Adnoc Gas has awarded contracts worth a total of $550m for two engineering, procurement and construction (EPC) packages of its sales gas pipeline network upgrade project, also known as Estidama.
The combined packages four and seven of the Estidama project were awarded to the UAE unit of Oman's Galfar Engineering & Contracting. The value of the contract is understood to be about $295m.
Abu Dhabi’s NMDC Energy has won package six. The value of the contract is $255m, NMDC Energy said in a filing with the Abu Dhabi Securities Exchange.
The main scope of work on Estidama Package 4+7 involves laying a new pipeline from the Al-Shuwaib pig launcher and pig receiver station in Abu Dhabi to the Sajaa gas facility in the emirate of Sharjah.
The scope also covers building a new gas pipeline between BVS-2/KP28.7 in Abu Dhabi and Dubai’s Margham gas facility, to meet increased demand from Adnoc Gas’ customer Dubai Supply Authority (Dusup).
The EPC scope of work on Estidama Package 6 entails the installation of a 52-inch, 74-kilometre (km) pipeline from Sweihan to Al-Shuwaib in Abu Dhabi, and building two block valve stations.
Adnoc Gas received technical and commercial bids for package six and the combined packages four and seven in 2022 and 2023, respectively.
Contractors submitted technical bids for package six in August 2022 and commercial bids by 21 November of that year.
Contractors submitted technical bids for the combined packages four and seven by 27 March last year, and commercial bids by 9 August.
in late May, MEED reported that Adnoc Gas had asked contractors to extend the validity of their bids for the two packages until 30 June. This was the latest in a series of bid validity extension requests made by the project operator.
Estidama scheme
Adnoc Gas, the natural gas producing and processing subsidiary of Abu Dhabi National Oil Company (Adnoc) has made significant progress with the Estidama project, which will enhance Adnoc’s sales gas pipeline network across the UAE. The objective of the scheme is to cater to rising demand for gas from industrial consumers, particularly in the Northern Emirates.
Through the Estidama scheme, Adnoc Gas aims to extend the existing 3,200km pipeline network to over 3,500km, enabling the transportation of higher volumes of natural gas to customers across the UAE.
EPC works on the estimated $2bn-plus Estidama project have been divided into seven packages.
China Petroleum Pipeline Engineering performed the Estidama project’s front-end engineering and design works as part of a contract worth about $6m that Adnoc Gas Processing awarded to the Chinese state-owned firm in October 2020.
MEED reported in December 2021 that Abu Dhabi-based contractor Integrated Specialised General Contracting Company (Iscco) had won package one of the project, which is understood to have a contract value of $18m. Iscco later sub-contracted the detailed engineering works on package one to the Abu Dhabi branch of Sweden-headquartered consultancy Rejlers.
In July 2023, Adnoc Gas awarded the EPC contract for package two, estimated to be worth $720m, to UK-based Petrofac, and package three, valued at $630m, was won by a consortium of NMDC Energy and Lebanon’s CAT Group.
Separately, Adnoc Gas received technical bids from contractors for package five of the Estidama project on 24 June, MEED reported. Package five was previously part of package two but was later split off and tendered as a separate package by Adnoc Gas.
The scope of work on package five involves EPC works to upgrade the Habshan gas processing complex in Abu Dhabi.
MEED also recently reported that contractors were preparing technical bids for package eight of the Estidama scheme, which involves building a new pipeline that will transport gas as feedstock from the Habshan gas processing complex in Abu Dhabi to its upcoming liquefied natural gas terminal in Ruwais. The proposed pipeline will cover about 190km and will be built in two sections.

Read the February 2026 MEED Business Review2 February 2026
Download / Subscribe / 14-day trial access After years of cautious capital discipline, upstream oil and gas spending is gathering pace across the Middle East and beyond, with 2026 shaping up to be a statement year for investment.
In the Middle East and North Africa (Mena) region, oil companies are pushing ahead with projects deemed critical to long-term energy security, even as oil prices soften. Gas and LNG developments are taking an increasingly prominent role, reflecting rising power demand and the search for lower-carbon fuels.Globally, North America is set to lead upstream spending through to 2030, but the Middle East remains a close follower, underpinned by low-cost reserves and expanding infrastructure. Read more about what’s driving the next wave of upstream investment here.
Meanwhile, February’s market focus covers Qatar, where Doha is beginning to reap the rewards of its long-term gas investment, strategic spending and diplomatic efforts.
This edition also includes MEED’s latest ranking of GCC water developers. In this package, we look at how the water sector has regained momentum, as the value of public-private partnership and engineering, procurement and construction (EPC) contract awards for Mena water infrastructure schemes reached a record level in 2025.
In the latest issue, we also examine how Iran's recent protests have elevated regional uncertainty, and reveal that GCC contract awards declined by almost a third in 2025. The team also speaks to Mohamed Youssef of AtkinsRealis about demand drivers and challenges for the Canadian EPC specialist; discusses projects market resilience with US engineering firm Parsons' Pierre Santoni; and highlights how DP World underpins Dubai’s economic growth strategy.

Turner & Townsend to manage Rak Central construction2 February 2026
UK-based Turner & Townsend has been appointed to provide project management services for the Rak Central mixed-use development in the UAE’s northern emirate of Ras Al-Khaimah.
Rak Central features residential and commercial districts.
The project will be developed in phases.
The first phase includes 1 million square feet of commercial office space. It also involves developing 34 residential plots, which will be offered to developers to build residential towers up to 45 storeys.
The development will comprise three hotels offering more than 1,000 keys and 4,000 residential apartments across five interconnected buildings.
The first phase is set to open in 2027.
It is being constructed on Sheikh Mohammed Bin Salem Al-Qasimi Street.
In September last year, Ras Al-Khaimah-based master developer Marjan appointed Dubai-based firm Alec as the main contractor for its new headquarters and a mixed-use office complex at Rak Central.
The complex has been designed by US-based architectural firm Gensler.

Adnoc Refining negotiates with naphtha upgrade bidders2 February 2026

The refining business of Abu Dhabi National Oil Company (Adnoc Refining) is in negotiations with contractors that submitted bids for a key project to maximise naphtha production from its Abu Dhabi refineries.
Adnoc Refining produces approximately 11 million tonnes a year (t/y) of naphtha, which is categorised into two types: crude naphtha, produced from crude processing in the refineries; and condensate naphtha, obtained from processing condensates.
The project aims to upgrade Adnoc Refining’s naphtha output to more valuable gasoline products, thereby increasing its overall refinery margin.
MEED previously reported that contractors had submitted commercial proposals for the naphtha upgrade project by 24 December.
Since receiving commercial bids, Adnoc Refining has been in commercial negotiations with bidders since January, although no contractor is believed to have emerged as a frontrunner to win the contract, sources told MEED.
According to sources, Adnoc Refining is seeking a target price of $700m, with bidders asked to match that figure. “At this point, the situation is fluid, and there is room for change. Expect flexibility from both sides [project operator and bidders] in the price negotiation process,” one source said.
Adnoc Refining issued the main tender for engineering, procurement and construction (EPC) works on the project in May last year. Contractors that submitted technical bids for the project in June are thought to include:
- Archirodon (Greece)
- Enppi (Egypt) / Petrojet (Egypt)
- Kalpataru Projects International (India)
- Larsen & Toubro Energy Hydrocarbon (India)
- Petrofac (UK)
- Tecnimont (Italy)
Following the submission of technical bids, Adnoc Refining engaged bidders in a series of technical clarification meetings, sources previously told MEED.
Kalpataru Projects International was later disqualified from the tendering exercise by Adnoc Refining, as per sources.
Adnoc Refining then issued a notification on 4 December to contractors bidding for the contract, requesting that they submit commercial bids by 24 December.
The main scope of work for the project is to develop an integrated naphtha-producing complex comprising light and heavy naphtha hydrotreater units, light naphtha isomerisation units, two heavy naphtha reformer units and a 50,000-barrel-a-day (b/d) continuous catalytic reformer.
Separately, Adnoc Refining has stipulated that licensed process technology from France-based Axens will be deployed to operate the units.
The naphtha upgrade project being advanced by Adnoc Refining is separate from another project being undertaken by the operator to convert incremental volumes of its naphtha output into commercially valuable jet fuel. MEED recently reported that Adnoc Refining awarded a feed contract for the project to Engineers India Limited (EIL).
Feed-to-EPC contest
Adnoc Group owns the majority 65% stake in Adnoc Refining, with Italian energy major Eni and Austria’s OMV owning 20% and 15% stakes, respectively, as a result of a $5.8bn transaction completed in 2019.
Adnoc Refining has a total refining capacity of 922,000 b/d of crude oil and condensates. The company produces over 40 million t/y of refined products, such as liquefied petroleum gas, naphtha, gasoline, jet fuel, gas oil, base oil, fuel oil and petrochemicals feedstocks such as propylene. The company’s specialty products include carbon black and anode coke.
Adnoc Refining had started a front-end engineering and design (feed)-to-EPC competition for the naphtha upgrade project in March 2024, MEED previously reported, selecting UK-headquartered Petrofac and South Korea’s GS Engineering & Construction to participate in the feed-to-EPC contest for the project.
The project operator eventually cancelled the feed-to-EPC competition, sources told MEED. The reason for the cancellation could be that “prices that were submitted by the bidders were above budget”, a source said.
However, the EPC tender issued by Adnoc Refining for the naphtha upgrade project is understood to be based on the feed submission by Petrofac, according to sources.
The naphtha upgrade project itself is a leaner version of an estimated $3bn-plus project undertaken by Adnoc Refining a few years ago to develop a large-scale refining facility with the capacity to produce 4.2 million t/y of gasoline and 1.6 million t/y of aromatics.
Adnoc Refining cancelled the gasoline and aromatics project in 2019. The operator has “retained some elements and units that were meant to be developed” in the ongoing naphtha upgrade project, a source previously said.

Saudi Arabia tenders Al-Ula wellfield expansion contract2 February 2026
Saudi Arabia’s Water Transmission Company (WTCO) has opened bidding for an engineering, procurement and construction (EPC) contract to develop and expand the Sharaan wellfield in Al-Ula, in Medina province.
The submission deadline is 15 February.
The project is divided into two stages. The pre-expansion phase covers upgrading and rehabilitation works at 13 existing operating groundwater wells.
This includes replacing diesel generators at the PS1 pump station, upgrading the fuel system and carrying out electrical retrofitting across all wells.
Each well will be equipped with a dedicated generator to allow continuous, autonomous 24-hour operation.
The expansion phase, covering phase one only, includes drilling eight new production wells and one observation well. It also includes the construction of a 5,000-cubic-metre ground-level storage reservoir.
Additional works include installing two high-capacity pumps and developing a carbon steel pipeline network integrated with PS1 to deliver the full design flow.
According to the tender notice, contractors must demonstrate experience in groundwater well drilling, power generation systems, electrical and mechanical works, pump stations and water transmission networks.
WTCO is also moving forward with procurement for the Ras Mohaisen-Baha-Mecca and Jubail-Buraidah independent water transmission system projects under the public-private partnership model.
The state-owned water utility said qualified EPC contractors have until 5 February to submit technical and financial bids for the 542,000-cubic-metres-a-day Ras Mohaisen project.
The bid submission deadline for the 348-kilometre-long Jubail-Buraidah project was 1 February.

Riyadh qualifies five groups for One-Stop Stations PPP2 February 2026
Register for MEED’s 14-day trial access
Saudi Arabia’s Roads General Authority (RGA), in collaboration with the National Centre for Privatisation & Public-Private Partnership (NCP), has qualified five groups for a contract to develop the kingdom’s One-Stop Station project on a public-private partnership (PPP) basis.
The groups include:
- Al-Ayuni Investment & Contracting Company / Al-Jeri
- IC Ictas / Algihaz Holding / Al-Drees
- TechTrade Global / Al-Habbas / Fuelax / Markabat / Naqleen Company
- Petromin / Red Sea Housing
- Asyad / Sasco
The project includes the development of facilities at several locations across the RGA’s 73,600-kilometre intercity road network.
The facilities include refuelling stations, commercial outlets, parking lots, driver rest areas, vehicle maintenance centres and other hospitality amenities.
The project will be implemented under a 30-year design, build, finance, operate and maintain (DBFOM) contract, and will be tendered in three waves comprising six packages.
The first wave will include the initial package, the second wave will encompass the second and third packages, and the third wave will cover the remaining three packages.
In August last year, 49 Saudi and international firms expressed interest in the contract to develop the kingdom’s One-Stop Station project, as MEED reported.
In January, Saudi Arabia launched a National Privatisation Strategy, which aims to mobilise $64bn in private sector capital by 2030.
The strategy was approved by Saudi Arabia’s Minister of Finance and chairman of the National Centre for Privatisation (NCP), Mohammed Bin Abdullah Al-Jadaan.
The strategy builds on the privatisation programme, which was first introduced in 2018. It will focus on unlocking state-owned assets for private investment and privatising selected government services.
The value of PPP contracts in Saudi Arabia has risen sharply over the past few years as the government seeks to develop projects through the private sector and diversify funding sources
PPPs have been used in Saudi Arabia and the wider GCC region for over two decades, but have primarily been limited to power generation and water desalination projects, where developers benefit from guaranteed take-or-pay power purchase agreements that eliminate demand risk.
As capital expenditure continues to increase, the NCP is expected to add dozens more PPPs to its future pipeline to reduce the state’s financial burden and stimulate private sector involvement in the local projects market.
