shipping companies

Engine Room
• Crew Hierarchy
– Chief Engineer
– Second Engineer
– Third Engineer
– Fourth Engineer
– Fifth Engineer
– Engineer Trainees
– Electrical Engineer
Engine Room Department
• The Engine Room department is
responsible for Overall Maintenance of
Ship’s Machinery.
Chief Engineer-Responsibility
• Chief Engineer is responsible for all operations
and maintenance covered by engineering
equipment throughout the entire ship.
• Chief also determines the fuel, lube oil, and
other consumables required for a voyage,
required inventory for spare parts, oversees fuel,
lube, and slop oil transfers, prepares the engine
room for inspection by local marine/safety
authorities, oversees all major maintenance, is
required to be in the engine room during
maneuvering operations, and is in charge of the
engine room during emergency situations.
Second Engineer-Responsibility
• Supervises the daily operation of the
engine room and engine department and
reports directly to the Chief.
• Typically the busiest engineer aboard the
ship
• Usually in charge of preparing the engine
room for arrival, departure, or standby and
oversees major overhauls on critical
equipment.
Engine Room
• An engine room is where the main engine(s),
generators, compressors, pumps,
fuel/lubrication oil purifiers and other major
machinery are located.
• Engine Rooms are typically towards the stern, or
rear, of the boat from the crews living
accommodations.
• On modern ships, a sound-proofed, airconditioned engine control room (ECR) is
situated next to the engine room (ER), for the
ship's machinery control systems.

Main Engine
Auxilliary Engine
Fresh Water Generator
Lube Oil Tank
Fuel Tank
Diesel Oil Tank
Cross-Sectional View of vessel
Main Engine
• Main Engine is connected to the Propeller
and propels the ship.
• Main Engines run using Heavy Oil or
Diesel Oil.

Auxilliary Engine
Auxilliary Engines are required for Ship’s Power
requirement.
When Main Engines do not run (from anchorage to
harbor, canal ways), auxilliary engines will
operate.
There would be 3,4,6,8 Auxilliary engines in a ship
depending on the size of the ship
• Auxilliary Engines are also used in driving
ballast-trim pumps, water circulating pumps,
boiler feed pumps, fuel oil pumps etc.
Auxilliary Engine
Engine Cooling
• The engine(s) get their required cooling by
means of liquid-to-liquid heat exchangers
connected to fresh seawater or divertible to
recirculate to tanks in the engine room which are
also full of sea water.
• The heat exchangers are plumbed in so that oil
is represented by a yellow mark on the flange of
the pipes, and relies on paper type gaskets to
seal the mating faces of the pipes.
• Sea water or brine, is represented by a green
mark on the flanges and internal coolant is
represented by blue marks on the flanges.
Fire Precautions
• Engine rooms are hot, noisy, sometimes
dirty, and potentially dangerous.
• The presence of fuel, high voltage
equipment, engines etc., means that a
serious fire hazard exists in the engine
room, which is monitored continuously.
• Engine rooms employ some means of
providing air for the operation of the
engines and associated ventilation
Engine Control Room
Propeller
– Basically a type of fan which transmits power by converting
rotational motion into thrust for propulsion of ship through
water.
– It is effected by rotating two or more twisted blades about a
central shaft, in a manner analogous to rotating a screw.
– The blades of a propeller act as rotating wings and produce
force through application Newton’s third law.
Rudder and Propeller
Rudder
– A rudder is a device used to steer a ship.
– A rudder operates by redirecting the fluid past the hull
or fuselage, thus imparting a turning or yawing motion
to the craft.
– In basic form, a rudder is a flat plane or sheet of
material attached with hinges to the craft's stern, tail
or after end.
– Often rudders are shaped so as to minimize
hydrodynamic or aerodynamic drag.
– In larger vessels, cables, pushrods and hydraulics
may be used to link rudders to steering wheels. In
typical aircraft, pedals operate rudders via mechanical
linkages.
Drydock
• A drydock is a narrow basin or vessel that
can be flooded to allow a load to be
floated in, then drained to allow that load
to come to rest on a dry platform.
Drydocks are used for the construction,
maintenance, and repair of ships, boats,
and other watercraft.
