Marine Anchor Chain


Why are the lengths of anchor chains used on the left and right sides of the ship different .

Our ship is equipped with 25 units of ship anchor chains, with 13 knots on the port side and 12 knots on the starboard side. Can anyone explain why the left and right sides are different?


2. Check the outfitting manual to meet the number of outfitting requirements. Equip according to actual needs for odd numbers. It doesn't necessarily mean there are more sections left than right or vice versa.

3. There are no special requirements. According to the design requirements. Generally, there are 11 sections on the left and 13 sections on the right.

4. Add one more anchor root.

5. An additional 27.5-meter ship anchor chain is required according to regulations, and specific reasons need to be explained.

6. Isn't this a standard requirement? Some sections have the same number, while others have different numbers. The specific calculation is based on the number of outfitting components during the design phase.

7. I didn't see any regulations stating that it is acceptable for the starboard side to be longer than the port side (according to the outfitting chart, selecting odd numbers means one longer and one shorter, and even numbers means the same length).

When the number of anchor chains used on the ship is odd, it is stipulated that the left side should have one more section than the starboard side.

But if you install an extra section on the starboard side than on the port side, it doesn't matter, the classification society can also accept it.
