    Numerical modelling of offshore floating structures;

    Overview

    Profile summary

    My current research mainly focuses on the low carbon construction materials, particularly the application to offshore floating platforms. I am currently the PI for a Royal Society funded project "Fatigue failure mechanics of carbon-fibre textile reinforced concrete (CTRC) in the marine environment", to test the flexural fatigue behaviour of CTRC beams under seawater. I’m a Co-I (WP5 lead) of an EU funded project “Light-Weight High Performance Concrete for Modular Floating Structures – LITEFLOATCON”, to develop innovative light-weight high performance concrete and investigate its application on multi-purpose modular floating structures for marine space utilisation, where my responsibility is to lead the numerical simulation of coupled fluid-structure interaction of large floating concrete modular systems and investigate effects of various connectors on the overall structural performance of the modular system. I’m also a Co-I for EPSRC funded project “FlexWave – flexible responsive systems in wave energy (EP/V040367/1)”, where I’m responsible for finite element analysis of the flexible wave energy converters under wave loading.

    I was the coordinator for an EU funded project “Tailor-made recycled aggregate concrete - TRAC” which aimed to promote the use of recycled aggregates in civil infrastructure. I was also the PI for an EPSRC funded Supergen ORE ECR award “Offshore floating foundations using self-sensing carbon fibre textile reinforced concretes”, to test the dual-functional properties of using carbon-fibre textiles as both reinforcement and sensor in concrete structures, and PI for a University of Plymouth Sustainable Earth Institute funded project “Use of tungsten tailing waste as replacement for cement” to investigate the feasibility of using tungsten tailings in making low carbon concrete materials.
