In an article on the ASCO website, John Davidson, Operations Manager – Environmental Services, ASCO discusses how the UK’s experience of building a system to deal with Naturally Occurring Radioactive Material (NORM) can benefit Australia.
Davidson points out that as Australia faces a massive decommissioning wave, dealing with NORM will be one of the challenges it will need to address. This residue, which builds up in pipework, tanks and separators over years of oil and gas production, carries radiological risks and requires expert handling, treatment and disposal.
In the UK, the oil and gas sector has been dealing with NORM for decades, although the early years were challenging, he notes. “But through trial and error, the UK built a system that now works,” he says.
“NORM processing was centralised. Long-distance, highly regulated transport systems were developed. Experienced specialists were embedded into local teams. Most importantly, collaboration gradually replaced competition. Today, the UK has one of the most mature decommissioning supply chains in the world.”
Australia has a chance to avoiding years of inefficiency and unnecessary cost by learning lessons from the UK experience, he suggests. ASCO, which has built and operated one of the world’s most advanced NORM facilities in the North Sea, can now transfer that knowledge directly into Australia.
He goes on to suggest that a logistics strategy to deal with the long distances of offshore assets from disposal sites needs to be put in place; the expertise of experienced specialists should be leveraged at an early stage; and collaboration between companies should be encouraged, with shared infrastructure, expertise and logistics creating efficiencies and helping to address gaps in local capabilities.
On the questions of regulation, he notes that UK authorities engaged closely with industry to co-develop standards and best practice. “The UK’s lesson is clear: proactive engagement builds trust, accelerates approvals and avoids gridlock.”
“If Australia can absorb the lessons above now, rather than repeat the UK’s early missteps, it has the opportunity to build one of the world’s most resilient and effective decommissioning supply chains,” he concludes.
