Calculation of List of Capacities and Exhaust Gas Data
Updated engine and capacities data is available
from the CEAS program on www.mandiesel.com
under ‘Marine’
→
‘Low speed’
→
‘CEAS Engine
Room Dimensions’.
This chapter describes the necessary auxiliary ma-
chinery capacities to be used for a nominally rated
engine. The capacities given are valid for seawater
cooling system and central cooling water system,
respectively. For derated engine, i.e. with a speci-
fied MCR and/or optimising point different from the
nominally rated MCR point, the list of capacities
will be different from the nominal capacities.
Furthermore, among others, the exhaust gas data
depends on the ambient temperature conditions.
Based on examples for a derated engine, the way
of how to calculate the derated capacities, fresh-
water production and exhaust gas amounts and
temperatures will be described in details.
Nomenclature

duction and exhaust gas data, the below nomenclatures are used:

Engine configurations related to SFOC
The engine type is available in the following two
versions with respect to the efficiency of the tur-
bocharger:
•
A) With high efficiency turbocharger:
which is the basic design and for which the lists
of capacities Section 6.03 are calculated.
Parameters
Q = Heat dissipation
V
= Volume flow
M = Mass flow
T
= Temperature
Cooler index
air
scavenge air cooler
lub lube oil cooler
jw
jacket water cooler
cent central cooler
Flow index
sw
seawater flow
cw
cooling/central water flow
exh
exhaust gas
fw
freshwater
•
B) With conventional turbocharger,:
Which is an optional design (EoD No. 4 59 107)
if a higher exhaust gas temperature is required
for the exhaust gas boiler. This modification
will lead to a 78% reduction in the exhaust gas
amount and a temperature increase of about
20°C. The SFOC penalty will be 2 g/kWh. The
corresponding lists of capacities are shown in
Section 6.03.
