Analysis of the impact of Suez Canal blockage on the global shipping network

This study aims to quantitatively analyze the impact of the Suez Canal blockage on global maritime transportation networks. The Suez Canal, a critical global maritime transport route, experienced a significant disruption due to a ship grounding accident in March 2021, exposing the fragility of global logistics supply chains. We constructed a comprehensive shipping network, integrating real trajectory data from automatic identification system (AIS) devices on ships collected in 2018. The network comprises 2713 nodes and 137,830 links, with defined targeted (Suez Canal blockage) and random attack modes. Our analysis, based on multiple network topology metrics, reveals that the blockage had a considerable effect on the global shipping network, significantly more than random disruptions of comparable scale. The incident led to a decrease in network accessibility and connectivity, conforming to the law of distance attenuation. The effects varied across continents; Africa experienced the most significant impact, while Asia and Europe were less affected. Europe's developed transport system effectively mitigated the impact. Data on different ship types passing through the Suez Canal showed that container ships and petrochemical tankers were the most affected. This research underlines the Suez Canal's significance to global shipping and the necessity of robust supply chain management strategies to limit the fallout from similar future incidents.
