The modular approach to emergency power fueling
In
recent years Belly tanks, also called Subbase fuel tanks, have gained popularity with respect to
emergency power fueling systems. Belly tanks are steel fuel tanks
with a generator bolted on top. In emergency power refueling
systems, however, simplicity in design is not always the best
route. A generator set mounted on top of the tanks is subject to major vibration and in some cases lead to a failure of the belly tank at
the weld seams. A failure of the Belly or Subbase tank can become a major environmental, logistical and financial
nightmare. Generator sets must be taken off-line, removed with a
crane, repaired and then placed back into place. Because of the
stress caused by vibration most belly tanks only come with 1 a
year warranty (as opposed to a 20 or 30 year warranty with a ConVault
aboveground storage tank). In addition, with many Subbase fuel
tanks a visual inspection of the entire unit is not possible which may
be a code violation (consult your local fire authority).
A
modular (and very common) approach to emergency power fueling uses a
standalone main tank along with a smaller day tank connected to the
generator system. This approach assures that neither tanks are
affected by the vibration of the generator. Should a repair be
needed, a temporary tank can be piped in to the existing piping while
the original tank is repaired and the generator set does not need to
remain off-line for more than a few minutes.
