Space Requirements for the Engine

The space requirements stated in Section 5.02
are valid for engines rated at nominal MCR (L
The additional space needed for engines
equipped with PTO is stated in Chapter 4.
If, during the project stage, the outer dimensions
of the turbocharger seem to cause problems, it
is possible, for the same number of cylinders, to
use turbochargers with smaller dimensions by
increasing the indicated number of turbochargers
by one, see Chapter 3.

Overhaul of Engine

The distances stated from the centre of the crank-
shaft to the crane hook are for the normal lifting
procedure and the reduced height lifting proce-
dure (involving tilting of main components). The
lifting capacity of a normal engine room crane can
be found in Fig. 5.04.01.
The area covered by the engine room crane shall
be wide enough to reach any heavy spare part re-
quired in the engine room.
A lower overhaul height is, however, available by
using the MAN B&W DoubleJib crane, built by
Danish Crane Building A/S, shown in Figs. 5.04.02
and 5.04.03.
Please note that the distance 'E' in Fig. 5.02.01,
given for a doublejib crane is from the centre
of the crankshaft to the lower edge of the deck
beam.
MAN B&W MC/MCC, ME/MEC/MEGI/ME-B engines
A special crane beam for dismantling the turbo-
charger must be fitted. The lifting capacity of the
crane beam for dismantling the turbocharger is
stated in Section 5.03.
The overhaul tools for the engine are designed
to be used with a crane hook according to DIN
15400, June 1990, material class M and load ca-
pacity 1Am and dimensions of the single hook
type according to DIN 15401, part 1.
). The total length of the engine at the crankshaft
1
level may vary depending on the equipment to
be fitted on the fore end of the engine, such as
adjustable counterweights, tuning wheel, moment
compensators or PTO.
