US$20 000. A trained crew is sent out with
confined space entry equipment and an
inspector is lowered into and alongside the
silo, typically from the roof.
Level three
At this top tier the same exterior and interior
inspections occur, but with additional expertise
on the ground. This is achieved by including
a silo design engineer onsite for analysis and
written recommendations. The range in cost is
widest at this level, at between US$12 000 and
US$30 000, depending on the number of silos
needing inspection and the scope of needs that
require attention.
Through clear communication with the
specialised inspector on a consistent
schedule, both cost and severity factors can
be taken into account when planning the next
appointment. In all three inspection options,
recommendations for repairs and remediation
are provided if warranted. But the key to
having credible recommendations is to have a
specialised inspector or silo design engineer
involved in the project.
Typically, an inspection looks at the
foundations for deterioration or settlements.
In addition, inspectors look at the silo walls
to make sure they are structurally sound
and can withstand the pressures placed on
them for both vertical and horizontal loads
(horizontal loads are an often underestimated
component). Looking at the silo roof structure
is also important because this can become a
problematic issue. An inspection ensures that
it is operating correctly and that there is no
potential for collapse into the silo.
After this, another investigation focuses on
what is holding the stored material from the
bottom. Whether it be a flat-bottom silo or a
cone-bottom silo, whatever structure is in the
bottom of the silo is also subject to a large
vertical gravity load. This structure is affected
by material side pressures pushing out on the
structure and how it ties into the wall.
Budget
But how does a facility manager or silo owner
protect the company pocketbook and still
responsibly maintain the silo? With regular
planning and by scheduling routine inspections
on rotation, an owner can minimise the need
for remediation while also keeping expert eyes
on preventative maintenance needs.
