The maritime industry, Similar to many other sectors, is adopting Industry 4.0. The implementation of Industry 4.0 presents significant advantages to the marine industry including, creating new value, fostering cooperation between port actors, and reducing operational costs. This paper analyzes the most intellectual structure of Industry 4.0 and maritime research. To identify the main clusters of this research, a document co-citation analysis was applied. Furthermore, the trend of total publications, the most cited authors, Geographical distribution, and cooperation of countries of this domain was analyzed with the help of CiteSpace and Histcite Software packages. The data collected for bibliometric analysis were collected from the web of Science from 2011 to 2021. The results reveal that the number of publications in Maritime 4.0 has significantly increased since 2011 and will continue to grow rapidly in the next few years. Regarding the Geographical Distribution of Publications in the research domain, such publications primarily originate from People R China, the USA, and Italy. According to document co-citation analysis, Digitalization, Artificial intelligence, and Blockchain are the most active clusters of maritime 4.0 research.
