Estimating Metocean Environments Associated with Extreme Structural Response to Demonstrate the Dangers of Environmental Contour Methods
Matthew Speers, David Randell, Jonathan Angus Tawn +1
Extreme value analysis (EVA) uses data to estimate long-term extreme environmental conditions for variables such as significant wave height and period, for the design of marine str…
Temporal evolution of the extreme excursions of multivariate th order Markov processes with application to oceanographic data
Stan Tendijck, Philip Jonathan, David Randell +1
We develop two models for the temporal evolution of extreme events of multivariate th order Markov processes. The foundation of our methodology lies in the conditional extremes…
On environmental contours for marine and coastal design
Emma Ross, Ole Christian Astrup, Elzbieta Bitner-Gregersen +8
Environmental contours are used in structural reliability analysis of marine and coastal structures as an approximate means to locate the boundary of the distribution of environmen…
Statistics of extreme ocean environments: Non-stationary inference for directionality and other covariate effects
Matthew Jones, David Randell, Kevin Ewans +1
Numerous approaches are proposed in the literature for non-stationarity marginal extreme value inference, including different model parameterisations with respect to covariate, and…
Bayes linear variance structure learning for inspection of large scale physical systems
David Randell, Michael Goldstein, Philip Jonathan
Modelling of inspection data for large scale physical systems is critical to assessment of their integrity. We present a general method for inference about system state and associa…
Avoiding methane emission rate underestimates when using the divergence method
Clayton Roberts, Rutger IJzermans, David Randell +5
Methane is a powerful greenhouse gas, and a primary target for mitigating climate change in the short-term future due to its relatively short atmospheric lifetime and greater abili…
