The Red Sea Under The Microscope: A Deep Dive Into Suez Canal Rerouting And Its Consequences
Pre-Crisis Traffic:
Initially, 667 vessels were identified traversing the Suez Canal within their respective trade lanes.
Post-Crisis Traffic:
Subsequently, a separate group of vessels navigating near the Cape of Good Hope after the crisis was identified.
Rerouted Vessels:
Notably, a subset of vessels that previously used the Suez Canal neither continued through the Suez nor switched to the Cape of Good Hope, allowing us to safely assume these vessels were likely rerouted via the Cape of Good Hope.
As a result of these analyses, we estimate that a total of 825 vessels have been rerouted through the Cape of Good Hope. To meet the capacity needs within these specific trade lanes and to maintain Schedule reliability, the number of extra vessels assigned by Carriers on the same Lanes was 158, which can also be translated to a notable 23% increase in vessels.
This adjustment in shipping routes indicates a dynamic response within the maritime industry to maintain operational efficiency in the face of unforeseen disruptions.
Deeper analysis of significant factors:
Speed increases
Focusing on the average speed of the vessels before and after the crisis began, we identified that vessels were steaming with an average speed of 13.67 knots. In contrast, after the crisis occurred, rerouting via Cape of Good Hope, vessels were steaming with a speed of 15.87 knots.
Deviations in speed may impact fuel consumption in a non-linear manner and, consequently, emissions from the vessel. In this case, the speed variance between the two observation periods significantly increases fuel consumption and total emissions.
Hence, it is safe to assume that the speed increases effected by Carriers were used to partially “compensate” for the increase in additional distance due to the rerouting. An average speed increase of 16.1% was identified.
Distance increases post-crisis
In addition to the augmentation in the average vessel speed, it is imperative to address the increase in the distances these vessels were required to traverse due to the circumstances arising in the Suez Canal. More specifically, our data indicated that the average percentage of increase in distance was over 40% after rerouting.
Vessel utilization factor increases
Utilization factors are a significant parameter we observed as they can impact the emissions allocated to each cargo shipped. The utilization factor is the loaded container ratio to the total container slots available on a vessel.
Higher utilizations lead to lower emissions assigned to one cargo unit (e.g., TEU). Our analysis reveals that the utilization factor stood at 61% and 63% before and after the crisis, respectively.
VesselBot's mission is to precisely navigate this complex interplay between speed, distance, and cost implications, enabling informed decision-making and strategic optimization in the face of evolving maritime scenarios.
Emissions increase
The paramount consequence of the Red Sea incident lies in a substantial escalation of emissions. In light of the imperative to minimize the environmental impact, the Red Sea incident underscores a significant surge in emissions.
To delve into numbers, before the crisis, the emission levels were recorded at 8,959,335 tons of CO2; following the incident, they rose to 15,324,375, revealing a staggering 71% increase in emissions post-crisis.
This environmental impact underscores the need for strategic actions to mitigate emissions, emphasizing technology's critical role in measuring, addressing, and reducing them.
