Roll-on-Roll-off (RoRo) ferry traffic increased by 18% in the first three months of the year compared to the same period in 2021, new figures from the Irish Maritime Development Office (IMDO) show.

The jump in movements followed the ending of pre-Brexit stockpiles and Covid-19 restrictions which had led to reduced volumes in the first quarter of 2021.

Much of the growth came on routes between the Republic of Ireland and Great Britain, which increased by 22%.

Traffic that passed through Dublin Port to and from Great Britain was up 24% compared with the same period last year.

While in Rosslare, volumes of RoRo traffic to and from Great Britain was up 4%.

Ferry traffic between Ireland and the EU continued to hold on to huge increases seen in 2021, and grew by 10% over the first quarter.

The Port of Cork is also performing strongly, the IMDO said.

Two new services were added through the port last year with those volumes now adding to performance.

There was no change in the volume of RoRo traffic in Northern Ireland between January and March of this year, compared to the same period in 2021.
