Element Study

An internal floating roof is to be installed on an existing large API storage tank. In order to ensure the proper functionality of the roof, the deformation of the shell has been monitored and analysed. The measurements on the shell ovality show that the actual radial deformation is beyond the acceptable limit for installation of a serviceable internal floating roof and corrective actions should be taken. Consequently, a series of tests and analyses were performed to provide a recommended practice to restore the tank to its round shape.
