Research on big data has been actively studied to utilize a wide range of data in various fields. In recent years, researches on collection, processing and analysis of big data for ship design, maintenance and repair have been conducted in shipbuilding and marine fields. In particular, collection, processing and analysis of big data is an important technology for diagnosing the condition of the ship and improving its performance and energy efficiency, but this research is in the early stage and has not been done systematically. Accordingly, in this study, major technologies and handling methods of big data in shipbuilding and marine fields were studied. The latest technology on ship-related big data was introduced for development of a smart ship, which is a next generation ship that can monitor, remotely diagnose and control various navigation information, and future research direction associated with big data was presented.
