A design method of a grain-type sawdust ship with good safety

Abstract

The invention relates to the technical field of ship design, in particular to a design method for a wood dust ship capable of compatibly loading grains and having good safety. The design method comprises the following steps of cabin design, strength design, cabin classified design, safe heeling moment calculation, the amount matching of two categories of cabins, the reinforced design of a ship body and the like in sequence. On a premise that the ship guarantees to be safe, the grain compatible loading capability of the wood dust ship can be greatly improved.

Description

technical field [0001] The invention relates to the technical field of ship design, in particular to a design method of a grain-type sawdust ship with good safety. Background technique [0002] A wood chip ship is a special vessel specially used for loading wood chips, and is generally limited to the loading of wood chips. As wood chips are a kind of light cargo, their density is relatively small, about 0.5t / m3, so in order to realize the full loading of wood chips, the cargo hold of the wood chip ship is designed with a relatively large capacity. [0003] In the prior art, since the wood chip ship is designed according to the loading of wood chips in the design stage, it cannot be well compatible with the loading of other goods. For example, chip carriers may sometimes be used for grain loading in order to increase their utilization. However, as a kind of liquid cargo, the grain will sway laterally with the ship during the voyage, and the lateral offset will occur in the ...

AI Technical Summary

Problems solved by technology

However, as a kind of liquid cargo, the grain will sway laterally with the ship during the voyage, and the lateral offset will occur in the cargo hold. After the grain is offset in the hold, a large lateral moment will be generated. , which will further increase the roll angle of the ship, and even cause the ship to capsize

Moreover, for wood chip ships, since the density of grain is much higher than that of wood chips, generally above 0.7t / m3, if it is used to load grain, the cargo hold generally cannot be fully loaded, which will cause excessive grain heeling moment, which may cause the ship to lose weight. In the event of overturning, if only part of the cargo hold is loaded with grain, the overall longitudinal strength generally cannot meet the full load requirements.
