New Geofence System Aims to Improve Ship Movement, Reduce CO2 Emissions
The Port of Rotterdam has implemented a new geofence system for optimizing ship movements. The system is the first step for the deployment of the Just-In-Time sailing project, whose goal is to reduce the hang time of vessels in the port and, hence, reduce emissions.
The geofence is an imaginary boundary surrounding the Port of Rotterdam, which is demarcated as an unofficial boundary in the implementation of the system.
The geofence boundary for the Port of Rotterdam has been defined to be 240 nautical miles from the Maascenter buoy. When any vessel passes that boundary, it is assigned a time of arrival and is considered to have entered the "inland shipping port-passage planning area." The port authorities and shipping agents then plan for the precise scheduling of the vessel's arrival at the port to minimize its stay.
This approach of just-in-time arrivals is reported to have a reduction in the vessel's fuel consumption and a reduction in CO2 emissions by 4.23%.
