FRANKFURT (Dow Jones)--BP PLC's (BP) Chief Economist Christof Ruehl calls for common global security standards for deep water drilling in an advanced copy of an interview on Germany's WDR radio station released in part on the radio station's website. Ruehl says Gulf of Mexico disaster could be repeated at any time and questions why the risks involved in deep water drilling should be increased through a lack of unified national systems. The interview will play July 24 on the radio station's Profit program. Radio station website: http://www.wdr.de -Frankfurt Bureau, Dow Jones Newswires; 49-69-29725-500.
