Detail information about job EngD - Corrosion Damage Effects on the Structural Integrity Assessment of Offshore Structures. Terms and conditions vacancy

An important issue to be considered in the structural integrity assessment of offshore structures, such as offshore wind turbines and Oil & Gas pipelines, is the characterisation of material degradation due to environmental damage and its subsequent effects on the remaining lifetime predictions. The main aim of this project is to investigate the importance of corrosion and corrosion-fatigue damage in the structural integrity assessment of offshore steel weldments (i.e. base metal, heat affected zone and weld metal) using experimental testing and numerical modelling techniques. S355 structural steel weldments, which are widely used in offshore industry, will be exposed to different corrosive environments for various durations and the corresponding changes in the mechanical response, fracture and fatigue crack growth behaviour of the material will be examined. Furthermore, a numerical model will be developed and validated to predict corrosion pitting, corrosion weight loss and corrosion-fatigue crack growth behaviour in S355 weldments in the seawater environment. This project is a joint collaboration between the Renewable Energy Marine Structures (REMS) Centre for Doctoral Training (www.rems-cdt.ac.uk) and the University of New South Wales (UNSW). The results from this project will be employed in the remaining life assessment of offshore structures and are expected to have an impact on reducing the inspection and maintenance costs for offshore structures by proposing a new design-for-purpose technique to improve the integrity of offshore welded structures. 

This is an EngD project within the Renewable Energy Marine Structures (REMS) Centre for Doctoral training (CDT). REMS is an EPSRC funded Centre for Doctoral Training set up to train fifty Engineering Doctorate and PhD students over an eight-year period. Interested applicants should send an up-to-date CV to Dr Ali Mehmanparast ([email protected]). The candidate will need to meet the academic requirements for enrolment for the EngD degree at Cranfield University; an upper second or first (or equivalent) in mechanical engineering or related discipline. Student eligibility criteria for EPSRC funding require a relevant connection with the UK, usually established by residence. EU students may be eligible for a fees-only award (i.e. no maintenance grant). A strong background in fracture mechanics, materials behaviour, experimental testing and finite element modelling is required for this project.
