A blank sailing, or void sailing, is a scheduled vessel call or an entire voyage that the carrier cancels. The service skips a port or a whole rotation for that week, and cargo booked on it is rolled to other sailings. Carriers blank sailings mainly to manage capacity and recover schedules.
Two motives dominate. Commercially, blanking removes capacity when demand dips, supporting utilisation and rates, which is why waves of blank sailings follow soft markets and holiday lulls like Lunar New Year. Operationally, skipping a call lets a badly delayed vessel catch up to its schedule.
The impact lands on shippers as rollovers, longer effective transit, and bunched arrivals when the next vessel carries two sailings’ worth of cargo, which in turn stresses terminals and can feed congestion.
A blank sailing announces itself in tracking as a schedule discontinuity: the expected voyage disappears, your booking’s vessel changes, or ETD jumps by roughly a week. Watching your lane in TrackingMCP surfaces the change per container the day it happens, and port pages show the arrival-side bunching when the catch-up vessel lands.

Capacity discipline protects the whole network’s economics: sailing a half-empty ship costs nearly as much as a full one. Removing the sailing preserves utilisation on the remaining ones.
Typically about one service cycle, often a week on weekly loops, plus any knock-on from missed connections. Cargo needing tight transshipment windows can lose more.
