2. 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
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.
3. 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
Dock: the enclosed area provided for berthing
ships to keep them afloat at a uniform level to
facilitate loading and unloading is called the
4. Estuary: The harbour constructed along the

5. 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.
It is a narrow structure projecting from the shore
into the deep water with berths on both sides
and some times on end also.
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.
6. Navigational aids: the devices such as
lights, signals used to guide and warn

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.
7. 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
