Contractor progresses with Qatar LNG decarbonisation project

30 October 2025

Engineering, procurement and construction (EPC) works are progressing on an estimated $2bn to $2.5bn carbon dioxide (CO2) sequestration complex project of QatarEnergy LNG covering its liquefied natural gas (LNG) production operations in Qatar’s Ras Laffan Industrial City (RLIC).

Once commissioned, the planned sequestration facility will be capable of capturing 4.3 million tonnes a year (t/y) of CO2 from QatarEnergy LNG’s production operations in RLIC.

QatarEnergy LNG, a subsidiary of state enterprise QatarEnergy, awarded the main EPC contract for the CO2 sequestration project to South Korean contractor Samsung C&T, sources told MEED.

The letter of award for the EPC contract was issued by QatarEnergy LNG to Samsung C&T on 27 May, according to a source.

The following contractors are among those that are understood to have submitted bids in April for EPC works on the QatarEnergy LNG CO2 sequestration project:

  • Chiyoda (Japan) / Consolidated Contractors Company (Greece/Lebanon)
  • Larsen & Toubro Energy Hydrocarbon (India)
  • Samsung C&T (South Korea)

Based on the initial evaluation of bids, Larsen & Toubro Energy Hydrocarbon is understood to have pulled ahead in the race for the project’s contract, MEED previously reported. However, sources, at the time, added that the situation could change.

QatarEnergy LNG awarded Australia-headquartered consultancy Worley a contract in September 2023 to execute the front-end engineering and design (feed) work on the project and to prepare the EPC scope of work.

CO2 sequestration facility

The planned sequestration facility will capture CO2 from seven LNG trains at the QG North complex and three LNG trains at the QG South complex.

The CO2 captured from the trains is to be dehydrated, compressed and transferred via a new 154-kilometre pipeline, to be injected into wells at the Dukhan oil field development onshore Qatar for a related enhanced oil recovery pilot scheme.

The pilot project is part of QatarEnergy’s long-term strategy for the redevelopment of the Dukhan fields that will contribute to the recovery of additional crude.

The detailed EPC scope of work on the CO2 sequestration project covers the following:

  • QG North complex:
    • Installation of four new electric-driven compressors
    • New power substation for power import from Kahramaa 65MW
    • New ITR for DCS/ESD/F&G
    • Tie-ins with utility units
    • Dehydration package
    • Pig launcher
       
  • QG South complex:
    • Installation of two new electric-driven compressors
    • Integration with South injection system unit 85
    • Solvent reformulation for South trains 1/23
    • New power substation for power import from Kahramaa 35MW
    • New SIH for DCS/ESD/F&G
    • Tie-ins with utility units
    • Dehydration package
    • Chillers package
    • Pig launcher
       
  • RLIC corridors
    • Common 22-inch export pipeline stretching 18 kilometres
    • Power tie-in RLF3 with Kahramaa
    • Electric cables
    • Fiber optic cable
       
  • Lot W15
    • Six injection wells by QatarEnergy LNG subsurface
    • Six injection flowlines and metring skid
    • Six wellhead control panels
    • Power tie-in from Barzan
    • Substation
    • Pig receiver
    • Access road and fencing

The project will directly reduce CO2 emissions because some of the CO2 injected into wells at the Dukhan oil field will remain in the reservoir after injection.

The CO2 sequestration complex in RLIC is expected to start operations by the end of 2027.

North Field LNG expansion

Meanwhile, QatarEnergy LNG continues to press forward with its North Field LNG expansion programme.

The estimated $40bn North Field LNG expansion programme aims to raise Qatar’s total LNG production capacity from 77.5 million t/y to 142 million t/y in three phases.

QatarEnergy is understood to have spent almost $30bn on the two phases of the North Field LNG expansion programme, North Field East and North Field South, which will increase its LNG production capacity from 77.5 million t/y to 126 million t/y by 2028.

EPC works on the two projects are making progress.

QatarEnergy awarded the main EPC contracts in 2021 for the North Field East project, which is projected to increase LNG output to 110 million t/y by this year. The main $13bn EPC package, which covers the engineering, procurement, construction and installation of four LNG trains with capacities of 8 million t/y each, was awarded to a consortium of Japan’s Chiyoda Corporation and France’s Technip Energies in February 2021.

QatarEnergy awarded the main EPC contract for the North Field South LNG project, worth $10bn, in May 2023. The contract covers two large LNG processing trains, each with a capacity of 7.8 million t/y, and was awarded to a consortium of Technip Energies and Lebanon-based Consolidated Contractors Company.

When fully commissioned, the first two phases of the North Field LNG expansion programme will contribute a total supply capacity of 48 million t/y to the global LNG market.

In February 2024, QatarEnergy announced the third phase of its North Field LNG expansion programme. To be called North Field West, the project will further increase QatarEnergy’s LNG production capacity to 142 million t/y when it is commissioned by 2030.

The North Field West project will have an LNG production capacity of 16 million t/y, which is expected to be achieved through two 8 million t/y LNG processing trains, based on the two earlier phases of QatarEnergy’s LNG expansion programme. The new project will draw feedstock for LNG production from the western zone of Qatar’s North Field offshore gas reserve.

The state enterprise recently started a prequalification process for the main tendering exercise for dredging works on the North Field West project.
