NEED TO KNOW
Fire exposure can degrade steel strength and toughness, increasing the risk of brittle behaviour or loss of strength.
An accurate post‑fire assessment requires hardness testing (ASTM A370) and, when needed, destructive testing, to determine whether steel grade downgrading or structural repairs are necessary.
DNV provides rapid emergency and post‑fire support, including strength assessments and drone based surveys for quick, safe evaluations.
Fire incidents on ships rank among the most frequent accidents, and in recent years, fire incidents have specially increased among container and ro-ro cargo/passenger ships. DNV has supported many cases of post-fire structuraland material assessments, and this news aims to share our insights from this work.
