Research Expertise

Description

My research interests primarily relate to Geotechnical Engineering and Offshore Engineering. I have performed research in pile axial loading, lateral loading, cyclic loading, pile ageing, soil-damping and soil-structure dynamics related to offshore structures. My research includes an extensive instrumentation project for a full scale Metmast demonstrator in the North Sea. I am a member of the academic work group and was a key contributor to the Pile Stability Analysis (PISA) project, which won the prestigious British Geotechnical Association Fleming Award and was recently recognised by the UK Carbon Trust as one of the 10 most high impact projects undertaken in the last 10 years by the Offshore Wind Accelerator (OWA) program. The carbon trust program estimates it's projects will have resulted in £34 Billion cost savings for the offshore wind industry by 2030.

Projects

  • Title
    • Development of damping parameters for Irish Offshore Wind Farms
  • Summary
    • In order to achieve the greenhouse gas emissions targets set out in the Paris agreement, Ireland will need to significantly decarbonise its energy supply. Due to reducing costs, offshore wind now offers the most viable means for large scale decarbonisation of Irelands electricity supply by 2030. It is predicted that the offshore wind installation rate in Europe will increase 400% resulting in an industry worth more than €20 Billion per year in Europe alone [1]. In Ireland, it is estimated that 1.8GW of offshore wind capacity at an estimated cost of ~€4.5 billion, will be installed by 2030 [1]. One of the key challenges in the engineering design of an Offshore Wind Turbine (OWT) relates to choosing appropriate values for damping of the OWT structure. Choosing more realistic values of damping in design can lead to significant reductions in the calculated loads acting on the structure, and also large reductions in fatigue damage, which can lead to savings of up to 10% in steel weight across the structure [2]. In the Irish context this would equate to potential cost savings of ~€230m by 2030 (assuming 1.8GW of offshore wind is developed) and in excess of €1 billion per year across Europe. The primary goal of this project is to advance the scientific knowledge of OWT damping and provide accurate and realistic damping values for use in the design of Irish offshore wind farms, specific to soil types and conditions relevant for potential offshore wind development zones around Ireland.

  • Title
    • Optimisation of XL Monopiles supporting offshore wind turbines through advanced numerical modelling of cyclic loading effects
  • Summary
    • The European Union (EU) has established ambitious renewable energy targets in order to de-carbonise the energy sector. In Ireland, it is estimated that 2.3GW of offshore wind capacity will be installed by 2030 at an estimated cost of €6 billion. The foundations for offshore wind turbines (OWTs) can represent up to 30% of the overall cost of development. Among all components of an OWT structure, the foundations offer the greatest scope for optimisation. Monopile foundations, which are large diameter (typically 4 - 8m) steel tubes driven into the ground, represent around 80% of all offshore wind turbine foundations installed to date and will continue to the be the most common foundation solution for offshore wind for at least the next 15 years [1]. As larger wind turbines are being developed, XL monopiles from 8 - 12m in diameter are needed to be support these. These larger diameter piles typically have a lower slenderness (ratio of length to diameter) than standard monopiles and are therefore significantly more susceptible to the effects of cyclic loading. Because of inadequate understanding of the effects of cyclic loading, XL monopiles are currently over-designed, causing excessive manufacturing, transportation and installation costs. This project aims to improve design methods for cyclic loading effects on XL monopiles through state of the art numerical modelling and calibration against new field test data, and will lead to significant advances in scientific knowledge and improvements in the design efficiency of OWTs. Specifically this will build upon recent advances in the state of the art in numerical modelling of monopiles and a will be validated against recent monopile field test data. The ultimate goal is to reduce cost and improve the viability of the offshore energy, leading to a more rapid reduction in carbon emissions and reliance on fossil fuels.
