What equipment is typically used to secure a ship’s mooring line on a pier?

A bollard is a sturdy, vertical post typically made of metal or concrete that is installed on a pier or dock. It is specifically designed to secure a ship's mooring lines effectively. When a vessel docks, the crew ties the ship's lines around the bollard, which holds the ship in position against wind and current forces. The design of a bollard allows for multiple lines to be secured, ensuring stable mooring for various sizes of vessels.

In contrast, while a cleat is also used for securing lines, it is not as robust as a bollard and may not provide the same level of security in rough conditions. A windlass is a mechanical device used for raising and lowering anchors rather than securing mooring lines, and a winch is generally used for moving heavy objects or controlling tension rather than directly securing a ship’s mooring. Hence, the bollard is the most suitable and effective equipment for this purpose.
