Guaranteed Authentic Yes Additional Details Fascinating piece of financial history from this US-based company that was one of the early pioneers of offshore drilling and, in the late 1950s, developed the technology to drill in greater depths than had previously been thought possible. While other firms worked on shallow-water jackup rigs, Global invented the technique of using ship-mounted drilling rigs to explore previously unreachable parts of the ocean bed for oil and natural gas. It soon became the king of the deep-water drillers and, by the mid-1960s, Global Marine Inc. was one of the world’s biggest offshore drilling firms, with rigs off the coasts of Alaska, Nigeria, Australia, Libya, California, and Louisiana, and in the Persian Gulf and the North Sea. It was not an oil or gas company and did not sell either commodity, but it rented its rigs and crews to oil and gas companies for offshore drilling.
