TWI employee and former NSIRC PhD candidate, Hadi Khalili has had his research published in the Journal of Marine Science and Engineering (JMSE).
Hadi’s PhD research investigated improvements to structural reliability assessments using Bayesian methods. His research looked into fatigue damage in offshore platforms, including updating the probability of distribution and estimating joint reliability by incorporating the inspection results.
The paper developed a framework to update the probability distributions of all uncertain parameters involved in the fatigue crack growth analysis. This methodology maximises the benefit of the inspection results by updating several uncertain parameters involved in the fracture mechanics approach. To demonstrate the developed framework, a tubular joint in a specific jacket platform is considered and the framework is applied for that joint.

Hadi’s supervisor at TWI was Dr Ujjwal Bharadwaj, with co-supervision provided by Selda Oterkus and Nigel Barltrop from the University of Strathclyde, and Mark Tipping from Lloyd’s Register. The publication was made possible by the sponsorship and support of Lloyd’s Register Foundation. The work was enabled through, and undertaken at, the National Structural Integrity Research Centre (NSIRC), a postgraduate engineering facility for industry-led research into structural integrity established and managed by TWI through a network of both national and international Universities.
