Service Letters
In order to ensure the most efficient, economic, and up-to-date operation of the MAN B&W
engines, we, and our licensees, regularly send out ‘Service Letters’, containing first-hand
information regarding accumulated service experience.
The Service Letters can either deal with specific engine types, or contain general instructions
and recommendations for all engine types, and are used as a reference when we prepare
up-dated instruction book editions.
Therefore, since new Service Letters could be of great importance to the operation of the
plant, we recommend that the engine staff file them to supplement the relevant chapters of
this instruction book.

Safety Precautions Chapter 701 Special Dangers

General:
Correct operation and maintenance, which is the aim of this book,
are crucial points for obtaining optimum safety in the engine room.
The general measures mentioned here should therefore be routine
practice for the entire engine room staff.
WARNING !
Keep clear of space below crane with load.
The opening of cocks may cause discharge of hot liquids or gases.
Carefully consider which way liquids, gases or flames will move, and
keep clear.
The dismantling of parts may cause the release of springs.
The removal of fuel valves (or other valves in the cylinder cover) may
cause oil to run down onto the piston crown. If the piston is hot, an
explosion might blow out the valve.
When testing fuel valves, do not touch the spray holes as the jets may
pierce the skin.
Do not stand near crankcase doors or relief valves – nor in corridors
near doors to the engine room casing – when alarms for oil mist, high
lube oil temperature, no piston cooling oil flow, or scavenge box fire is
registered. See also Chapter 704.
WARNING !
In design and layout of the engines, MAN B&W Diesel A/S has the basic
philosophy that the failure of one part should not result in the engine
becoming inoperative.
As some mechanical and electronical parts are essential for the safe
functioning of the engine, such parts are duplicated to achieve redundant
capability.
Should such a redundant part become wholly or partly inoperative, the
failing part must be changed or repaired immediately to re-establish
redundancy of the part or – if an emergency situation requires operation
of the engine – as soon as the vessel calls at the nearest port.

Safety Precautions Chapter 701
701-01
Hydraulic System
Cleanliness
The engine room should be kept clean both above and below the floor plates.
If there is a risk of grit or sand blowing into the engine room when the ship is in
port, the ventilation should be stopped and ventilating ducts, skylights and engine
room doors closed.
Welding, or other work which causes spreading of grit and/or swarf, must not be
carried out near the engine unless it is closed or protected, and the turbocharger
air intake filters covered.
The exterior of the engine should be kept clean, and the paintwork maintained, so
that leakages can be easily detected.
Fire
Do not weld or use naked lights in the engine room, until it has been ascertained
that no explosive gases, vapour or liquids are present.
WARNING !
Before repair or maintenance work is started, the plant must be stopped
and the current be switched off at the main switch. Open the drain valve
to decrease the pressure to zero. During repairs, the drain valve must
be open.
Always measure the pressure and check that the system is depressurized
before disassembling the part concerned from the system.
Never service the hydraulic system when the pumps are running,
unless absolutely necessary (bleeding the system).
Leak detection must always be carried out using a long piece of wood to
secure proper distance to eventually outflowing oil.
Leaking seals cannot be repaired by tightening. Sealing is only possible
by replacing the sealing elements with new parts.
Never carry out welding or soldering on any part of the hydraulic system.
Only use nitrogen as pre-charge gas on accumulators.
WARNING !
Keep the areas around the relief valves free of oil, grease, etc. to prevent
the risk of fire caused by the emitted hot air/gas in the event that
the relief valves open.

Safety Precautions Chapter 701
701-01
If the crankcase is opened before the engine is cold, welding and the use of naked
flames will involve the risk of explosions and fire. The same applies to inspection
of oil tanks and of the spaces below the floor.
Attention is furthermore drawn to the danger of fire when using paint and solvents
having a low flash point.
Porous insulating material, soaked with oil from leakages, is easily inflammable
and should be renewed. See also Sections 704-01, 02 and ‘Sealing Materials’ in
this Section.
Order/Tidiness
Hand tools should be placed on easily accessible tool panels. Special tools should
be fastened in the engine room, close to the area of application.
No major objects must be left unfastened, and the floor and passages should be
kept clear.
Spares
Large spare parts should, as far as possible, be placed near the area of application,
well secured, and accessible by crane.
All spares should be protected against corrosion and mechanical damage. The
stock should be checked at intervals and replenished in good time.
Lighting
Ample working light should be permanently installed at appropriate places in the
engine room, and portable working light should be obtainable everywhere. Special
lamps should be available for insertion through the scavenge ports.
Low Temperatures – freezing
If there is a risk of freezing, then all engines, pumps, coolers, and pipe systems
should be emptied of cooling water, or the cooling water treated to avoid freezing.
Check and Maintain
Measuring equipment, filter elements, and lubricating oil condition.

Safety Precautions Chapter 701
701-01
Entering the Crankcase or Cylinder
Check beforehand that the starting air supply to the engine and the starting air distributor,
is shut off.
In case of oil mist alarm, precautions must be taken before opening to crankcase
(see Section 704-02).
Turning Gear
Before engaging the turning gear, check that the starting air supply is shut off, and
that the indicator cocks are open.
When the turning gear is engaged, check that the indicator lamp “Turning gear in”
has switched on. Check turning gear starting blocking once every year.
Slow-turning
If the engine has been stopped for more than 30 minutes, slow-turning should always
be effected, just before starting in order to safeguard free rotation of the engine,
see Chapter 703.
Feeling over
Whenever repairs or alterations have been made to moving parts, bearings, etc.,
apply the “Feel-over sequence” (see Section 703-03) until satisfied that there is no
undue heating (friction, oil-mist formation, blow-by, failure of cooling water or lubricating
oil systems, etc.).
Feel over after 10-15 minutes’ running, again after 1 hour’s running, and finally
shortly after the engine has reached full load. See Section 703-03.
Sealing Materials
Use gloves when removing O-rings and other rubber/plastic-based sealing materials
which have been subjected to abnormally high temperatures.
These materials may have a caustic effect when being touched directly.
The gloves should be made of neoprene or PVC.
Used gloves must be discarded.
WARNING !
Always ensure that the turning gear is engaged; even at the quay, the
wake from other ships may turn the propeller and thus the engine.

Safety Cap in Starting Air Line
If the bursting disc of the safety cap is damaged due to excessive pressure in the
starting air line, overhaul or replace the starting valve which caused the burst, and
mount a new disc.
If a new disc is not available immediately, turn the cover in relation to the cylinder,
in order to reduce the leakage of starting air.
Alarms
It is important that all alarms lead to prompt investigation and remedy of the error.
No alarm is insignificant. The most serious alarms are equipped with slow-down
and/or shut-down functions. It is therefore important that all engine crew members
are familiar with and well trained in the use and importance of the alarm system.
Mount a new bursting disc and return the cover to the open position at
the first opportunity.

Guidance Value Automation Chapter 701
701-02
701-02 Guidance Value Automation
General Basis for Guidance Values
The values stated in the list on the following pages refer to layout point L1.
(Nominal max. continuous rating).
The values must only be used as a guidance in connection with the ‘List of Capacities
of Auxiliary Machinery’ for dimensioning of auxiliary systems, and must not be
used for determining the extent of the alarms or actions.
The item numbers refer to the drawings showing the extent and placement of sensors
for standard alarms and indicators on the engine, if the signal equipment is
fitted. See Section 701-03, furtheron.
For sensors placed in the systems outside the engine, see the actual pipe arrangements
in the appropriate chapters.
If the engine is provided with special equipment, some values may differ from this
list. The correct values shall in such a case be obtained from the Plant Installation
Drawings.
The engine slow-down level corresponds to 40% of nominal MCR r/min.
Engines specified and optimised at derated power may have other normal service
values depending on layout power/revolutions and application.
For derated engines, the testbed/trial values should be used.
When setting the limits, maximum limits must be set at rising parameter and minimum
limits at falling parameter.
