  1. Increasing Service-Life of Cut-and-Cover Tanks by Jan Bremert Technical Director Tba International GmbH & Co. KG Fabersweg 1 22848 Norderstedt Germany Phone.: 01149 40 734 4090-11 Fax: 01149 40 523 6081 E-Mail: j.bremert@tankbau.com

  2. Cut-and Cover Tanks of the US Forces mostly built in the 1950s • Single-walled • Corrosion problems • Deformations caused by ground water • Structural damages • Operational problems

  3. Internal corrosion

  4. Damaged bottom weld seam

  5. Deformations in Tank Bottom

  6. Advantages of renewing old tanks • Purchase of new property is not necessary • construction permit is not required • no changes in infrastructure

  7. Additional Advantages of Cut-and-Cover Tanks • no fire protection facilities required • secondary containment outside the tank is not required • less safety distance between the tanks

  8. Leak Protection Lining Primary skin Interstitial space Secondary skin Structural tank

  9. Option 1 • Single-skin Lining • Application on tank bottom and wall • guarantees the tightness of the tank • corrosion protection is included • Used if leak monitoring is not required

  10. Option 2 Double-skin Lining • System is permanently monitored by leak detector device • Highest level of safety and environmental protection • Meets all European government regulations • Is recommended by NATO and USAFE • Has an Equipment Approval from Florida DEP

  11. Pore TestingHigh Voltage Pore Test 1. Sealing with polyester resin High Voltage Pore Test 2. Sealing with polyester resin High Voltage Pore Test

  12. Tank Renovation at Tank Farm Vidin, Bulgaria • Main problems: • Pit corrosion in the tank bottom • Single-skin bottom • Internal support construction for center column

  13. Flexible Manufacturing Integration of pipes

  14. Flexible Manufacturing Integration of columns

  15. Solution for special Constructions Integration of steel constructions on tank bottom

  16. Tank Renovation on US Air Base Incirlik, Turkey • Main problems: • Heavy Corrosion in the tank wall • Pit corrosion in the tank bottom • Corrosion at the tank roof • Tank bottom without slope to the pump sump

  17. US Air Base Incirlik, Tank 3

  18. US Air Base Incirlik, Tank 3 Steel fibre concrete at tank bottom

  19. US Air Base Incirlik, Tank 3 Shotcrete application at tank wall

  20. US Air Base Incirlik, Tank 3 Concrete wall and coating at tank roof and columns

  21. US Air Base Incirlik, Tank 3 tba leak protection lining

  22. New Tank Construction cost: $ 4.5 million Restorated Tank Construction cost: $ 1.5 million Tank Reconstruction

  23. Tank Renovation in Arahal, Spain • Main problems: • Deformations in the tank bottom • Pit corrosion in the tank bottom • Cracks in the welding seams • Heavy corrosion at the tank roof • Tank bottom without slope to the pump sump

  24. Arahal Tank 206 New concrete bottom with leak protection lining

  25. Arahal Tank 208 Just using the existing manholes No additional openings in the tank necessary

  26. Arahal Tank 206 Coating of Tank Roof and Columns

  27. Arahal Tank 206 Final conductive Coating on Tank Bottom and Wall (if required)

  28. Reliable system System with low operation costs Used for more than 40 years in storage tanks acc. to standard design US Air Forces Europe No corrosion problems Long service life tba Leak Protection Lining

  29. Restoration of cut and cover tanks with Leak Protection Lining = An easy and cost-saving Way

  30. Tank retrofitting and reconstruction >>> There is always a solution <<<
