Tanks are designed by a team of engineers with years of experience in the oil industry.The team has a thorough understanding of oil field production storage requirements and using computer assisted design, are able to create specialized plans for tanks that conform to special conditions such as heavy liquids, high wind factors, snow or seismic loadings. Tanks can be configured to meet specific capacity requirements. Size can be increased or decreased by the addition or removal of a ring of tank shell staves. Tanks can be installed on the ground erected on elevated platforms or towers or inside existing buildings.
