Predicting port congestion and vessel skipping in advance is crucial for monitoring dynamics, selecting routes, and developing contingency plans to reduce shipping risks from the source.
Below, Weefreight will provide a detailed analysis, hoping to be helpful to you.
I. Advance Prediction: 3 Core Signals
Port Congestion Index
Monitor port congestion indices and vessel waiting times at ports/anchorages from authoritative platforms (such as the Shanghai Shipping Exchange, Freightos, and port and shipping big data platforms). A continuous increase in the index and waiting times exceeding 3-5 days indicate worsening congestion and a higher probability of vessel skipping.
Shipping Company Announcements and Schedule Changes
Regularly check shipping company websites and freight forwarder notifications. Frequent announcements of vessel skipping, port changes, or schedule delays, or ETA/ETD deviations exceeding 3 days, indicate an unstable route and require vigilance.
Market and Seasonal Signals
During traditional peak seasons (Q3) and 1-2 months before holidays (Christmas, Chinese New Year), popular routes (West Coast of the US, Europe) are prone to congestion; geopolitical conflicts, port strikes, and extreme weather warnings are direct causes of vessel skipping and congestion.
II. Shipping Plan Adjustment: 4 Key Actions
Prioritize Stable Routes and Shipping Companies
Avoid highly congested ports (such as Los Angeles and Long Beach), and choose routes with direct sailings, fewer port calls, and high on-time performance; prioritize leading shipping companies, as they have stronger capacity allocation and risk management capabilities, resulting in a lower probability of vessel skipping. Staggered Shipments and Buffer Periods
Ship 1-2 months in advance during peak seasons to avoid congestion; reserve a 7-10 day buffer period when planning shipping schedules to prevent delayed deliveries due to congestion or port skipping; for non-urgent goods, consider shipping during off-peak seasons for more stable costs and delivery times.
Flexible Port and Transportation Options
- Origin Port: If the main port is congested, switch to a nearby secondary port (e.g., Shanghai to Ningbo, Shenzhen to Guangzhou). While this increases inland transportation costs, it avoids congestion.
- Destination Port: When the US West Coast is congested, consider using the US East Coast route or US West Coast + inland transit; for Europe, choose less congested ports in the Mediterranean or Northern Europe to minimize the impact of port skipping.
- Multimodal Transport: For time-sensitive goods, prepare a contingency plan for switching from sea freight to air freight in advance, allowing for emergency diversion during congestion to avoid contract breaches.
Optimizing Booking and Capacity Strategies
Book in advance to secure capacity and avoid being bumped; agree on “congestion contingency clauses” with your freight forwarder, clearly defining the timeframes and cost responsibilities for port skipping and rerouting; ship in batches to prevent the entire shipment from being delayed due to congestion.
