Different Kinds Of Vessel

1.Bulk Carrier

Bulk carriers are a type of ship which transports cargoes in bulk

quantities. The cargo transported in such ships is loose cargo i.e. without any specific
packaging to it and generally contains items like food grains, ores and coals and even
cement.

Parts
 Bridge

The bridge is a room or platform of

a ship from which the ship can be
commanded. When a ship is under way, the
bridge is manned by an officer of the
watch aided usually by an able
seaman acting as a lookout. During critical
maneuvers the captain will be on the bridge,
often supported by an officer of the watch, an
able seaman on the wheel and sometimes
a pilot, if required.
 Anchor

A ships anchor is a heavy device of iron

or steel attached to the ship by a line, a
cable or chain and used to hold the ship
fast to the seabed.

 Deck Crane

Installed on deck they are

operated by an electric motor
( sometimes hydraulically ) and
are capable of lifting loads up to
50 tones. These cranes can be
clearly seen in general cargo
ships as one of the critical parts
of ship.
 Propeller
A propeller is a rotating
fan-like structure that is
used to propel the ship by
using the power generated
and transmitted by the
main engine of the ship.

 Engine Room

On a ship, the engine room (ER)

is the compartment where the
machinery for marine
propulsion is located. ... The
engine room is usually located
near the bottom, at the rear or
aft end of the vessel, and
comprises few compartments.

 Freeboard

In sailing and boating, a vessel's

freeboard is the distance from
the waterline to the upper deck
level, measured at the lowest
point of sheer where water can
enter the boat or ship.
 Rudder
Rudders are hydrofoils which
are pivoting on a vertical axis.
They are located normally at
the stern behind propeller(s) to
produce a transverse force and
steering moment about the
ship centre of gravity by
deflecting the water flow to the
direction of the foil plane.

 Bow
A bow is the front most part of
a ship which cuts the water
along its sides as the ship
proceeds. The key two
requirement for a bow is to
have; minimum drag possible
or so-called resistance
between the water and the
ships hull and must be tall
enough to avoid water splashing to easily on top of it.

 Bow Thrusters
 A bow thruster is a propeller
like device fitted on both side of
ships bow. It is used to increase
the maneuverability of a ship in
congested waters under very
slow speed like that in canals or
near ports.

 Accommodation
It is a place on ship where the crew
resides or live. Together with
offices, crew cabins, gym, prayer
room ( Few ships ), salon,
recreation room, laundry, hospital
and galley it is the heart of a ship
next to engine room and bridge.

 Deck
A deck is a floor or covering to the
ships hull structure. A ship can have
different decks at different section or
parts of ship; namely upper and lower
deck or deck 1, deck 2 and deck 3 in a
sequential downward way. What it
means is that; the topmost deck
exposed to weather is called main
deck or weather deck.
  Ships Hull
A hull is that part of ship that
extends below the waterline to
cover and protect water from
getting in. You can consider it as
the shell which protects the inside
treasures from outside
environment.

Everything that is stored and

situated within the main ship
structure is covered and protected by the ships hull. It includes the key
parts of the ship such as bow, deck, the bottom keel and the both sides of
the ship.

 Keel
A keel is a part of ships hull that is
responsible for providing strength to the
ships structure; spreading stress and
load equally along its longitudinal
sides.Due to its this property to hold and
support ship structure it is often termed
as the backbone of the ship. In simple
terms it provide stability to a ship and
increase its effective speed. The
introduction of keel in shipping reduce much of the work regarding
stabilizing ship structure.
  Funnel
A funnel is what from
which the exhaust gases
are released into
atmosphere. You can
consider it as the chimney
of the ship. Since the
introduction of
mechanized ship; it has
been an integral part of
the ships structure.

The cross section or width

of these funnel largely depends on the amount of exhaust engine room
produce. In early days of shipping it was used to release everything that the
ship emits; but nowadays it is used within the limits of controlled emission
with shoot collection in place to reduce pollution.

2. Tanker Ship/LNG Ship

 A tanker ship with temperature-controlled tanks
which are intended to transport Liquefied Natural Gas (LNG), is
termed as LNG tanker or LNG Ship. ... These vessels, unlike
other tankers, have a propulsion system which is fueled with
natural gas, thus, emitting lesser greenhouse gases.

 Boil of Gas Compressors

LNG BOG(Boil off
gas)compressor's
main role is to keep
the pressure of the
LNG tank within
required range. Gas
suction temperature
is cryogenic, down
to -160 degC(-
256degF) therefore
special considerations and high precision during its design and
manufacturing are necessary.

 Cargo Pumps
Cargo oil pumps are
installed on board
tankers. Their duty is to
pump the oil out of the
vessel's tanks into land-
based tanks at the port
of destination. This
process is supported by
the pumps' stripping
system. In addition, cargo oil pumps are often used as ballast water
pumps to adjust the vessel's draught.
  Reliquefaction Plant
The reliquefaction unit is
built up around the cargo
compressor; where the
compressor is used to
compress cargo boil off
vapour to sufficient pressure
to be liquefied against
normally seawater.
Reciprocating compressors
with labyrinth seals of make
Burckhardt Compression is the definite market leader.

 Anchor
An anchor is a heavy metal piece attached to the chain
cables and is stored or secured in the hose pipe during the
voyage / ship operation. It can be either permanent or
temporary with an additional sub class of sea anchors.
All ships carrying anchors are of the temporary type; as they
are not always fixed to the same position and often lowered at
different position depending upon need. Together with its chain
cables, connecting devices, windlass and chain stopper it is
called anchor gear.
 Bow
A bow is the front most part of a ship which cuts the water
along its sides as the ship proceeds. The key two requirement
for a bow is to have; minimum drag possible or so-called
resistance between the water and the ships hull and must be
tall enough to avoid water splashing to easily on top of it.
 Bow Thrusters
A bow thruster is a propeller like device fitted on both side of
ships bow. It is used to increase the maneuverability of a ship
in congested waters under very slow speed like that in canals
or near ports.

 Accommodation
It is a place on ship where the crew resides or live. Together
with offices, crew cabins, gym, prayer room ( Few ships ), salon,
recreation room, laundry, hospital and galley it is the heart of a
ship next to engine room and bridge.
A salon on board is the common area or living space for its
crew, passengers and any visiting authorities to interact; and
often include common room and dinning space. On another
hand galley is just a nautical term for kitchen; where food is
prepared.
 Deck
A deck is a floor or covering to the ships hull structure. A ship
can have different decks at different section or parts of ship;
namely upper and lower deck or deck 1, deck 2 and deck 3 in
a sequential downward way. What it means is that; the
topmost deck exposed to weather is called main deck or
weather deck.
 Hull
A hull is that part of ship that extends below the waterline to cover
and protect water from getting in. You can consider it as the shell
which protects the inside treasures from outside environment.
Everything that is stored and situated within the main ship structure
is covered and protected by the ships hull. It includes the key parts
of the ship such as bow, deck, the bottom keel and the both sides of
the ship.

 Freeboard
A freeboard stands for the part of ships hull located above the
waterline. It is the distance between the upper deck of ship and the
point of waterline. The freeboard of a ship is not fixed but rather
depends on the amount of cargo it carries.
 Keel
A keel is a part of ships hull that is responsible for providing strength
to the ships structure; spreading stress and load equally along its
longitudinal sides.
 Engine Room
An engine room is the power house of the ship located in the lowest
most deck on aft of the ship. It contains important machinery such as
main engine, auxiliary engine ( Alternator ), shafting, boiler, fresh
water generator, air compressor, calorifier, purifier, incinerator,
pumps, heat exchangers, workshop machineries etc.
 Funnel
A funnel is what from which the exhaust gases are released into
atmosphere. You can consider it as the chimney of the ship. Since
the introduction of mechanized ship; it has been an integral part of
the ships structure.
 Navigation Bridge
If engine room is the heart of the ship; navigation bridge is its brain.
It is an wide platform on top of the accommodation from which the
ship is controlled. They are many a times aided with additional
narrow passage called bridge wing; to allow broader and better view
of the outside to safely maneuver the ship.
 Propeller
It is a fan like mechanical device with blades fitted on the shaft. It
rotates with the shaft to produce much needed thrust to propel a
ship. The propeller of a ship produce this thrust by converting the
rotational energy of its blades to pressure energy.
 Mast
A mast is a vertical ship structure mounted on top of bridge and
forward of the forecastle towards the ships bow. It accounts for the
support platform for the ships derrick and hold necessary equipment
such as radars, navigation light and ships horn in case of foremast.
They are made of high tensile steel with added rigidity based on the
size of derricks it holds. Other than that a ships main mast is also
used to hoist ships flag.

3. Tug Boat
 A tugboat or tug is a marine vessel that manoeuvres other vessels by
pushing or pulling them, with direct contact or a tow line. ... Some are
ocean-going, some are icebreakers or salvage tugs. Early models
had steam engines, and modern ones have diesel engines.

 Towing Line
A tow line is the essential link between tug and ship. This applies to tugs
operating alongside a vessel in the push-pull mode as well as to towing
tugs fastened with a tow line to the bow or stern of a ship, also called
`tugs towing on a line‟.
 Staple
To improve the stability of the tug boat and improve the towing, steering
and arresting ability a towing fairlead (staple) is located at a central
position on the fore deck. In harbor use, the tug can be used assisting in
ship berthing and un-berthing maneuvers.

 Towing Winch
 Tugger winch is the device specially designed for marine towing
operations for different types of ships including offshore support ship, oil
field guard ship, multi-purpose ship etc, for example, towing a ship to
leave or stop at a port or transfer the mooring point, and it's also used to
offer anchor handling .

 Fenders
Tug boat fenders are high abrasion resistance rubber fenders used to
protect the vessel and the other surface during contact. Boat fenders are
also known as boat bumpers, rubber fenders and marine fenders. For
starters, tug boat is a type of boat that maneuvers vessels by towing or
pushing them.

4. Fishing Vessel
 A fishing vessel is a boat or ship used to catch fish in the sea, or on
a lake or river. Many different kinds of vessels are used in commercial, artisanal
and recreational fishing. The total number of fishing vessels in the world in 2016
was estimated to be about 4.6 million, unchanged from 2014.

 Outrigger
Outrigger a beam projected outward from the side of a boat to
secure the masts, sail or hold a floater. ... Side Shell - is the
watertight skin of the boat supported by stiffeners and frames.
  Cross Tree
One of two horizontal crosspieces near the upper end of a section
of mast on a sailing vessel, serving to spread the shrouds for the
section above.

 Tag Lines
Tag lines allow you to use much heavier lures than could be
deployed from the rigger lines. The drop back from tag lines is
greatly reduced. Tag lines offer very little play between the strike
and the line release. Tag lines use a heavy rubber band in place of
a release clip.

 Stabilizer
Ship stabilizers (or stabilisers) are fins or rotors mounted beneath the
waterline and emerging laterally from the hull to reduce a ship's roll
due to wind or waves.

 Trolling Pit
Commercial trolling vessels catch fish by towing astern one or
more trolling lines. The trolling lines are fishing lines with natural
or artificial baited hooks trailed by a vessel near the surface or at
a certain depth.
 Lead Weights
Lead weight means material constructed of lead and applied to a
fishing line or lure and designed to help keep the hook, bait, or
lure underwater.
5. Semi Submersible Vessel
 Semi-submersible may refer to a self-propelled vessel, such as:
Heavy-lift ship, which partially submerge to allow their cargo (another ship) to
float into place for transport. Narco-submarine, some of which remained partially
on the surface.

 Lifting Equipment
The term “lifting appliance” covers all stationary or mobile cargo-handling
appliances. used on board ship for suspending, raising or lowering loads or
moving them from. one position to another while suspended or supported.

 Superstructure
A decked structure on the freeboard deck extending from side to side or
with the side plating not inboard of the shell plating more than 4% of the
breadth (B), (ICLL). A superstructure may be a poop, a raised quarterdeck, a
bridge, a forecastle or a full superstructure.
 Hull
A hull is that part of ship that extends below the waterline to cover and
protect water from getting in. You can consider it as the shell which protects
the inside treasures from outside environment. Everything that is stored and
situated within the main ship structure is covered and protected by the ships
hull. It includes the key parts of the ship such as bow, deck, the bottom keel
and the both sides of the ship.

 Buoyancy Tank
In submersibles and submarines, ballast tanks are used to control the
buoyancy of the vessel. ... They flood ballast tanks to submerge, then to re-
surface either drop discardable ballast weights, or use stored compressed air
to blow their ballast tanks clear of water, becoming buoyant again.

 Working Deck
The deck department is an organisational team on board naval and merchant
ships. ... Seafarers in the deck department work a variety of jobs on a ship or
vessel, but primarily they will carry out the navigation of a vessel, from the
bridge.

6. Crane Vessel
 A crane vessel, crane ship or floating crane is a ship with a crane
specialized in lifting heavy loads. The largest crane vessels are used for offshore
construction. Conventional monohulls are used, but the largest crane vessels are
often catamaran or semi-submersible types as they have increased stability.

 Hook Control Room

A crane hook is a point of attachment on a crane designed to connect with
chains and ropes attached to loads like crates, construction beams, and
machinery. ... Crane hooks are used to attach loads to the crane apparatus.
Cranes allow people to move materials horizontally, as well as vertically.

 Winches and Slewing Structure

Slewing is the rotation of an object around an axis, usually the z axis. ... The
term slewing is also found in motion control applications. Often the slew
axis is combined with another axis to form a motion profile. In crane
 terminology, slewing is the angular movement of a crane boom or crane jib
in a horizontal plane.

 Boom/Jib
A jib or jib arm is the horizontal or near-horizontal beam used in many
types of crane to support the load clear of the main support. ... In other jib-
less designs such as derricks, the load is hung directly from a boom which is
often anomalously called a jib.
