    “Ensco History

    Ensco Rose from Humble Beginnings to Become the Leader in Customer Satisfaction and the Second Largest Offshore Drilling Company.


    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.


    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. We redomiciled to the United Kingdom in late 2009 and opened a new global headquarters in London in early 2010.  Ensco was rated #1 in total customer satisfaction in an independent customer survey. 


    Ensco acquired Pride International in May 2011 creating one of the world’s largest offshore drilling companies with operations spanning six continents. The acquisition expanded our fleet to include drillships and gave us a significant presence in Brazil and West Africa. We also continue to high-grade our fleet through new construction and divesting of older rigs. We announced construction of the new ENSCO 120 Series ultra-premium harsh environment jackups that are particularly well suited for work in the North Sea and ENSCO 140 Series high-specification jackups for work in the Middle East. All of the rigs are designed using Ensco’s patented Canti-Leverage AdvantageSM technology that provides cost advantages for customers by allowing them to drill more wells from one location when utilizing the enhanced hoisting capacity at the farthest reach of the cantilever. We also announced construction of several drillships using the newest Samsung GF12000 model. In 2012, Ensco’s growing financial stature was recognized when it was added to the S&P 500 index. Ensco continues to be the world’s #1 rated driller in customer satisfaction, a distinction we have earned four years in a row.”
