Emergency Start
Further, the MDO must be available as a fuel in
emergency situations.
If a black-out occurs, starting up the auxiliary engines
on MDO can be seen in three ways:
– The MDO is supplied from the MDO booster
pump which can be driven pneumatically or
electrically. If the pump is driven electrically it must
be connected to the emergency switchboard.

– If the engine has a built-on booster pump, it
can be used if the minimum level in the MDO service
tank corresponds to or is max. 1.0 m below the level
of the built-on pump. However, in the design of the
entire system, level of the service tank under the
engine can cause problems with vacuum in the
system.
If not a gravity tank (100 - 200 l) may be arranged
above the engine.
– If no pumps are available, it is possible to start
up the engine on MDO if a tank - as mentioned above
- is placed minimum 8 m above the engine.
