What is the speed of this ship?
The speed of large container ships is 20-28 knots, that is, 36-52 km/h.
The maximum speed of a large nuclear-powered aircraft carrier can reach 32-35 knots, which is 60-65 km/h.
The speed of ordinary warships is between 20-30 knots, that is, 36-55 km/h.
The speed of a large cruise ship is similar to that of a large container, and 1 knot is 1 nautical mile per hour, 1 nautical mile =1.8km..
Extended data:
Ship speed refers to the distance the ship travels relative to the seabed in unit time. It affects the shipping cycle, shipping operation cost and shipping competitiveness, and is an important technical performance of transport ships.
Ship speed classification:
1, rated ship speed
When the rated power, rated speed and water depth are sufficient, the speed that a ship can reach in still water is called rated ship speed, also called delivery speed, which is the highest ship speed.
2. Ship speed at sea
In order to ensure the safety of the main engine, an appropriate power reserve of the main engine must be reserved. Therefore, when the main engine actually sails at sea, it is usually 90% rated power, and the corresponding main engine speed is 96% ~ 97% rated speed.
The speed of the ship at this time is called the speed of the ship at sea. Ship speed at sea can be divided into full load and no load (ballast) ship speed. With the wear and tear of the main engine and the aging of the hull, the ship speed will decrease.
