BERLIN, Sept 15 (Reuters) - Germany's cartel office said on Thursday that it did not have any competition concerns regarding planned cooperation by major gas importers and wholesalers Uniper, RWE and EnBW on liquefied natural gas (LNG) terminals.

"In normal times, cooperation between these three very important gas importers and wholesalers and, above all, the exclusive use of import capacities at the terminals would possibly have to be evaluated more critically," said office president Andreas Mundt.

The three firms signed an agreement with the economy ministry in August for the construction and operation of floating LNG terminals in Brunsbuettel and Wilhelmshaven.

The envisaged operator model is initially limited until March 31, 2024, which was welcomed by the office. (Writing by Miranda Murray, editing by Rachel More)
