Intermediate Wind Girder

[napster385]

Hi Everyone,

Is installation of intermediate wind girder on inside of tank permitted by API 650?

It would normally be avoided due to either having a floating roof, or due to the possibility of having one at some point in the future. But I don't see that API prohibits it, either. The wording on the top wind girders says they shall "preferably" be located outside.

If I were to do such a design, I would make sure that the corrosion allowance (if applicable) was applied to all surfaces of the wind girder.

It is not prohibited and it is not that uncommon in extremely high snow areas where falling snow and ice can wipe out girders
