TYPES OF SHIP
1. Liner Ships
Liner ship Service –
is a service that operates within a schedule and has a fixed port rotation with
published dates of calls at the advertised ports. A liner service generally
fulfills the schedule unless in cases where a call at one of the ports has been
unduly delayed due to natural or up-normal cause.
2.Tramp Ship
Tramp or tramper is a
ship that has no fixed routing or itinerary or schedule and is available at
short notice (or fixture) to load any cargo from any port to any port
3. Passenger Ships
is a ship whose
primary function is to carry passengers. The category does not include cargo
vessels which have accommodations for limited numbers of passengers, such as the
ubiquitous twelve-passenger freighters once common on the seas in which the
transport of passengers is secondary to the carriage of freight. The type does
however include many classes of ships designed to transport substantial numbers
of passengers as well as freight. Indeed, until recently virtually all ocean
liners were able to transport mail, package freight and express, and other
cargo in addition to passenger luggage, and were equipped with cargo holds and
derricks, kingposts, or other cargo-handling gear for that purpose. Only in
more recent ocean liners and in virtually all cruise ships has this cargo
capacity been eliminated.
While typically
passenger ships are part of the merchant marine, passenger ships have also been
used as troopships and often are commissioned as naval ships when used as for
that purpose.
4. Tanker ships
A tanker (or tank ship
or tankship) is a ship designed to transport liquids in bulk. Major types of
tankship include the oil tanker, the chemical tanker, and the liquefied natural
gas carrier.
5.Liquid Gas Carriers
An LNG carrier is a
tank ship designed for transporting liquefied natural gas (LNG). As the LNG
market grows rapidly, the fleet of LNG carriers continues to experience
tremendous growth.
- Liquefied petroleum
gas carrier (LPG)
- Liquefied natural
gas carrier (LNG)
6. BULK VESSELS
A bulk carrier, bulk
freighter, or bulker is a merchant ship specially designed to transport
unpackaged bulk cargo, such as grains, coal, ore, and cement in its cargo
holds. Since the first specialized bulk carrier was built in 1852, economic
forces have fueled the development of these ships, causing them to grow in size
and sophistication. Today's bulkers are specially designed to maximize
capacity, safety, efficiency, and to be able to withstand the rigors of their
work.
Today, bulkers make up
40% of the world's merchant fleets and range in size from single-hold
mini-bulkers to mammoth ore ships able to carry 400,000 metric tons of
deadweight (DWT). A number of specialized designs exist: some can unload their
own cargo, some depend on port facilities for unloading, and some even package
the cargo as it is loaded. Over half of all bulkers have Greek, Japanese, or
Chinese owners and more than a quarter are registered in Panama. Korea is the
largest single builder of bulkers, and 82% of these ships were built in Asia.
A bulk carrier's crew
participates in the loading and unloading of cargo, navigating the ship, and
keeping its machinery and equipment properly maintained. Loading and unloading
the cargo is difficult, dangerous, and can take up to 120 hours on larger
ships. Crews can range in size from three people on the smallest ships to over
30 on the largest.
Bulk cargo can be very
dense, corrosive, or abrasive. This can present safety problems: cargo
shifting, spontaneous combustion, and cargo saturation can threaten a ship. The
use of ships that are old and have corrosion problems has been linked to a
spate of bulker sinkings in the 1990s, as have the bulker's large hatchways,
important for efficient cargo handling. New international regulations have
since been introduced to improve ship design and inspection, and to streamline
the process of abandoning ship.
7. Container Ship
Container ships are
cargo ships that carry all of their load in truck-size intermodal containers,
in a technique called containerization. They form a common means of commercial
intermodal freight transport.
8. Reefers....
A refrigerator (or
reefer) ship is a type of ship typically used to transport perishable
commodities which require temperature-controlled transportation, mostly fruits,
meat, fish, vegetables, dairy products and other foodstuffs
9. RO – RO Ship
Roll-on/roll-off (RORO
or ro-ro) ships are vessels designed to carry wheeled cargo such as
automobiles, trucks, semi-trailer trucks, trailers or railroad cars that are
driven on and off the ship on their own wheels. This is in contrast to lo-lo
(lift-on/lift-off) vessels which use a crane to load and unload cargo.
RORO vessels have
built-in ramps which allow the cargo to be efficiently "rolled on"
and "rolled off" the vessel when in port. While smaller ferries that
operate across rivers and other short distances often have built-in ramps, the
term RORO is generally reserved for larger ocean-going vessels. The ramps and
doors may be stern-only, or bow and stern for quick loading.
10. Tugs
A tugboat (tug) is a
boat that maneuvers vessels by pushing or towing them. Tugs move vessels that
either should not move themselves, such as ships in a crowded harbor or a
narrow canal, or those that cannot move by themselves, such as barges, disabled
ships, or oil platforms. Tugboats are powerful for their size and strongly
built, and some are ocean-going. Some tugboats serve as icebreakers or salvage
boats. Early tugboats had steam engines, but today have diesel engines. Many
tugboats have firefighting monitors, allowing them to assist in firefighting,
especially in harbors.
