Settling Tank arrangement

General about mixing of fuels. Great care must be taken in order not to mix

different fuels in any tanks. Incompatibility problems may occur that creates

the formation of precipitated asphaltenes forming high viscous sludge. This

sludge may block any strainers, heaters, separators and filters in the entire

fuel system.

In order to provide a fuel handling that minimise the risk of mixing two fuels

of different origin, two settling tanks should be provided. These tanks should

be used alternatively in order to utilise a better settling and stabilising the oiltemperature before being treated by separators.

When only one settling tank is provided, great care must be taken whenchanging from one bunker type to another. The tank must be emptied to a

low level before the new bunker is transferred into the tank.

By doing this is the risk of mixing two fuels of different origin is minimised.Cleaning of the settling tank(s) should be done at least once a year

Service Tank arrangement:

In order to provide a fuel handling that minimisethe risk of mixing two fuels of different origin, twoservice tanks should be provided. These tanksshould be used alternatively in order to avoidmixing of two fuels of different origin at a hightemperature. Cleaning of the service tank(s)

should be done at least once a year.
