Weldable structural steels for fixed offshore structures - Technical delivery conditions - Part 1: Plates

This document specifies requirements for weldable structural steels, in the form of plates, to be used in the fabrication of fixed offshore structures.
The following thickness limitations are given in this standard:
- S355NLO up to and including 200 mm;
- S355MLO, S420MLO, S460MLO, S500MLO up to and including 120 mm;
- S420QLO, S460QLO, S500QLO, S550QLO, S620QLO, S690QLO up to and including 150 mm.
Greater thicknesses can 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, including plate for structural hollow sections (see EN 10225-4). It does not apply to plates 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 F on the prequalification of steels for fixed offshore structures in arctic areas.
Minimum yield strengths up to 690 MPa are specified together with impact properties at temperatures down to -40 °C.

- S420QLO, S460QLO, S500QLO, S550QLO, S620QLO, S690QLO bis zu 150 mm.
Größere Dicken können vereinbart werden, vorausgesetzt die technischen Lieferbedingungen dieser Europäischen Norm werden eingehalten.
Diese europäische Norm gilt für Stähle für Offshore-Konstruktionen, die für den Offshore-Einsatz vorgesehen sind, einschließlich Bleche für Hohlprofile (siehe EN 10225-4). Sie gilt jedoch nicht für Stähle zur Herstellung von Unterwasserpipelines, Steigleitungen (risers), Verfahrens-Ausrüstungen, Rohrsystemen und anderen Einrichtungen und Ausrüstungen. Sie gilt in erster Linie für den Bereich der Nordsee, kann jedoch auch für andere Gebiete angewendet werden, vorausgesetzt, dass die örtlichen Bedingungen, z. B. die Auslegungstemperatur, genügend berücksichtigt werden.
ANMERKUNG Dieses Dokument hat einen informativen Anhang F bezüglich einer Vorqualifizierung von Stählen für den Einsatz in arktischen Gebieten bei Offshore-Konstruktionen.
Mindestwerte der Streckgrenze bis zu 690 MPa werden zusammen mit Werten für die Kerbschlagarbeit bis herunter zu Temperaturen von -40 °C angegeben.

Aciers de construction soudables destinés à la fabrication de structures marines fixes - Conditions techniques de livraison - Partie 1 : Tôles

Le présent document spécifie les exigences applicables aux aciers de construction soudables destinés à
la fabrication de structures marines fixes sous forme de tôles.
Les limites d'épaisseur suivantes sont données dans la présente norme :
- S355NLO jusqu'à 200 mm inclus ;
- S355MLO, S420MLO, S460MLO, S500MLO jusqu'à 120 mm inclus ;
- S420QLO, S460QLO, S500QLO, S550QLO, S620QLO, S690QLO jusqu'à 150 mm inclus.
Des épaisseurs plus importantes peuvent être convenues par accord, à condition que les exigences
techniques de la présente Norme européenne soient respectées.
La présente norme s'applique aux aciers pour constructions marines exploitées sur le domaine maritime
européen, y compris les tôles pour les profils creux soudés formés à froid (voir l'EN 10225‐4). Elle ne
s'applique pas aux aciers fournis pour réaliser des oléoducs sous‐marins, conduites montantes,
équipement de procédés et autres tuyauteries de transport. Elle s'applique prioritairement au secteur de
la mer du Nord mais elle peut également s'appliquer dans d'autres zones dans la mesure où les conditions
locales sont dûment prises en compte, notamment la température de conception.
NOTE Le présent document comporte une Annexe F informative sur la présélection des aciers destinés à la
construction de structures marines fixes dans les zones arctiques.
Les limites d'élasticité jusqu'à 690 MPa sont spécifiées ainsi que les énergies de rupture en flexion par
choc à des températures jusqu'à - 40 °C.

Konstrukcijska jekla za varjene konstrukcije naftnih ploščadi - Tehnični dobavni pogoji - 1. del: Plošče

Ta del standarda EN 10225 določa zahteve za variva konstrukcijska jekla v obliki plošč, ki se uporabljajo za izdelavo konstrukcij naftnih ploščadi.
V tem standardu so podane naslednje omejitve debeline:
– S355NL1O do vključno 200 mm;
– S355ML1O, S420ML1O, S460ML1O, S500ML1O do vključno 120 mm;
– S420QLO, S460QLO, S500QLO, S550QLO, S620QLO, S690QLO do vključno 150 mm.
Dogovori za večje debeline so mogoči, če se ohranijo tehnične zahteve tega evropskega standarda.
Standard velja za jekla za konstrukcije naftnih ploščadi, projektirane za delovanje v priobalnem območju, vendar ne za jekla, dobavljena za izdelavo podmorskih cevovodov, dvižnih cevi, procesne opreme, procesnih cevovodov in drugih sredstev. Uporablja se predvsem na območju Severnega morja, lahko pa se uporablja tudi na drugih območjih, če se ustrezno upoštevajo lokalni pogoji, npr. temperatura.
OPOMBA:   Na voljo je dodatek F o predizbiri jekel za konstrukcije naftnih ploščadi v arktičnih območjih.
Minimalne napetosti tečenja do 690 MPa so določene skupaj z nizkotemperaturnimi lastnostmi pri temperaturah do –40 °C.
