Method for preventing half ship from floating in dock

Abstract

The invention discloses a method for preventing a half ship from floating in a dock. The method comprises the following steps that S1, the weight and the position of the center of gravity of the halfship are calculated, and the liquid level height in the dock when a whole ship is undocked is determined; S2, a cabin which needs to be waterlogged in the half ship is determined according to the weight of the half ship, the position of the center of gravity of the half ship, the height position of the half ship and the liquid level height; S3, water inlet holes are formed in the cabin which needsto be waterlogged, so that the interior of the cabin which needs to be waterlogged communicates with the exterior of the half ship, and the heights of the water inlet holes are lower than the liquidlevel height; and S4, water is fed to the dock, and the liquid level height is reached. According to the method for preventing the half ship from floating in the dock, it can be guaranteed that the half ship which does not complete carrying is always in the state of not floating in the case of feeding water into the dock, and half ship overturning and structural damage caused by floating of the half ship are avoided.

Description

technical field [0001] The invention relates to a method for preventing half-ships from floating in a dock. Background technique [0002] During the construction of ultra-large container ships, in order to improve the utilization rate of the dock, half-ships and whole ships of different ships are often carried in the dock at the same time. After the whole ship is loaded, the dock needs to be filled with water to make the whole ship out of the dock. At the same time, the half ship must also bear the buoyancy brought by the water entering the dock. The combined force of the buoyancy and the gravity of the hull itself can easily cause the half ship to capsize or damage the local structure. [0003] In the traditional method, it is necessary to ensure the loading state of the general section and the subsections during the loading process of the half-ship, and cooperate with ballast tanks or weights. At the same time, the depth of the dock when floating is considered, and the dra...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to overcome the defects in the prior art that the floating of the half-ship in the dock may easily cause the half-ship to capsize or damage the local structure when the whole ship is out of the dock, and to provide a method to prevent the half-ship in the dock from lifting when the whole ship is out of the dock. floating method
