  • TERMS RELATED TO DOCKS AND HARBORS
  •  Apron: The open space left immediately in front of a berth of a ship is known as apron.  Approach channel: The dredged clear channel through which ships proceed from the open sea to the harbour basin is known as approach channel.  Barges: The vessels which require less depth of water are called barges.  Basin: The water area formed in a port on the sea coast protected by an out laying break water is called Basin.
  •  Berth: The space where cargo is unloaded or loaded into a vessel is known as berth.  Breakwaters: The protective barriers constructed to enclose harbours and keep the harbour waters undisturbed by the effect of heavy and strong seas are called break waters.  Dock: the enclosed area provided for berthing ships to keep them afloat at a uniform level to facilitate loading and unloading is called the dock.
  •  Estuary: The harbour constructed along the banks of a river is known as estuary harbour or river harbour.  Harbour: The sheltered area of the sea in which vessels could be launched, built or repaired, or could seek refuge during storm time and provide loading and unloading facilities of cargo and passengers is called harbour.  Hinter land: The area on the land side of the port from where the port may get freight and passengers for transportation is known as hinterland.
  •  Jetty: A piled solid or open type structure built out from the shore to deep water to berth vessels along side is called a jetty. or It is a narrow structure projecting from the shore into the deep water with berths on both sides and some times on end also.  Littoral drift: The exposed coasts are subjected to erosion at certain sections and siltation at some other sections due to wind and waves striking the shore. These waves tend to stir up and move the lighter particles of the sand in suspension. This process of movement and deposition of sand near the fore shore is known as littoral drift.
  •  Navigational aids: the devices such as lights, signals used to guide and warn safe, efficient, economic and comfortable travel of ships in rivers, oceans and harbors are known as navigational aids.  Piers: The structures constructed perpendicular or oblique to the shore of the sea or river to provide bathing facilities are known as piers.  Quays: The platforms constructed parallel to the shore to allow ships to berth along sides these platforms for loading and unloading purposes are called quays.
  •  Wharves: The landing platforms or places in the form of walls built near the shore for vessels to berth are known as wharves.  Transit sheds: A covered arrangement for a temporary storage of incoming and out going cargo requiring protection and storage for a short time is called transit shed.  Ware houses: The permanent structures provided on shore or behind transit sheds for storage for goods for longer periods are known as ware houses or storage go downs.
