What is the length of the ship's anchor chain?

Because regardless of your draft, the length of the ship's anchor chain must be able to reach the bottom of the water in order to anchor. If the length of your ship's anchor chain is too short, it will not be able to anchor and complete the berthing.

Moreover, during the process of stopping, the engine of the ship is usually turned off. Once anchor failure occurs, it takes a lot of time to restart the ship, and there is simply no time to control it. Extremely prone to safety accidents such as ship collisions.

So the length of a ship's anchor chain usually needs to be long enough.

So how to calculate the length of a ship's anchor chain?

The unit of length for anchor chains on board is "knot";, Usually, it is stipulated that the length of the anchor chain is 27.5 meters per section

2. The usage mark of Chinese warships is based on a distance of 20 meters per section.

3. (Subtract the diameter of a circle from one section of anchor chain) Multiply by the number of sections plus the diameter of a circle

4. The length of the anchor chain is measured in "sections". In China, the standard length of each section of the anchor chain is 27.5m, while in British countries, it is often measured as 15 knots, which is equivalent to a meter constraint of 27.5m. There are also sections of 25m and 20m.

5. Under normal circumstances, the length of the anchor chain is 2.5 times the water depth h, that is, L=2.5 hours,

Anchors, the necessary things do not want to be human power, they are often anchor machines, but even the strongest anchor machine can bear the corresponding total weight.

When the anchor chain is too thick and heavy, it is highly likely that it cannot be pulled up. Another thing is that if the anchor chain is too long, when it is put away, the stern of the ship may hook up with large and medium-sized rocks or some disorderly things under the sea. If it gets stuck, it is highly likely that it cannot be pulled up, so the ship has to choose to abandon the stern. And its market value is very high and expensive, which can lead to a lot of property losses. Therefore, the docking point of the ship is also selected in shallow water areas, and from the far sail to the deep sea, the vast majority do not want to choose to stop still.
