Industrial storage tanks are critical assets for the oil, gas, chemical, and water treatment industries. Ensuring their structural integrity, safety, and longevity requires strict adherence to standardized engineering practices. In Europe and many international markets, the definitive standard for this engineering sector is EN 14015.
The tank shell must withstand hydrostatic pressure from the liquid inside, as well as wind and seismic loads. EN 14015 utilizes specific calculation methods (like the variable design point method or the one-foot method) to determine the minimum allowable thickness for each shell course (ring). 3.

Requirements cover carbon steel and various grades of stainless steel (including Duplex) to ensure corrosion resistance and durability.
❌ – Limited to low internal pressure (≤ 50 mbar). For higher pressure, use EN 13445. ❌ Refrigerated storage – Excludes fully refrigerated LNG/ethylene tanks (use EN 14620). ❌ Seismic – References Eurocode 8 but lacks detailed tank-specific seismic detailing (API 650 Appendix E is more comprehensive). ❌ Aging – Published 2004, no active amendment for newer materials (e.g., thermomechanical steels). ❌ Floating roofs – Only briefly referenced; you’ll need API 650 Appendix H or ISO 28300 for details. EN 14015 utilizes specific calculation methods (like the
