Embodiment Construction

[0049]Next, a ship according to one embodiment of the present invention will be described based on the drawings.

[0050] figure 1 It is a side view which shows the overall structure of the ship which concerns on embodiment of this invention. figure 2 yes figure 1 A close-up view of the ship's bow.

[0051] The ship 1 of this embodiment is a ship with a relatively fast Froude number (Froude number) of about 0.25 to 0.38. The ship 1 is, for example, a passenger ship, a ferry ship capable of carrying vehicles, a passenger ship capable of carrying cargo, a RORO ship (Roll-on / Roll-off ship: roll-on-roll-off ship), a container ship, and a dry cargo ship such as a car carrier. "Passenger ship" may also include a "survey ship" conducting oceanographic surveys. Passenger ships and cargo ships are classified as relatively thin ships with a square coefficient Cb of 0.6 or less.

[0052] Such as figure 1 As shown, the hull 2 ​​of the ship 1 is provided with a propeller 5 and a rud...

Abstract

A ship (1) has a Froude number of 0.25 to 0.38 and is provided with: a bow bulb (7) that is disposed below the full load waterline and of which an upper end portion is disposed on the lightest load waterline or thereabove; and a stem (8) that has a front edge portion (8a) that extends vertically upward from a front end portion (7a) of the bow bulb (7).

Description

technical field [0001] The present invention relates to ships. [0002] this application claims priority based on Japanese Patent Application No. 2015-004521 for which it applied to Japan on January 13, 2015, and uses the content here. Background technique [0003] In order to improve the propulsion performance of a ship, there are methods of reducing hull resistance and methods of improving propulsion efficiency. In particular, the reduction of hull resistance greatly contributes to the improvement of propulsion performance. [0004] The total resistance of a ship can be roughly classified into two resistance components: frictional resistance and residual resistance. In addition, residual resistance can be classified into wave resistance and viscous resistance. For reduction of wave resistance, there is known a technique of improving bow shape. [0005] As a bow shape for reducing the above-mentioned wave-making resistance, a bulbous bow is mentioned, for example. The ...
