Bureau Veritas performs unique Computerised Radiography NDT method on the Northern Gas Pipeline

Computerised Radiography: Bureau Veritas performs NDT on the Northern Gas PipelineBureau Veritas performed NDT using a unique Computer Radiography (CR) method which contributed to the construction of 481km of the Northern Gas Pipeline (NGP).

In 2017, McConnell Dowell was commissioned by Jemena to construct 481km of the Northern Gas Pipeline (NGP). Bureau Veritas was brought in to become a partner and contribute extensive overseas experience to the project. Bureau Veritas’ Commercial Director Ross McNeil and National Technical Manager Hamid Fard worked with the team to develop ideas fulfilling the project’s requirements.

In Australia, the pipeline welding code, AS2885.2, mandates either radiography or ultrasonic testing for NDT of welds and the recommended method of radiography is X-ray radiography using films.

Instead of a film, with Computer Radiography (CR), a reusable photostimulable phosphor imaging plate is used to capture the image of the weld when exposed to the X-ray source. The image plate is then sent through a special high-resolution scanner, which converts the image on the plate to a digital image that is then viewed on a monitor. The image on the plate is erased when it passes through the scanner.

The advantages offered by this CR method over films are:
- Shorter cycle times than film enabling faster results.
- Shorter exposure times resulting in less battery changes.
- Increased probability of detection, better sensitivity than film (at least one wire better).
- No chemicals for film processing to dispose of.
- Digital data sharing capability made possible.
- No quality degeneration on long-term data storage.
- Lower data storage costs.
- Ability to enhance images electronically.
- Better reporting due to automation and lower consumable costs due to reusable plates.

Bureau Veritas invested in the high initial setup costs of the computerised radiography method, as well as produced the qualification and validation report. The project endured the peak of summer, as Bureau Veritas air freighted special high-temperature resistant plates to meet the challenges of extreme temperatures in the region.
