Petroleum and Chemical Storage Tanks - page 62

The storage tank and saddles must
be designed to accommodate loads
resulting from the weight of the tank
and its contents, external equipment
and environmental conditions. In areas
subject to damaging wind, water
or earthquakes, the design of the
supporting structure and connections
for the storage tank shall require
special engineering consideration.
The design and construction of tank
supports and foundations is critical
and should only be undertaken and
supervised by competent professionals.
Note:
1. Do not rely on tack or seal-welded saddles
as a means for securing a tank in flood-prone
areas. A hold-down system, connected to a
adequately sized anchor pad, is recommended.
2. A properly designed hold-down strap system
with adequately sized reinforced concrete
hold-down pad is recommended to secure
a tank in flood-prone areas.
