Mr. Charlie drilling rig attains National Historic Landmark status

April 18, 2025
Completed in 1953, the submersible rig was the world's first Mobile Offshore Drilling Unit.

The Mr. Charlie offshore drilling rig has been named as National Historic Landmark, in recognition of the property’s national significance in the history of the United States.

Located in Morgan City, Louisiana, the rig – often referred to simply as “The Rig Museum” – has served as both a museum and training facility since the mid-1980s. The designation was made last December by then-Secretary of the Interior Deb Haaland.

The Historic Sites Act of 1935 authorizes the Secretary of the Interior to identify and recognize nationally significant places that best represent the American experience. Landmark designation recognizes and encourages the preservation of places that have exceptional value for commemorating or illustrating the history of the United States.

Designed by Alden “Doc” Laborde, Mr. Charlie is the first offshore drilling rig that was fully transportable, submersible and self-sufficient, allowing it to drill more than 200 oil and gas wells along the Gulf Coast between 1954 and 1986.

Laborde, a young US Navy engineer, had the idea that a self-sufficient oil rig could be placed on a barge and floated in 40-foot water depths. The idea was revolutionary, but all of the major companies involved in the oil and gas industry at the time passed on the idea. He made the decision to search for investors and eventually found a partner in Charles Murphy, the owner of an independent oil company from El Dorado, Arkansas. Thus the rig was named "Mr. Charlie." 

Construction on Mr. Charlie began in 1952 at Alexander Shipyards in New Orleans and was completed in late 1953. Mr. Charlie would go on to drill hundreds of wells—a cumulative 2.3 million feet up and down the Gulf Coast for Shell Oil, as well as many other oil companies.

Thus Mr. Charlie became the first and the longest operating Mobile Offshore Drilling Unit (MODU) in the world.

By the mid-1980s, offshore drilling activity had moved beyond 40-foot depths, rendering Mr. Charlie ineffective for larger projects. An effort to preserve Mr. Charlie was led by Morgan City oilmen and former workers on the Mr. Charlie rig. It has now served as an educational museum and training facility for decades.
