Balmoral has an electrical system that was installed in 1949 and
although perfectly suitable for her day, it now needs help from a modern
generator that is currently installed at the rear of the top deck.
Her original system was supplied by a pair of 6 cylinder diesel Lister
generating sets. Balmoral is an all electric ship and apart from
the actual propulsion, everything else depends on electricity, so the
generators are equally as important as her main engines. As built
she had two main generators and a small emergency and standby unit in
the steering flat at the stern. All the ancillary equipment such
as winches, capstans, ventilators and even the water pumps and sewage
system is driven by electricity.
As originally supplied the ship had two 35kw units - that's enough
to boil about 20 kettles or run 20 13 amp fan heaters.
In 1949 that was well sufficient, but today we take electricity for
granted and over the years a much greater load was installed in the ship
and while the generators can handle this, there isn't much spare
capacity. For this reason a third independent unit was installed
on the after deck. This is a large generator and is capable of
supplying the ship on its own, and in this way Balmoral can be sure the
lights won't go out.
In addition, the ship has the facility to connect to the shore supply in
the same way as a caravan can hook up to the mains, so when alongside it
is environmentally better to rely on the domestic electricity supply
than generate her own power.
All this power is connected to a switchboard which is completely
original and fully functional. It is still used to operate the
ship's main systems and is a classic piece of marine engineering.
The main switchboard - it all works and is the main distribution centre
for the ships power.
.... this is the modern generator on the rear of the main deck that can
supplement the ships original generators ....
..... and we have a standby and emergency generator right at the stern
of the ship that would power the emergency and navigation lights and
basic services when the ship was in port and off service with no shore
