Description

Arctic and Antarctic areas are getting more and more attractive for cruises. The vessel designed for the operations in these and other ice areas like Canada and Baltic Sea must sail in ice in a safe and efficient way, as far as possible, without support of ice breakers. At the same time they should be quite efficient also in open waters. However the hull hydrodynamic shape of an efficient vessel designed for the open sea operation is normally not suitable to operate in ice, while a vessel optimized for proper sailing in ice normally suffers from strong penalties when sailing in free waters. This paper deals with the development of new patented devices applied to the bulb and to the stern of the ship which can provide at the same time excellent performances in ice breaking without any detriment when the ship is operated outside ice seas. The new devices are called ICE SABRE, applied to the bulb and ICE MIRROR installed on the stern transom. A comprehensive ice model testing description of two devices shall be given including tests in pack ice, brash ice and manoeuvre against ice ridges.
