Detecting inaccuracies in carrier location data of a vessel

A method for automatically detecting inaccuracies in carrier location data of a vessel, the method comprising:

• receiving the carrier location data generated by a carrier and comprising multiple location data elements, each of the multiple location data elements being indicative of a port at which the vessel has berthed;
• receiving historical vessel location data, generated by the vessel using a location sensor on the vessel and comprising vessel location coordinates;
• matching the historical vessel location data with a predefined list of port locations, to generate validation data comprising multiple validation data elements, each of the multiple validation data elements being indicative of a match between the vessel location coordinates and the port locations;
• determining a numerical correspondence value between each of the carrier location data elements and a corresponding one of the validation data elements;
• and
• based on the numerical correspondence, identifying discrepancies between the carrier location data and the validation data to automatically detect the inaccuracies in the carrier location data.
