Ensco Rose From Humble Beginnings to Become One of the Industry's Premier Global Offshore Drilling Companies.
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 period, there were public offerings to raise capital 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.
1996—2007
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, was followed by a $3 billion+ capital commitment to construct seven ENSCO 8500 Series® ultra-deepwater rigs.
2008—Current
To showcase Ensco’s accomplishment of becoming one of the largest offshore oil and gas drilling contractors, we launched a new brand. The new brand emphasizes our strategy of focusing on the ultra-deepwater and premium jackup drilling markets with a dedicated workforce that is commited to safety and operational excellence. In 2009, Ensco redomiciled to the United Kingdom and, in 2010, opened a new headquarters in London.
