Dear Yingyi Liu,
The figure uploaded by Jinsong Liu above shows the total mooring reaction load about the platform reference point. If this value is not directly generated by the python wrapper for MAP++ (again I have not used this feature myself, so, I’m not familiar with the details), you could derive it by summing up the fairlead tensions from all lines (Fx, Fy, Fz and the associated moments using the moment arms to the platform reference point).
Best regards,
