Nameplate volume is 14ships X 60000tonnes X 12 months = 10mtpa. So one ship every 2 days on average for 14 ships/ month to achieve nameplate volumes.
Having said that, GBG will announce nameplate once they can demonstrate nameplate volume and quality (68% Fe). They don't need to be operating at nameplate for a period of time to announce it. Once they achieve it, an announcement will go out. sdo
