A New Era for Shippers, with Blanked Sailings Now a Fact of Life

1. Article summary

Container shipping is entering a new phase where blanked sailings are no longer an occasional response to changing demand but a regular part of carrier capacity management. According to new analysis by Sea-Intelligence, shipping lines are now routinely withdrawing between 10% and 14% of scheduled vessel capacity across the world's major east–west trade lanes to better balance supply and demand.

While the extreme disruption experienced during the pandemic has eased, carriers are increasingly using planned sailing cancellations to manage vessel utilisation and maintain freight rates. The analysis also found that although shipping capacity has grown significantly since 2019, the amount of capacity being removed through blanked sailings has increased even faster. The result is a more predictable, but permanently tighter, shipping environment that requires businesses to adapt their planning strategies.

2. What shippers should consider

• Expect blanked sailings to remain a regular feature of international shipping rather than a temporary market condition.
• Book shipments earlier to improve the likelihood of securing space during peak demand periods.
• Build additional flexibility into inventory planning and lead times to reduce the impact of cancelled sailings.
• Consider alternative routings or ports where capacity constraints become more pronounced, particularly on heavily utilised trade lanes.
• Work closely with your freight forwarder to monitor schedule changes and identify alternative options before disruptions affect delivery timelines.

3. Moving forward

As carriers continue to manage capacity through planned sailing cancellations, supply chain resilience will increasingly depend on proactive planning rather than reacting to disruptions. Businesses that maintain greater flexibility in their inventory, booking schedules and transport strategies will be better positioned to minimise delays and maintain service levels as blanked sailings become part of the industry's long-term operating model.
