The Danish Maritime Accident Investigation Board (DMAIB, Danish: Den Maritime Havarikommission) is the maritime accident investigation agency of Denmark, headquartered in Valby, Copenhagen. It is an agency of the Ministry of Business and Growth Denmark.
Previously the Danish Maritime Authority's Division for Investigation of Maritime Accidents investigated maritime accidents. A European Union directive asks countries to establish maritime investigation authorities that are independent of the maritime administration divisions. The bill L xx will cause Denmark to establish a new maritime investigation agency.
