How many waves and strong winds can a warship with large displacement withstand? What is the scientific basis?
Can a warship with large displacement withstand such violent wind and waves? Strictly speaking, no.
No warship or warship, including the so-called large displacement (large tonnage), can compete with this natural force. Typhoon and hurricane only have different names and paths in the sea area, but their destructive power is very powerful, especially the wave peaks and valleys within 300 nautical miles around the eye of typhoon, which are the bane of any large-scale (large tonnage and large displacement) warships and ships. This sea area is not a question of how much waves and strong winds it can resist. The larger the tonnage, the greater the displacement, and the easier it is for warships and ships to break their shells. The forces of wave peaks and valleys make the hull sag and shear.
If it is a ship with heavy load or low freeboard, a large amount of seawater will flood into the ship's side in wave after wave. These thousands or even tens of thousands of tons of weight thrust will change the proper swing period and recovery torque of the ship, which will make it unable to recover quickly and will probably capsize the ship.
In the 1920s, when the Japanese naval joint fleet was training at sea, it was still attacked by a typhoon because of the measures of avoiding Taiwan and anchoring. The whole fleet suffered heavy losses in the battle, and many ships collided and sank into the sea because of anchoring, just on the edge of the typhoon.
In the late period of the Pacific War, US naval formations were also hit by typhoons in the Philippine waters, and nearly half of the large and small ships were lost. This typhoon has just formed and its power is not very strong. The damaged ship may be related to the quality of rapid construction during the special period of war.
Then, how to prevent unexpected catastrophic accidents of ships in bad weather at sea has little to do with the ship's structure, ship type, displacement and tonnage.
We all know that water can carry a boat and also overturn it. Man can conquer nature. It's not easy to use here. We can only trust science. The current ocean weather forecast is that small fishing boats can receive it in real time, and advanced ocean-going ships. Take the most harmful typhoon as an example. Every day, sailing ships can receive more than a dozen meteorological waves, sea state forecasts, typhoon conditions, ranges, moving paths and analysis charts, with an interval of 4? Six hours. The ship can receive the weather in front of the berth path through the satellite, and judge whether the typhoon moving path has an impact on the ship and whether it is necessary to take corresponding typhoon avoidance measures.
If 12 hours will be affected by the typhoon, and the typhoon is on the ship's path, small and medium-sized ships should choose to anchor to avoid the typhoon. For large or super-large ships that are inconvenient to anchor, you can choose to detour, or speed up to catch up with the typhoon, or slow down and wait for the typhoon to continue.
All ships have a wind resistance rating standard, which is scientifically calculated. As long as it does not exceed the upper limit of this standard, the ship should be fine. But don't forget, the actual height of the wind and waves at sea may be much higher than the value of the weather forecast, and it is terrible for a person to think about it on board.
