In 1985, Noble Affiliates, Inc., completed the corporate spin-off of Noble Drilling Corporation. In 2002, the company underwent a restructuring whereby it moved its domicile to the Cayman Islands and established Noble Corporation as the parent holding company. In early 2009, the company moved its domicile from the Cayman Islands to Switzerland due to the potential for more U.S. taxes on Caribbean tax havens. In 2013, the company moved to the United Kingdom. In 2010, the company acquired Frontier Drilling in a $2.16 billion cash transaction. In 2014, the company distributed its interests in Paragon Offshore plc to its shareholders. In July 2020, the company filed for bankruptcy; it emerged from bankruptcy in February 2021. In April 2021, the company acquired Pacific Drilling. In November 2021, it was announced that Maersk Drilling would merge with Noble Corporation and the combined company would be called Noble Corporation, with a valuation of £2.6 billion. The merger was completed on October 3, 2022. Accidents and incidents
In 2012, the Noble Discoverer drillship, operating under contract for Shell lost its mooring and drifted close to shore. There were no injuries or environmental damage reported as a result of the accident. In 2017, an employee went missing on the Noble Lloyd Noble drilling rig. References
