The steam tracing of the fuel oil pipes is intended
to operate in two situations:
1. When the circulation pump is running, there
will be a temperature loss in the piping, see
Fig. 7.04.02. This loss is very small, therefore
tracing in this situation is only necessary with
very long fuel supply lines.
2. When the circulation pump is stopped with
heavy fuel oil in the piping and the pipes have
cooled down to engine room temperature, as
it is not possible to pump the heavy fuel oil.
In this situation the fuel oil must be heated to
pumping temperature of about 50 ºC.
To heat the pipe to pumping level we recom-
mend to use 100 watt leaking/meter pipe.

In order to fulfil IMO regulations, fuel oil and lubri-
cating oil pipe assemblies are to be enclosed by
spray shields as shown in Fig. 7.04.04a and b.
