: e.g., S355MLO, S420MLO, S460MLO, S500MLO.
To ensure reliability in harsh seas, EN 10225-1 mandates rigorous quality controls: Weldable Structural Steels for Offshore | PDF - Scribd
The standard is the definitive European specification for weldable structural steel plates used in the fabrication of fixed offshore structures. This standard ensures that steel materials can withstand the extreme mechanical stresses and corrosive environments of sectors like the North Sea. 1. Scope and Applications
: Primary structural components that support topsides.
The 2019 edition introduced a new naming convention, replacing older designations with systemized codes.
The 2019 update significantly increased the maximum allowable thicknesses for various grades: : Up to 200 mm . MLO (Thermo-mechanical) : Up to 120 mm . QLO (Quenched & Tempered) : Up to 150 mm . 3. Key Requirements and Testing
: High-strength grades like S550QLO, S620QLO, and S690QLO. Thickness Limitations
: This standard does not apply to subsea pipelines, risers, or process piping. 2. Technical Specifications & Steel Grades
Grades are categorized by their delivery condition and yield strength: : e.g., S355NLO (yield strength of 355 MPa).
: Plates used as the base material for forming larger structural tubes.
