Adnoc Gas receives contractor prices for Ewec sales pipeline

13 August 2026

 

Contractors have submitted bids to Adnoc Gas for a new pipeline that it plans to build to supply gas from the Habshan scraper launcher station at its Habshan gas compression complex to the Al-Nouf customer receiving station (CRS), for delivery to Emirates Water & Electricity Company (Ewec).

The proposed 56-inch pipeline, stretching 127 kilometres, will help the UAE’s state utility, Ewec, meet additional gas demand to power the second phase of an artificial intelligence (AI) data centre in Abu Dhabi, as well as to support the relocation of some of its key assets in the Mirfa area of the emirate.

Adnoc Gas, the natural gas processing business of Abu Dhabi National Oil Company (Adnoc Group), issued the tender in mid-April for the project, officially titled ‘Ewec Mirfa relocation + AI data centre phase 2: Habshan to Al-Nouf pipeline’.

Contractors submitted technical bids for the project in late May, while commercial bids were submitted on 3 August, sources told MEED.

According to sources, the following contractors, among others, are understood to have submitted bids:

  • Arkad Engineering & Construction (Saudi Arabia; part of Italy’s Arkad SpA)
  • China Petroleum Pipeline Engineering (China)
  • Galfar Emirates (UAE branch of Oman’s Galfar Engineering & Construction)
  • Kalpataru Projects International (India)

China Petroleum Pipeline Engineering has performed front-end engineering and design (feed) work on the project.

The planned pipeline will provide two sales-gas streams to Ewec: 600-660 million cubic feet a day (cf/d) for AI data centre phase 2, and 650-715 million cf/d for the Mirfa relocation project.

The core elements of the project involve engineering, procurement and construction (EPC) of the main Habshan-to-Al-Nouf pipeline and the following associated units:

  • 56-inch scraper (pig) launcher (607-V-604) and associated hot tap
  • Four block valve stations (BVSs -637-BVS-01/02/03/04)
  • 56-inch scraper (pig) receiver (848-V-101)
  • CRS at Al-Nouf including sales gas filters, pressure regulating stations (PRS), custody transfer metering systems (CTMS)
  • 30-inch tapping to Ewec plants (cold tie-ins)
  • 52-inch tie-ins between Adnoc Gas’ Maximise Ethane Recovery & Monetisation (Meram) project and package 3 of its broader project to upgrade its sales gas pipeline network across the UAE, also known as Estidama.
Adnoc Gas business

Adnoc Group announced the creation of Adnoc Gas through the merger of its subsidiaries Adnoc Gas Processing and Adnoc LNG in November 2022. Adnoc Gas began operating as a commercial entity on 1 January 2023.

The consolidation of Adnoc’s gas processing and liquefied natural gas (LNG) operations into Adnoc Gas has created one of the world’s largest gas-processing entities, with a processing capacity of about 10 billion standard cubic feet of gas a day at eight onshore and offshore sites, which include its Asab, Bab, Bu Hasa, Habshan and Ruwais plants.

The company also owns a 3,250km gas pipeline network to supply feedstock to its customers in the UAE. This sales gas pipeline network is being expanded to over 3,500km through the estimated $3bn Estidama project.

At present, the network delivers sales gas to Adnoc Group companies, Ewec, Dolphin Energy, Emirates Global Aluminium (EGA), and other industrial consumers in Abu Dhabi, Dubai, Sharjah and the Northern Emirates.

The main critical facilities and/or manifolds of the Adnoc Gas sales-gas pipeline network are as follows:

  • Habshan gas compressor plant
  • Thammama-C manifold
  • Maqta manifold
  • KM-42 station
  • Taweelah gas compressor plant

Additionally, Adnoc Gas will also acquire its parent Adnoc Group’s 60% share in the Ruwais LNG terminal project at cost in the second half of 2028. UK energy producer BP, Japan’s Mitsui & Co, UK-based Shell and French energy producer TotalEnergies are the other shareholders in the project, holding 10% stakes each.

Adnoc Gas recently announced it is executing a capital expenditure (capex) budget of $28bn for 2026 to 2030, reaffirming the spending plan it previously committed to for the period.

As part of that capex plan, Adnoc Gas said it achieved final investment decision (FID) on the second and third phases of its Rich Gas Development (RGD) programme earlier this year.

The company awarded $8.2bn of EPC contracts for the second and third phases of the RGD programme. These relate to the construction of a new gas processing train at the Habshan complex and a natural gas liquids (NGL) fractionation train at the Ruwais gas processing facility, respectively.

Adnoc Gas detailed its capex plan as part of a media roundtable to discuss its financial results for the second quarter of the year (Q2 2026).

The company achieved net income of $665m in Q2 2026 – above the upper end of the $400m-$600m guidance range provided in the first quarter.

Supported by its cash flow from operations, the company’s board has approved a quarterly dividend of $940m, payable in September, in line with its commitment to deliver annual dividend growth of 5% through 2030.

  • Brent hits $112 a barrel following Saudi oil field attack

    22 October 2026

    Register for MEED’s 14-day trial access 

    Oil prices climbed more than 3% on 22 October after a drone targeting Saudi Aramco’s Shaybah oil field development killed two people and injured two others a day earlier, adding to concerns over energy supplies as attacks on Saudi energy infrastructure intensified.

    Global benchmark Brent crude hit $112.30 in early trading on 22 October, but later pared gains and was trading at $111.52 a barrel as of 11am GST.

    Three residents and a Saudi citizen were killed in two separate incidents in Saudi Arabia’s Eastern Province on 21 October, authorities said, as attacks on the kingdom accelerated following an escalation of hostilities with the Iran-backed Houthi group in neighbouring Yemen.

    Overnight, the Saudi-led coalition fighting the Houthis in Yemen announced that it had intercepted and destroyed four drones in the Eastern Province.

    Saudi air defences intercepted a drone attempting to target a processing facility at Saudi Aramco’s Shaybah oil field development on the morning of 21 October, the Saudi Ministry of Energy said.

    The official Saudi Press Agency (SPA) carried a statement quoting an energy ministry official as saying the attempted attack resulted in the deaths of two residents – a Filipino and a Nepali – and injuries to two others – an Indian and a Pakistani – after debris fell due to the interception.

    Following the interception, a fire broke out in a vehicle belonging to a contractor at the Shaybah oil field, outside the facility’s perimeter, with no impact on operations.

    Dammam airport attack

    Separately, a Houthi attack on King Fahd International airport in Dammam on the evening of 21 October killed an Indian resident and a Saudi citizen.

    Eight people were also injured in the attack, including a Saudi national, a Nepali, and two nationals each from India, Yemen and Bangladesh. Injuries ranged from minor to critical, the Saudi General Authority of Civil Aviation (Gaca) said the next day.

    “The attack also caused property damage, the extent of which is currently being assessed. Further updates will be provided,” Gaca said, adding that operations had since resumed at Dammam airport.

    Saudi Arabia has come under sustained attack from the Iran-aligned Houthi rebel group in October, including strikes on Riyadh’s international airport in what authorities described as the kingdom’s deadliest incidents in years, as the war with the group escalates.

    The Houthi militias also struck an administrative building at Aramco’s headquarters in Dhahran, in the Eastern Province, on 13 October, resulting in a limited fire.

    The Houthi rebels opened a new front in the regional war between Iran and the US in mid-July, when they breached a four-year truce with Saudi Arabia in Yemen’s civil war, which began in 2014, and started attacking Saudi vessels and Aramco energy assets along the Red Sea, including repeated strikes on the Jizan refinery.

    The 1,200-kilometre East-West pipeline operated by Aramco was also hit by Houthi missiles in September, and once directly by Iran in April.

    The East-West pipeline transports crude from Saudi Arabia’s Eastern Province oil fields to the Red Sea port city of Yanbu on the kingdom’s west coast. It has a pumping capacity of 7 million barrels a day.

    Saudi Arabia relies heavily on the East-West pipeline to bypass the volatile Strait of Hormuz maritime chokepoint and ship crude from its Red Sea coast. Riyadh has increasingly used the line to route exports away from Hormuz since the US-Iran conflict began on 28 February – a tactical advantage most of its Gulf neighbours lack.

    Aramco resumed crude exports via the pipeline at the start of October.

  • Riyadh awards $301m Sheikh Jaber Road contract

    22 October 2026

     

    Register for MEED’s 14-day trial access 

    The Royal Commission for Riyadh City (RCRC) has awarded an estimated SR1.13bn ($301m) contract to local firm Alomaier Trading & Contracting Company to upgrade a section of Sheikh Jaber Al-Ahmad Al-Sabah Road in the capital.

    The project covers the construction of an urban road about 3 kilometres (km) long, with a right-of-way width of about 120 metres.

    The scope of work includes the delivery of three interchanges featuring post-tensioned, voided-slab concrete bridges; a cut-and-cover tunnel; and three box culverts designated IC02, IC03 and IC04.

    The contract also encompasses pumping and lifting stations, stormwater drainage and irrigation networks, earthworks, asphalt paving, roadway lighting, power distribution systems, mechanically stabilised earth retaining walls and landscaping works.

    The award forms part of RCRC’s wider programme to upgrade Riyadh’s arterial road network, decongest critical bottlenecks and expand transportation capacity in the city ahead of Expo 2030 and the 2034 Fifa World Cup.

    The contract award follows RCRC’s appointment in May of a joint venture of Riyadh-based Al-Rashid Trading & Contracting Company and Turkiye’s IC Ictas for an estimated SR5bn ($1.3bn) contract to construct another section of Sheikh Jaber Al-Sabah Road.

    That project covers 12km from Khurais Road to Al-Thumama Road and is a component of Riyadh’s Second Eastern Ring Road scheme.

    Alomaier Trading & Contracting Company has secured several contracts in recent months.

    In August, Saudi Arabian Railways awarded the contractor an estimated SR4bn-plus ($1.1bn) contract to add a second track to the first section of the existing phosphate railway in the kingdom’s Eastern Province.

    The railway package covers about 100km between AZ1/Nariyah Yard and Ras Al-Khair. Works include track doubling, alignment modifications, utility bridges, culvert widening, hydrological structures, conversion of the AZ1 siding into a mainline track, and enabling works for signalling and telecommunications systems.

  • Dewa International signs energy and infrastructure MoUs

    22 October 2026

    Dubai Electricity & Water Authority’s (Dewa) new development arm, Dewa International, has signed four memorandums of understanding (MoUs) with international partners to explore investment and project development opportunities in the energy, water and infrastructure sectors.

    The agreements, signed during Dubai’s Water, Energy, Technology and Environment Exhibition (Wetex 2026), follow the launch of the wholly owned subsidiary in June, as reported by MEED.

    At the time, the utility said the arm would be used to export Dubai’s energy and water infrastructure model, with a focus on developing conventional and clean energy projects for global markets.

    At Wetex, Dewa International signed an MoU with France’s EDF Power Solutions to explore potential joint participation in solar, wind, battery energy storage and pumped-storage hydropower projects.

    A separate agreement with China Energy International Group explores the company’s potential role as an engineering, procurement and construction (EPC) partner for major energy, water and infrastructure projects. The MoU also covers cooperation in project development and EPC services.

    A further agreement with UK-based Capital Dynamics focuses on potential joint investments in operational clean energy assets in Europe. The parties will also explore establishing an investment vehicle for future clean energy infrastructure investments.

    Dewa International also signed a fourth agreement with Mumbai-Headquartered Tata Consultancy Services, exploring the company’s potential role as a technical consultancy partner. The scope covers technology strategy, information technology and operational technology integration, and asset performance management solutions.

    Dewa currently has almost $7bn-worth of power and water projects under execution across the UAE, according to regional projects tracker MEED Projects.

    Its flagship Mohammed Bin Rashid Al-Maktoum Solar Park is the largest single-site solar park in the world. The utility is currently advancing the project’s seventh phase, with Abu Dhabi Future Energy Company (Masdar) recently submitting the lowest bid for the project, as exclusively reported by MEED.

  • QatarEnergy and TotalEnergies to develop Lebanon solar plant

    22 October 2026

    Register for MEED’s 14-day trial access 

    State-owned QatarEnergy and France’s TotalEnergies have agreed to jointly develop a solar power plant in Lebanon.

    The agreement was announced on 16 October during the Qatari prime minister’s official visit to Beirut, where he held a joint press conference with Lebanese Prime Minister Nawaf Salam.

    According to a statement published by the Lebanese Prime Minister's Office, the plant will be an initial project under a broader framework for energy cooperation between Qatar and Lebanon. Its capacity, location, investment value and implementation schedule have yet to be disclosed.

    Qatar’s Prime Minister Sheikh Mohammed Bin Abdulrahman Bin Jassim Al-Thani said: “The aim is to develop a major investment project that benefits the Lebanese economy, as well as the Qatari companies and entities participating in it.”

    Separately, Salam said the Lebanese and Qatari governments were “close to reaching an agreement” to rehabilitate, develop and modernise Lebanon’s electricity-generation infrastructure.

    The proposed project would cover the country’s various electricity-generation sources and associated infrastructure, aiming to improve the reliability of electricity supplies and reduce costs.

    The project would use a build, operate and transfer model, under which Qatari entities would finance, implement and operate the facilities without upfront investment costs for the Lebanese treasury, Salam said.

    Salam also said the proposal was being prepared with support from the International Finance Corporation, and that he hoped to present it to the Lebanese government soon.

    The wider initiative is intended to address Lebanon’s longstanding electricity-generation shortfall and overcome financing constraints that have delayed infrastructure projects in the sector.

    As MEED previously reported, the Lebanese government continues to advance broader reforms to the country’s electricity sector.

    In August, Lebanon’s Electricity Regulatory Authority invited private sector companies to submit expressions of interest (EoIs) for several upcoming power-generation projects.

    The EoIs cover up to five grid-connected solar photovoltaic projects with a combined installed capacity of 350 megawatts-peak. The projects are also expected to include battery energy storage systems with a combined capacity of 1,000 megawatt-hours. 

    The regulator is also seeking proposals for distributed dual-fired thermal power plants with net capacities of 20MW-100MW.
