The detectives of corrosion

Corrosion costs the oil and gas industry billions of dollars every year, it can also have far reaching environmental consequences. But so far no one has managed to stop corrosion happening.

A detective style research team based at The University of Nottingham Malaysia Campus are working closely with industry to investigate real world problems and are taking a forensic look at the nature of corrosion — particularly in the oil and gas sector.

Dr Andrew Spowage, Director of Studies in the Department of Mechanical, Materials and Manufacturing, is an expert in characterisation and testing of materials. He said: “It is a little bit like CSI if you like but it isn’t quite as glamorous. We collect samples, put things in bags and bring them back to our labs for analysis.”

Corrosive fluids eat away iron. On pipelines across the world this constant assault can erode the surface of the pipe and the protective layers. The damage can lead to a failure in the mechanical strength and integrity of the pipe. When that happens, the end result could be mechanical failure with the potential risk of the contents of the pipe spilling out into the environment. 

Forensic style investigation

When problems like this are detected Dr Spowage and his team are despatched to the scene — often to oil rigs off the Malaysian coastline — to collect the evidence, establish a cause and make recommendations for remedial action.

Dr Spowage said: “The damage is not always easy to detect and access can be difficult but we prefer our customers to leave the pipe intact so we can see the real situation. We remove samples from the surface of the pipe, together with samples of the corrosive products. In our laboratories we use advance characterisation techniques to understand more about these samples. By relating this information back to the corrosion processes and production data we try to find out what has been going wrong.

“There is only so much you can do using these techniques so what we also do is try to replicate the conditions in the pipe. If we can replicate the conditions and produce the same type of corrosion products on the surface of the pipe we can offer better advice on how to mitigate the problem and prevent it from happening again.”

Understanding more about corrosion

In each case the conditions may vary but the standards for welding are the same and the materials are all the same so these are problems which affect the oil and gas industry worldwide. In search of a solution to the problem Dr Spowage and his team also use real live samples that arrive in their laboratories to conduct further research to help us understand more about the phenomenon of corrosion.

Notes to editors: The University of Nottingham, described by The Sunday Times University Guide 2011 as ‘the embodiment of the modern international university’, has 40,000 students at award-winning campuses in the United Kingdom, China and Malaysia. It is ranked in the UK's Top 10 and the World's Top 75 universities by the Shanghai Jiao Tong (SJTU) and the QS World University Rankings. It was named ‘the world’s greenest university’ in the UI GreenMetric World University Ranking 2011.

More than 90 per cent of research at The University of Nottingham is of international quality, according to the most recent Research Assessment Exercise. The University’s vision is to be recognised around the world for its signature contributions, especially in global food security, energy & sustainability, and health. The University won a Queen’s Anniversary Prize for Higher and Further Education in 2011, for its research into global food security.

Impact: The Nottingham Campaign, its biggest ever fund-raising campaign, will deliver the University’s vision to change lives, tackle global issues and shape the future. More news
