This article aims to identify themes and trends of global offshore industry research by examining 800 papers collected from international journals through incorporation of corpus and language network keyword network analysis. Themes and trends are discussed with important keywords representing each giant component of four five-year periods from 1995 to 2014. We visualized keyword networks based on the whole keyword nodes belonging to each giant component drawn by using degree centrality. We tried to explore how the important keywords have changed over time and what the recent important keywords are. The paper shows that frequency of keywords is subject to Zipf's law and degree distribution of keyword nodes also exhibits power law. Therefore keyword network analysis used in this paper will be useful to identify and understand themes and trends of global offshore industry research because of some patterns of important keywords by year as well as the visual connection between important nodes in giant components.
