The Research Project

Global demand for fast and efficient sea transportation has led to the evolution of large high-speed and lightweight vessels for both commercial and military use. Different types of high-speed craft have been designed to satisfy this requirement, but some factors such as large deck area, relatively large deadweight to displacement ratios, the ability to provide lightweight Ro-Ro vessels (Roll-on/Roll-off vessels capable of carrying wheeled cargo such as cars and trucks) and high hydrostatic and hydrodynamic stability have proven catamarans to be particularly popular.

High-speed catamarans, due to their slender twin hull geometry and high operating Froude number, frequently experience larger heave and pitch motions and accelerations than those of conventional monohulls operating at lower Froude number. The vessel motions are directly influenced by increases in the operating speed, leading to passenger discomfort and potential structural damage when operating in higher sea states and severe sea conditions. A motion control system is therefore required to reduce these large motions, increase passenger comfort and improve the vessel performance.

There have been some prior studies of Ride Control Systems (RCS) relevant to this type of fast ships. The current project aims to continue the study of RCS and the influence of ride control algorithms on the motion and load response of high-speed catamarans by numerical and experimental investigations using an existing 2.5m hydroelastic segmented catamaran model based on an Incat 112m wave-piercer catamaran.
