Abstract

The invention provides a bow structure of a polar transport ship. The angle A between the mid-longitudinal section line of the bow and the design waterline is 28.5° to 31.5°, and the bow is at one quarter of the ship's width. The design waterline tangential angle B is 36.5°~37.5°; the length of the design waterline is L; the water entry angles a, b, c, d are 55.0°~58.5°, 40.3°~43.5°, 36.0° °~39.0°, 36.33°~34.5°; waterline angles e, f, g, h are respectively 41.5°~42.0°, 27.5°~28.0°, 24.0°~25.0°, 20.0°~21.0°; The horizontal distance l between the lowest point of the bottom of the bow and the bow of the bow is 20% to 25% of the length of the polar transport ship. The bow structure provided by the present invention can greatly reduce the resistance of crushed ice and open water, and reduce the discharge.

Description

technical field [0001] The invention relates to the technical field of polar ship hull line design, in particular to a bow structure of a polar transport ship. Background technique [0002] As the density of the ice area in the Arctic gradually decreases every year, when polar transport ships sail on the Northeast route in spring and autumn, less than 96% of the ice is ice below 1.5m, and the operating volume of the Northeast route will increase. The EEDI standard and the protection of the Arctic Circle and the consideration of the economy of the ship, the total resistance of the ship when sailing on the Northeast route is worth considering. The ship type design is the key to the overall design of the polar ship. The main purposes of the polar transport type ship type design are: suitable The selection of the captain of the ship, the influence of the change of bow and stern form on the ice resistance; the selection of the above values ​​is mainly to solve the ice resistance ...
