Also, note that Annex V is fairly new, and that the wind/pressure/seismic overturning criteria have been revised with each addendum, so those ratings could vary depending on the year of the standard in use. Title Seismic Assessment of Steel Chemical Storage Tanks in API 650 Welded Steel Tanks for Oil Storage (API , 2007) is most applied. Theoretically, it considers two response modes of a tank and its contents impulsive and convective (Housner, 1963).
