In Q4 2023, unitised traffic at ports on the island of Ireland displayed resilience amid challenging economic conditions. RoRo traffic in the Republic of Ireland (ROI) declined by 2% to 289,971 units, marking the first sub-290,000 performance in five years, primarily due to the cessation of the P&O Dublin-Liverpool service. Meanwhile, Northern Ireland's RoRo volumes grew by 4% to 222,740 units, with overall island-wide RoRo traffic rising 1% year-on-year to 512,711 units. Dublin Port saw a 5% decline, while Rosslare Europort grew 12%, driven by a shift toward direct ROI-EU routes post-Brexit. LoLo traffic at ROI ports rebounded with a 5% increase to 278,850 TEUs, reversing a year of steep declines. Despite stagnation in overall unitised traffic amid inflation, rising interest rates, and global economic pressures, the sector retained much of the gains from the COVID-19 trade surge, highlighting its underlying resilience.
