Today’s Transocean is the modern descendant of the world’s most innovative and successful deepwater drilling companies, and the pioneering people who made them good.
A Legacy of Bold Leadership
For generations Transocean and its legacy companies have led the offshore drilling industry with the most innovative and sophisticated technology, and the people that waterput it to record-setting use. From the very first mobile jackup equipment and the very first drillship, both ter the 1950s, to the 2018 drillships that incorporate our designed and patented Active Power Compensation®, hybrid system, wij’re are still pushing the curve.
Transocean traces its roots to onshore drilling operations, where T.S. “Stoney” Stoneman began his career spil a draftsman and then a landman before joining the Danciger Oil & Refining Company of Fort Worth, Texas te 1926.
Mr. Stoneman bought the company’s very first drilling equipment, paying for it with a private check and putting it on his expense report. He would zometeen play key leadership roles ter pioneering offshore drilling with The Offshore Company.
While the very first tentative steps to developing the marine drilling industry were being taken ter the 1930s, drilling engineers were advancing onshore drilling methods and equipment.
While Danciger’s T.S. Stoneman, shown ter the photo above, continued his successful land career te the United States, Raymond Godet, an engineer who would zometeen be a leader te another legacy company, Forex, wasgoed busy ter France. Mr. Godet bought a German drilling equipment te Paris and hooked it up to a boiler from a steam engine, enabling the equipment to drill land wells at Saint Marcet.
Several legacy Transocean entities emerged ter the 1940s when the following companies were formed.
- 1942 – Forex wasgoed established te France
- Santa Fe Drilling Company wasgoed established. Joe Robinson, a Union Oil Company drilling superintendent, and 61 drilling department employees waterput up $250,000 of their own money and borrowed $600,000 to buy the business from Union Oil. Santa Fe began drilling wells onshore ter California ter 1947. Te less than two years, the loan wasgoed paid ter total.
- The CUSS group wasgoed formed. This consortium of Continental Oil Company, Union Oil Company of California, Superior Oil Company and Shell Oil Company established the feasibility of drilling offshore. The CUSS group zometeen evolved into Integral Marine.
An significant decade of innovation including the introduction of the world’s very first mobile jackup drilling equipment and the very first drillship ushered te fresh operations.
- 1950 – Southern Production Co., a subsidiary of Southern National Gas, purchased Danciger and zometeen began work to form The Offshore Company.
- 1953 – The Offshore Company wasgoed created to vormgeving and build Equipment 51 (shown ter photo), the world’s very first mobile jackup drilling equipment.
- 1954 – The Offshore Company launched Equipment 51. A fresh pneumatic jacking system raised the unit’s gams at one drilling location so that the equipment could be moved to the next where the gams were lowered to the seafloor. At that point, the equipment’s deck wasgoed elevated above the sea surface.
- 1955 – Sedco began operations with two, shallow-water semisubmersible barges te South Texas and built Equipment 21, the very first “post-type” swamp barge.
- Mundial Marine Drilling Company commissioned the CUSS I, the very first drillship. This equipment pioneered early versions of deepwater drilling methods and technology used by today&rsquo,s offshore drilling fleet.
- Santa Fe entered the offshore drilling business with a contract te Trinidad using a land equipment adapted to a jackup barge and provided crews for a drillship offshore California.
Oil and gas discoveries continued to drive growing request for offshore drilling services during the 1960s, requiring extensive caudal investments for fresh equipments and equipment.
- 1960 – Santa Fe became a public company with shares sold through the OTC Market. It expanded drilling operations from the U.S. to Australia and the Pacific.
- 1962 –
- Glomar II (shown ter photo) began operations spil the very first ship-shaped barge equipment constructed spil a newbuild unit. She wasgoed also the very first self-propelled drillship to drill ter Alaska’s Cook Inlet and wasgoed zometeen used te the Pacific ter studies to evaluate mining of manganese nodules spil part of the Deep Ocean Mining Project. The Cuss-class drillships names were switched this year from Cuss to Glomar.
- Neptune Offshore wasgoed founded with caudal from Forex and Languedocienne-Forenco.
During this decade, Transocean legacy companies continued to pioneer dynamic positioning (Double penetration) and other marine technology, enabling equipments to budge inbetween wells and stay on drilling locations using thrusters.
- 1971 – The Sedco 445 became the very first modern self-propelled drillship. The equipment straks wasgoed called the Deepwater Navigator.
- 1973 – Mundial Marine designed and built the Hughes Glomar Explorer (shown ter photo). The unit wasgoed contracted to the CIA for a secret mission, reported ter the news media to be the recovery of a sunken Soviet submarine. It wasgoed retrofitted straks spil the Glomar Explorer and ultimately spil the ultra-deepwater drillship GSF Explorer.
- 1977 – The Glomar Pacific drillship wasgoed placed into service, utilizing even more advanced Double penetration technology along with the most up-to-date naval architecture and marine engineering.
- 1979 – The very first Double penetration semisubmersible, Sedco 709, made its inicio.
Innovative drilling technology during this period led to fresh operations te offshore frontier areas, while mergers and acquisitions integrated some of the most experienced offshore drilling teams ter the business.
- 1981 – The Kuwait Petroleum Corporation (KPC) acquired Santa Fe.
- 1982 – The Offshore Company became Sonat Offshore Drilling Inc.
- 1984 – Schlumberger purchased Sedco.
- 1985 –
- Sedco and Forex Neptune were combined into the Sedco Forex drilling division of Schlumberger.
- The world&rsquo,s initial fourth-generation semisubmersible equipment, Polar Pioneer (shown ter photo), made its comienzo ter Norway.
Transocean’s legacy companies achieved milestones that included the introduction of the latest generations of drilling equipments, a major safety achievement and integration through various transactions.
- 1993 – Ter May, Sonat, Inc. spun-off Sonat Offshore Drilling Inc., at which time Sonat Offshore Drilling Inc. (Equipment) became its own entity and began trading on the Fresh York Stock Exchange.
- 1996 –
- Ter September, Sonat Offshore Deepwater Drilling Inc. acquired Transocean ASA. At this time the company name wasgoed switched to Transocean Offshore Deepwater Drilling Inc. and the logo wasgoed switched.
- Te December, Falcon Drilling Company became a publicly-traded company.
- Santa Fe celebrated its 50th anniversary.
- The Transocean Leader became the world&rsquo,s very first fourth-generation semisubmersible capable of year-round operations westelijk of the Shetland Islands te more than Four,000 feet of water.
Three of the largest mergers te the company’s history occurred ter the 2000s. The company’s ultra-deepwater and harsh environment floaters also made their mark with a string of world records.
- 2001 – Transocean Sedco Forex Inc. and R&B Falcon Corporation combined to form the world’s largest offshore drilling contractor.
- 2001 – Universal Marine and Santa Fe International merged to become GlobalSantaFe Corporation, the 2nd largest drilling contractor.
- 2007 – Transocean and GlobalSantaFe merged spil the world’s largest offshore drilling contractor.
Ter addition, the company’s ultra-deepwater drilling equipments made their mark ter the 2000s with a string of world records, including:
- 2001 –
- Discoverer Spirit &ndash, 7,209 feet of water, subsea completion record.
- Deepwater Expedition &ndash, 9,144 feet, water depth record.
- Deepwater Millennium &ndash, 9,200 feet, water depth record.
- Discoverer Spirit &ndash, 9,687 feet, water depth record.
- Discoverer Spirit &ndash, 9,727 feet, water depth record.
During the current decade, Transocean has continued to set world deepwater drilling records while upgrading our high-specification fleet.
