Kanuni (drillship)

Kanuni (ex "NS37/ Sertão") is a Turkey-flagged sixth-generation ultra deepwater drillship owned and operated by the Turkish Petroleum Corporation. She is Turkey's third drillship.
Name.
Kanuni means "law-related", "legal" in Turkish and can be used in a wider range of related meanings. The word derives from Arabic قَانُون (qānūn), which comes from Ancient Greek κανών (kanṓn).
The three drillships of the state-owned Turkish gas company, Fatih, Yavuz and Kanuni, are named after the most famous conquerors and rulers of the Ottoman Empire: Mehmed I, Turkish: Fatih Sultan Mehmet, Mehmed the Conqueror, who conquered Constantinople in 1453; Selim I (r. 1512-1520), known as Selim the Resolute, Turkish: Yavuz Sultan Selim, who hugely expanded his empire; and Suleiman the Magnificent (r. 1520-1566), known in Turkish as Kanunî Sultan Süleyman ("the Lawgiver"), under whom the empire reached its apex.
History.
The ship was built in three years by Samsung Heavy Industries, Geoje, South Korea, and finished in 2012, and christened "Sertão". She was worth around US$600 million. Owned by Schahin Petroleum Gas in Rio de Janeiro, Brazil, and flagged Marshall Islands with home port Majuro, she served for the Brazilian state-owned Petrobras between 2012 and 2015.
After the Schahin Group went bankrupt in April 2015, the U.S.-based Dleif Drilling became the new owner. The vessel then sailed from Brazil to Teesside, North East England, where she was arrested by the Admiralty court. The arrest of the vessel occurred to force the payment of the owner's debt. Dleif Drilling tasked the Dutch offshore consulting company Okeanos BV and the ship management company V-Ships Cyprus with PB Consultants Ltd from Scotland offshore brokering and advisory company Pareto Offshore AS of Norway to find a future employment. The vessel was then listed for sale. A purchase offer for the vessel in amount of US$75 million was rejected by late November 2016. In 2017, her name was changed to "NS37 / Sertão".
After the vessel was idled and warm stacked for nearly two years, the Admiralty Marshal of the United Kingdom opened a request for tender in mid January 2020 that was run by the broker CW Kellock & Co. Ltd. The state-owned Turkish Petroleum Corporation, TPAO acquired the drillship for US$37.5 million winning the bidding. Renamed "Kanuni", she arrived in the territorial waters of Turkey in Eastern Mediterranean on 13 March 2020 after her 18-day journey departing from Port Talbot in Wales, United Kingdom. "Kanuni" is the third drillship of Turkey after "Fatih" (ex "Deepsea Metro II") and "Yavuz" (ex "Deepsea Metro I").
