https://peertube.dngr.us/videos/watch/c8d9c285-26e3-4a79-a59e-87128eac8dcd Lockheed Petroleum Services Ltd. gave viewers a look at the oil and gas wells that operate deep below the water’s surface off the coast of Louisiana in the early 1970s, and the revolutionary technology that made it possible to operate these wells. At mark 02:15, the film introduces the viewer to A.W. Marks, operations superintendent at Lockheed Petroleum Services, who shows the viewer the capsule used to transport workers into the ocean depths. The capsule is lowered into the water at mark 02:40 as the film’s title, “The Subsea Connection,” is introduced. Workers are shown working in the underwater wells, and at mark 04:43 the film tells the viewer how off the west coast of Canada in 1970, Lockheed Petroleum perfected such underwater work in depths of up to 900 feet, and we see footage from those trial runs, including an illustration at mark 06:06 of the hardware sections needed — including wellhead cellar, the service capsule, and the topside support equipment. The narrator continues giving detail of how the subsea connection is made after an oil well is drilled. By mark 07:49, we see a lengthy segment of footage as crews from Lockheed Petroleum and the Shell Oil Company install hardware for a service capsule on a producing subsea well in the Gulf of Mexico in 375 feet of water, followed by scenes of men working in and testing their underwater environment, as a control room on the surface monitors operations and environmental measures. Following a 30-minute ride from beneath the waves, the capsule breaks the waves at mark 17:25, just long enough to take on additional equipment, supplies and a fresh crew before taking another dive. “The idea of men working comfortably beneath the sea to accomplish subsea connections is a reality,” says the narrator at mark 22:22, as the film reaches the end. Background on this: The subsea oil and gas production system developed by Lockheed Petroleum Services Ltd. (LPS) consists of three basic parts—the wellhead cellar, the manifold center, and the service capsule. The system is completely diverless and all components are maintained at one atmosphere of pressure. It is fully automated for remote operation, is capable of through-flow-line (TFL) tool operation, and can be designed for any water depth. The first system was installed in the Gulf of Mexico in Main Pass Block 290 for Shell Oil Company in the summer of 1972. A reentry was made 1 year later for minor repairs and complete inspection. By January 1,1975, the system, operating on a dually completed well, had produced more than V2 million barrels of oil. Four additional wellhead cellars and a production manifold were due for installation in the summer of 1975, The LPS one-atmosphere system has been expanded to provide a means for installing platform riser pipeline tie-ins resulting in a completely welded installation without use of divers or decompression techniques.
