EN 10225-1 is the European standard that specifies the technical delivery conditions for weldable structural steel plates used in the fabrication of fixed offshore structures.
The current version, EN 10225-1:2019, replaced the previous unified EN 10225:2009 standard, which was split into four separate parts based on product form. As an essential document for engineers and offshore fabricators, it ensures materials can withstand extreme marine environments, including low temperatures, corrosive saltwater, and high dynamic loads from wind and waves. Scope and Key Applications
This standard applies specifically to plates for fixed offshore structures like oil rigs, wind turbine foundations, and marine terminals. It is primarily designed for the North Sea sector but is used globally, provided local conditions like design temperatures are considered.
Applicable to: Fixed offshore platforms, jackets, topsides, piles, and plates for structural hollow sections.
Not applicable to: Subsea pipelines, risers, process equipment, or process piping. Technical Requirements and Steel Grades
The standard specifies high-strength steel grades with yield strengths up to 690 MPa and guaranteed impact properties at temperatures as low as -40 °C. Common Steel Grades and Designations
The 2019 edition updated steel names to align with EN 10027-1. S355NLO: Normalized or normalized rolled. S420MLO, S460MLO, S500MLO: Thermomechanically rolled (+M). S420QLO to S690QLO: Quenched and tempered (+Q). Thickness Limitations
Default thickness limits have increased in the 2019 version: Steel Grade Type Maximum Thickness (mm) S355NLO MLO Grades (S355–S500) QLO Grades (S420–S690) Key Changes in the 2019 Edition
The transition from EN 10225:2009 to Part 1:2019 introduced several critical updates:

I notice you're looking for a PDF of the standard EN 10225-1. However, I cannot draft or provide the full text of this copyrighted standard. EN 10225-1 is a technical specification for weldable structural steels for fixed offshore structures (part 1: plates).
What I can do instead:
Help you find a legal source – You can purchase the official PDF from national standardization bodies like BSI (British Standards Institution), DIN, or CEN members, or from platforms like ANSI Webstore or IEC Webstore.
Summarize the scope – EN 10225-1 specifies requirements for thermomechanically rolled (TM) and normalized (N) steel plates for offshore structures, including chemical composition, mechanical properties, and toughness grades (S355, S420, etc.).
Draft a document request – For example:
"I need to purchase a copy of EN 10225-1:2019 – Weldable structural steels for fixed offshore structures – Part 1: Plates. Please provide a quote for the PDF version." Chemical Composition : The standard specifies the chemical
Guide you to a summary – If you need technical data (e.g., yield strength, Charpy V-notch values), I can provide a general overview without copying the standard.
Let me know how I can assist legally and helpfully.
The EN 10225-1:2019 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 and includes considerations for arctic conditions. Table of Contents Overview
The document structure typically follows the standard European (CEN) format for technical delivery conditions: EN-10025-1-2004.pdf - Regbar Construction
EN 10225-1 is a European Standard that specifies the technical delivery conditions for weldable structural steels used in the construction of fixed offshore structures. These structures include oil and gas platforms, wind farms, and subsea infrastructure. The standard is critical for ensuring material integrity in harsh environments where high strength, toughness, and weldability are paramount for safety and operational longevity.
Unlike general construction steel, offshore steel must be welded in challenging conditions without developing cracks or losing strength in the heat-affected zone (HAZ). EN 10225-1 imposes strict controls on chemical composition—particularly Carbon Equivalent (CEV)—to ensure the steel can be welded efficiently and safely.
