Anchor Chain Machine

Its primary purpose is to provide a mechanism for ships and boats to hold their position either during berthing and mooring operations at ports, or for large offshore installations such as semi-submersible oil rigs to remain stationary above an oil deposit. The anchor rode (or "cable" or "warp") that connects the anchor to the vessel will usually be made up of chain, rope, or a combination of those. Large ships will use only chain rode.
