John Fredriksen-led Flex LNG made its debut on the New York Stock Exchange on Monday.
Chief executive Oystein Kalleklev rang the opening bell to mark the start of what is a dual listing for Flex, which is also listed on the Oslo Stock Exchange.
Flex's stock, which is trading on both exchanges under the FLNG ticker, opened at $11.00 climbing to a high of $11.30 before closing at $11.21.
Kalleklev said the NYSE listing comes 15 years to the day after Fredriksen's Ship Finance International (SFL) went public on the NYSE.
"Flex LNG joins SFL as well as Frontline and Golden Ocean as US listed shipping companies in the Seatankers Group," he said.
Flex boasts a fleet of 13 LNG carriers, five of which are trading.
A sixth newbuilding, the 173,400-cbm Flex Courageous, is due for delivery in August, with five more vessels due for handover in 2020 and a further two the following year.
