Stena Line said it was not able to immediately confirm how a partial reopening would affect ferry services, but added a revised timetable would be confirmed on 2 January.
Before the temporary closure, two ferries would often unload and load side by side, something which would not be possible with only one berth reopened.
A spokesperson for Stena Line said: “We are pleased to share a positive update regarding the ongoing closure of the Terminal 3 and Terminal 5 ferry berths at Holyhead Port.
“After diligent assessments and planning, we can now confirm that the timeline for reopening the Terminal 5 ferry berth by 16 January 2025 remains achievable.
“This prediction is subject to reasonable weather conditions, and we will provide further updates as our progress continues.
