It is crucial to distinguish EN 10225 from its more common counterpart, EN 10025, which governs structural steel for onshore construction (such as buildings and bridges). While both standards deal with structural steel, EN 10225 imposes significantly stricter requirements. The rationale is that while a failure in a building might result in localized damage, a failure on an offshore platform can lead to catastrophic environmental disasters, loss of human life, and immense financial costs. Therefore, EN 10225 is designed to ensure "fitness for purpose" in a zone where maintenance is difficult and failure is not an option. en 102251 pdf
