Ensco’s skilled employees, high-quality rig fleet, global presence and operational and safety performance make us the driller of choice in the offshore oil and gas industry. Today we are the leader in customer satisfaction and the world’s second largest provider of offshore contract drilling services.

Standardization of rig design, equipment and operating systems is integral to Ensco’s strategy. Standardization streamlines operations, increases efficiency and reliability, improves inventory management and facilitates employee transfers within our fleet.

Floater Capabilities

Our ultra-deepwater floaters average five years in age and we have one drillship under construction. Our DP3 drillships are built on proprietary Samsung hull designs with advanced capabilities to meet the demands of ultra-deepwater drilling in depths of up to 10,000 feet with a total vertical drilling depth of 40,000 feet. They include many features that increase operating efficiency.

Our ENSCO 8500 Series® ultra-deepwater semisubmersible rigs, capable of drilling in up to 8,500 feet of water, use a proprietary design developed with extensive input from customers to address the drilling requirements of nearly every deep water field around the world. Recently, we added mooring systems to three of these rigs in order to offer customers more options for their drilling requirements. These rigs have built a history of outstanding performance and continue to attract repeat customers.

Our deepwater semisubmersibles are proven performers. Primarily built on Amethyst hulls, these rigs have handled deepwater challenges in fields ranging from Brazil and Angola to the Mediterranean. Additional dynamically positioned and moored semisubmersible rigs capable of working in up to 4,500 feet of water are strategically located and have a strong track record of reliable performance.

Jackup Capabilities

Ensco’s premium jackup fleet is one of the most capable in the world. We continue to execute on our long-established strategy of high-grading our fleet by investing in newer equipment. Since the beginning of 2005, we have invested more than $2 billion in our jackup fleet including the construction of new ENSCO 120 Series ultra-premium harsh environment jackups that are enhanced versions of the KFELS Super A design, ENSCO 140 Series high specification jackups of the LeTourneau Super 116E design, and ENSCO 110, a KFELS B Class premium jackup. All of the ENSCO 120 and ENSCO 140 Series jackups include Ensco’s patented Canti-Leverage AdvantageSM technology, which 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. 

Global Presence

We have drilled some of the most complex wells for super majors, national oil companies and independent operators around the globe and have a presence across six continents. Our rigs are operating today in nearly every strategic oil and gas area in the world, from the North Sea to the “golden triangle” of the Gulf of Mexico, Brazil and West Africa, and from the Middle East and the Mediterranean to Asia and Australia.

We manage our operations through three business units: 

  • North and South America, based in Houston;  
  • Europe and the Mediterranean, based in Aberdeen; and
  • Middle East, Africa, Asia and Pacific Rim, based in Dubai.

Safety Performance

With safety and operational excellence as our highest priorities, we have established a safety performance record that consistently exceeds industry averages. Our skilled employees exceed customer expectations by adhering to our proven safety systems that are actively supported at the highest levels of the organization and applied across the fleet. We also offer extensive training programs to enable our employees to continually build their competence and knowledge. Our Competency Assurance Program is accredited by the International Association of Drilling Contractors.
