Biography Family Fredriksen was born on 10 May 1944 to a welder and his wife, and grew up in Etterstad, in the eastern half of Oslo. Fredriksen is a widower and has two twin daughters: Cecilie and Kathrine Astrup Fredriksen (both born 1983). Fredriksen's late wife, dentist Inger Astrup Fredriksen (died 2006), originally belonged to one of the Astrup families in Norway. Her father was a professor of psychiatry, and her grand uncle was the painter Nikolai Astrup. Business Frederiksen first got into oil trading in the 1960s in Beirut, Lebanon, before buying his first tankers in the 1970s. He made his fortune during the Iran–Iraq War in the 1980s, when his tankers picked up oil at great risk and huge profits. As described by his biographer, "he was the lifeline to the Ayatollah." Fredriksen would later become the world's largest tanker owner, with more than seventy oil tankers and major interests in oil rigs and fish farming. His fleet is dominated by costly double-hulled, environmentally safer tankers. In 2006, Seadrill bought more than 50 percent of Smedvig, gaining control of the company (51.24 percent of the votes and 52.27 percent of the capital). Smedvig is Fredriksen's biggest ever deal. Noble Corp sold its stake to Seadrill in 2009, leaving Seadrill with full control. Fredriksen has been the majority owner of Vålerenga I.F. for many years. Fortune The
