CUI Inspection methods are:

Real Time Radiography
- Very fast and reliable results
- Can detect water, ice and any abnormality in the insulation

Pulsed Eddy Current
- Effective tool to be used for screening for major corrosion.
- No coating breakdown and low corrosion wall loss.
- Very safe to use and easy to use on rope.
- Can go through any type of insulation compared to other methods
- No limitation for insulation diameter

Digital Radiography 
- Very reliable
- For less than 8”, it provides very accurate wall thickness measurement
- It provides a comprehensive and clear record
