Linear Dimensions
• Length: Distance between
stern and bow at ships.
Linear Dimensions
• Beam: Distance from port
side to starboard side.
Measured at amidships.
Linear Dimensions
• Depth: Distance between
the undersides of the deck
amidships to the keel´s
bottom.
Tonnage Capacity

• Light
• Load
• Deadweight
• Gross Tonnage
• Net Tonnage
• Cargo Deadweight
Conclusion
A ship's size and capacity can
be described in two ways--
linear dimensions or tonnages.
Each is completely different but
are related.
Troop Ships
Types of Ships
• Vessels can be classified by
their purpose in:
Industrial
• Naval Ships
Ships
Civil Ships
• Civil Ships
Service
• Civil ships are classified
according the use that Ships
everyone will have.
Technical
Ships
Civil Ships Freighters
• Troop Ships: Are ships
designed to carry freight and
passengers

• Freighters: Are vessels Cargo ships
designed to carry freight.

Freighters
• General Cargo Ships:
General cargo includes
items which are packed or
unpacked. They usually
have spacious holds which
occupy the larger part of the
hull.

Specialized Cargo
• Reefer Cargo Ships: They
transport perishable food
such as fruit, vegetables,
meat, fish and dairy, having
a carrying capacity of 8,000
- 12,000 t.
Specialized Cargo
• Timbers Carrier Ships: One-
decked ships designed to carry
logs and beams; carrying
capacity - 5,000 - 20,000 t,
speed - 13-15 knots.
Specialized Cargo
• Containers Ships: These
ships are classified as unit-
load ships because freight is
carried in huge boxes of
standard size (units), usually
from 10 to 40 t.
Specialized Cargo
• Barges-Carrying Ships:
This type of ships pertains
to the category of
containerships but the
principle is slightly different.
Specialized Cargo
• Ro-Ro Ships: Used for
transporting motor vehicles
and other wheeled
equipment. Ro-Ro is short
for roll-on roll-off ships and
is thus called because cargo
is carried on wheeled
containers or trailers.
Specialized Cargo
• Bulk Carriers: Bulk cargo is
a wide term. Heavy bulk-
carriers usually transport
ore, coal and coke, building
materials, such as cement
and gravel. Light bulkers
carry grain, salt and sugar.
Specialized Cargo
• Heavy Cargo Ships: Heavy
cargo vessels can be
divided into: Semi-
submersible heavy lift ships,
conventional heavy lift
ships, tow barges and dock
ships. Their construction
and stability allows them to
carry extremely large and
heavy objects.
Specialized Cargo
• Flo-Flo Ships: Float-on/Float-
off or semisubmersible ships,
provide the capability to load,
transport and offload outsized
military cargo independent of
port equipment traditionally
used for handling large or
extremely heavy cargo, such
as tug boats, barges, landing
craft, floating cranes, and
single anchor leg mooring
systems. Lifts range from
approximately 50 to as much
as 45,000 tons.
Specialized Cargo
• Cattles Ships: as the name
implies, these ships
transport cattle.

designed for transporting
liquefied natural gas (LNG)

transport chemicals such as
sulfuric acid, phosphoric
acid and ammoniac.

either by sail or by power,
used for having fun.

wagons, vehicles and
passengers by serving as a
bridge between two ports,
located at the opposite ends
of rivers, bays, canals, etc.

Whalers
Extractive Ships
• Trawlers: The most
widespread type of fishing
vessel; The name "trawler"
comes from "trawl" - a
fishing net which is dragged
along the sea floor.
Extractive Ships
• Seiners: Seiners use a
peculiar kind of net (a purse
seine) which hangs vertically
in the water and has a rope
at its bottom
Extractive Ships
• Whalers: Ships designed for
hunting whales
Industrial Ships

main purpose is to receive
the catch from extractive
ships, process it into usable
products and bring it to
ports.

vessels with an approximate
length of 60 meters, used
for towing barges and
damaged ships and taking
them across narrow canals

service and create the
Technical Dredges
necessary conditions for
ship navigation. Ships Floating
Docks
Others
Technical Ships
• Dredges: These are
floating vessels used to
make sea- or river-floors
deeper (for example, this is
done when ports and canals
are built or simply
maintained).
Technical Ships
• Suction Dredges: These
crafts have a suction device
which gathers sand from the
sea floor and carries it away
with a system of pipes to
land or to another deep
place in water which has to
be made shallower.
Technical Ships
• Floating Docks: the largest
representatives of technical
ships; Floating docks are
floating vessels which
cannot move on their own
and serve as places for
construction and repair of
ships.
Technical Ships
• Others: floating
cranes, power stations and
workshops; cable laying
ships; oil collector ships
(they surround the oil spills
and clear them); drill ships;
offshore drilling rig supply
vessels;
Conclusion
Our presentation aims to
describe all types of ships by
explaining their typical features,
through the use of pictures. It
dells mainly on troop ships,
because they form the world's
merchant fleet and contribute
essentially to world trade and
transportation.
Do you have
any question???
THANKS
For your attention
