Strength Analysis Of Ship For Navigation In Ice

Different from the regular ships, an ice ship (including icebreaker) is the ship which can independently sail or be helped by icebreakers. Considering the specificity of sailing in the ice area, design of ice ships needs to consider much, such as icebreaker head design, greater coordination of structure of ice zones, use of special steel, propulsion systems and special cold proof of other equipments and so on.Generally, all that include the situation of ice zone are called ice ships. Throughout the world the ice ship is one of common ships. According to the different ice zones, the hull structure should be strengthened by different standards. Therefore, ice ships not only meet the general requirements, but also the strength of ice levels.With global warming, the Arctic routes opened. Driven by the huge economic benefits, the ice ship is developing very fast. On the north coast of our country especially in Bohai Bay, light or heavy ices will appear in every winter, which seriously affect the normal operation of regular ships. Therefore, corresponding ice strength should be used in the ship sailing in the northern area of china.In recent years, most researchers calculate the structure strength of ice zones based on the standard and formulas, while study on the direct effect stay break between the ship and the floating ice is rare.In fact, ice level of some years in northern China is close to B3level, the standard requirements of ship strengthen class is B. This paper makes a brief analysis about B strengthened ships and whether normal navigation in B3and ice conditions. This paper takes100,000ton tankers for example, sets up the finite element model, and analyzes the structure strength of ships according to the relevant of "level specification of steel ships"and gets the ice ship structure strength as a reference.
