If you are asking how many days it will take the rig to get to the landing at Morabisi from Georgetown, it is only 1 or 2 days as far as I know. They use jetty going upstream very fast.
They go to Parika by road, get a ferry from Parika to Bartica. Then another jetty from Bartica to Morabisi.
It is 40km from Georgetown to Parika on sealed road.
55km from Parika to Bartica on Ferry.
125km from Bartica to Morabisi Turesi site by river
