US LNG-producing giant Cheniere Energy has taken up the two one-year optional periods on three LNG carriers owned by John Fredriksen’s Flex LNG, extending the ships charters through to 2027 as charterers move to snap up tonnage in an ever-tightening market.

In addition, Flex and the arm of US company Cheniere Marketing International (CMI) have agreed new firm and optional periods on two of the vessels, which give the charterer the ability to extend the hire into 2033.
