It said that volume growth was being boosted through the deployment of more efficient port equipment including gantry cranes and fork lifts.
"Container handling will rise by 40 per cent over the next two years (from the level of 2007)," said Mohammad Faruk, chairman of the Chittagong Port Authority at the recent commissioning of six new fork lifts.
