Ship bow structure and design method thereof

Abstract

The invention discloses a bow structure of a ship and a design method thereof, comprising a chain locker body arranged on the bow of the ship, the chain locker body having a cavity for storing anchor chains, and the chain locker body The transverse side walls are connected to the hull plating through the structural connection walls of the vessel. The structural connecting wall through which the lateral side wall passes is connected to the outer plating of the hull, and the supporting structure at the bottom of the chain locker body is replaced by the structural connecting wall. The gravity of the anchor chain is effectively transmitted to the outer plating of the hull through the shear stress of the structural connecting wall. Therefore, there is no need to set additional supporting structures on the bottom plate of the hull for supporting the anchor chain and strengthening the chain locker, and the structural connection wall on the outer plate of the hull is rationally used to save the manufacturing materials of the bow structure of the ship and improve the installation efficiency. At the same time, it also prevents the support structure from occupying the space at the bow of the ship, and frees up space for the installation of marine equipment installed at the bow of the ship.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to a ship bow structure and a design method for the ship bow. Background technique [0002] Existing merchant ships generally set the chain locker for storing anchor chains at the bow of the ship, and the chain locker usually extends downward from the deck of the ship to the ballast water tank or empty space at the bow of the ship. Since the depth of the chain locker is generally half of the ship's molded depth, the bottom of the chain locker will not be located at the bottom of the ship, but above the bottom of the ship, and the anchor chain in the chain locker is heavy, so it needs to be placed in the ballast water The support structure provided in the tank or void to support the transverse bulkhead or longitudinal side wall of the chain locker. The method of supporting the chain locker by setting the support structure has the following disadvantages: 1. The setting of the support ...

AI Technical Summary

Problems solved by technology

The method of supporting the chain locker by setting the support structure has the following disadvantages: 1. The setting of the support structure increases the weight of the ship structure, increases the workload in shipbuilding and construction, and increases the cost of materials such as paint and steel; 2. Due to the support structure The existence of the ship will affect the division of ballast tanks or empty cabins at the bow of the ship, increase the difficulty of arranging marine equipment such as bow depth sounder equipment and side thrusters, and is not conducive to the maintenance of subsequent marine equipment
