Low transverse metacentric height and high speed are peculiar destabilizing factors in ship manoeuverability according to the attainable large heeling angles. The phenomenon indeed occurs in the case of vessels characterized by loading conditions with low transverse stability – e.g. high centre of mass of container vessels and ROROs: starting from Kijima’s single screw container vessel evidence, an extension of the study to twin-screw ferry vessels is undertaken, with the scope of quantifying its effect in terms of turning and ziz-zag IMO margins at an early design stage.

Abstract
Low transverse metacentric height and high speed are peculiar destabilizing factors in ship manoeuverability according to the attainable large heeling angles. The phenomenon indeed occurs in the case of vessels characterized by loading conditions with low transverse stability – e.g. high centre of mass of container vessels and ROROs: starting from Kijima’s single screw container vessel evidence, an extension of the study to twin-screw ferry vessels is undertaken, with the scope of quantifying its effect in terms of turning and ziz-zag IMO margins at an early design stage.File in questo prodotto:
