1. A computer-implemented method of remotely monitoring the operation of a cargo shipping reefer container configured with a refrigeration system that has installed therewith a control computer coupled with sensors monitoring the operation of the refrigeration system;

  • the method comprises;

    collecting, from the control computer, a first set of observation data and a second set of observation data comprising a respective first and second sequence of measurement values measured by sensors coupled to the control computer;

    collecting preset values, from a database, that define settings for a cargo property value that defines thermo-dynamic properties of the cargo,running a simulation model that receives the first set of observation data and the preset values as input and outputs simulated values;

    wherein the simulation model is configured to output the simulated values as estimates of the second set of the observation data;

    computing an indicator value as a function of residual values computed from the difference between the values of the second set of observation data and the simulated values;

    evaluating the indicator value against a predefined criterion and issuing an alarm signal in case the predefined criterion is exceeded.
