The anchor chain is also known as anchor cable, which is a heavy chain used for holding a vessel at anchor. As there are no brakes on the ship for the simple reason that, the ship is floating on water. Therefore, when the ship is stopped and its engines are not running, there needs to be a mechanism to ensure that the ship does not drift freely in the sea. The tool for holding the ship in place is the ship anchor chain. Normally, the chains are made of marine steel or stainless steel with hot-dip galvanized treatment or black paint.
