Container ships reached their destination ports around the world on time 77 percent of the time in August, a drop of 6 percentage points from July, when global schedule reliability peaked at 83 percent, according to the latest Global Liner Performance Report from SeaIntel Maritime Analysis.
The August decline in on-time port deliveries across more than 10.000 vessel arrivals came after several months of improvements in schedule reliability.
This decline was also seen in the delivery of the individual containers to their ultimate destinations, which SeaIntel tracks in partnership with INTTRA. The global on-time delivery of containers fell to 64 percent from 68 percent in July.
This decline in on-time delivery in August was less severe than for vessel schedule reliability, indicating that some of the gains seen in container delivery had been because of factors other than the timeliness of the vessels, the report said.
The sharp reduction in vessel schedule reliability was due to poor weather conditions, port issues and the phasing-in of super slow-steaming on the main back-haul trades, the report said.
The declines were not confined to individual carriers — all of the top 20 global carriers saw lower vessel reliability in August.
There were significant differences across individual trade lanes.
The backhaul trade from Europe to Asia as well as the trans-Pacific trade saw significant performance reductions.
By contrast, performance actually improved in August in some trades, such as the head-haul trade from Asia to the Mediterranean.
