In the case of a large cruise ship, as much as 6 percent – or up to 2 000 tons of fuel – can be saved annually by engine speed optimisation.

T
he new ABB’s concept has been
accomplished with a simple configu-
ration of electrical system, utilising existing
ABB components. The concept is new to
the commercial maritime industry.
In the case of a large cruise ship, as
much as 6 percent – or up to 2 000 tons
of fuel – can be saved annually by engine
speed optimisation.
Dynamic AC adjusts the rotational
speed of the diesel generating sets, allowing the system frequency to vary within the
specified range. Currently, many ships still
run with their generators at a set speed,
regardless of the power requirement. This
creates a surplus of wasted energy.
Variable speed power generation can
provide significant fuel savings with diesel
electric propulsion, when the operational
profile of the vessel has a lot of variation
in speed and power demand.
