5Preface
This booklet is intend
ed for Licencees, ship
operators, ship
yards, and
marine engineers in general to
illustrate the Unified
Technical File designed
for all MB
D engines req
uired to m
eet the IMO
regulationfor the p
revention of air pollution.
The Unified
Technical File is a docum
ent that specifies a p
rocedure, m
ainly based
on perform
ancem
easurements, b
y which the op
erator can verify comp
liance with the IM
O N
Ox Technical C
ode to the
Flag State A
uthority (or their representative) w
hen the engine is later checked in service.
MA
N B
&W
Diesel has d
esigned this b
ooklet partly to exp
lain survey proced
ures and p
artly as a look-up
manual for IM
O d
efinitions. The first part concentrates on survey routines, from
testbed
to on board
situations (the most im
portant for the op
erator), describ
ing the survey from start to finish. The second
part exp
ands on sp
ecific subjects and
how to hand
le the most com
mon tasks on b
oard, e.g. sp
are orrecond
itioning parts covered
by the regulation.
Regard
ing general emission q
uestions or emission control of M

B&
W D
iesel Two-stroke engines,
reference is given to existing material issued
by M

12 Introduction
The IMO
has introduced
a new A
nnex VI of M
AR
PO
L 73/78, concerning regulation for the prevention
of air pollution from
ships. A
nnex VI ap
plies to all engines d
elivered since 1 January 2000, and
entersinto enforce 19 M
ay 2005.
MA
N B
&W
Diesel has w
orked w
ith the licensees and classification societies to find
a uniform d
esignfor the TF req
uired und
er IMO
Annex V
I, in order to survey on b
oard com
pliance.
Many of the first TFs p
roduced
by the engine b
uilders varied
due to d
ifferent dem
ands m
ade b
y thed
ifferent classification societies. This happ
ened b
ecause the IMO
Annex V
I does not give sufficiently
detailed
instructions on how to d
raw-up
the TF in practice.
MA
N B
&W
Diesel has assum
ed the task of coord
inating the work to p
repare a uniform
TF, to be used
both b
y the licensees and the classification societies. The task also includ
es the necessary proced
uresfor ship
owners w
hen later engine adjustm
ents or changes of comp
onents have occurred.

Advantages
The unified TF m
eans:
C
ertainty of market accep
tance of the TF
Satisfied
customers, w
ho can show engine com
pliance w
hen checked at sea b
y the FlagS
tate representatives
A
survey method
based
on princip
les familiar to the crew
M
ore engines can be accep
ted w
ithin the same engine G
roup, m
eaning reduced
expenses
Less m
oney spent on em
ission measurem
ents.
Parent engines can b
e shared b
etween M
AN
B&
W D
iesel and the licensees. This w
ill greatly reduce
the numb
er ofemission m
easurements and
future certification costs.
3399078.pmd

14 TF Design
The princip
le of the MA
N B
&W
Diesel unified
concept is that the d
efined N
Ox com
ponents and
perform
ance data (m
easurement of p
max , p
comp , T
scav and p
back ) can show
that an engine comp
lies with
the NO
x limit.
Som
e licensees have, in the past, used
a comp
onent setting tolerance instead of p
erformance d
ata.H
owever, if the op
erator has adjusted
the engine, the engine might b
e out of comp
liance when the
engine is later checked b
y the Flag State for com
pliance at sea.
Only extensive tests on Testb
ed can valid
ate engine adjustm
ents when com
ponent settings tolerances
are used. It is im
portant to note that w
hen IMO
Annex V
I is ratified, the focus w
ill be on follow
-up at
sea where changes and
adjustm
ents will take p
lace.
Som
e licensees have slected to use their ow
n develop
ed TF instead
of the recomm
ended
MA
N B
&W
Diesel com
mon com
ponent ID
numb
ers. This will m
ake it much m
ore difficult for the ow
ners top
urchase spare p
arts in the future, and still stay in com
pliance w
ith the IMO
regulation.
It is pred
icted that som
e engines already d
elivered w
ill not be in com
pliance w
hen they are surveyed.
We suggest that all ow
ners who have m
ade changes to their engines contact the m
anufacturerregard
ing its status, before IM
O A
nnex VI com
es into force.

A
Component Changes
This unified TF w
ill allow changes of the engines N
Ox com
ponents, w
hile maintaining com
pliance in
cases where a ship
owner changes com
ponents at sea.
Som
e owners have alread
y dem
anded
a unified system
in order to avoid
working w
ith different TFs.
3399078.pmd
2004-11-12, 12:3815
16 Adjustments
The unified TF w
ill allow all ad
justments on b
oard w
ithin the stated p
erformance p
arameters.
Summ
ary
The Unified
TF is the standard
introduced
by M
AN
B&
W D
iesel and it is accep
ted b
y the classificationsocieties head
quarters. It should
be follow
ed b
y the licensees for all future engines.

A
Concept (engine categories)
The IMO
Annex V
I NO
x technical code d
efines three categories of engines:
1.Ind
ividual E
ngines2.
Engine G
roups
3.E
ngine Families
Individ
ual engine are handled
on the Testbed
, in the same w
ay as a Parent engine. H
owever, a G
roupd
efinition is not included
in the TF.
Engine G
roups and
engine Families consist of a P
arent engine and a num
ber of M
emb
er engines. All
Two-stroke engines can b
e defined
in an engine Group
, either as the Parent engine (rep
resenting theM
emb
er engines) or as a Mem
ber engine.
Most of the survey p
rocedures m
ade for the M
emb
er engines and the P
arent engine app
lication arethe sam
e. The difference for M
emb
er engines is that the emission testing is not necessary neither on
Testbed
nor at sea.

18 B. Survey methods
The survey method
s include Testb
ed, S
ea Trial and O
n board
inspections. The flow
chart for surveym
ethods has b
een split up
into different sections to m
ake a more d
etailed d
escription. R

Engine Fam
ilies
Engine G
roups and
Families consist of a P
arent engine and a num
ber of M
emb
er engines.
Large Two-stroke engines b
elong to either category 1 or 2 because of the necessity for ad
justments on
board
.
In princip
le, most of the survey p
rocedures m
ade for the Ind
ividual and
the Parent engine ap
plication
will b
e the same. The m
ain difference for M
emb
er engines is that the emission testing is not req
uired
neither on the Testbed
nor at sea.
The more engines that can b
e included
in the same engine G
roup, the easier and
lower the costs for
the engine build
er. Furthermore, having a U
nified TF w
ill facilitate sharing of engine Group
s among
MA

&W
Diesel and
the engine build

Excep

Incentives from ind

It is possib

provid

On b

O engine certification should
only be carried
out if absolutely necessary. In ord
er to obtain
an EIA
PP
certificate after installation on board
, the engine must b
e certified either as an Ind

. In princip

When the engine is surveyed
(Testbed
or On b

easured (follow
ing thep
rocedures in the instruction b
ooks) and d
ocumented
through the survey code (and
printed
out to theR
ecord B

mod

log book on b

e used as the R
ecordB

proves the engine setting values, w

AN
B&
W D
iesel Two-stroke engines are for guid
ance only (i.e. for use in cases where the

Ad

panel and
verifiedb
y means of checksum
values. Two checksum
s are defined
for emissions, an IM

(and ap

Engines that alread

Parent

Engines that are d

NO

, therefore, also be consid

For IMO

theIM

it set out in Regulation 13 of A
nnex VI, and
for old engines w
here the mod
ification increasestheir existing N
Ox em
ission level beyond
the tolerances allowed
for a simp

easurement m
ethod.
Due to the d
ifficult conditions for taking m
easurements on b
oard, certain m
easurement tolerances are
allowed
in connection with this m
ethod (see N
Ox Technical C
ode 6.3.11), e.g. 10%
due to the
measurem
ent method
and 10%
due to the p
ossibility of a d
ifferent fuel, but m
aximum
of 15% in total.
For comp
liant engines, if the Parent engines m
aximum
NO
x tolerance is exceeded
, a new P
arentengine m
ust be introd
uced.
For old engines, if N
Ox increases, it w
ould req
uire major effort (if p
ossible at all) to estab
lish a TF andcertify the engine on b
oard. Fortunately, m
ost mod
ifications (introduction of new

, therefore, not result in a requirem
