1.2 Reference conditions
The output is available up to a charge air coolant temperature of max. 38°C and an air
temperature of max. 45°C. For higher temperatures, the output has to be reduced according
to the formula stated in ISO 3046-1:2002 (E).
The specific fuel oil consumption is stated in the chapter Technical data. The stated specific
fuel oil consumption applies to engines with engine driven pumps, operating in ambient
conditions according to ISO 15550:2002 (E). The ISO standard reference conditions are:
100 kPatotal barometric pressure
25°Cair temperature
30%relative humidity
25°Ccharge air coolant temperature
Correction factors for the fuel oil consumption in other ambient conditions are given in standard
ISO 3046-1:2002.
1.3 Operation in inclined position
Max. inclination angles at which the engine will operate satisfactorily.

1.4 Arctic package description
When a vessel is operating in cold ambient air conditions and the combustion air to the engine
is taken directly from the outside air, the combustion air temperature and thus also the density
is outside the normal range specified for the engine operation. Special arrangements are
needed to ensure correct engine operation both at high and at low engine loading conditions.
Read more about the special arrangements in chapters Combustion air system design in arctic
conditions, Cooling water system for arctic conditions and Lubricating oil system in arctic
conditions.

2. Operating Ranges
2.1 Engine operating modes
If the engine is configured for SCR use then it can be operated in two modes; IMO Tier 2 mode
and SCR mode. The mode can be selected by an input signal to the engine automation system.
In SCR mode the exhaust gas temperatures after the turbocharger are actively monitored and
adjusted to stay within the operating temperature window of the SCR.
2.2 Engine operating range
Below nominal speed the load must be limited according to the diagrams in this chapter in
order to maintain engine operating parameters within acceptable limits. Operation in the
shaded area is permitted only temporarily during transients. Minimum speed is indicated in
the diagram, but project specific limitations may apply.
2.2.1 Controllable pitch propellers
An automatic load control system is required to protect the engine from overload. The load
control reduces the propeller pitch automatically, when a pre-programmed load versus speed
curve (“engine limit curve”) is exceeded, overriding the combinator curve if necessary. The
engine load is derived from fuel rack position and actual engine speed (not speed demand).
The propulsion control must also include automatic limitation of the load increase rate.
Maximum loading rates can be found later in this chapter.
The propeller efficiency is highest at design pitch. It is common practice to dimension the
propeller so that the specified ship speed is attained with design pitch, nominal engine speed
and 85% output in the specified loading condition. The power demand from a possible shaft
generator or PTO must be taken into account. The 15% margin is a provision for weather
conditions and fouling of hull and propeller. An additional engine margin can be applied for
most economical operation of the engine, or to have reserve power.

Wärtsilä 32 Product Guide2. Operating Ranges
2.2.2 Fixed pitch propellers
The thrust and power absorption of a given fixed pitch propeller is determined by the relation
between ship speed and propeller revolution speed. The power absorption during acceleration,
manoeuvring or towing is considerably higher than during free sailing for the same revolution
speed. Increased ship resistance, for reason or another, reduces the ship speed, which
increases the power absorption of the propeller over the whole operating range.
Loading conditions, weather conditions, ice conditions, fouling of hull, shallow water, and
manoeuvring requirements must be carefully considered, when matching a fixed pitch propeller
to the engine. The nominal propeller curve shown in the diagram must not be exceeded in
service, except temporarily during acceleration and manoeuvring. A fixed pitch propeller for
a free sailing ship is therefore dimensioned so that it absorbs max. 85% of the engine output
at nominal engine speed during trial with loaded ship. Typically this corresponds to about
82% for the propeller itself.
If the vessel is intended for towing, the propeller is dimensioned to absorb 95% of the engine
power at nominal engine speed in bollard pull or towing condition. It is allowed to increase
the engine speed to 101.7% in order to reach 100% MCR during bollard pull.
A shaft brake should be used to enable faster reversing and shorter stopping distance (crash
stop). The ship speed at which the propeller can be engaged in reverse direction is still limited
by the windmilling torque of the propeller and the torque capability of the engine at low
revolution speed.
Fig 2-3 Operating field for FP Propeller, 500 kW/cyl), 750 rpm
2.2.3 Dredgers
Mechanically driven dredging pumps typically require a capability to operate with full torque
down to 80% of nominal engine speed. This requirement results in significant de-rating of the
engine.

2.3 Loading capacity
Controlled load increase is essential for highly supercharged diesel engines, because the
turbocharger needs time to accelerate before it can deliver the required amount of air. A slower
loading ramp than the maximum capability of the engine permits a more even temperature
distribution in engine components during transients.
The engine can be loaded immediately after start, provided that the engine is pre-heated to
a HT-water temperature of 60…70ºC, and the lubricating oil temperature is min. 40 ºC.
The ramp for normal loading applies to engines that have reached normal operating
temperature.
2.3.1 Mechanical propulsion
Fig 2-4 Maximum recommended load increase rates for variable speed engines
The propulsion control must include automatic limitation of the load increase rate. If the control
system has only one load increase ramp, then the ramp for a preheated engine should be
used. In tug applications the engines have usually reached normal operating temperature
before the tug starts assisting. The “emergency” curve is close to the maximum capability of
the engine.
If minimum smoke during load increase is a major priority, slower loading rate than in the
diagram can be necessary below 50% load.
Large load reductions from high load should also be performed gradually. In normal operation
the load should not be reduced from 100% to 0% in less than 15 seconds. When absolutely
necessary, the load can be reduced as fast as the pitch setting system can react (overspeed
due to windmilling must be considered for high speed ships).

Wärtsilä 32 Product Guide2. Operating Ranges
2.3.2 Diesel electric propulsion and auxiliary engines
Fig 2-5 Maximum recommended load increase rates for engines operating at
nominal speed
In diesel electric installations loading ramps are implemented both in the propulsion control
and in the power management system, or in the engine speed control in case isochronous
load sharing is applied. If a ramp without knee-point is used, it should not achieve 100% load
in shorter time than the ramp in the figure. When the load sharing is based on speed droop,
the load increase rate of a recently connected generator is the sum of the load transfer
performed by the power management system and the load increase performed by the
propulsion control.
The “emergency” curve is close to the maximum capability of the engine and it shall not be
used as the normal limit. In dynamic positioning applications loading ramps corresponding to
20-30 seconds from zero to full load are however normal. If the vessel has also other operating
modes, a slower loading ramp is recommended for these operating modes.
In typical auxiliary engine applications there is usually no single consumer being decisive for
the loading rate. It is recommended to group electrical equipment so that the load is increased
in small increments, and the resulting loading rate roughly corresponds to the “normal” curve.
In normal operation the load should not be reduced from 100% to 0% in less than 15 seconds.
If the application requires frequent unloading at a significantly faster rate, special arrangements
can be necessary on the engine. In an emergency situation the full load can be thrown off
instantly.
2.3.2.1 Maximum instant load steps (500 kW/cyl)
The electrical system must be designed so that tripping of breakers can be safely handled.
This requires that the engines are protected from load steps exceeding their maximum load
acceptance capability. The maximum permissible load step is 33% MCR. The resulting speed
drop is less than 10% and the recovery time to within 1% of the steady state speed at the
new load level is max. 5 seconds.
When electrical power is restored after a black-out, consumers are reconnected in groups,
which may cause significant load steps. The engine must be allowed to recover for at least
10 seconds before applying the following load step, if the load is applied in maximum steps.
Wärtsilä 32 Product Guide - a21 - 7 September 2016 2-5
2. Operating RangesWärtsilä 32 Product Guide
2.3.2.2 Maximum instant load steps (580 kW/cyl)
The electrical system must be designed so that tripping of breakers can be safely handled.
This requires that the engines are protected from load steps exceeding their maximum load
acceptance capability. The maximum load steps are 0-28-60-100% MCR without air assist.
Engines driving generators are prepared for air assist, see chapters Technical data and Exhaust
gas system. Sudden load steps equal to 33% MCR can be absorbed also at low load if air
assist is used. If air assist is used, the arrangement of the air supply must be approved by the
classification society.
When electrical power is restored after a black-out, consumers are reconnected in groups,
which may cause significant load steps. The engine must be allowed to recover for at least
10 seconds before applying the following load step, if the load is applied in maximum steps.
2.3.2.3 Start-up time
A diesel generator typically reaches nominal speed in about 20 seconds after the start signal.
The acceleration is limited by the speed control to minimise smoke during start-up. If requested
faster starting times can be arranged.
2.4 Operation at low load and idling
The engine can be started, stopped and operated on heavy fuel under all operating conditions.
Continuous operation on heavy fuel is preferred rather than changing over to diesel fuel at low
load operation and manoeuvring. The following recommendations apply:
Absolute idling (declutched main engine, disconnected generator)
● Maximum 10 minutes if the engine is to be stopped after the idling. 3-5 minutes idling
before stop is recommended.
● Maximum 6 hours if the engine is to be loaded after the idling.
Operation below 20 % load
● Maximum 100 hours continuous operation. At intervals of 100 operating hours the engine
must be loaded to minimum 70 % of the rated output.
Operation above 20 % load
● No restrictions.
NOTE
For operation profiles involving prolonged low load operation, please contact
Wärtsilä.
2.5 Low air temperature
In cold conditions the following minimum inlet air temperatures apply:
● Starting + 5ºC (when running)
● Idling and highload - 5ºC
For lower suction air temperatures engines shall be configured for arctic operation.
For further guidelines, see chapter Combustion air system design.

Notes:
At ISO 15550 conditions (ambient air temperature 25°C, LT-water 25°C) and 100% load. Flow tolerance 5%.Note 1
At ISO 15550 conditions (ambient air temperature 25°C, LT-water 25°C). Flow tolerance 5% and temperature tolerance
10°C.
Note 2
At ISO 15550 conditions (ambient air temperature 25°C, LT-water 25°C) and 100% load. Tolerance for cooling water heat
10%, tolerance for radiation heat 30%. Fouling factors and a margin to be taken into account when dimensioning heat
exchangers.
Note 3
At ambient conditions according to ISO 15550. Lower calorific value 42 700 kJ/kg. Withengine driven pumps (two cooling
water + one lubricating oil pump). Tolerance 5%. Note; SOI is different for MDO and HFO engines. If the engine is made
for operation on both HFO and MDO, the consumption on both fuels will be according to HFO consumption.
Note 4
Automatic (remote or local) starting air consumption (average) per start, at 20°C for a specific long start impulse (DE/AUX:
2...3 sec, CPP/FPP: 4...6 sec) which is the shortest time required for a safe start.
