Wind blowing on the ODU will subject the mounting structure to significant lateral force. The magnitude of
the force depends on both wind strength and surface area of the ODU. Wind loading is estimated using the
following formulae:
l
Force (in kilograms) = 0.1045aV
2
where:
l
“a” is the surface area in square meters, and “V” is the wind speed in meters per second.
l
Force (in pounds) = 0.0042Av
2
l
where:
o
“A” is the surface area in square feet, and
o
“v” is the wind speed in miles per hour.
Applying these formulae to the 450 platform at different wind speeds, the resulting wind loadings are
shown in below tables.
