This research project aims to map out the EU inland waterway ports, by assessing the development stage of Onshore Power Supply (OPS) facilities for river cruise ships while at berth. It involves categorising these ports based on their planning, funding, or implementation stages of OPS infrastructures, and comparing them against key EU legislation requirements, particularly the Alternative Fuel Infrastructure Regulation (AFIR) and the Trans-European Transport Network (TEN-T) policies.
