Thesis title: Risk-based Evaluation Framework of Sustainable Energy Technologies
Project description: The aim of this research project was to devise a risk-based evaluation framework for sustainable energy technologies towards better informed power generation planning taking into account a number of uncertainties and risks (in terms of costs, renewable energy policy, CO2 emission reduction targets, energy security and resilience). Emphasis was placed on quantifying the trade-off between the total risk and cost per kWh of electricity generation and subsequently an overall risk metric for each technology. The risk-based methodology framework incorporated stochastic programming methods aiming also at the determination of optimum power generation portfolios towards the attainment of 2030 and 2050 energy policy targets.

Thesis title: Development of a Framework for the Effective Data Management of Structural Health Monitoring Systems for Offshore Wind Turbines
Project description: In 2007 the EU set particular and challenging goals to all Member Estates, establishing that by 2020 the UK must produce the 15% of their energy consumption from renewable energy sources.
Offshore wind can contribute towards this target achievement in many ways. SHMS are being installed offshore however, the necessary frameworks for processing and utilising in a profitable way the huge amount of data that Structural Health Monitoring Systems collect from the offshore emplacements, have not been developed yet and constitute the gap of knowledge this project aims to accomplish. Therefore the main aim of this project was to develop a framework for the effective data management of Structural Health Monitoring Systems for offshore wind turbines.

Thesis title: Development, Implementation and Assessment of Constitutive Models for Finite Element Analysis of Offshore Foundations
Project Description: Finite element analysis (FEA) is a powerful tool widely used for the analysis of geotechnical problems. A fundamental element of FEA is the selection and use of a suitable constitutive model. Given the complexity of real soil, a single all-encompassing constitutive model, which can be calibrated from a reasonable number of laboratory tests does not exist. Therefore, over the last 50 years a significant number of constitutive models have been proposed in attempt to capture the most salient features of natural soil. The practical use of many of these models is limited and many incorporate somewhat arbitrary empirical extensions to capture important aspects of soil behaviour. This DEng project developed and implemented practical constitutive models suitable for capturing the effects of overconsolidated soils (i.e. dry side of critical state), which can be used for the FEA of offshore foundations. An extensive research laboratory testing programme was completed on undisturbed samples to assist the development of the constitutive models.

Biography: Trevon Joseph is a Chartered Senior Engineer from Atkins Ltd. who specializes in Offshore Geotechnics. Trevon studied Civil Engineering for his Bachelor’s Degree at the University of the West Indies in Trinidad before taking a Master’s Degree in Engineering Seismology in France and Italy. Trevon worked for Atkins Ltd. as an Offshore Engineer for the last 10 years where, and before joining the DEng Program, he was Project Manager and Geotechnical Team Leader on a number of complex and challenging offshore renewables and Oil and Gas projects. He specialises in the foundation design, particularly for jacket piles, monopiles, as well as the design of shallow foundations such as gravity based structures and suction caissons. Trevon was a EPSRC funded student enrolled on the DEng program at Oxford, with support from Atkins.
Current employer: Ramboll UK Limited
Position: Lead Offshore Geotechnical Engineer
Thesis title: Axial Response of Offshore Jacket Piles Supporting Wind Turbines
Project description: Trevon’s research focused on assessment of current industry based pile design methods for offshore jacket structures, with a focus on open ended steel piles. Each method adopts a slightly different approach for estimating pile lengths when used for the support offshore wind turbines. The reliability of each method varies depending on soil conditions. This DEng research project has improved the reliability of these methods and consequently their application in industry.

Thesis title: Multi-objective and Multi-criteria Decision Making on Offshore Wind Farm Location and Support Structure
Project description: This PhD research aimed to devise and apply a methodology integrating Multi-Objective Optimisation and Multi-Criteria Decision Making methods along with industrial experts’ insight in order to make more informed decisions and increase the confidence in strategic investments. An optimum offshore wind farm location based on different physical and economic aspects was selected by combining a series of optimisation methods. In addition, the best offshore wind turbine support structure for that location was selected through decision making methods and experts’ opinions in every stage of the process.

Thesis title: Numerical Modelling of Laterally Loaded Monopiles
Project description: Monopiles are a commonly used foundation for supporting offshore wind turbine structures. It is now widely accepted that current design methods for laterally loaded piles may not be representative for these large diameter piled foundations. Recent work by the PISA Joint Industry Project has demonstrated that more reliable predictions of monopile response are possible, but at the expense of adopting more advanced design methods. This DEng research project developed numerical modelling techniques typically available to the design consultant, applied to monopile problems. The work focused on soil conditions encountered in the North Sea and has provided recommendations of different approaches that can be adopted for design. The project has improved understanding of failure mechanisms associated with laterally loaded monopiles.
