Transocean Halts Operations on Discoverer Enterprise

Transocean Inc. reports that drilling riser has separated on the deepwater drillship Discoverer Enterprise, and the rig has temporarily suspended drilling operations for BP on the BP-operated Thunder Horse field at Mississippi Canyon block 822. No injuries occurred and no hydrocarbons were released as a result of the incident. A visual inspection of the wellhead with a remote-operated vehicle showed no wellhead damage. The company currently believes that the rig could resume operations within the next two to three weeks, pending the completion of repairs and the results of an investigation into the cause of the incident.
