Welcome to the website of the MAIB
The Marine Accident Investigation Branch (MAIB) examines and investigates all types of marine accidents to or on board UK ships worldwide, and other ships in UK territorial waters. The sole objective of MAIB accident investigations is to determine the circumstances and causes of the accident with a view to preserve life and avoid accidents in the future, not to apportion blame or liability.
The work of the MAIB
Damaged boat The head of the MAIB, the Chief Inspector of Marine Accidents, reports directly to the Secretary of State for Transport. We have four teams of accident investigators, each consisting of a principal inspector and four inspectors. All are professionally qualified and experienced in the nautical, naval architecture, engineering and/or fishing disciplines of the marine industry. We use this website to share our findings with the public and industry stakeholders, as well as providing a direct means of communication with the MAIB.
