The number of auxiliary blowers in a propulsion
plant may vary depending on the actual amount of
turbochargers as well as space requirements.
Motor start method and size
Direct Online Start (DOL) is required for all auxilia-
ry blower electric motors to ensure proper opera-
tion under all conditions.
For typical engine configurations, the installed
size of the electric motors for auxiliary blowers are
listed in Table 14.04.01.
Special operating conditions
For engines with Dynamic Positioning (DP) mode
in manoeuvring system, option: 4 06 111, larger
electric motors are required. This is in order to
avoid start and stop of the blowers inside the load
range specified for dynamic positioning. The actu-
al load range is to be decided between the owner
and the yard.
Engine plants with waste heat recovery exhaust
gas bypass and engines with low- and part-load
exhaust gas bypass may require less blower ca-
pacity, please contact MAN Diesel & Turbo, Co-
penhagen.
