It plays a vital role in global resource allocation. Ports are an essential part of the global maritime trade. The paper has the potential to provide a reference for port management and improving port navigation efficiency in the post-pandemic era. Accordingly, the relevant improvements and countermeasures are proposed to reduce the adverse impact of the epidemic on the port navigation system. And the density of ships increases in the port area in 2020. The results show that the average anchoring time and berthing time increase by 62% and 11% for cargo ships and by 112% and 63% for oil tankers after the outbreak of COVID-19 compared with that before COVID-19. Finally, a case study is carried out on vessels in the Beibu Gulf, China, operating from 2019 to 2020. The port congestion caused by COVID-19 is quantified by accounting for the number of visiting ships and their residence time. Then, the diversity in vessel anchoring and berthing time are analyzed, reflecting the impact of COVID-19.

Firstly, a ship travel behavior-based model is proposed to identify the vessel anchoring and berthing. To explore the impacts of COVID-19 on ship visiting behaviors, a framework is proposed to analyze the impact of COVID-19 on port traffic using Automatic Identification System (AIS) data. In the maritime sector, trade volume slumped by 3.8% in 2020 compared with 2019.
