In her new role the ship carried coral which had been dredged from Moreton Bay by the converted Landing Ship Tank '' Coral '' ( the former ) to QCL 's cement factory at Darra in Brisbane . Like the rest of QCL 's small fleet , '' Cementco '' underwent a period of extensive maintenance at the Cairncross dry dock in Brisbane once every three years . During the 1974 Brisbane flood the ship 's crew had to fasten '' Cementco '' to the pylons of the Story Bridge to prevent her from being carried down the Brisbane River
