— Annex F (Part 1) provides guidance for steels intended for arctic regions.
EN 10225 is the definitive European standard for weldable structural steels in fixed offshore applications. Its four-part structure ensures that every form of steel—from heavy plates to complex sections and hollow sections—meets the demanding requirements of the marine environment. Understanding its grade designations, thickness limits, and mechanical properties is essential for engineers, fabricators, and procurement specialists.
The standard specifies the technical delivery conditions for weldable structural steel plates used in the fabrication of fixed offshore structures . It is primarily applied in the North Sea sector but includes provisions for other regions, such as arctic areas. Core Specifications en 102251 pdf

The standard specifies three main grade families:

EN 10225-1 isolates requirements explicitly for . It operates alongside adjacent parts of the EN 10225 family that regulate other product forms: Part 1 : Steel Plates Part 2 : Sections (Angles, beams, channels) Part 3 : Hot-finished hollow sections Part 4 : Cold-formed hollow sections
Offshore structures experience low ambient temperatures. EN 10225-1 requires mandatory Charpy V-notch impact testing at low temperatures, often at -20°C or -40°C, to ensure the steel remains ductile and does not crack under sudden impact or stress. 4.
