The MAIB investigates marine accidents involving UK vessels worldwide and all vessels in UK territorial waters.
Our job is to help prevent further avoidable accidents from occurring, not to establish blame or liability.
Marine Accident Investigation Branch receives between 1500 and 1800 reports of accidents of all types and severity each year. On average this leads to 30 separate investigations being launched.
Who we are
