Corporate history[edit]

Rowan Companies[edit]

Rowan Drilling Company, Inc. was founded in 1923 by brothers Charles and Arch Rowan as a contract drilling business.[5]

In 1947, the drilling company was reorganized as Rowan Companies, Inc.[6]

In 1964, the company began paying a cash dividend to shareholders, which it continued without interruption for the next couple of decades. The company was publicly traded on the New York Stock Exchange under the ticker symbol RDC.[7]

In 1994, Rowan acquired the assets of Marathon LeTourneau Company.

In 2004, Rowan sold its aviation subsidiary business Era Aviation, Inc. for US$118.1 million in cash. The subsidiary chartered helicopter and fixed-wing services.

In 2009, W. Matt Ralls became Rowan's President and Chief Executive Officer.

In 2010, Rowan completed the acquisition of Skeie Drilling & Production ASA, including its three North Sea compliant (N-class) jack-up rigs under construction. Rowan adds three EXL class (enhanced LeTourneau Super 116E) rigs to its fleet and the first N-class rig comes into service.

In 2011, Rowan announced plans to enter the ultra-deepwater market with three high-specification drillships, expected to be delivered starting in late 2013. Rowan also completed the sales of its manufacturing subsidiary, LeTourneau Technologies, Inc., and its land drilling operations.

In January 2014, Rowan delivered its first ultra-deepwater drillship, the Rowan Renaissance. Additional drillships are expected to be delivered in June and October 2014 and March 2015.

In 2013, Thomas P. Burke became President of Rowan, while remaining Chief Operating Officer. W. Matt Ralls remained Chief Executive Officer.

LeTourneau Technologies[edit]

R. G. LeTourneau founded his company R.G. LeTourneau, Inc. in 1929 in California as a contractor of earthmoving equipment. LeTourneau manufactured products in Longview, Texas.[8] During World War II, the company provided 70% of the Allies' earthmoving equipment. In 1954, it built the first jack-up drilling platform. In 1955, it made the first log-stacker machine. In 1965, the company made the first intermodal crane.[9]

Marathon LeTourneau Company designed all of Rowan Companies' jack-up rigs, and delivered the last one to Rowan as an independent company in 1986.[6]

In 1994, Rowan Companies acquired the assets of Marathon LeTourneau Company.[6]

In 2004, LeTourneau formed an alliance with SourceOne Drilling Systems.[9]

In 2006, LeTourneau changed its name to LeTourneau Technologies, Inc.[9]

In 2011, Rowan announced the sale of LeTourneau Technologies to Joy Global.[10] The sale of LeTourneau Technologies to Joy Global was completed in late 2011. Joy Global subsequently sold LeTourneau's Drilling, Marine, and Power divisions to Cameron International in October 2011.[11]

LeTourneau Ellis Williams[edit]

Ellis Williams, Jr. founded the Ellis Williams Company, of Houston, Texas. Michael R. Williams served as President. EWCO, Inc. was a sibling company which operated as Traitex Machine Co. and made drilling mud pumps.[8][9]

On January 31, 2000, Rowan's subsidiary LeTourneau acquired Ellis Williams Company, and also its sibling company EWCO, Inc., for US$9 million.[9] After the acquisition, Ellis Williams, Jr. remained with the new subsidiary as a design consultant, and Michael R. Williams remained as Senior Vice President and General Manager.[8] The new subsidiary company was renamed LeTourneau Ellis Williams, Inc.


Oilfield-Electric-Marine, Inc. had been in business in Houston, Texas since the late 1970s. It made both AC and DC motors and drive systems, electric consoles for marine drilling industries, and medium voltage switchgear.[12]

On February 1, 2002, the Rowan Electric, Inc. subsidiary unit of Rowan Companies acquired assets of Oilfield-Electric-Marine, Inc., which operated as OEM Power Systems, and the Rowan subsidiary company also acquired Industrial Logic Systems, Inc. the same day. The deal was completed for US$8 million in Rowan common stock.[6][12][9]
