Resumen:
This document specifies requirements for weldable structural steels, in the form of sections (e.g. H-, I-, Z-sections, U-channels, angles and tees) excluding hollow sections, to be used in the fabrication of fixed offshore structures. The thickness limitation in this standard is up to and including 63 mm. For steel qualities with mechanical properties in the transverse direction (named xL1O) sections with flange widths smaller than 180 mm and channels with flange widths smaller than 90 mm cannot be ordered. Greater thicknesses may be agreed, provided the technical requirements of this European Standard are maintained. This European Standard is applicable to steels for offshore structures, designed to operate in the offshore sector but not to steels supplied for the fabrication of subsea pipelines, risers, process equipment, process piping and other utilities. It is primarily applicable to the North Sea Sector, but may also be applicable in other areas provided that due consideration is given to local conditions e.g. design temperature. NOTE This document has an informative Annex C on the prequalification of steels for fixed offshore structures in arctic areas. Minimum yield strengths up to 460 MPa are specified together with impact properties at temperatures down to -40 °C.
