Dubai's DP World, one of the world's largest port operators, said Thursday its half-yearly profit has surged 21.9 percent to $405 million, aided by the acquisition of a logistics provider.

Revenues grew 14.5 percent to $1.9 billion, it said.

DP World's ports handled 14.378 million TEUs (twenty-foot equivalent units), the standard used for sizing containers in the shipping industry, 3.5 percent up from last year.

DP World Chairman Sultan Ahmed bin Sulayem said the "strong set of results" were "aided by the acquisition of EZW", the logistics provider.

Economic Zones World is an operator of economic zones, technology, logistics and industrial parks. Its portfolio includes Dubai's Jafza, one of the world's largest free zones.

DP World runs more than 65 marine terminals across six continents, including Dubai's Jebel Ali port, the largest in the Middle East.
