Applus+ has provided comprehensive inspection services in support of the repair, upgrade, and subsequent reuse at a seismic activity-impacted refinery in Papua New Guinea. Following the major earthquake in February 2018, a thorough inspection was essential to ensure the successful restoration and enhancement of the facility.
The scope of work covered tank inspection, pressure vessel inspection, and piping inspection per API standards. We also performed various non-destructive testing (NDT) methods on piping, structural, new tank construction, and 3.6 km of pipeline from the central processing facility (CPF) to the refinery.
One of the notable methods used is magnetic flux leakage (MFL). By utilising MFE Mark IV, we provided accurate screening for underfloor corrosion on tank floors. This approach allowed the client to focus their resources and efforts on the areas most affected by corrosion rather than inspecting the entire tank floor -unnecessary downtime is minimised, making the inspection process more efficient and cost-effective.
This was the first time Applus+ in PNG has undertaken the entire inspection package, encompassing tanks, pressure vessels, piping, and the pipeline connecting CPF and the refinery. While it poses a significant challenge, we delivered the services consistently and reliably by leveraging our global pool of expertise and experience.
