"Owing to continued congestion at our Birkenhead Port, only confirmed bookings will be permitted on to the quay. Please do not present at the port unless you have a confirmed booking. Birkenhead Port will continue to work to a 12hr rule for drop off. In Addition, we ask that all bookings are updated at the earliest opportunity with correct information, including Customs numbers where applicable, or cancelled if not required. This also applies to DGNs (Dangerous Goods Notes) which must be submitted and processed at least 2hrs prior to arrival at the port." Stena Line
