EN 14015 addresses the design and construction of the following tank elements:
The standard is under continuous review by CEN/TC 265 (Steel storage tanks). Future revisions are expected to address: En 14015 Pdf
❌ – 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 addresses the design and construction of
Specifies the steel grades, plate thicknesses, and allowable stresses required to handle liquid pressure and environmental loads (wind/snow). ❌ Floating roofs – Only briefly referenced; you’ll
“EN 14015 is a competent, Eurocode-based tank standard well suited for above-ground, ambient temperature liquid storage in Europe. It is simpler than API 650 for small-to-mid sized tanks but lacks detailed provisions for seismic, floating roofs, and moderate pressure. For a purely European project without high seismic risk or internal pressure, it’s a solid, enforceable specification.”
API 650 is widely regarded as the global standard for the oil and gas industry, utilizing Imperial units (inches and feet) and focusing heavily on American material grades. EN 14015, conversely, is metric and is harmonized with European material standards (Eurocodes). One significant divergence is the treatment of hydraulic testing. EN 14015 allows for specific alternative testing methods, such as vacuum box testing for tank bottoms, which can offer time savings during construction. Furthermore, EN 14015 is often viewed as providing more explicit guidance on seismic design for specific European ground conditions compared to the broader approaches found in API codes. For companies operating within the European Union or dealing with European engineering firms, compliance with EN 14015 is not just a choice but often a regulatory requirement.
