ONE revises Irish Sea Express rotation to add direct Southampton Ireland link

Estimated reading time: 2 minutes

Ocean Network Express will revise its Irish Sea Express service later this month, replacing Rotterdam with Southampton on the Dublin and Cork loop as carriers continue adjusting intra Europe networks to improve schedule reliability and regional coverage.

The updated Irish Sea Express, known as IRX, will operate on two separate loops. One rotation will connect Southampton, Dublin, Cork, and back to Southampton. A second loop will continue between Rotterdam and Belfast.

The carrier said the changes are designed to strengthen network efficiency while adding a direct connection between Southampton and Ireland. The revised rotation is scheduled to take effect in late May 2026.

For shippers moving cargo between southern England and Ireland, the change removes Rotterdam from the Dublin and Cork rotation and creates a shorter regional link. In practical terms, it resembles replacing a transfer flight with a nonstop route. Fewer port calls can often mean fewer delays and improved cargo predictability.

The Rotterdam and Belfast connection will remain in place under a dedicated loop, allowing ONE to maintain coverage in Northern Europe while separating Irish Sea operations.

Container carriers across Europe have continued to adjust regional feeder and short sea services over the past year as congestion, weather disruption, and changing cargo flows pressure schedule reliability. Smaller network refinements like the IRX adjustment can have a noticeable impact on transit consistency for exporters and importers handling time sensitive cargo.

ONE said the updated structure reflects its commitment to maintaining comprehensive European coverage while improving service quality for customers operating in the intra Europe market.

The carrier described the revised service as part of its broader effort to strengthen operational reliability and network performance across regional trades.
