Ship Design for Ice

Abstract

Abstract Ship design for ice includes many factors that must be taken into account, compared to open‐water vessels. The starting points are the environmental and ice conditions and also operation profile of the vessel. To reach adequate ice performance, main dimensions, hull form, propulsion type, machinery, and power must be selected and designed based on rules, design studies, numerical analysis, and model tests. Suitable ice‐strengthening level must also be selected. Because good ice‐going capabilities often add open‐water power requirement, a compromise between different requirements must be found based on technical and economic studies for a single vessel or whole fleet in a transport system. All these factors have been described in this article for different types of ice‐going vessels designed for different operation areas.
