Calculation of L<strong>is</strong>t of Capacities and Exhaust Gas Data
Updated engine and capacities data <strong>is</strong> <strong>available</strong>
from the CEAS program on www.mandiesel.com
under ‘Marine’ → ‘Low speed’ → ‘CEAS Engine
Room Dimensions’.
<strong>Th<strong>is</strong></strong> chapter describes the necessary auxiliary machinery
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 specified
MCR and/or matching point different from the

nominally rated MCR point, the l<strong>is</strong>t 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, freshwater
production and exhaust gas amounts and
temperatures will be described in details.
In the following description and examples of the auxiliary machinery capacities, freshwater generator production
and exhaust gas data, the below nomenclatures are used:
Engine ratings Point / Index Power Speed
Nominal MCR point L1 PL1 nL1 Specified MCR point M PM nM Matching point O PO nO Service point S PS nS Fig. 6.01.01: Nomenclature of basic engine ratings

Q = Heat d<strong>is</strong>sipation
V = Volume flow
M = Mass flow
T = Temperature
