Embodiment approach

[0034] In further embodiments of the present invention, please continue to refer to Figure 1 to Figure 4 As shown, the length of the ship is 115m, the width of the ship is 27.8m, and the length of the bulbous bow 2 is preferably 2.4% of the length of the ship,

[0035] In further embodiments of the present invention, see figure 1 As shown, from the perspective of the side shape, the upper surface of the bulbous bow 2 is specially designed, preferably with a downward slope of 30 degrees, so that the setting of the bulbous bow 2 will not affect the connection, disassembly and locking of the bow equipment. and other operations are affected.

[0036] In further embodiments of the present invention, see figure 2 As shown, the ratio of the cross-sectional area of ​​the bulbous bow 2 at the bow vertical line to the cross-sectional area of ​​the midship below the waterline is preferably 0.11.

[0037] In further embodiments of the present invention, see Figure 4 As shown, a bow...

Abstract

The invention discloses a self-propulsion cutter suction dredger with a bulbous bow. The bulbous bow is arranged on a bow of a hull of the self-propulsion cutter suction dredger. A side thruster cabinis arranged in a bulbous bow area. A bow thruster is arranged inside the side thruster cabin. The side thruster cabin is arranged in the space between a bow anti-collision wall and a bulbous bow outer plate. The length of the bulbous bow is 1.5%-3.5% of the length of the hull. The bulbous bow area ratio of the bulbous bow is 0.1-0.25. Through the additionally-arranged bulbous bow and the bow lineoptimizing scheme, transition of the bow molded line is facilitated, and the inflow angle on the designed waterline of a large bow column in the prior art is decreased. Meanwhile, a head wave can beshifted forward, favorable interference is generated, accordingly the wave-making resistance and the total resistance of the dredger are reduced, and high-speed performance is improved. The arrangement space for the bow is enlarged, accordingly the scheme that the side thruster is arranged in the bow can be achieved, and the maneuverability of the dredger is improved.

Description

technical field [0001] The invention relates to the technical field of a self-propelled cutter-suction dredger, in particular to a self-propelled cutter-suction dredger with a bulbous bow. Background technique [0002] Self-propelled cutter suction dredgers belong to engineering ships. Considering the requirements of equipment layout and operation stability, a larger ship width is often selected, resulting in a fuller line at the bow and a larger inflow angle, which is not good for rapid performance. . [0003] In addition, due to the operation mode of the cutter suction dredger, the bow area needs to be grooved. This leads to tight space at the bow of the ship, making it difficult to arrange side thrusters, which affects the maneuverability of the ship. [0004] All self-propelled cutter suction dredgers have the above problems at present. [0005] Therefore, those skilled in the art are devoting themselves to developing a new type of ship that can improve the speed and ...
