If you have landed on this page searching for the term you are likely an engineer, procurement specialist, or fabricator working in heavy industry. It is highly probable that you are looking for the European standard for offshore structural steels. The correct designation for this standard is EN 10225 – a technical specification for weldable structural steels for fixed offshore structures. Arctic Conditions: Includes an Informative Annex F :
The EN 10225 standard is split into multiple parts based on the product form. .
Use or “BS EN 10225‑1:2019” (for the UK adoption) when searching standards store websites.
: The standard applies to structural components on fixed platforms. It explicitly excludes subsea pipelines, risers, process piping, and pressure vessels.
