2012 began with a narrowly averted tragedy when a large as-yet unidentified dredger suddenly sank in the Port of Ngqura,  South Africa's newest deep water port. According to reports a rescue call went out at 02:00 on 1 January from the vessel brought in from China to work on the expansion of the port by constructing a second harbour quay. Fifteen workers were rescued from the vessel by emergency personnel and booms were floated to prevent oil spills.  The Herald reports that one of the four posts used to stabilise the dredger while it was working  gave way. However, Transnet says it is still investigating the circumstances leading up to the sudden sinking of the dredger. Regular port operations are reportedly not affected by the incident.
