The MAIB is a branch of the UK Department for Transport that investigates marine accidents. It has four teams of experienced accident investigators from fields like navigation, engineering, and fishing. The MAIB's role is to determine accident causes to reduce future risks, without apportioning blame. Accidents must be reported quickly to allow evidence collection before decay. MAIB inspectors then assess each accident and may launch investigations. Findings are published through bulletins, flyers, and a biannual digest to spread safety lessons.
