Schedule reliability

Schedule reliability is a collection of market data that shows the sailing reliability of ocean carriers on the corridor level and is available on the Market benchmarks page.

Xeneta offers an overview of offered market capacity, as well as information on the reliability of individual carriers.

We source our Capacity data from our partners at Sea-Intelligence.

View reliability data

To access the schedule reliability data, go to the Market benchmarks page and select Reliability in the Change dataset menu — the graph with market rates for the selected origin and destination will be updated with the information on average reliability on that corridor:

By default, the reliability data is displayed in percent values, but you can switch it to show average delay (in days) — in other words, the average amount of time the vessels arrived outside of their regular ETA:

If you want to see individual carrier performance, click on the Add comparison button to the right of the graph, and then go to Carrier reliability > Carrier to select individual carriers:

Reliability data for individual carriers is available in percentage values only.

Reliability methodology and calculation

Reliability data is based on a methodology developed by Sea-Intelligence that relies on the vessel arrival time information collected from multiple sources:

• Information from ports
• Data provided directly by carriers
• Information published on carriers' websites
• Track and trace data submitted by shippers
• Terrestrial and satellite AIS data

📘

A vessel is considered on time if it arrives with one calendar day before or after its scheduled ETA.

This data is then used to calculate the reliability scores (in %) shown in Xeneta with the help of a simple formula:

In other words, if a service calls ten ports on its journey and only six of those calls are on time, then the schedule reliability for that specific service will be 60% (6/10*100).

These individual service reliability figures are then combined to calculate the average reliability performance across the corridor that they operate on.
