MT Botaş FSRU Ertuğrul Gazi
MT Botaş FSRU Ertuğrul Gazi is a South Korean-built Turkey-flagged offshore support vessel certified as a floating storage regasification unit (FSRU) for liquified natural gas (LNG). She is owned by the Turkish petroleum and natural gas pipeline corporation BOTAŞ, and operated by the Norwegian maritime company Wilhelmsen Ship Management, serving at Botaş Dörtyol LNG Storage Facility in southern Turkey. This is the country's first vessel of this type. History 
The offshore support vessel was built for the Turkish petroleum and natural gas pipeline corporation BOTAŞ, at a budget cost of US$225 million, at Ulsan shipyard of Hyundai Heavy Industries. Testing of the vessel started after her launch on 2 September 2020. She was completed on 17 March 2021 after a delay of six months, and sailed to Turkey on 23 March. She is certified as a Floating Storage Regasification Unit (FSRU) for liquified natural gas (LNG) in accordance with the guidelines for LNG Regasification Vessels of the classification society American Bureau of Shipping (ABS). She was named Ertuğrul Gazi after Ertuğrul (died c. 1280/1281), who was the father of Osman I (), founder of the Ottoman Empire. FSRU Ertuğrul Gazi is the country's first vessel of this type. The ship arrived in Dörtyol, Hatay Province, southern Turkey on 26 April 2021. Her home port is Istanbul, Turkey. She then undergwent final regasification trials on site. On 25 June the same year, she was commissioned at Botaş Dörtyol LNG Storage Facility, northeastern Mediterranean Sea replacing the chartered Bahamas-flagged MT MOL FSRU Challenger, the world's largest FSRU. She started her operations under the management of the Singapore-based Norwegian company Wilhelmsen Ship Management, transferring  Algeria-based LNG from the Bahamas-flagged carrier LNG Berge Arzew and regasifying and pumping into the national pipeline network system on 29 June. In 2022, BOTAŞ reported that the FSRU carried out a total of 24 ship-to-ship operations within twelve months. She transferred  of regasified natural gas into the national pipeline network system in one year, which is equivalent to about the six-months housing consumption of natural gas of Istanbul, which has a population of around 18.4 million.
