Question:

What specific conditions apply to the vessel "Empty" case?

Answer:

COMPRESS treats the "Empty" condition as follows:

• Internal pressure = 0 psi [0 kPa]
• Operating liquid = none
• Wind = full wind as determined by selected Code
• Seismic = full seismic as determined by selected Code
• Temperature = 0° F [-17.78° C] (ambient temperature range)
• Allowable stresses = based on ambient temperature range (0°-100° F) [-17.78° - 40° C]
• Required thickness for vessel components are reported for both new and corroded conditions.
• Skirt and Base Ring calculations are reported for both new and corroded conditions.
