2. Operating Ranges

2.1 Engine operating range

Running 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.

2.1.1 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 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.

2. Operating RangesWärtsilä 46F Product Guide

The propulsion control must also include automatic limitation of the load increase rate. Maximum loading rates can be found later in this chapter.
Fig 2-1 Operating field for CP Propeller, IMO Tier 2, 1200 kW/cyl, 600 rpm
DAAB605814 2-1

2.2 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.
If the control system has only one load increase ramp, then the ramp for a preheated engine should be used. The HT-water temperature in a preheated engine must be at least 70 ºC and the lubricating oil temperature must be at least 40 ºC.
The loading ramp “normal” can be taken into use when the engine has been operating above 30% load for 6 minutes. All engines respond equally to a change in propulsion power (or total load), also when a recently connected engine is still uploading to even load sharing with parallel engines. A recently connected generator shall therefore not be taken into account as “available power” until after 6 minutes, or alternatively the available power from this generator is ramped up to 100% during 10 minutes. If the load sharing is based on speed drop, the power management system ramps up the load on a recently connected generator according to the ramp “preheated”.
The “emergency” loading ramp can be used in critical situations, e.g. to steer as fast as possible.
The emergency ramp can be activated manually or according to some predefined condition, and there shall be a visible alarm indicating that emergency loading is activated.
Wärtsilä 46F Product Guide2. Operating Ranges
The load should always be applied gradually in normal operation. Class rules regarding load acceptance capability of diesel generators should not be interpreted as guidelines on how to apply load in normal operation. The class rules define what the engine must be capable of, if an unexpected event causes a sudden load step.
Electric generators must be capable of 10% overload. The maximum engine output is 110% in diesel mode.

2.2.1 Mechanical propulsion, controllable pitch propeller (CPP)

Fig 2-2 Maximum load increase rates for variable speed engines
If minimum smoke during load increase is a major priority, slower loading rate than in the diagram can be necessary below 50% load.
2-2 DAAB605814
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).

2.2.2 Diesel electric propulsion

2. Operating RangesWärtsilä 46F Product Guide
Fig 2-3 Maximum load increase rates for engines operating at nominal speed
In normal operation the load should not be reduced from 100% to 0% in less than 15 seconds. In an emergency situation the full load can be thrown off instantly.
The maximum deviation from steady state speed is less than 10%, when applying load according to the emergency loading ramp. Load increase according to the normal ramp correspondingly results in less than 3% speed deviation.
2.2.2.1 Maximum instant load steps
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 for an engine that has attained normal operating temperature 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.
2.2.2.2 Start-up time
A diesel generator typically reaches nominal speed in about 25 seconds after the start signal. The acceleration is limited by the speed control to minimise smoke during start-up.

2.3 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)
DAAB605814 2-3
Wärtsilä 46F Product Guide2. Operating Ranges
● Maximum 10 minutes if the engine is to be stopped after the idling. 3 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.

2.3.1 Operating at low and load and idling with S.C.R. (Warstila NOR)

When engine is coupled with a Selective Catalytic Reduction system, 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 2 hours in LFO if the engine is to be loaded after the idling. Before further
operation at idling, the engine must be loaded according to the indications reported in the Selective Catalytic Reduction system resetting operation section.
● Maximum 1 hour in HFO if the engine is to be loaded after the idling. Before further operation
at idling, the engine must be loaded according to the indications reported in the Selective Catalytic Reduction system resetting operation section.
Operation below 10% MCR
● Max continuous operation time: 6h in LFO. At intervals of 6 operating hours, the engine
must be loaded according to the indications reported in the Selective Catalytic Reduction system resetting operation section.
● Max continuous operation time: 3h in LFO. At intervals of 3 operating hours, the engine
must be loaded according to the indications reported in the Selective Catalytic Reduction system resetting operation section.
Operation below 25% MCR
● Max continuous operation time: 24h in LFO. At intervals of 24 operating hours, the engine
must be loaded according to the indications reported in the Selective Catalytic Reduction system resetting operation section.
● Max continuous operation time: 12h in HFO. At intervals of 12 operating hours ,the engine
must be loaded according to the indications reported in the Selective Catalytic Reduction system resetting operation section.
Operation above 25% MCR
● No restrictions.
Selective Catalytic Reduction system resetting operation
In case engine has to be run for prolonged time at low loads, Selective Catalytic Reduction system resetting operation must be performed at the intervals indicated, as follows:
Engine must be loaded to minimum 70 % of the rated output for 1 hour or to minumum 50 % of the rated output for 2 hours or alternatively engine must be loaded to minumum 25 % of the rated output for 4 hours.
SCR resetting operation can be split into multiple operational events in case extended high load operation is not feasible. As an example, one 1 hour engine operation at 70 % of the
2-4 DAAB605814
rated output can be replaced by 2 times 30 minute engine operation at 70 % of the rated output. Note that shorter duration than 30 minutes is not recommended.

2.4 Low air temperature

The minimum inlet air temperature of 5°C applies, when the inlet air is taken from the engine room.
Engines can run in colder conditions at high loads (suction air lower than 5°C) provided that special provisions are considered to prevent too low HT-water temperature and T/C surge.
For start, idling and low load operations (Ch 2.3), suction air temperature shall be maintained at 5°C.
If necessary, the preheating arrangement can be designed to heat the running engine (capacity to be checked).
For further guidelines, see chapter Combustion air system design.
