28 Ships Queue at Mombasa as Dar es Salaam Diversion Strains Region
A significant backlog has developed at the Port of Mombasa in Kenya, with 28 ships currently queuing for berth access. This congestion stems from diversions away from the Port of Dar es Salaam in Tanzania, suggesting operational challenges or capacity constraints at the Tanzanian facility are pushing vessel traffic to alternative regional hubs. This redistribution of maritime traffic is creating bottlenecks in East Africa's primary container gateway, affecting transit times and increasing port charges for importers and exporters across the region. The queuing situation reflects structural vulnerabilities in East African port infrastructure. When primary ports face disruptions—whether from maintenance, labor issues, or capacity limits—neighboring ports lack sufficient redundancy to absorb overflow traffic efficiently. Shippers relying on East African corridors now face extended dwell times, demurrage costs, and unpredictable vessel schedules. For supply chain professionals, this situation underscores the importance of diversification strategies and real-time port performance monitoring. Organizations dependent on Mombasa or Dar es Salaam routing should reassess buffer inventory policies, consider alternative East African entry points, and establish contingency relationships with freight forwarders and port agents who can navigate the dynamic operational environment.
East Africa's Port Bottleneck: What the Mombasa Queue Reveals About Regional Logistics
The sight of 28 vessels queuing for berth access at the Port of Mombasa signals a critical stress point in East Africa's supply chain infrastructure. Behind this congestion lies a cascading failure of regional port resilience: when the Port of Dar es Salaam experiences operational constraints, the entire maritime corridor strains under concentrated traffic at alternative hubs. For supply chain professionals managing trade flows into East Africa, this situation demands immediate strategic reassessment.
The diversion from Dar es Salaam to Mombasa reflects a structural vulnerability in the region's port network. East Africa relies heavily on two major containerized gateways—Mombasa (Kenya) and Dar es Salaam (Tanzania)—to serve a vast inland hinterland including Uganda, Rwanda, Burundi, Ethiopia, and South Sudan. When one gateway falters, the other absorbs overflow with limited ability to scale operations. Unlike mature port systems in Southeast Asia or Europe, East African ports lack the operational flexibility—additional berths, redundant cargo handling equipment, or surge staffing protocols—to gracefully absorb 20-30% traffic spikes. The result is predictable: extended vessel waiting times, stranded inventory, and ballooning logistics costs.
A backlog of 28 ships translates into real operational pain. Each day a vessel sits in a queue costs shippers demurrage fees, delays downstream cargo discharge, and ties up container inventory. For just-in-time supply chains—especially those serving retail, automotive, and fast-moving consumer goods sectors—even a 5-7 day delay can trigger bullwhip effects upstream. Importers must absorb the demurrage charges (often $1,500–$3,000 per day per vessel), which get passed through to end consumers or absorbed by already-thin margins. Stevedoring labor becomes a secondary constraint: even if additional berths open, insufficient dock workers create a second chokepoint, prolonging cargo discharge and extending the queue.
Operational Implications and Strategic Responses
Shippers and logistics managers should take immediate steps to navigate this disruption. First, establish direct communication with freight forwarders and port agents in Mombasa to monitor queue status and predict vessel berthing windows. Real-time visibility tools are invaluable here. Second, assess whether time-sensitive cargo justifies a modal shift: airfreight is expensive but preferable to weeks of inventory aging in port. Third, evaluate alternative entry points—some cargo may route through Beira (Mozambique) or even South Africa's ports, depending on origin, destination, and cost tolerance.
Longer term, this event highlights the fragility of single-port dependency. Organizations with substantial East African footprints should diversify supplier networks geographically, negotiate agreements with multiple freight forwarders to secure space during congestion events, and build inventory buffers specifically for supply chain disruptions at the region's ports. Supply chain resilience in East Africa requires acknowledging that port disruptions are not anomalies but structural features of an infrastructure system that has not kept pace with trade volume growth.
The Bigger Picture: Capacity and Investment Gaps
The Mombasa queue also signals a broader investment deficit in East African port infrastructure. While global container traffic has grown steadily, port expansion in the region has lagged. Mombasa and Dar es Salaam are constrained by physical berth limitations, aging cranes, and administrative delays. Proposed expansions—including newer terminals and deepwater facilities—remain in planning or early construction phases. Until these projects come online, supply chain professionals should expect periodic congestion to be endemic rather than exceptional.
For multinational companies and regional traders, this means factoring port risk into financial planning. The cost of congestion-driven demurrage, inventory carrying costs, and potential service level failures should inform procurement and supplier selection decisions. Conversely, this also presents an opportunity: companies that master supply chain flexibility and resilience in this environment gain competitive advantage over rivals still relying on brittle, single-path logistics networks.
The 28 vessels queuing at Mombasa are a symptom, not the disease. The disease is structural undersupply of East African port capacity relative to regional trade demand. Until that gap closes through major infrastructure investment, supply chain disruptions will remain a recurring cost of doing business in East Africa.

What This Means for Your Supply Chain
What if Mombasa port berthing delays extend to 10+ days?
Model the impact of extended vessel waiting times (10-14 days) at Mombasa port on inventory levels, landed costs, and service level targets for shipments destined to Kenya, Uganda, and the East African inland region. Assume 28-ship baseline queue with progressive slowdown in cargo discharge rates.
Run this scenarioWhat if Dar es Salaam capacity remains offline for 4 weeks?
Simulate sustained traffic diversion from Dar es Salaam to Mombasa and alternate East African ports over a 4-week period. Model cascading effects on port throughput, berth utilization, vessel scheduling, and total logistics costs for shippers with split routing between the two ports.
Run this scenarioWhat if port demurrage charges increase 30% due to congestion surcharges?
Calculate the cost impact of elevated demurrage fees and congestion surcharges across a typical monthly import volume mix arriving via Mombasa. Model total cost per TEU, inventory carrying costs, and cash flow implications for importers of containerized goods into East Africa.
