Diamond Offshore Drilling, Inc. is an offshore drilling contractor. The company is headquartered in Houston, Texas, United States, and has major offices in Australia, Brazil, Mexico, Scotland, Singapore, and Norway.
In 2017, the company's revenues were primarily from Anadarko Petroleum (24.9%), Petrobras (18.9%), Hess Corporation (16.0%), and BP (15.8%). Operations outside of the United States accounted for 58% of the company's revenues in 2016.
In the early 1960s, Brewster-Bartle, an onshore drilling company, filed bankruptcy. In 1964, Don McMahon acquired Brewster-Bartle from its bank creditors and formed Diamond M Drilling Company, named after Diamond M Acres, his ranch near Simonton, Texas, which then expanded into offshore drilling.
In 1970, Diamond M became a public company.
In 1977, Kaneb Services acquired the company for $102 million.
In 1992, Diamond M Corporation acquired ODECO from Murphy Oil for $358 million. Shortly thereafter, Diamond M Corp. briefly changed its name to Diamond M-ODECO Drilling Inc. before becoming Diamond Offshore Drilling, Inc. in 1993.
Worker asbestos exposure
In 1989, Diamond's predecessor bought 6 drilling rigs from the predecessor of Kaneb Management. Some of Kaneb's employees continued to work for Diamond after the transaction and then sued Diamond for personal injuries they allegedly suffered from asbestos exposure while they worked for Kaneb. In a 2013 filing with the SEC, Diamond acknowledged that its equipment had been used for the "manufacture and use of asbestos-containing drilling mud" but sought to be indemnified from liability.
