100% yes. As long as the container type is in the data we can then calculate the demurrage & detention if its a 20FT, 40FT,40FT HC.  We can calculate Reefers as well.  We can also calculate by carrier i.e Maersk, Hapag Lloyd etc. 

Yes we can, we can also measure combined demurrage & detention, as well as the different tiers. i.e Free time = 5 days then day 6 to 15 at one rate, day 16 to 30+ another rate.  We can also measure off dock storage and also calculate once off charges such as Lo/Lo, Shunt fees etc..
