Optimising Turnaround Maintenance (TAM) Scheduling of Gas plants in Libya
… requirements of gas plants according to the residual life of critical equipment and operating conditions. To ensure reliability and consistency of the TAM model, it was validated with three Libya-plants SOC and data from three published case studies. The results from the validation of the TAM …

High Cycle Fatigue Simulation using Extended Space-Time Finite Element Method Coupled with Continuum Damage Mechanics
… (UNSM) and many others introduce significant residual stresses in the material, which drastically affects the fatigue life. Motivated by the need for effectively incorporating the residual stress effect in the fatigue life prediction, two approaches are developed in this thesis.In the first …

Probabilistic deterioration modelling and time-dependent reliability analysis of coastal defences
… are available in order to estimate structures residual life with respect to the structural conditions. However, probabilistic approaches to model the stochastic deterioration process with consideration of the changes in hydraulic loading parameters are not studied yet in coastal flood defences. …
