It is shaped to snap into the subsoil when thrown into the water to provide grip. Special equipment for keeping ships or other floating systems in predetermined waters by means of a chain or cable attached to the top.

Anchor in the shape of a special, usually made from forged steel or cast steel, and it consists of an bar and body. The body by the ring (or shackle), dry anchor (shank), arm, a fluke.

Anchors on the ship shall be selected based on the number of habitat devices specified in the specification, or calculated based on the ship displacement, water wind area, attachment resistance, anchoring depth and chain length.
