Problems solved by technology
Since the diameter width of the inspection channel is required to be at least 600mm, the design method of the existing technology requires that the width of the corresponding hull structure at this part is at least 600mm, and the structure in this method will cause the size redundancy of the structural parts at this part Larger, resulting in a waste of materials, increasing the manufacturing cost of the ship, and due to the increase in the size of the hull structural parts, it will lead to a decrease in the load capacity of the ship, and at the same time, it will also have a certain impact on the speed of the ship

The invention discloses a method for manufacturing and installing a ship inspection channel, which comprises the following steps: step S10, calculating the ship hull longitudinal strength according tothe bending strength and the shear strength of the ship hull beam, and reducing the size of the inspection channel installation structure on the ship; step S20, providing an aluminum alloy plate, andmaking that aluminum alloy plate into an inspection channel structure to reinforce the overall longitudinal strength of the ship hull by using the aluminum alloy plate; Step S30, connecting the inspection channel structure with the inspection channel mounting structure on the ship through the connecting part. The invention can improve the strength of the inspection channel, save the manufacturingmaterial, reduce the weight of the empty ship and reduce the influence on the speed of the ship.
Description
technical field [0001] The invention relates to the field of ships, in particular to a method for manufacturing and installing a ship inspection channel. Background technique [0002] Generally, when designing an oil tanker, it is necessary to design the inspection channel of the ship according to the specifications. The inspection channel is mainly used for maintenance personnel to walk to regularly inspect the structure of important parts of the ship, so that structural damage can be found and repaired in time. In the prior art, the inspection channel is usually designed as a part of the hull structure. Since the diameter width of the inspection channel is required to be at least 600mm, the design method of the existing technology requires that the width of the corresponding hull structure at this part is at least 600mm, and the structure in this method will cause the size redundancy of the structural parts at this part Larger, resulting in a waste of materials, increasin...
