and time needed to construct a wooden platform to support all or a few of the offshore-type rig. The first MODU The very first genuinely offshore MODU was the Mr. Charlie, created and constructed from scratch by Ocean Drilling and Expedition Co.(ODECO), headed by its inventor and president,"Doc "Alden J. Laborde. The Mr. Charlie (Fig. 2)was a purpose-built submersible barge developed specifically to drift on its lower hull to area and, in a series of flooding the stern down, wound up resting on the bottom to begin drilling operations. Charlie went to its very first area in June 1954, Life magazine blogged about the novel originality to check out for oil and gas offshore. The Mr. Charlie, rated for 40-ft water depth, set the tone for how most MODUs were developed in the Gulf of Mexico (GOM). Generally, an inventor secured financiers, in this case Murphy Oil, and then discovered a consumer with a contract to drill for, in this case Shell Oil, allowing bank loans to be obtained to develop the system. Rigs were installed on surplus The second world war ship hulls customized to drill in a floating position compared with sitting a submersible barge on the ocean bottom, as done in the GOM. Oil business formed partnerships or proceeded individually, but MODUs were not designed and constructed by contract drilling business in California. Before the leasing of oil and gas rights in 1955, oil companies cored with little rigs cantilevered over the side midship of old World War II barges. These barges did not have well-control equipment or the ability to run a casing program. They might just drill to a designated core depth with the understanding that if they drilled into any oil and/or gas sands, they would stop, set a cement plug, and pull out of the core hole. Others followed quickly, with all of them concerned about the marine environment and innovation to allow drilling in rough weather. In 1956, the CUSS 1 was built from another The second world war barge. Try This , developed by the CUSS group(Continental, Union, Shell, and Superior Oil), was 260 ft long and had a 48-ft beam. The initial designers had no examples or experiences to pass, so novelty and innovation were the course of the day: Torque converters on the drawworks were.
