1 Engine room arrangements
?Auxiliary machinery coverts everything on
board except the main engines,and
includes almost all the pipes and fittings as
well as many items of equipment providing
the following functions.
1 Engine room arrangements
? Supply the requirements of the main
engines - circulating water,forced
lubrication,feed and feed heating,
coolers,condensers,air compressors,oil
fuel reception,transfer and treatment.
? Keep the ship dry and trimmed – bilge
and ballast systems.
1 Engine room arrangements
? Supply the domestic requirements - fresh,
salt,sanitary and sewage systems,
refrigeration,heating and ventilating.
? Apply the main power for propulsion
and manoeuvring-shafting,propellers,
steering gear,stabilizers.
1 Engine room arrangements
? Supply the ship with electric power and
lighting –steam and diesel generating
engines.
? Moor the ship and handle cargo-windlass,
capstan,winches and cargo oil pumps.
? Provide for safety-fire detection and
fighting,lifeboat engines and launching
gear,watertight doors.
1 Engine room arrangements
?Provide for data logging,remote control
and automatic action-pneumatic electro-
pneumatic,and electronic equipment,self-
regulating apparatus,etc.
?The chapter will give a general instruction
above system and function,The other
chapters of the book focus on the oil
handling devices onboard.
1 Engine room arrangements(1)
?The seaman making his first voyage may
not at first realize that the essentials of
certain arrangements do not vary greatly
from ship to ship,
?After some experience he will find that he
can familiarize himself in a strange ship
quite rapidly with,for example,bilge,
ballast,oil fuel transfer,fresh water,
sanitary water and other important
systems.
1 Engine room arrangements(1)
?It is a good idea to be painstaking and to
trace the piping carefully,even laboriously,
until the arrangements are fully understood,
The knowledge so gained may be very useful
on one wild night in the darkness.
1.1 Remote control
?In the last twenty years,developments have been
numerous and rapid; the powers of single engines
have increased dramatically,remote and
automated controls operated from air-conditioned,
sound-proof compartments have come into
common use,
?As these devices are now reliable,engine rooms
are often unmanned for long periods,
1.1 Remote control (1)
?These changes have naturally been accompanied
by some simplification of main systems,but have
brought about a great increase in auxiliary
equipment,
?Low temperature cascade evaporators are usual,
often utilizing waste heat,
?Relatively elaborate treatment of oil fuel,
lubricating oil,boiler feed water and drinking
water have become normal practice.
1.1 Remote control (3)
?A large amount of control equipment
demands clean,dry,oil-free air and the
compressors to provide it,
?The oil-lubricated stern-tube is general,as
is underwater discharge of sewage,often
treated and the refrigeration load for air-
conditioning commonly exceeds that for
cargo,
1.1 Remote control
?Tables 1.1 list the more important auxiliaries in
two modern vessels; ships A and B are single-
screw motor-ships,The proliferation of tanks,
small pumps and heat exchangers is apparent.
?Note that there is a tendency to provide pumps in
duplicate for essential services and to keep
systems simple and separate,though it is not
unusual to install three pumps,one dual-
connected,instead of four,to give effective
duplication,

1.1 Remote control
?It is usual to have only two sea inlet
openings,one port,one starboard,with a
pipe connection from a valve at a higher
level,for use in shallow water.
?Each opening on which all sea suction
valves are mounted,is fitted with a strainer
and weed-clearing valve (also sometimes a
heating connection),
1.1 Remote control
?The freshwater engine-cooling systems in
motorships work under positive head,i.e,a
header tank placed at a greater height than
the highest engine cooling water outlet is
connected in the system; all air vents are
led to this tank and to it all make-up water
is added.
