The ore quay at Saldanha has two berths where two vessels of 310,000 deadweight tonnage can simultaneously tie up at the iron ore jetty. The terminal operates 24/7 and has the capacity to offload 10,000 tonnes per hour onto a vessel. From arrival to departure an ore vessel carrying 170,000 tonnes will be in Saldanha Bay for just 24 hours.
