Port of Oslo competed with the ports in Antwerpen, Cartagena, Dover, Livorno for the ESPO Award in 2013,  which is awarded each year by the European port organization ESPO. Price premieres projects that contribute to better integration between the city and harbor. This year the theme is cultural heritage. Antwerpen won the prize this year.

Port of Oslo participated with its Maritime Cultural Heritage Plan that identifies maritime heritage it may be worth taking care of. In the Plan we have identified maritime cultural artefacts, buildings, quays, lighthouses and marker buoys, and have assessed them with regard to worthiness for preservation and their current and future use.

- The port is in an ongoing transformation. We made this plan to identify, and be more aware the cultural heritage we administer and gain knowledge for the development of the port areas in the future, says Port Director Anne Sigrid Hamran.

The plan is an important communications tool for people including the city's inhabitants, in explaining the port's historical significance – "The harbour at the head of the Oslo Fjord is the starting point for the city of Oslo".
