This study investigates how international organizations, International Maritime Organization (IMO) member states, and associate members have embarked on maritime management (MM) measures to address dire situations in the context of the COVID-19 pandemic. It explores the evolution of MM practices from international organizations, IMO member states, and associate members to ensure the resilience and sustainability of the shipping industry. Corpus linguistics was employed as a computer-assisted method to assess a large number of naturally occurring texts. Circular letters from international organizations and member states listed on the IMO website from January 2020 to July 2021 were curated and built into three corpora. Through corpus linguistic analysis of circulars from three different crisis phases (Pre-/early-crisis, Crisis in progress, Post-COVID-19 crisis phase), we discovered an MM progression mechanism developed between stakeholders in conjunction with the post-crisis period. The study presented the “MM-as-process” vision to emphasize the time-varying dynamic nature of MM development during the disruption.
