Port operator DP World's contract to manage the Mina Zayed port for Abu Dhabi Terminals (ADT) will not be renewed after it expires on Dec. 31, the two companies said in a statement.

Following the expiry of the five-year management contract, ADT will resume management of the terminal. DP World said the earnings before interest, tax, dividend and amortisation (EBITDA) contribution from the agreement was "not material" to the company.

ADT, which is a subsidiary of Abu Dhabi Port Company (ADPC), added that discussions surrounding operations for the new Khalifa Port in Abu Dhabi have not resulted in any binding agreement.

The new Khalifa Port is expected to open in the fourth- quarter of 2012.

DP World moved to cut its debt and focus on emerging markets by selling 75 percent of its Australian port operations for $1.5 billion to private equity firm Citi Infrastructure Investors (CII).

DP World -- considered one of the more profitable units of debt-laden Dubai World -- had first-half profit from continuing operations of $206 million, up 10 percent on a recovery in container volumes. (Reuters)
