Research into failures in the maritime and oil & gas industries carried out by DNV GLís network of laboratories in the US, Europe and Asia has identified that, of the components examined, more than a quarter (27%) of failures occur in tubes and piping, and a fifth (20%) in rotating machinery.

Fasteners, and mooring and lifting components also appear in the top five components most prone to failure. Fatigue (30%) and corrosion (19%) make up nearly half of the primary failure types occurring in the cases DNV GL analysed. Brittle fracture, overload and wear are also in the top five.

“The cost of prevention, monitoring, repair or replacement as a result of these forms of component degradation can run into billions of dollars. Potentially, financial penalties can occur if major incidents and loss of life result from such a failure. Our experts can provide in-depth technical advice to prevent future failure on similar components that keep operations running and importantly keep the workforce safe,” said Koheila Molazemi (pictured), Technology and Innovation Director, DNV GL - Oil & Gas. 

To obtain the data for its research, DNV GL’s laboratory experts applied several methods to analyse data and documentation to assess failure trends and predict what components are most likely to fail. This included innovative approaches applying advanced search engine technologies combined with technical subject matter expertise. DNV GL continues to enhance this approach with its customers.

This systematic analytical approach means high volumes of data can be examined far more rapidly than using traditional databases and spreadsheets. 

The accumulation of more and better data and learnings from failures can be applied in the front-end engineering design phase of development projects to engineer more robust assets. During operations, says DNV GL, learnings can enhance optimisation of inspection, repair and maintenance for more efficient and safer use of capital and people.
