Anchor is the main mooring equipment of the ship, which is connected with the ship through anchor chain. Throwing the anchor under the water can stop the ship.

The anchor is mainly composed of an anchor claw, an anchor crown and an anchor handle, wherein the anchor handle is connected with an anchor chain through a shackle, and is connected with the anchor crown and the anchor claw through a pin shaft, and can rotate relatively within a limited range; The top of the fluke is designed with an acute angle to improve the soil grasping performance of the fluke (Figure 1).

In navigation technology, there are many mature technologies and skills about anchor operation. However, in the design and inspection of ships, there are still doubts about the technical requirements of anchors in the industry, and a systematic analysis is needed.

Anchor is the main part of mooring equipment. The iron boat stop is connected to the boat with a chain, and the anchor can be thrown into the bottom of the water to stop the boat. The ancient anchor is a big stone or a basket full of stones, which is called "anchorage". The anchor stone is tied with rope and sank to the bottom of the water, and the ship is anchored according to its weight. Later, there was a wooden claw stone anchor, that is, wooden claws were tied to both sides of the stone to anchor the ship by weight and grip.

The iron ship stop is connected to the ship with a chain, which can throw the anchor to the bottom of the water to stop the ship. The technical requirements for anchors in the ship code are aimed at mooring equipment temporarily moored in ports or sheltered areas due to waiting for berthing, tides and other reasons. Although anchors have many uses in ship operations and engineering operations, unconventional uses do not fall within the scope of the Code.
