With 67 berths and extensive dry-dock facilities, it is the largest man-made port in the world and the largest port in the Gulf region and in the Middle East.
"Failure to provide facilities for the new container ships would mean the world's most efficient ships could not dock in the UK, driving up the cost of imports and making UK exports less competitive, " said David Gledhill, chief executive of Hutchison Ports UK, which owns the port.
