Shipping schedule reliability declined at the end of last year, remaining mostly within the range seen in 2024 as global supply chain issues persisted.

In December 2024, global schedule reliability dropped by -0.9 percentage points month-on-month (M/M) to 53.8%, according to a new Sea-Intelligence report.

The Danish maritime data analysis firm said that throughout 2024, schedule reliability has largely remained within the 50%-55% range.

On a year-on-year (Y/Y) level, however, schedule reliability was –3.0 percentage points lower in December 2024. 

Meanwhile, the average delay for late vessel arrivals decreased by -0.23 days M/M to 5.28 days, which is the lowest that the delay figure has been since July 2024.

On a Y/Y level, the December 2024 figure was -0.12 days lower.

Sea-Intelligence said Maersk was the most reliable top-13 carrier in December 2024, with schedule reliability of 60.4%.

 

There were 6 carriers with schedule reliability of 50%-60%, with the remaining 6 carriers within a narrow 47%-50% range. Wan Hai was the least reliable, with 47.9% schedule reliability.

 

 

 

"In December 2024, the difference between the most and least reliable carriers dropped to under 13 percentage points," said Alan Murphy, CEO of Sea-Intelligence.

 

"Only 4 of the top-13 global carriers recorded a M/M improvement in schedule reliability, with ZIM recording the largest increase of 6.0 percent points," he added.
