The term 'Harbor Platform' is a collective term for two structures commonly found in harbors: wharfs and piers. A WHARF is a structure built along the shoreline of a harbor, river, or other body of water, and is used to provide access to ships and boats. A PIER is a raised platform built over water, usually supported by piles or pillars, and is used for docking, loading, and unloading vessels. Both wharfs and piers are important components of a harbor platform, providing a safe and secure area for vessels to dock and unload cargo.
