Fig. 7.7.3.1-1: Ideal position of the waterlock
In Fig. 7.7.3.1-1, the waterlock is mounted in center
underneath the generator.
When the ship tilts, the position of the waterlock related to the
critical point at the exhaust hose, changes only slightly.

Tilted position 15 degrees - Fig. 7.7.3.1-2
The distance from the exhaust elbow to the hydrostatic head
has derated to 540 mm.

Tilted position 30 degrees - Fig. 7.7.3.1-3
The distance of the water level, even in ideal position,
changes that only 458 mm distance remain. So the critical
distance is under-run already.
Fig. 7.7.3.1-4: Tilted position 45 degrees
Tilted position 45 degrees - Fig. 7.7.3.1-4
In this case the water level rise so high, that the distance
constitutes only 325 mm.
Even when the water lock is mounted in the ideal spot, at an
extremely tilted position of 45 degrees there is still the risk
that water can get straight into the discharge stack area
through strong rocking motions („sloshing“). This shows that
the distance of 600 mm represents a minimum size at which,
even when installed ideally, the water can slosh into the
exhaust elbow when the ship is very tilted or rocks very hard.
