How to Handle Port Congestion, Port Skipping & Repeated Container Roll‑Overs at Shanghai Port – Practical Tips for Shippers

How to Handle Port Congestion, Port Skipping & Repeated Container Roll‑Overs at Shanghai Port – Practical Tips for Shippers

Shanghai Port remains congested post‑typhoon Dolphin. Maersk announces new port‑skip calls. Learn actionable steps for shippers to avoid shipment delays and repeated container roll‑overs.

Typhoon Dolphin passed more than one week ago. While terminal operations have resumed at Shanghai Port, severe port congestion has not gone away. As of August 17, vessels face an average waiting time of over 4 days. Backlogged capacity is clearing at a slow pace.

Right when terminals are still struggling to return to normal operation, Maersk has released another port‑skipping advisory, cancelling scheduled Shanghai port calls for selected voyages.

For shippers and freight forwarders with import‑export cargo passing through Shanghai Port, risks of schedule delays, port skipping and repeated container roll‑overs require your close attention. This guide breaks down the current situation and walks you through concrete steps to mitigate supply‑chain disruptions.

Understand The Current Shanghai Port Congestion Background

Typhoon Dolphin forced major container terminals across East China to suspend or restrict operations. Terminals gradually reopened after the storm, yet massive backlogged cargo and delayed vessels cannot be cleared in a short window.

Two layers of cargo flows add pressure to port recovery:

1. Terminals must process cargo and waiting vessels accumulated during the typhoon.

2. Regular inbound cargo volumes keep pouring into the port.

This aligns with analysis from shipping intelligence firm Linerlytica. Its August 11 report noted typhoon‑related disruptions created more than 2.4 million TEU of delayed capacity across North Asia, especially in China. Backlogged vessels are expected to take weeks to clear.

Data from K+N seaexplorer also reflects ongoing stress. Up to August 16, Shanghai Port remained under severe operational disruption, with 7‑day average vessel waiting time hitting 4.42 days. Vessel in‑and‑out efficiency has not returned to normal standards.

What Maersk’s New Port‑Skipping Announcement Means For You

Amid unresolved congestion, Maersk issued a fresh advisory covering Shanghai port call cancellations.

Affected voyages:

‑ SEASPAN GUAYAQUIL 627N/632S

‑ AS CALIFORNIA 628N/633S

These voyages will skip Shanghai port to limit knock‑on delays for subsequent sailing legs. Maersk states cargo originally planned for loading and discharge at Shanghai on these voyages will be rerouted onto alternative sailings. This means your confirmed vessel schedule, port‑of‑call arrangements and downstream logistics plans may all change unexpectedly.

This is not an isolated adjustment. Since late July, Maersk has repeatedly issued weather‑driven Shanghai port‑skip alerts and cancelled multiple scheduled calls. Combined with ongoing Dragon service route adjustments, numerous port‑skip announcements have been released recently.

Key takeaway: supply‑chain impacts from the typhoon persist long after weather conditions improve.

Important: Port‑skip impacts go far beyond Maersk customers

Port‑skipping changes pre‑planned loading and discharge ports, and your cargo may get reassigned to later voyages or alternative transport solutions.

Bear in mind that you can still get affected even if you are not booking directly with Maersk. Most container shipping services operate under vessel‑sharing alliances. Multiple carriers share space on the same vessel.

When one voyage skips Shanghai, customers from other carriers who bought space on that same shared vessel will also suffer consequences. One skipped port call can disrupt shipments booked via many different shipping lines.

Cargo scheduled for loading in Shanghai may get pushed to future sailings. Import cargo planned for Shanghai discharge will face route reshuffling.

When pre‑existing port congestion mixes with port‑skipping, voyage rescheduling and container re‑stowage, your goods may not only get rolled once. In serious cases, containers could be rolled two or more consecutive sailings.

How‑To: Actionable Steps for Shippers To Manage These Risks 

Follow these practical steps if you have import or export cargo moving via Shanghai Port right now.

Step 1: Confirm vessel status with your freight forwarder in advance

Check these critical points with your logistics partner:

‑ Whether your booked vessel will actually make its Shanghai port call

‑ Updated actual vessel departure time against your original schedule

‑ Whether your containers have been reassigned to substitute voyages

‑ Whether you need to prepare backup routing or transshipment plans

Step 2: Build extra buffer time for time‑sensitive shipments

For time‑critical cargo, add sufficient lead‑time buffers. Port congestion, port‑skipping and repeated roll‑overs can derail production timelines and delivery commitments. Extra lead time lowers the risk of missed deadlines.

Step 3: Keep tracking real‑time terminal and carrier updates

Port conditions change rapidly. Carrier advisories and terminal operational notices come out frequently. Stay tuned for latest announcements.

STU Supply Chain closely monitors terminal developments and keeps clients updated with real‑time industry alerts, supporting smooth export arrangements for your goods.

Final Summary

Shanghai Port terminals are open, but typhoon‑driven backlogs will take time to resolve. Port congestion, vessel waiting times and route adjustments overlap, creating high uncertainty for cargo passing Shanghai.

Proactive communication with your logistics provider, early risk assessment and contingency routing planning will help you navigate port‑skip and container roll‑over risks and stabilize your supply chain.
