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.

Offshore steels must remain ductile even in freezing arctic or sub-sea temperatures. EN 10225-1 requires mandatory Charpy V-notch impact testing, often conducted at temperatures as low as or -50°C . The steel must absorb a specific minimum amount of energy (measured in Joules) to prove it will not suffer catastrophic brittle fracture. 3. Through-Thickness Ductility (Z-Testing) en 10225-1 pdf
