The turning motion of a ship in ice is resisted mostly by ice forces acting upon the hull. A ship in turn experiences an asymmetrical ice force distribution in the bow region and ice forces also along the ship side. Together with the hydrodynamic effects on the hull, these ice forces cause a resisting moment which counteracts the active turning moment of the rudder. The experimental investigation is carried out using free running ship models with systematically varied hull shape. Model tests with four different hulls are described in the report. However, complementary tests should be conducted in order to obtain a complete survey of the influence of the hull shape on the turning performance.
