A detailed idea about the names and functions of the parts and

sections of a Ship

Anchor: A device, usually made of steel, used to hold a ship against the

movement of current, tide, and wind.

Ballast tank: A watertight compartment used to hold ballast.

Baseline: An imaginary horizontal line, drawn throughout the molded

hull of the vessel, often the keel, from which vertical distances may be

measured.

Bilge: A section between the bottom and the side of the vessel; the

lowest part of the vessel into which water drains.

Bilge keel: A vane mounted on the outside of a ship at the turn of the

bilge perpendicular to the hull to reduce rolling effect.

Bridge house: A part of the upper superstructure of a ship, where the

officer’s quarters, staterooms, and accommodations are located.

Pilothouse is located above it.

Bow Thruster: A bow thruster or stern thruster is a transversal

propulsion device built into, or mounted to, either the bow or stern, of a

ship or boat, to make it more maneuverable. Bow thrusters make

|

Tra

docking easier, since they allow the captain to turn the vessel to port or

starboard side, without using the main propulsion mechanism which

requires some forward motion for turning. A stern thruster is of the same

principle, fitted at the stern. Large ships might have multiple bow

thrusters and stern thrusters.

Bulbous Bow: The purpose of bulbous bow is to change the nature of

this bow wave to reduce the drag it induces on the hull The bulbous bow

creates its own wave that is farther forward and "out of phase" with the

natural bow wave created by the hull, effectively subtracting from the

normal bow wave and reducing its drag-inducing effect.

Bulk carrier: Ships, which are designed to carry bulk cargo such as

coal, ore, grain, etc.

Bulkhead: A vertical partition which sub divides the interior of a ship

into compartments or rooms. Bulkheads, which contribute to the strength

of a vessel, are called strength bulkheads. Those, which contribute for

watertight subdivision, are called watertight bulkheads. Gastight

bulkheads serve to prevent the passage of gas or fumes.

9


Centerline (Longitudinal): A vertical center line between fore and aft

sides dividing the ship into two symmetrical halves.

Chock: A cut piece of plating used to terminate a structural shape at its

end or to support a structural shape. Used under Motors for ships

running on DG and Thruster. This is to allow permissible movement to

the motors during operation.

Cofferdam: Narrow void space between two bulkheads or floors to

prevent leakage between the adjoining compartments; also used

for insulation purposes.

Crane: A device for lifting and moving heavy weights by means of a

movable projecting arm and a horizontal beam.

Deck: A horizontal surface in a ship. It is the plating, planking, or

covering of any tier beams in either the hull or the superstructure of a

ship. Decks are usually designated by their location, as boat deck, bridge

deck, upper deck, main deck, etc. Decks at various levels serve different

functions; they may be either watertight decks, strength decks, or simply

cargo and passenger accommodation decks.

Diesel Engine: A diesel engine (also known as a compression-ignition

engine) is an internal combustion engine that uses the heat of

compression to initiate ignition to burn the fuel, which is injected into

the combustion chamber.

Diesel Generator: A diesel generator is the combination of a diesel

engine with an electrical generator (often an alternator) to generate

electrical energy. Diesel generating sets are used in places without

connection to the power grid, as emergency power-supply if the grid

fails.

Double bottom: Compartment at the bottom of a ship between inner

bottom and the shell plating, mostly used for ballast water, fresh water

or fuel oil.

Engine room: The place on board a ship, where main propulsion and

auxiliary machinery of a ship are located.

11


Erection: The connection of all the subassemblies, blocks and outfit

units of a ship, either on slip ways or any other building position.

Fender: A device made of wood or rubber built or hung over around the

side of a ship to prevent the shell plating from rubbing or chafing around

other ships or piers.

Frame: A term used to designate one of the transverse members the rib

like part of the skeleton of a ship. The frames act as stiffeners holding

the outside plating in shape and maintaining the transverse form of the

ship.

Frame spacing (Transverse): The fore and aft distance, heel to hell or

web to web, of adjacent transverse frames, depending on the shape or

frame used.

Funnel: A chimney through which combustion products are lead from

propulsion and auxiliary machinery to the weather.

Galley: A cook room or kitchen of a ship.

Girder: A large strengthening member to support horizontal or vertical

loads. It is larger than a longitudinal or stiffener.

Hold: The large space below the main deck for the stowage of cargo.

Hull: The hull is the main body of the ship below the main outside deck.

The hull consists of an outside covering (or skin) and an inside

framework to which the skin is secured. The skin and framework are

usually made of steel and secured by welding. However, there may still

be some areas where rivets are used. The steel skin may also be called

shell plating.

Emergency Position-Indicating Radio Beacon (EPIRB)

A modern EPIRB is a sophisticated device that contains:

A 5-watt radio transmitter operating at 406 MHz or at 0.25-watt radio

transmitter operating at 121.5 MHz

A GPS receiver.

Once activated, both of the radios start transmitting. Approximately

24,000 miles (39,000 km) up in space, a GOES weather satellite in

a geosynchronous orbit can detect the 406-MHz signal. Embedded in the

signal is a unique serial number, and, if the unit is equipped with a GPS

receiver, the exact location of the radio is conveyed in the signal as well.

If the EPIRB is properly registered, the serial number lets the Coast

Guard know who owns the EPIRB. Rescuers in planes or boats can

home in on the EPIRB using either the 406-MHz or 121.5-MHz signal.

Older EPIRBs did not contain the GPS receiver, so the GOES satellite

received only a serial number. To locate the EPIRB, another set

of satellites (like the TIROS-N satellite) orbiting the planet in a

low polar orbit could pick up the signal as it passed overhead. This

would give a rough fix on the location, but it took several hours for a

satellite to come into range.

NAVTEX

Navtex is an international, automated system for instantly distributing

maritime safety information (MSI) which includes navigational

warnings, weather forecasts and weather warnings, search and rescue

notices and similar information to ships. A small, low-cost and self-

contained "smart" printing radio receiver is installed on the bridge, or the

place from where the ship is navigated, and checks each incoming

message to see if it has been received during an earlier transmission, or

if it is of a category of no interest to the ship's master. The frequency of

transmission of these messages is 518 kHz in English, while 490 kHz is

sometime used to broadcast in a local language. The messages are coded

with a header code identified by the using single letters of the alphabet

to represent broadcasting stations, type of messages, and followed by

two figures indicating the serial number of the message. For

example: FA56 where F is the ID of the transmitting station, A indicates

the message category Navigational warning, and 56 is the consecutive

message number.

Search and Rescue Locating device

The GMDSS installation on ships include one Search and Rescue

Locating device called Search and Rescue Radar Transponders (SART)

which are used to locate survival craft or distressed vessels by creating a

series of twelve dots on a rescuing ship's 3 cm radar display. The

detection range between these devices and ships, dependent upon the

height of the ship's radar mast and the height of the Search and Rescue

Locating device, is normally about 15 km (8 nautical miles). Once

detected by radar, the Search and Rescue Locating device will produce a

visual and aural indication to the persons in distres

caused by rain, the Synapsis Radar offers, apart from the common FTC

function the well-proven and patented Raytheon RainRate© function,

which measures the actual rain attenuation and applies continuous

filtering. User settings: The Synapsis Radar allows easy storage of

up to 5 different user settings.The operators benefit from reduced

workload and optimised display settings to improve operational safety.

SeaScout supports the navigator finding a save way and avoiding

situations of possible collision. The new function analyses the

movement of the plotted objects and determines in which areas the

danger causes by a possible crash is exceptional high. These areas are

displayed as a hatched field. If the navigator avoids these so-called “No

Go Areas”, he navigates most probably on a safe route. SeaScout shows

true zones (in relation to other true objects e.g. chart underlay, buoys,

true marks, traffic separation zones, nav lines). The function Trial

Manoeuvre cooperates perfectly with SeaScout. If within Trial

Manoeuvre just the course is changed, The results are already included

delay in the trial manoeuvre now shows its influence within SeaScout

and gives the operator a more comprehensive overview about the traffic

situation and possible solutions.

AIS

AIS targets can be displayed on the radar video, detailed information

on targets can be shown on request and alarms for lost or dangerous AIS

targets will be generated. It is possible to

display up to 3 targets: AIS identifier no., status, course, speed,

distance, true bearing, closest point of approach, and time to

closest point of approach. The type of AIS symbol shows if it is

a sleeping target, a normal target, a selected target, a dangerous

target or a lost target.
