The timing of the giant floating facility's return to operation coincides with peak consumption in major markets including China and Europe as the northern hemisphere winter drives demand, though high inventories and generally mild weather have limited buying so far this year.
Shell, which began extensive maintenance at the facility in August, declined to comment. It said last month that it expected the plant to ramp up production in December.
A Shell tanker, the 174,000 cubic metre Orion Bohemia, is circling near the plant, ICIS LNG ship-tracking data shows. If it loads from Prelude, it will be the first vessel to do so since Aug. 8.
Prelude, the deck of which is longer than four soccer fields, has suffered several outages since it started production in June 2019, including a fire that led to a full power loss in December 2021.
Reuters reported in September that Shell considered shutting Prelude for a year to fix issues but instead opted for a shorter maintenance period.
