Don't know but I think one at a time only from where the left hand one is positioned in photos above - see pics in recent announcements too: always seems to be same place.
Based on images of pairs of 4000t barge coming and going, loading them via dump truck and excavator ~ 2-3 days per barge to load - length of journey still the bottleneck. Possible other consideration is unloading the 800k barges that deliver new coal from Krajan is also in same location so at least at the moment there is ample time for this restocking. Need conveyor to be operational - hopefully brought forward with funds from this quarter.
