•Marine engine Recommendation on applications

The engine must be able to achieve rated engine speed when operated under fully

loaded conditions;

Secondary drive loads must be considered engine horse power which could be available to

drive the primary load. Therefore any such parasitic load requirements must be deducted when

sizing an engine for the primary load.

The engine must be used in accordance with the application guidelines for that

particular rating;

It is important to choose the proper engine rating to provide the optimum performance in a

given application. Ratings below show DOOSAN marine engine guidelines on applications.

CHAPTER 1 ENGINE ROOM

When installing the engine, ensure that there is sufficient space for regular maintenance work

and possible engine overhaul after prolonged periods of operation. It must be possible to carry

out the following jobs on engine and gearbox without obstruction;

•Removing heat exchanger and inter-cooler for cleaning

•Exchanging starter, alternator and water pump

•Filling up with fuel, oil and coolant

•Checking oil and coolant level

•Changing fuel, oil and air filter

•Setting valves, re-tightening cylinder head bolts

•Draining oil and coolant

•Re-tightening and exchanging V - belts

•Maintenance and exchange of battery

•Exchanging injection nozzles

•Changing the sea water pump impeller

•Changing the reduction gear

1.1. Engine Room Ventilation

Calculation of the air requirements for the dissipation of convection and radiation heat can be

simplified the following formula:

where

•

m Air mass flow rate in kg/h

•

Q Convection and radiation in MJ/h

CpSpecific heat capacity of air = 1 kJ/(kg x degree)

Δt Difference in temperature between heated waste air and cold intake air in degrees Celsius

In order to obtain the air volume flow (m3/h) the air mass flow (kg/h) must be divided by the air

density, which depends on the temperature.

Air density as a function of the temperature at the air pressure of 0.98kg/cm2(1000 mbar).

The before-mentioned formula is based on the assumption that the engine room is a heat-tight

system, i.e. for the sake of simplicity it is assumed that no thermal energy whatever is

dissipated through the hull to the ambient air or water.

In practice, however, such heat losses are likely to occur and depend on the following factors:

•Size and surface area of the engine room

•Difference in temperature between the engine room and the ambient air

•Hull material (thermal conductivity) and hull thickness

•Heat dissipation via pipes (e.g. exhaust pipes)

This heat transfer is therefore hard to estimate qualitatively.

Note : The difference of engine room and ambient air temperature (

t) would be better

below than 15

C, but should not exceed maximum 20

Δt = (Air temperature of engine room ) - (Ambient temperature )

•Temperature

t(degree Celsius) = T(Kelvin) - 273

T(Kelvin) = t (degree Celsius ) +273

t (degree Fahrenheit) = 1.8 x t (degree Celsius) + 32

•Pressure

1 kilo-Pascal (kPa) = 10 millibar (mbar)

1 hecto-Pascal (hPa) = 1 millibar (mbar)

•Energy flow

Mega - Joule/hour (MJ/h) x 1000 = Kilocalories/hour (kcal/h)

Mega - Joule/hour (MJ/h) x 1 = Kilowatt (kW)

1.2. Engine Foundation

Requirements for the engine foundation are as following;

•The foundation in the vessel should be able to take up propeller thrust in both directions

(ahead & astern) and transmit it on to the hull.

•The weight of the drive system as well as all dynamic forces that occur in rough seas must

be safely taken up.

•The torsion of the hull owing to rough seas and the load status must not be transferred to

the engine. The engine foundation is to be connected to the hull on an area as large as

possible

Engine bed

Stringer

Engine mounting bracket

EB0O9007

•Transverse cross bracing on the engine

bed and stringers should be used to

prevent lateral engine movement on solid

mounted systems.

•In order to properly support the weight of

the engine and marine gear, a six-point

mounting system is recommended on all

DOOSAN marine engines.

When using a six-point mounting system,

the engine should be aligned using the

mounts at the front and at the marine gear

at first. Once the alignment is complete,

the next flywheel housing mounts should

be added.

1.3. Max. Permissible Engine Inclination

The installation angle of the engine is an important factor in the construction of the sub-frame.

When the engine is to be installed in longitudinal direction, The maximum permissible inclination

must not be exceeded. The maximum permissible inclination is defined as the largest angle that

occurs in driving operation, ie, installation inclination plus the ship’s maximum trim angle.

The maximum installation angle of the engine is the maximum permissible inclination angle ( )

of the boat less the angle of the maximum trim( ) while the vessel is in motion. ie, the maximum

installation angle of the engine is( - ).

= max. permissible vessel inclination angle ; angle towards the flywheel end

= angle towards the non flywheel end

= trim of the vessel

Note : angle

The angle of 5

toward the non-flywheel and must occur only while the vessel

is in motion.
