Icebreaker

Abstract

The invention discloses an icebreaker. One end of a ship prow is provided with three characteristic positions including the first position, the second position and the third position. The first position is located at the 45%-55% of the width of the icebreaker. The second position is located at the 70%-80% of the width of the icebreaker. The third position is located at the 90%-95% of the width ofthe icebreaker. A bulbous bow is arranged on the ship prow. The half entrance angle in the first position is smaller than 30 degrees. The half entrance angle in the second position is smaller than 20degrees. The horizontal distance between the third position and the ship prow is greater than 40 meters. According to the icebreaker provided by the invention, by arranging the bulbous bow on the shipprow and designing the corresponding ship prow specification facilitating icebreaking, the ship prow is made to have the icebreaking capability; and in addition, a series of icebreaking structures are designed on a ship stern portion as well, the ship stern portion is made to have the icebreaking capability as well on the premise that the ship prow of the icebreaker has the icebreaking capability, the icebreaker meets arctic navigation requirements conveniently and can adapt to different navigation demands, and the economical efficiency and the versatility of the icebreaker are improved.

Description

technical field [0001] The invention relates to the field of shipbuilding, in particular to an icebreaker. Background technique [0002] As the global climate warms and seawater melts, resources and shipping lanes have changed from potential interests to real interests. Judging from the current trend, the global shipping lanes are gradually shifting their focus to the Arctic shipping lanes. People pay attention to the Arctic sea route. On the one hand, most of the developed countries in the world are located north of 30 degrees north latitude. This zone produces 80% of the world's industrial products and accounts for 70% of international trade. The smooth opening of the Arctic shipping lanes will shorten the voyage of international trade routes in these regions by about 6,000-8,000 kilometers, save 40% of shipping costs, and thus bring huge economic benefits. On the other hand, once the Arctic waterway is opened, it can also reduce the increasingly serious congestion in th...
