Studies in core maritime ports related to:

• port access aiming at providing safe maritime access in the form of breakwaters, access channels, fairways, locks and navigational aids;
• basic port infrastructure, with a priority on:
  • development of zero or low-emission multimodal solutions, or;
  • development of ports´ capacities and facilities in relation with offshore wind farms, or;
  • improving connectivity of remote, insular or outermost regions (as defined in Article 349 TFEU) or of Member States with no land border with another Member State;
• shore-side electricity supply;
• port reception facilities for oil and other waste (including residues from exhaust gas cleaning systems) to meet environmental requirements;
• ensuring year-round navigability by means of capital dredging and ice-breaking facilities;
• providing or improving road/rail access and connections within maritime ports.

Support will not be given to studies related to infrastructure dedicated for cruise ships, except as regards shore-side electricity supply. Hinterland connections to the maritime ports are covered by the respective transport mode priorities but may be part of a single Action.
Actions addressing the Core Network may include related elements on the Comprehensive Network, when necessary to optimize the investment. These elements may form up to 10% of the total eligible costs of the Action and shall be presented as a separate work package.

The basic infrastructure for development of zero or low-emission multimodal solutions could include basic infrastructure for improving the interconnection between the maritime transport and inland waterways.
