According to the research, schedule reliability has remained relatively steady in recent months, albeit at a far lower level than industry stakeholders would have preferred. Specifically, schedule reliability was down 36.0 percentage points on a year-over-year basis. On a month-to-month basis, the figures fell by 0.2 percentage points to 38.8 percent last month.
The main reason is that container shipping lines continue to grapple with issues such as soaring container demand, empty container shortages and port congestion on the US West Coast.
“None of the top-14 carriers improved their schedule reliability year over year, with all carriers experiencing double-digit decreases of more than -33.0 percentage points,” said Alan Murphy, CEO of Sea-Intelligence.
In May 2021, Maersk Line was the most reliable top-14 carrier, with schedule reliability of 46.2 percent. Next, the three carriers reached on schedule reliability over 40% respectively Hamburg Süd, Hapag-Lloyd and Zim. The remaining includes six carriers ranging from 30% to 40% and four carriers that fall below 30%. In contrast to Maersk Line, Evergreen has the lowest schedule reliability in May 2021 of 25.1%.
According to Sea-Intelligence, Taiwanese shipping business Wan Hai Lines had the biggest reduction by 14.4 percentage points and was the only company to register a double-digit month/month decline.
The Sea-Intelligence report demonstrates schedule reliability and vessel delays for all deep-sea liner services. It contains information on over 12.000 vessel arrivals as well as the scheduled reliability performance of over 60 container carriers in 34 different trade lanes.
