When the Zhen Hua No.23 entered Durban harbour in South Africa on Saturday, 11 April 2009 around 0700, it attracted considerable attention due to its immense size of 804 ft long and its beam of 131 ft. Equally interesting were the six pre-assembled harbour cranes weighing a total of 2,540 tonnes onboard the vessel. The vessel is purpose-built to transport abnormal project cargo. Its cargo included two rail mounted gantry (RMG) cranes weighing 285 tonnes each and purchased by Transnet Port Terminals for R36 million apiece. The cranes will be used to improve port-rail efficiency within the busy Pier 1 container terminal. The vessel also carried four ship-to-shore cranes weighing 985 tonnes each, destined for the Port of Rotterdam in the Netherlands.
