Due to the increasing request of the ship owners and classification societies to test
the OMD-System at running engines SCHALLER AUTOMATION recommends now
following procedure.
The first test must be performed at standstill to secure, that the engine is well
protected by the OMD system. If it is not possible to open the service covers or if it
is not possible to access the suction funnels, e.g. on large 2-stroke engines, a
functional test can be performed alternatively using a special connection on the
siphon block or respectively on the T-engine wall connection.
Fill the fog bag completely with fog and close the adapter with the yellow cap. The
next step is to press the flexible hose of the fog bag adapter over the opened plug
at the side of the siphon blocks as seen in
T-engine wall connections. Do not remove the hose until an oil mist alarm is
indicated and the search run to indicate the affected compartment is finished. The
plugs can be countered by an 11 mm jaw wrench to open or close the lock screw.
Attention: Let in fog at sampling points of all compartments
including chain/gear drive.
The second test can be performed on request at running engine using the plugs of
the siphon block or the T-engine-wall connection to induce the fog.
