Ensco Rose from Humble Beginnings to Become the Leader in Customer Satisfaction and the Second Largest Offshore Drilling Company.
1987—1996
We commenced trading as Energy Services Company, Inc. (formerly Blocker Energy Corporation) and continued growing through the acquisition of Penrod Drilling (1993) and Dual Drilling (1996). During this time, we raised capital through public offerings to purchase and refurbish equipment. We also branched out from the contract drilling business into various associated businesses including a tool and supply company, engineering services and the marine transportation business. In 1995, we changed our name to ENSCO International Incorporated and listed our shares on the New York Stock Exchange under symbol ESV.
1997—2008
With a renewed strategy to focus solely on offshore drilling with a premium fleet, we divested marine vessels, platform rigs and the majority of barge rigs. Through new construction and acquisitions, we grew our jackup rig fleet and entered the developing ultra-deepwater market. The construction of ENSCO 7500, our first ultra-deepwater semisubmersible delivered in 2000, was followed by a multi-billion dollar capital commitment to eventually construct seven ENSCO 8500 Series® ultra-deepwater rigs. We launched a new brand to emphasize our strategy of focusing on the ultra-deepwater and premium jackup drilling markets with a dedicated workforce that is committed to safety and operational excellence.
2009—Current
In 2009, Ensco's deepwater strategy became reality with the first two ENSCO 8500 Series® ultra-deepwater rigs successfully commencing operations in the U.S. Gulf of Mexico. In 2010, two more ENSCO 8500 Series® rigs were delivered. We redomiciled to the United Kingdom in late 2009 and opened a new global headquarters in London in early 2010. During 2010, Ensco high graded its fleet by acquiring ENSCO 109, a Mod V Super B high-spec jackup built in 2008 and divesting four jackups. In May 2011, Ensco acquired Pride International to create the second largest offshore driller in the world with operations spanning six continents.
