Blank Sailings Erode Ocean Shipping Capacity Gains

Ocean carriers are deploying blank sailings at a rate that undermines recent capacity additions to the global fleet, creating uneven growth patterns that complicate supply chain planning. According to Baker Tilly's global trade management services, this practice is likely to generate longer lead times and reduced schedule reliability for shippers across major trade lanes. The mismatch between fleet capacity growth and actual sailing frequency indicates that carriers continue to manage supply strategically to maintain freight rates, leaving importers and exporters facing unpredictable transit windows.

This dynamic presents a structural challenge for supply chain professionals who cannot rely on nominal capacity figures when planning inventory replenishment or customer deliveries. Blank sailings—whereby carriers skip scheduled port calls or sailings to optimize revenue per slot—have become a persistent feature of the market even as new vessels enter service. The divergence between theoretical and effective capacity requires shippers to build additional buffers into their planning assumptions and reassess carrier performance metrics beyond simple capacity announcements.

For procurement and logistics teams, this environment demands more rigorous demand forecasting, tighter partnerships with carriers to secure space, and contingency plans for extended lead times. The reduced reliability of ocean schedules also increases the appeal of air freight and nearshoring strategies, particularly for time-sensitive or high-value goods, reshaping the competitive landscape for ocean carriers.
