Tank Services

Tank Life Extension
Oil Refinery Tank Life Extension Program

• Floating roof (IFR and EFRs) and aluminum dome roof engineering
• Create innovative solutions for stairs that reduces the amount of welding on an insulated tank shell, which decreases the amount of potential corrosion areas on insulated tank shells.
• Designed and installed new roof platforms that are fully supported by the shell, which requires less inspection and repair/reinforcement on the tank roof.
• Local full time support with specialists from across the country.
• Site support engineering
• Document management
• Pre-qualification of manufacturers and recommendation
