Overall, other general, bulk and project cargo volume at the Texas port increased nine per cent over the same period to 28.8 million tons year on year.
Container throughput in September at the US Gulf coast port's Barbours Cut and Bayport facilities rose by 22 per cent year on year, reported American Shipper.
"We remain confident of continued growth in the container sector, both on the import and export side, during the remainder of this year and into 2018," the port's executive director, Roger Guenther, was quoted as saying.
The port was significantly impacted by Hurricane Harvey at the end of August, but terminal operations recovered quickly, Mr Guenther said.
"We anticipated that we would receive most of the cargo that was initially diverted following the storm ... and we did," he said.
For example, general cargo facilities handled 400,000 tons of steel, "which is a large volume as we caught up for the week or more of time lost due to the storm," he said.
The port has just taken delivery of three super postpanamax quay cranes, raising the total number of same-size cranes to seven. These new cranes are part of a US$700 million modernisation programme for the Barbours Cut terminal.
Houston's port commission has authorised an agreement with the Texas Department of Transportation for the construction and operation of a rail spur across Texas state highway 146 and Red Bluff Road, to facilitate a phased approach future intermodal service to the Bayport Container Terminal.
An Industry Track Agreement was also approved with Union Pacific Railroad for track and switch modifications at the Bayport terminal. Construction of the spur and crossing and the track agreement support the development of phase one of the Bayport Master Rail Plan, as well as rail service to the 56-acres being developed at Bayport South, the port commission noted.
