L<str<strong>on</strong>g>is</str<strong>on</strong>g>t of Capacities and Cooling Water Systems<br />
The L<str<strong>on</strong>g>is</str<strong>on</strong>g>t of Capacities c<strong>on</strong>tain data regarding the<br />
necessary capacities of the auxiliary machinery<br />
for the main engine <strong>on</strong>ly, and refer to a nominally<br />
rated engine. Complying with IMO Tier I NO x limitati<strong>on</strong>s.<br />
The heat d<str<strong>on</strong>g>is</str<strong>on</strong>g>sipati<strong>on</strong> figures include 0% extra<br />
margin for overload running except for the scavenge<br />
air cooler, which <str<strong>on</strong>g>is</str<strong>on</strong>g> an integrated part of the<br />
diesel engine.<br />
Cooling Water Systems<br />
The capacities given in the tables are based <strong>on</strong><br />
tropical ambient reference c<strong>on</strong>diti<strong>on</strong>s and refer to<br />
engines with high efficiency/c<strong>on</strong>venti<strong>on</strong>al turbocharger<br />
running at nominal MCR (L ) for:<br />
• Seawater cooling system,<br />
See diagram, Fig. 6.02.0 and nominal capacities<br />
in Fig. 6.03.0<br />
• Central cooling water system,<br />
See diagram, Fig. 6.02.02 and nominal capacities<br />

The capacities for the starting air receivers and<br />
the compressors are stated in Fig. 6.03.0 .<br />
Heat radiati<strong>on</strong> and air c<strong>on</strong>sumpti<strong>on</strong><br />
The radiati<strong>on</strong> and c<strong>on</strong>vecti<strong>on</strong> heat losses to the<br />
engine room <str<strong>on</strong>g>is</str<strong>on</strong>g> around % of the engine nominal<br />
power (kW in L ).<br />
The air c<strong>on</strong>sumpti<strong>on</strong> <str<strong>on</strong>g>is</str<strong>on</strong>g> approximately 98.2%<br />
of the calculated exhaust gas amount, ie.<br />
M air = M exh x 0.982.<br />
Flanges <strong>on</strong> engine, etc.<br />
The locati<strong>on</strong> of the flanges <strong>on</strong> the engine are<br />
shown in: ‘Engine pipe c<strong>on</strong>necti<strong>on</strong>s’, and the flanges<br />
are identified by reference letters stated in the<br />
‘L<str<strong>on</strong>g>is</str<strong>on</strong>g>t of flanges’; both can be found in Chapter 5.<br />
The diagrams use the ‘Basic symbols for piping’,<br />
whereas the symbols for instrumentati<strong>on</strong> according<br />
to ‘ISO 2 9� ’ and ‘ISO 2 9�2’ and the instrumentati<strong>on</strong><br />
l<str<strong>on</strong>g>is</str<strong>on</strong>g>t found in Appendix A.<br />
