After nearly two years of disruption, the Suez Canal is once again welcoming large vessels. While the canal was never officially closed, the impact of the last two years felt very much like a shutdown for many shipping operators who were forced to reroute their vessels thousands of miles off course.
The disruption began in late 2023, when escalating attacks on commercial ships in the Red Sea—particularly near the Bab el-Mandeb strait—made the southern approach to the Suez Canal increasingly dangerous.
As the security situation deteriorated, major carriers opted to avoid the region entirely. This triggered a massive diversion of traffic, with hundreds of vessels rerouted around the Cape of Good Hope. At the height of the crisis, canal transits dropped by nearly half, and the Suez corridor effectively lost its role as the primary east-west shipping artery.
Today, with improved security conditions and renewed confidence among carriers, large vessels are gradually returning to the Suez Canal. This reopening of the world’s most strategic waterway brings much-needed relief to global supply chains.
What the return of the Suez Canal means to ports
During the period of heightened Red Sea insecurity, many carriers diverted vessels around the Cape of Good Hope. This added 10–14 days to transit times, reshaping sailing schedules and undermining the predictability that ports rely on for berth planning and resource allocation.
Ports that typically handled dense Asia-Europe rotations suddenly faced an irregular mix of delayed arrivals, bunching, and vessel gaps. Now that major services are returning to the canal, operators can regain the scheduling stability needed to optimize operations.
More predictable transit times allow ports to manage better berth allocations, quay crane deployment, yard planning, and labour scheduling. Reduced volatility also minimizes bottlenecks caused by multiple delayed vessels arriving at the same time.
Ports can once again align equipment usage with expected volumes, lowering idle time and improving asset productivity. For terminal operators, this translates into higher throughput efficiency—and in many cases, better service levels for shipping lines seeking reliable turnaround times.
The environmental implications are equally significant. During the disruptions, the long detour around Africa led to dramatic increases in fuel consumption and emissions. Port calls became more erratic, creating energy-intensive peak periods at terminals, while inland logistics networks had to respond to unpredictable arrival patterns. The return of Suez traffic helps reverse these trends.
What the return of the Suez Canal means to vessel owners
For vessel owners specifically, the return of the Suez Canal brings renewed predictability, improved cost structures, and opportunities to optimize fleet deployment.
One of the most immediate benefits is the restoration of schedule reliability. The elongated voyages around Africa required owners to adjust charter arrangements, reposition vessels, and cope with cascading delays across their networks.
Now, predictable routing through Suez allows for tighter control over vessel cycles, enabling owners to maintain steadier capacity deployment and reduce the ripple effects of late arrivals. The ability to forecast vessel availability more accurately enhances chartering strategies, whether through optimizing long-term contracts or gaining flexibility in short-term charters.
Cost efficiency also improves substantially. The Cape diversion sharply increased bunker consumption, putting upward pressure on operational expenditure and emissions. With the return to the Suez route, owners can benefit from shorter transit distances, resulting in lower fuel consumption and reduced wear on engines and other onboard systems.
From an environmental standpoint, the return to Suez is significant. The extended voyages around Africa generated significantly higher CO₂ emissions per rotation. Reestablishing the shorter route directly supports the industry’s emissions-reduction initiatives by lowering the carbon intensity of voyages. Vessel owners can now more effectively align their operations with CII ratings, EU ETS requirements, and other regulatory frameworks
The logistics landscape also becomes more manageable for vessel owners. With a stabilized Suez route, vessel turnaround times can normalize, improving asset utilization and reducing the risk of unplanned delays. Better coordination among ports, terminals, and inland carriers enhances end-to-end efficiency—a key advantage in a market where operational precision directly translates into financial performance.
Optimisation is still important
Strategically, the return of Suez traffic allows vessel owners to resume long-term planning with greater confidence. Decisions around fleet expansion, retrofits, alternative fuel investments, and new service designs all depend on the stability of major trade corridors. Ports and terminal operators also stand to benefit through improved efficiency, reduced uncertainties, lower emissions, and a re-energized logistics ecosystem.
That said, some underlying supply chain issues persist.
Ports and vessel owners continue to operate in a highly complex and unpredictable environment where real-time situational awareness remains essential. While the resumption of Suez traffic improves routing efficiency, the broader maritime risk and operational landscape still require constant monitoring, intelligence, and data-driven decision-making.
Geopolitical tensions, piracy threats, and AIS manipulation have not disappeared. Ports still need tools to provide critical real-time insights that help operators assess threat levels, identify suspicious vessel behaviour, and navigate high-risk zones safely.
There is also the issue of congestion at key chokepoints. Ports and owners must manage clustering, bottlenecks, and fluctuating arrival times as schedules normalize. Operators still need to accurately forecast congestion, optimize arrival windows, and coordinate port calls more efficiently to reduce waiting times and operational inefficiencies.
Finally, while the shorter Suez route reduces emissions compared with diversions around Africa, vessel owners are simultaneously facing tighter carbon-intensity regulations and new reporting requirements. Tracking fuel consumption, optimizing routing, and providing the emissions data needed to remain compliant is still a must.
As the industry transitions back to higher traffic volumes and evolving regulatory expectations, real-time visibility offered by tools like OCIANA remains critical.
Why OCIANA® is a must-have tool
GSTS’s OCIANA® platform provides ports and vessel owners with an integrated suite of decision-support capabilities grounded in advanced data analytics, artificial intelligence, and real-time information processing.
For port authorities, OCIANA® analyzes vessel schedules, cargo volumes, and port capacity to enable optimal berth allocation. This helps reduce congestion, shorten vessel wait times, and increase overall throughput, particularly during peak periods when the platform’s predictive algorithms can forecast bottlenecks and dynamically reassign berths.
Ports gain the ability to proactively manage capacity, operate more efficiently, and improve coordination among terminal operators, pilots, and service providers.
For vessel owners and operators, OCIANA® enhances voyage and schedule reliability through AI-driven route and schedule optimisation. By incorporating real-time data on weather, marine traffic density, and port readiness, the platform recommends optimal sailing plans that reduce fuel burn, enhance punctuality, and mitigate environmental impact.
OCIANA’s Schedule Optimisation Planner further supports owners by continuously adjusting schedules in response to emerging risks, such as storms or operational delays, to minimize disruptions and maintain service commitments.
Both ports and vessel owners benefit from OCIANA’s real-time analytics engine, which aggregates data from multiple sources to support proactive decision-making and facilitate seamless, multi-party collaboration.
