LONDON (Dow Jones)--BP PLC (BP.LN), said Wednesday that a discharge of liquids was observed from a diverter valve on the drillship Discoverer Enterprise, which is on station at the MC252 wellsite, and said capture of oil and gas through the LMRP cap is therefore temporarily suspended until such time that the cap can be re-installed. MAIN FACTS: -As a precautionary measure, the lower marine riser package or LMRP containment cap system, attached to the Discoverer Enterprise, has been moved off the Deepwater Horizon's failed blow-out preventer or BOP to ensure the safety of operations and allow the unexpected release of liquids to be analyzed. -Capture of oil and gas through the BOP's choke line via a manifold to the Q4000 vessel on the surface continues. Shares closed Wednesday at 333.50 pence. -By Razak Musah Baba, Dow Jones Newswires; +44-20-7842-9275; [email protected] (END) Dow Jones Newswires June 23, 2010 13:19 ET (17:19 GMT)
