Ship’s travelling time in approaching the Port of Rotterdam
This study determines the standard or expected travelling time of inbound liner ships in the approach area of the Port of Rotterdam based on AIS ship data. Non-standard or non-expected behaviour is mainly due to ships waiting to be serviced by a pilot, tugboats or the terminal and examples are speed changes, anchoring, drifting and turning circles. Voyages were constructed from the AIS data by collecting information of ships crossing the boundaries of the study area. For each crossing line at the border of the Port of Rotterdam approach area and for each ship size class the standard travelling time was determined.
