Updated turbocharger data based on the latest
information from the turbocharger makers are
available from the Turbocharger Selection pro-
gram on www.marine.man.eu → ’Two-Stroke’ →
’Turbocharger Selection’.
The data specified in the printed edition are valid
at the time of publishing.
The MC/ME engines are designed for the applica-
tion of either MAN, ABB or Mitsubishi (MHI) turbo-
chargers.
The turbocharger choice is made with a view to
obtaining the lowest possible Specific Fuel Oil
Consumption (SFOC) values at the nominal MCR
by applying high efficiency turbochargers.
The engines are, as standard, equipped with as
few turbochargers as possible, see Table 3.01.01.
One more turbocharger can be applied, than the
number stated in the tables, if this is desirable due
to space requirements, or for other reasons. Ad-
ditional costs are to be expected.
However, we recommend the ‘Turbocharger Se-
lection’ program on the Internet, which can be
used to identify a list of applicable turbochargers
for a specific engine layout.
For information about turbocharger arrangement
and cleaning systems, see Section 15.01.
