Determining Tilt in Tanks Used to Store Oil and Oil Products During Hydraulic Testing and Operation

Resumo

Requirements stated in regulatory documents are discussed with respect to determining deformations in beds of vertical steel cylindrical tanks used to store oil and oil products. A procedure is proposed for determining tilt in the foundation and the tank proper, based on the aggregate settlement of deformation markings on the foundation and points along the bottom edge. A computer program was developed to calculate tilt. An example is presented of determining settlement and tilt for a pile foundation of a vertical steel tank after 5 years of operation.
