Example 2
As an alternative, one common separator unit for max. three engines can be
installed, with one in reserve if possible.
For the calculation in this example it is necessary include the combined aver-
age power demand of the multi-engine plant. The load profile experienced for
the majority of merchant vessels is that the average power demand is around
43-50% of the total GenSet power installed. With three identical engines this
corresponds to 1.3-1.5 times the power of one engine.
â–ª Bulk carrier and tankers : ~1.3 times the power of one engine
â–ª Container vessel : ~1.5 times the power of one engine
For example, for a bulk carrier with three 1,000 kW engines operating on
HFO and connected to a common self-cleaning separator unit, with a daily
effective separating period of 23.5 hours, the calculation is as follows:
With an average power demand higher than 50% of the GenSet power
installed, the operation flow must be based on 100% of the GenSet power
installed.
