Career Summary

Curriculum Vitae

Dr Kieran Dodworth became Director of Naval Architecture in 2019.  He was employed in the offshore industry prior to joining Brookes Bell, working for several consultancy firms based in the UK in the area of non-linear dynamics of offshore structures.  He studied for a PhD in damaged vessel hydrodynamics at the University of Strathclyde which he achieved in 2000.  His undergraduate degree was in Naval Architecture and Small crafts from the University of Strathclyde which was completed in 1995.  His areas of expertise are in aero/hydrodynamics and marine structures and he is responsible for the development and technical output of the company in these areas.  He has also carried out a considerable body of work in the area of seakeeping and vessel dynamics and is one of the company’s specialists in this field.  He has advised clients on a number of important legal cases and given evidence in the Scottish High Court, Oslo City court and many times in arbitration under various jurisdictions.
