Depends on loading capacity of manifolds and valves. Minimum tanks or tank required to be kept open during loading operation.

Time depends on the minimum loading rate agreed by the terminal and experience of person in charge of operation.

The thumb rule would be the minimum pumping rate the terminal can provide. 

As for the time to reduce to topping up rate, that is entirely on the cargo plan and the last tank you have kept for topping up.
