GLOBAL liner schedule reliability has plunged to its lowest level since 2011 to 30.9 per cent in the first month of the year.

Sea-Intelligence's latest Global Liner Performance (GLP) report showed that schedule reliability dropped by 0.9 percentage points month on month to 30.9 per cent - the lowest ever global schedule reliability since Sea-Intelligence started the measure in 2011.

On a year-on-year level, schedule reliability was down 3.8 percentage points. Despite the low schedule reliability since January 2021, there hasn't been much fluctuation, with the global scores largely between 30 to 40 per cent.

"The average delay for late vessel arrivals decreased slightly to 7.38 days, the sixth consecutive month with the delay figure above 7 days," said Alan Murphy, CEO, Sea-Intelligence.

The comprehensive report covers schedule reliability across 34 different trade lanes and more than sixty carriers.

In January, 14 carrier had schedule reliability of 46.9 per cent, followed by Hamburg Sud with 42.8 per cent. MSC and HMM had schedule reliability between 30 and 40 per cent, with six carriers recording schedule reliability of 20 per cent to 30 per cent.

The remaining four carriers had schedule reliability of under 20 per cent, with Evergreen recording the lowest January 2022 schedule reliability figure of 15.0 per cent.

Ten carriers recorded a month on month improvement in schedule reliability, while five carriers recorded a year-on-year improvement in schedule reliability, with only three carriers recording double-digit year-on-year declines.
