|Fate||Acquired by Diamond Offshore Drilling|
|Founder||Alden J. "Doc" Laborde|
In 1953, the company was founded by Alden J. "Doc" Laborde, who also founded Tidewater, and John Hayward. Hayward was the builder of the Barnsdall rig and holder of the patent on submersible drilling barge methodology. Charles Murphy, Jr. of Murphy Oil invested $500,000 in the company and assisted Laborde in finding additional investors.
Alexander Shipyard in New Orleans constructed the company's first rig, which was delivered in 1954 and immediately contracted to Shell Oil. The rig was named Mr.Charlie after Charles Murphy. Mr. Charlie was retired in 1986.
After noticing the stability of submersible rigs when they were only partially submerged for relocation, Laborde designed and constructed the first purpose-built V-shaped semi-submersible drilling rig, Ocean Driller, delivered in 1963.
In 1991, Murphy Oil acquired the company.
