The head of the Rotterdam port authority is calling on the Dutch cabinet to make a swift decision on expansion of the harbour after container traffic grew by nearly 3 per cent last year. Herman van den Muijsenberg said that the port management rented 100 hectares last year to provide overspill storage and working areas, but it needed 500 hectares for the next four years. 'Industry and government have announced investments in the area amounting to some eight billion guilders (about HK$35.81 billion). Due to these developments, the expansion of the port and its industrial sites is becoming increasingly urgent,' he said. The cabinet is expected to decide in April whether to expand the port. The port authority has announced container throughput rose by 2.9 per cent last year to five million teus (20-ft equivalent units). The port management expects container transshipment to grow by 4 per cent a year to reach 7.5 million containers (11.6 million teus) by 2010.
