“We are honored to be entrusted once again by Golar with this FLNG upgrading contract,” said Marlin Khiew, Executive VP, Energy (Americas), Seatrium. “FLNG Hilli Episeyo is a testament to the strong track record of the projects we have delivered to Golar over the years and reflects their confidence in Seatrium as a partner in the development, conversion and upgrading of high-quality, sustainable, and robust production units.”
Scheduled to enter the yard in the third quarter of 2026, the project involves technical modifications for FLNG Hilli Episeyo’s redeployment. The scope of work includes engineering and procurement of long-lead items, repair and life extension and winterisation of the vessel, as well as the installation of a new soft-yoke mooring system.
When completed, FLNG Hilli Episeyo will be redeployed in the Gulf of San Matias in the Rio Negro province offshore Argentina, liquifying gas from the Vaca Muerta shale formation onshore in Neuquen province for 20 years. FLNG Hilli Episeyo, with a nameplate capacity of 2.45 MMt/year, is set to recommence operations in 2027.
The upgrading of FLNG Hilli Episeyo is part of a broader suite of solutions developed by Seatrium to address the industry’s focus on energy transition, with LNG widely regarded as a transition fuel. FLNG Hilli Episeyo was converted and delivered by the Group in 2017. Seatrium also delivered FLNG Gimi to Golar in 2023, which has recently started commercial operations at the Greater Tortue Ahmeyim Field.
Since its first LNGC drydocking and ship repair in the 1980s, Seatrium has developed extensive expertise in LNG-related cryogenic systems, gaining recognition for the design and build of complex turnkey solutions for vessels that support the entire LNG value chain. Among its key milestones are the development of Singapore’s first LNG bunkering vessel, FueLNG Bellina, in 2021; the creation of the country’s first floating hybrid energy storage system, the Floating Living Lab, which enables sustainable LNG vessel refueling; and the construction of various dual-fuel LNG dredgers and tugs, purpose-built LNG carriers, and LNG-powered containerships.
