This Extended presentation will be followed by a Q&A session. The Port of Rotterdam is the leader of the MAGPIE project, which focuses on making the ports of the future more sustainable. As part of this initiative, the introduction of autonomous, unmanned, electric inland vessels aims to make Rotterdam’s hinterland transport chains more environmentally friendly. However, fully automated, unmanned shipping requires high safety standards on the water. In this context, the digital sharing of sailing intentions between vessels presents new opportunities for addressing safety challenges. To navigate and manoeuvre safely in the port, autonomous vessels need sailing intentions in digital form. Autonomous vessels will also digitally inform other ships of their own intentions.
