This morning at approximately 0845 CDT a discharge of liquids was observed from a diverter valve on the drillship Discoverer Enterprise, which is on station at the MC252 wellsite. As a precautionary measure, the lower marine riser package (LMRP) containment cap system, attached to the Discoverer Enterprise, has been moved off the Deepwater Horizon’s failed blow-out preventer (BOP) to ensure the safety of operations and allow the unexpected release of liquids to be analysed.
Capture of oil and gas through the LMRP cap is therefore temporarily suspended until such time that the cap can be re-installed. Capture of oil and gas through the BOP’s choke line via a manifold to the Q4000 vessel on the surface continues.
