Techniques for 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 include: collecting a first and second set of observation data comprising a respective first and second sequence of measurement values measured by sensors coupled to the control computer; running a simulation model that receives the first set of observation data as input and outputs simulated values; the simulation model is configured to output the simulated values as estimates of the second set of the observations; computing an indicator value as a function of residual values computed from the difference between the values of the second set of observations and the simulated values; and evaluating the indicator value against a predefined criterion and issuing an alarm signal in case the predefined criterion is exceeded.
