ENSCO International Finalizes New Ultra-Deepwater
Semisubmersible Rig Construction Contract	
 	
      Dallas, Texas, May 6, 2008 ... ENSCO International Incorporated (NYSE: ESV) reported that one of its subsidiaries has finalized the construction contract for an ultra-deepwater semisubmersible rig to be named ENSCO 8504. The contract for construction of the rig was entered into with Keppel FELS Limited (Keppel FELS) Shipyard in Singapore at a total project cost currently projected to be $512 million. Delivery is expected in the second half of 2011.	
 	
      ENSCO 8504 is the Company's fifth ultra-deepwater semisubmersible rig in the ENSCO 8500 Series® currently under construction, and will be part of the Company's six-rig deepwater fleet that includes the ENSCO 7500 deepwater semisubmersible that has been in service since 2000. Four of the ENSCO 8500 Series® rigs are now contracted to customers for term work commencing upon delivery and marketing of ENSCO 8504 already is underway.	
 	
      The ENSCO 8500 Series® deepwater semisubmersibles are enhanced versions of ENSCO 7500, and are based upon an ENSCO proprietary design. Enhancements include a two million pound quad derrick, offline pipe handling capability, increased drilling capacity, improved automatic station keeping ability and larger living quarters. The 8500 Series rigs will be capable of drilling in up to 8,500 feet of water. With these capabilities and features, the rigs will be especially well-suited for deepwater development drilling.	
 	
      Daniel W. Rabun, ENSCO's Chairman, President and Chief Executive Officer, commented: "We are pleased to again partner with Keppel FELS as we execute on our strategy to play a significant role in meeting the unprecedented demand for deepwater drilling equipment. Our $2.0 billion investment in the ENSCO 8500 Series® rigs demonstrates our commitment to expanding our deepwater rig fleet. We estimate that over one-quarter of our revenues will be derived from our deepwater fleet after all rigs commence operations."
