In 1961, the drilling barge CUSS I made scientific historical past when it was used to drill into the ocean flooring to get core samples of the earth’s never-before-penetrated second layer, generally known as the Mohorovicic Discontinuity or “Moho”.
All began in 1948 when Shell Oil Company joined Continental Oil, Union Oil and Superior Oil in a three way partnership – the CUSS Group.
In 1953, the Union Oil engineer Robert F. Bauer joined the CUSS as supervisor of offshore operations. Bauer had been a cowboy in Utah in his youth, then rode to California on a truck with hen. His uncle gave him a job as roustabout on a rig. In 1942 he earned a level in petroleum engineering from the University of Southern California then acquired a Master’s diploma from Stanford University.and rapidly discovered an employment with Union Oil. Bauer turned a key participant in growing the CUSS Group offshore drilling vessels.
In 1953 the partnership of the 4 corporations determined to transform a 260 ft World War II ex-Navy patrol craft right into a drilling vessel named the Submarex, and conduct the primary recognized dynamic positioning experiments. By 1954, the artwork of this kind of drilling, which included the options of gap re-entry – return circulation – and blowout prevention, was lowered to a sensible exploratory technique.
Experience thus acquired led in the end to the design and building of a a lot bigger software of this kind, the drilling barge CUSS I.
Engineering on the CUSS I began early in 1955 and culminated with its eventual completion in late 1956.
The CUSS 1 was the primary drillship within the fashionable sense of the phrase. It was outfitted with 4 rotating thrusters, one at every nook, and was the primary vessel to make use of dynamic positioning. Position monitoring was offered by means of submergible sonar buoys in a round sample across the vessel, from which it acquired alerts in an effort to preserve a footprint of roughly 600 toes in diameter. Manually operated the DP system was advanced and tough to function.
The American Miscellaneous Association (AMSOC) chartered CUSS-I. After some preliminary assessments in tender sediments of a Neogene turbidite basin in waters about 1,000 m deep west of San Diego, the drillship core drilled a gap 600 ft deep in 11,700 ft of water off the Mexican island of Guadalupe. By April 1961 the higher basaltic layer of the deep sea flooring was efficiently drilled.
The entrepreneurial instincts of Bauer got here to the fore as he threw himself into financing new ventures. He succeeded in gaining the assist of Union Oil for his initiatives. On November, 12 1958, Global Marine was based and Bob Bauer turned its first president. CUSS I continued to efficiently drill for the US oil majors like Texaco, Humble Oil SoCal, Shell.
Using all they’d discovered, the Global Marine staff started designing the CUSS II and provides delivery to a completely new era of drillships. CUSS II, renamed Glomar II, was constructed by a Gulf Coast shipyard. The vessel which was nearly twice the dimensions of the CUSS I, set sail in 1962. It was the world’s first drillship constructed as new building.
