amount of site wiring.
A very distinct advantage of the packs
is flexibility and Gansbaai Marine is a
typical example. Previously, if something
went wrong with the system, the entire
plant would shut down and the operation
would stand still. Now, because the four
packs are independent systems, if one
shuts down, the rest can still operate as
normal, preventing any loss of production.
