system. In case of long suction lines or larger dimensioned
pipelines, another non-return or foot valve should be
installed to prevent permanent drainage of the suction line.
In order to maintain the suction power of the system, the
recommended pipe cross-sections of the suction line
should be met.
If the ship uses a fuel with very high viscosity and/or if
extremely low bilge temperatures are to be expected, we
recommend a heated bilge water tank.
Note
The suction line must be air-tight because the oil
separator operates with a vacuum.
In cause of leaks in the suction line, the oil
separator sucks air. The oil separator then enters a
permanent cycle (air suction, air discharge, etc.).
7.3
Flushing water inlet
WARNING
Lines under pressure bear a risk of injury.
Before taking up the work, check water lines and
make sure that they are not under pressure.
The oil separator system requires clean water with a
pressure of between 1 and max. 1.5 bar at the flushing
water inlet (pos. 15 chapter
à
3.14.3) for oil discharge and
coalescer flashback. In addition to the flushing water inlet,
a connection from the 3-way ball cock at the oil monitor
(pos. 25 chapter
à
3.14.3) must be established to the sea
water cooling system, to the sea water hydrophor system
or to the fresh water hydrophor system for the monitor
zero compensation and for cleaning purposes. The
consumption is low and depends on the oil amount to be
separated and the flushing water pressure. The
approximate consumption amounts to 3% of the OWS
capacity.
7.4
Oil outlet
The pipeline from the oil outlet
(pos. 4 chapter
à
3.14.3) to the oil collector tank must be
laid without pressure. The oil collector tank must be
vented sufficiently.
7.5
Flushing water outlet
The pipeline from the flushing water outlet (figure 4, pos. 5
chapter
à
3.14.3) must be laid without pressure back to
the bilge or into the bilge water tank.
7.6
Clean water outlet
The clean water outlet is the connection at the 3-way valve
(pos. 23 chapter
à
3.14.3) outboards.
