DP World has boosted traffic by 10 percent in 2011 from a year ago on strong growth in emerging markets, prompting a forecast that core earnings would meet expectations. The increase, to 54.7 million 20-foot equivalent units across more than 60 terminals, was driven by 12 percent growth at DP’s flagship United Arab Emirates terminal to 13 million TEUs. Fourth quarter traffic climbed 8.5 percent year-over-year to 14.1 million TEUs. DP World also booked strong results from the Asia-Pacific, Africa and Americas regions together with the addition of new capacity from terminals in Karachi, Pakistan, and Vallarpadam, India, both of which opened in early 2011.
