Personal profile

Personal Statement

Sandy Day is Professor of Marine Hydrodynamics in the Naval Architecture Ocean and Marine Engineering Dept. at Strathclyde University, and is the Director of the University’s Kelvin Hydrodynamics Laboratory. His research interests lie in computational and experimental hydrodynamics; he is actively engaged in fundamental and industry-focussed research on energy efficiency of ships, motions and loads on ships and offshore oil and gas structures, and performance of offshore renewable energy devices, as well as sports hydrodynamics applied to sailing rowing and kayaking.

He is highly active in the International Towing Tank Conference (ITTC), which sets best-practice standards for large-scale hydrodynamics facilities worldwide; he has recently chaired the ITTC committee on Hydrodynamic Testing of Marine Renewable Energy Devices, and was responsible for writing new best-practice standards for tank testing of offshore wind, wave and tidal energy devices.
