Research Hotspots and Trends of Maritime Emergencies in China -A Bibliometric Analysis Based on CiteSpace

This paper aims to identify the hotspots and trends in the study of maritime emergencies. A total of 2,531 articles and journals with relevant topics of maritime emergency published on national knowledge infrastructure (CNKI) between 2002 and 2021 were selected as data for analysis. By analyzing the science mapping generated by CiteSpace, we explored some hidden relationships concerning authors, institutions, and keywords. The results indicate that the scope of research on maritime emergencies has almost reached saturation, but the depth of research is digging. Although a few small author-cooperation groups have been revealed on the map, no core group formed yet. The leading subjects of maritime emergencies are ships and offshore platforms. The common types of accidents are collision, ship-grounding, fire, and oil-spilling. The research foci may gradually shift from relief to monitoring and prevention. Artificial intelligence technology can impact the domain of maritime emergencies. Numerical simulation is an important technological means for scholars.
