QatarEnergy appoints contractor for natural gas liquids train

17 September 2025

QatarEnergy has awarded the main engineering, procurement and construction (EPC) contract for a project to add a fifth natural gas liquids (NGL) train at its NGL complex in Qatar’s Mesaieed Industrial City.

The aim of the project, which is estimated to be worth $2.5bn, is to build a fifth NGL train (NGL-5) with the capacity to process up to 350 million cubic feet a day of rich associated gas from QatarEnergy’s offshore and onshore oil fields.

According to sources, Indian contractor Larsen & Toubro Energy Hydrocarbon (L&TEH) has won the main EPC contract for QatarEnergy’s NGL-5 project.

MEED recently reported that L&TEH – a subsidiary of India’s Larsen & Toubro Group – was the frontrunner to win the project’s main EPC contract, adding that QatarEnergy was expected to issue the official award in September.

The following contractors, among others, were understood to be participating in the project’s main contract tendering process:

  • ⁠CTCI Corporation (Taiwan)
  • L&TEH (India)
  • Samsung E&A (South Korea)
  • ⁠Tecnicas Reunidas (Spain)
  • Tecnimont (Italy)

QatarEnergy issued the expression of interest (EoI) document for the NGL-5 project in early June of last year, with contractors submitting responses by 24 June 2024, MEED previously reported.

QatarEnergy eventually issued the main EPC tender for the NGL-5 project in November 2024.

⁠MEED previously reported that QatarEnergy had received technical bids for the NGL-5 project from contractors by the deadline of 13 April. The client eventually requested that bidders extend the validity of their technical proposals until the end of August, sources told MEED.

MEED also previously reported that contractors had submitted commercial bids for the EPC works on the NGL-5 project by the deadline of 15 June.

Following the submission of commercial bids, QatarEnergy engaged in negotiations with the bidders and requested that they submit revised prices. Contractors submitted revised commercial proposals by 20 July.

In the EoI document, QatarEnergy said that it had commenced site preparation work for the project in the fourth quarter of 2023 and anticipated completion of the work in the first quarter of 2025.

Turkish contractor Iris Insaat was performing the site preparation work, according to regional projects tracker MEED Projects.

Project scope of work

Associated gas from the PS1, PS2 and PS3 offshore fields, as well as the Dukhan onshore field, is processed at existing facilities at the NGL complex in Mesaieed – specifically, the Fahahil stripping plant, NGL-1 and Qapco ethane recovery units.

The planned NGL-5 facility will replace these three units at the Mesaieed complex and process gas from the PS1, PS2 and Dukhan fields.

The scope of work on the project involves EPC on units for the following functions:

  • Feed gas compression
  • Slug handling
  • Gas sweetening
  • Dehydration
  • Mercury removal
  • NGL fractionation
  • NGL recovery
  • Product treatment
  • Propane refrigeration
  • Acid gas enrichment
  • Sulphur recovery
  • Anti-flaring
  • Utilities
  • Boil-off gas recovery
  • Drains and collection networks
  • Effluent water treatment plant
  • Carbon dioxide treatment and sequestration/export
  • Brownfield modifications
  • Product rundown pipelines

QatarEnergy intends to start operations at the NGL-5 facility by the second quarter of 2028.
