From 1954 to 1986 “Mr. Charlie” drilled hundreds of offshore wells off the coast of Morgan City, Louisiana in the Gulf of Mexico. He was the first transportable, submersible drilling rig and an industry springboard to the current offshore rig technology.

“Mr. Charlie” was built in 1952 and finished in 1953. In 1954 he went to work for Shell Oil Company, drilling a new field in East Bay, near the mouth of the Mississippi River. Despite skepticism from offshore industry professionals, “Mr. Charlie” performed up to expectations and went on to drill hundreds of wells for every other major oil company operating in the Gulf, with a cumulative depth of 2.3 million feet.

His barge is approximately 220 feet long and 85 feet wide. Under the living quarters pontoons extend the width to 136 feet. The barge is 14 feet deep, with a 4 foot skirt extending below its bottom on both port and starboard sides. The floor of the platform is 60 feet above the barge, supported by the massive legs that serve to connect the barge and platform. These legs also serve as conduit for connecting services such as: electric, water & air lines, elevator access and other services needed to operate an independent facility, out of sight of land.

“Mr. Charlie” could accommodate a crew of 58. Once “Mr. Charlie” was on location, he was an independent island and nearly totally self-sufficient with room to store drinking water, food, and supplies for the crew. He generated his own electricity, disposed of his own waste, provided his own communication system, and contained enough fuel to accomplish these tasks. He also maintained supplies and equipment to perform his job of drilling a well. He also had to be prepared for any emergency with a complete fire fighting system, blow out preventors, and medical supplies and equipment.

“Mr. Charlie” was capable of drilling wells in water depths up to 40 feet and had a prolific career lasting nearly 4 decades. He revolutionized the offshore oil industry in the Gulf and world-wide. He was retired in late 1986 when drilling activity headed into water deeper than his “feet.” The offshore industry was born in Morgan City, and “Mr. Charlie” carried it into the Gulf of Mexico and shipped it around the globe. “Mr. Charlie” revolutionized the offshore oil industry and lead to the technology currently being used around the world. This historic and renowned structure now continues in a new role, teaching others about an industry that changed the world; the offshore oil industry.

  Semisub rig owner Dolphin Drilling has inked a new contract with Peak Petroleum in Nigeria for its 1974-built Blackford Dolphin.   The firm contract, which follows the letter of award in January, gives the Euronext Growth-listed owner of three rigs the potential to extend the unit’s backlog by a minimum of 120 days and up to 485 days. The deal adds to and will be a direct continuation of the previously announced 12-month contract with General Hydrocarbon Limited (GHL).   Øystein Stray Spetalen-backed company said the effective dayrate associated with the minimum firm period of the contract is $325,000, including the mobilisation fee.   “The final award of the contract for Blackford Dolphin shows the opportunities in Nigeria at a strong dayrate, in addition to building on the backlog for the rig. It also underlines the attractiveness of our assets, and we look forward to returning to revenue-generating operations in 2023,” noted Bjørnar Iversen, CEO of Dolphin Drilling.   Source: Dolphin   Join our mailing list here We are #1 on Google and Bing for the "Largest Mobile Energy Network" Come join our community!
