Hydrodynamic Effect of Restricted Waters on Ships

Hydrodynamic Effect of Restricted Waters on Ships

Mr Momchil Terziev, a PhD researcher at the Department of Naval Architecture, Ocean and Marine Engineering at the University of Strathclyde is using Computational Fluid Dynamics to research shallow water effects on ships. When a ship is in close proximity to the seabed, the occurring hydrodynamic phenomena are not well understood. Among these is a notable increase in resistance, and the combined effect of sinkage and trim, known as ship squat, which is consistently one of the main causes of incidents according to the European Maritime Safety Agency. The project’s goal is to broaden the understanding into the mechanisms by which ship squat and resistance are coupled, as well as their overall phenomenology. This is done by identifying the optimum numerical set-up and potential scale effects, not accounted for during experimental tests. The approach adopted involves first re-creating simple cases in deep water, before conducting studies in shallow water. Due to the volume of required simulations and computational load per simulation, the high performance facilities at the University are an integral part of this research.
