Differences in the Influence on Different Parts of the Ship

 

Ship's Bottom: The ship's bottom is a crucial part of the ship's structural weight. As the ship's bottom needs to bear huge pressure, the thickness of the shipbuilding steel plates is often relatively thick. If the thickness of the shipbuilding steel plates at the ship's bottom increases, for example, from 20mm to 25mm, for a large - scale bulk carrier (assuming the area of the ship's bottom is 1000 square meters), the weight of the ship's bottom part will increase by approximately 39,250kg ((25 - 20)×7.85×1000). This will not only increase the self - weight of the ship but also affect the ship's deadweight and navigation performance.

 

Ship's Sides and Deck: Changes in the thickness of the shipbuilding steel plates of the ship's sides and deck will also have a noticeable impact on the weight of the ship structure. For example, on the deck of a container ship, if the thickness of the shipbuilding steel plates increases from 16mm to 20mm, for a deck with an area of 2000 square meters, the weight will increase by approximately 62,800kg ((20 - 16)×7.85×2000). An increase in the thickness of the ship's sides will also increase the weight of the ship's sides, which may lead to a change in the position of the ship's center of gravity and thus affect the ship's stability.

Calculation of Comprehensive Weight Change

 

When the thickness and width of the shipbuilding steel plates change simultaneously, the change in the weight of the ship structure needs to consider the influence of both. For example, if the thickness of the shipbuilding steel plates increases from 12mm to 15mm and the width increases from 2 meters to 3 meters, for a shipbuilding steel plate with a length of 10 meters, the original weight is 12×0.001×2×7.85×10 = 188.4kg, and the changed weight is 15×0.001×3×7.85×10 = 353.25kg, with an increase in weight of 164.85kg.

 

Optimization Strategies

 

In ship design, in order to control the weight of the ship structure, it is necessary to reasonably select the thickness and width of the shipbuilding steel plates under the premise of ensuring the ship's strength, safety and other performance requirements. Through optimizing the ship structure design and using methods such as finite - element analysis, the stress conditions of the shipbuilding steel plates in different parts can be accurately calculated, so as to determine the most suitable combination of thickness and width. For example, in some parts where the strength requirements are not extremely high, the thickness and width of the shipbuilding steel plates can be appropriately reduced; while in key stress - bearing parts, sufficient thickness and width should be ensured to guarantee the safety of the ship. At the same time, new - type high - strength and low - density materials can also be considered to reduce the weight of the ship structure.
