What is the knowledge of ships and navigation, what are the knowledge of ships?

1.Under what circumstances does a ship use heavy and light oil?

Light oil is used in the case of sailing and start-up, preparation of the heat engine, as well as harsh sailing conditions, special working conditions of the main engine.

Heavy fuel oil is used when the navigation is stable and the main engine is in normal working condition (70%-85% power).

2.If the latitude deviates by one degree, one minute, or one second, how many nautical miles or kilometers does the actual deviation be?

Yes, it needs to be calculated.

3.In the indication of the direction of the wind "ely"and ""nly"What to represent.

I don't know if you are in English, E is the abbreviation of East, and N is the abbreviation of North.

4.Speed conversion? Isn't the speed of the talk expressed in terms of "knots"? So how many miles per hour does that translate to?

Yes, help you baidu! Remember to ask later.

1 nautical mile km.

1852 meters.

1 knot 1 nautical mile hour.

kilometers per hour.

5.When is cylinder oil consumed?

The high-viscosity lubricating oil, which is mainly used to lubricate the cylinders of steam engines, should be used to lubricate during navigation, and you should add butter to your bicycle.

6.What is the purpose of freshwater stocks?

The role is great, the crew eats and washes clothes and bathes on the ship, these are small fresh water consumption, and some main engines rely on fresh water to cool down the large consumption.

The knowledge about the ship has:

1. The bottom of the ship has a single bottom and a double bottom structure, which is composed of the outer plate of the bottom (including the flat keel), the inner bottom plate and the inner bottom side plate (the ship with a double bottom structure), the longitudinal skeleton, the transverse skeleton and other components. There are two types of bottom skeletons: transverse skeleton type and longitudinal skeleton type.

2. In order to strengthen the head and tail structure of the hull, there is a head post at the head end, and a tail post is set at the tail end. There are several bulkheads inside the hull to form cabins for different purposes.

3. The bow and stern of the ship are equipped with anti-collision bulkheads, which form the head and tail cabins respectively to ensure safety. The engine room where the main engine, auxiliary engine and its ancillary equipment are installed is generally located in the middle or stern of the ship, and the corresponding ship type is called the medium or stern type.

4. The bridge building is the center of the work and life of the whole ship, the top floor is the bridge, chart room, telegraph room, etc., and the part below the bridge is the place where the crew lives, rests and entertains. In order to obtain more usable and living space, the three floors can be connected separately or completely.

5. The power plant includes the main engine that provides propulsion power for the ship, the generator set that provides power and lighting for the whole ship, and various other auxiliary equipment and equipment.

The knowledge of ships is that boats, also known as ships, ships, and boats, were developed with the development of human beings. According to the material, the ship can be divided into steel ship, wooden ship, alloy Danhui ship, FRP ship, etc.

Boats use the buoyancy of water and rely on manpower, sails, engines, etc. A boat is a transportation tool that can move on water.

Ships played an important role in geographical exploration and the development of science and technology, such as Zheng and the use of boats to spread compasses and gunpowder to other regions.

Boats can be divided into human-powered boats, sailboats, sailboats, ships, and barges according to power, and can be divided into monohulls, multihulls, hydrofoils, and hovercraft according to their structure.

A boat can float on the surface of the water because the water is buoyant, the volume or amount of water that the boat pushes away to allow it to suspend or float on the surface.
