EN 10225-1:2019 is the European standard specifying the technical delivery conditions for weldable structural steel plates used in the fabrication of fixed offshore structures. It provides a rigorous framework for high-strength steels designed to withstand the harsh environmental conditions typical of the North Sea and similar offshore sectors. Scope and Application
EN 10225-1:2019 defines technical delivery conditions for weldable structural steel plates used in fixed offshore structures, covering grades from normalized S355NLO to quenched & tempered S690QLO. The 2019 revision introduces stricter requirements, including higher strength grades and specific guidance for Arctic service, with mandatory EN 10204 3.1 certification.
