SOLAS Convention, as the most important international maritime treaty regulating ship safety, sets up the minimum safety levels for construction, equipment and operation. Due to the development of technology, safety understanding and management, all three safety standards are undergoing revision over time. This paper aims to explore and explain the trend of these changing standards by employing a keyword analysis on SOLAS Convention based on the idea that keywords are indicative of changes in writing style, which can ultimately be linked back to social change. To achieve this objective, five consolidated versions of SOLAS Convention covering the period from 1974 to 2015 were targeted to collect data. Keywords of three safety standards in each version were extracted respectively using WordSmith tools. For discovering the degree of diachronic changes in each safety standard, statistical measures like frequency count and type-token ratio were adopted to compare the lexical distribution and density of each keyword list. The findings suggest that all three safety standards have been revised over time and the changes vary in terms of degree and content. This study is believed to be useful for understanding the safety concerns in maritime industry and to contribute to the literature in the diachronic research conducted by keyword-based approach.
