Cherryl Chico, Macario O. II Cordel, Mahinthan Joseph Mariasingham, Elaine S. Tan
TL;DR
This paper introduces a new method to analyze disruptions in maritime passageways using AIS data, showing how events like the Suez Canal blockage affect vessel traffic and routes.
Contribution
A novel framework for analyzing anomalous maritime events using AIS data to quantify impacts and identify new routes.
Findings
The Suez Canal blockage had distinct phases affecting vessel dwell times.
New routes emerged as vessels bypassed the blockage.
The framework was successfully applied to disruptions in the Bosporus and Bab el-Mandeb Straits.
Abstract
Passageways are critical gateways in maritime trade, providing efficient routes for global commerce. This means that disruptions such as natural disasters or human error at these crucial points can significantly impact numerous economies across various facets of trade. Thus, real-time monitoring of such events and their impact on different vessel types is crucial for developing timely mitigation strategies, policies, and penalties. This paper proposes a novel framework for analyzing anomalous events in passageways using Automated Information System (AIS). This framework enables monitoring of affected vessels and quantifies the impact in terms of the number of vessels, dwell and idle times, and the emergence of new routes. To demonstrate its potential, we applied the proposed framework to the Suez Canal blockage in March 2021. Results revealed distinct phases during the event, with each…
