Storage tank Inspection and Certification Services
Storage tank is an asset that deserves attention. These tanks can be fabricated of metal, either field erected or shop-fabricated, or non-metallic materials, such as polyethylene or fiberglass-reinforced plastic (FRP). They can be used to store petroleum products, chemicals or waste materials. The field of storage-tank inspections comprises both in- and out-of-service inspections of vertical and horizontal storage tanks, both above and below ground.
A combination of techniques are used to provide a comprehensive condition report on the overall tank floor, shell, roof and structure, including engineering calculations in accordance with API 653 & 650 and other relevant specifications.
