The standard specifically defines technical delivery conditions for hot-rolled weldable steel plates. It is a critical resource for engineers and manufacturers building:

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

: e.g., S355MLO, S420MLO, S460MLO, S500MLO. en 102251 pdf verified

: Infrastructure driven into the seabed.

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 replacing older designations with systemized codes.

: High-strength grades like S550QLO, S620QLO, and S690QLO. Thickness Limitations

The 2019 edition introduced a new naming convention, replacing older designations with systemized codes. 1. Scope and Applications : e.g.

: Plates used as the base material for forming larger structural tubes.
