Register for MEED's guest programme 

Adnoc Gas, the natural gas processing business of Abu Dhabi National Oil Company (Adnoc Group), has received interest from contractors in participating in a front-end engineering and design (feed) to engineering, procurement and construction (EPC) competition for a project to install a fifth natural gas liquids (NGL) fractionation train at its Ruwais gas processing facility in Abu Dhabi.

Adnoc Gas intends to add a fifth NGL fractionation train to its Ruwais complex, which will have an output capacity of 22,000 tonnes a day (t/d) or about 8 million tonnes a year.

Adnoc Gas issued the expression of interest (EoI) document for the Ruwais NGL Train 5 project on 28 February, according to sources. Contractors submitted their response to the EoI document by the deadline of 11 March.

The feed-to-EPC competition model involves the project operator selecting contractors to execute the feed work on the project. The operator will select the contractor with the most competitive feed proposal to execute EPC works on the project, while also compensating the other contestants for their work.

The Ruwais NGL Train 5 will consist of the following units:

  • NGL fractionation plant with a capacity of 22,000 t/d, including NGL fractionation facilities, downstream treatment units, sulphur recovery units, products storage, loading facilities and associated utilities, flares and interconnection pipelines with existing facilities
  • Two propane liquefied petroleum gas storage tanks and one paraffinic naphtha storage tank
  • Buildings – a central control building, outstations, substations and plant amenities
  • Electrical power connections. Power is to be sourced from the nearby Transco substation via a direct underground cable to the plot location

Adnoc Gas intends to issue the main tender for the project’s feed-to-EPC competition later in March. It plans to select contractors for the feed contest in May and expects to award the main contract in February next year.

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 from 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 across eight onshore and offshore sites, which include its Asab, Bab, Bu Hasa, Habshan and Ruwais plants.

The company also owns a 3,250-kilometre pipeline network across the UAE.

In December 2021, MEED reported that the erstwhile Adnoc Gas Processing had awarded Indian contractor Larsen & Toubro Hydrocarbon Engineering the main contract for a project to enhance the capacity of its NGL trains 1-4 at the Ruwais complex.

  • Consultants submit bids for Saudi Arabia’s GCC rail link

    20 July 2026

     

    Consultants submitted proposals on 14 July for a contract to provide design consultancy services for the Saudi Arabian section of the GCC railway network, which is intended to link all six member states.

    Saudi Arabia Railways (SAR) issued the tender on 7 May, MEED previously reported.

    The tender covers the concept, preliminary and issued for construction design stages. SAR requires the selected consultant to review, update and complete the existing preliminary design.

    The consultants who submitted bids include: 

    • Atkins with Khatib & Alami
    • DeutscheBahn with ARX
    • Egis with Sener
    • Idom with Dal al-Handasah
    • Systra

    Saudi Arabia’s section of the railway will start at Al-Khafji in the Eastern Province, near the border with Kuwait, and end at Al-Batha, on Saudi Arabia’s border with the UAE. The route length in Saudi Arabia will be about 672 kilometres (km).

    The railway will interface with the Kuwait National Rail Road (KNRR) project on the Kuwaiti side. Last year, MEED exclusively reported that the KNRR design contract was awarded to Turkiye’s Proyapi Muhendislik ve Musavirlik Anonim Sirketi.

    The KNRR forms part of the wider GCC rail network. GCC railway projects have gained renewed momentum since the six member states signed the Al-Ula Declaration in January 2021.

    In October last year, Qatar’s cabinet approved a draft agreement paving the way for a railway link between Qatar and Saudi Arabia as part of the GCC railway network.

    GCC railway line

    Under the overall plan, the railway will run from Kuwait, pass through Dammam in Saudi Arabia, reach Bahrain via a planned causeway, and continue from Dammam to Qatar, the UAE and, ultimately, Muscat via Sohar in Oman. The railway is reported to span about 2,186km in total.

    The route length within each member state is as follows: 684km in the UAE, 672km in Saudi Arabia, 306km in Oman, 283km in Qatar, 145km in Kuwait and 36km in Bahrain.

    The railway is designed for passenger trains travelling at 220km/h and freight trains operating at 80-120km/h.

    With high levels of project activity, governments in spending mode and renewed cooperation under the Al-Ula Declaration, the latest efforts to restart the GCC railway project may make more progress than previous attempts. If completed, the railway could prove transformational for a region that is globally connected but still divided by national borders.

  • Chinese firm wins Dubai drainage contract

    20 July 2026

    China State Construction Engineering Corporation (CSCEC) has announced it has won a contract to deliver a stormwater drainage pipeline package under Dubai Municipality’s Tasreef programme.

    The contract is for the TF-15-C2 stormwater drainage network project located along Umm Suqeim Road in the Al-Barsha and Al-Quoz areas of Dubai. 

    MEED exclusively revealed in May that the contractor had been selected for the engineering, procurement and construction (EPC) contract. The project is estimated to cost $162m.

    The scope of work includes the construction of about 20 kilometres of new stormwater pipelines, together with associated inspection and intake manholes. The project is located west of the Dubai Canal and will connect the Al-Quoz 3 and Al-Quoz 4 industrial areas with Al-Quoz 1.

    It is being delivered as part of Dubai’s Tasreef strategic plan, which supports the Dubai 2040 Urban Master Plan. Once completed, the new drainage infrastructure is expected to improve the emirate’s stormwater network, increase flood protection and enhance the resilience of Dubai’s infrastructure.

    In February, the municipality confirmed it had awarded contracts for five new projects under phase two of the programme to expand and strengthen Dubai’s stormwater drainage network.

    These include a separate contract awarded to CSCEC for the TF-11-C1 stormwater drainage project in the Dubailand area.

    Also in February, Dubai Municipality invited consultants to qualify for a contract to supervise construction on the TF-15-C2 stormwater drainage projects along with two other projects (TF-13-C1 and TF-16-C1) under the Tasreef programme.

    According to a source, a consultant has yet to be appointed.

    TF-16-C1 involves upgrading and rehabilitating the stormwater system east of the Dubai Canal, while TF-13-C1 involves building a water pipeline stormwater drainage system at Al-Marmoum, Al-Qudra and Al-Yalayis 2 & 3.

    Bids are currently under evaluation for the EPC contracts for both projects.

  • Firms given more time for Mid Island Parkway prequalifications

    20 July 2026

     

    Abu Dhabi’s Modon Infrastructure has extended the deadline to 31 July for firms to submit expressions of interest and prequalification statements for the next phase of Abu Dhabi’s Mid Island Parkway Project (MIPP), which will be developed as a public-private partnership (PPP).

    The previous deadline was 15 July. MEED understands the prequalification notice was issued in June, following Modon Infrastructure’s invitation in May for firms to register their interest.

    Modon Infrastructure will act as the lead developer and will hold a majority equity stake in the project company. It will award contracts for engineering, procurement and construction; operations and maintenance; and project advisory services.

    Phase two of the MIPP involves the construction of about 11 kilometres (km) of highways, comprising a mix of three-, four- and five-lane sections. The highways will connect the Um-Yifeenah, Al-Jubail, Al-Sammaliyyah and Sas Al-Nakhl islands to Khalifa City and the E10 road.

    The scope also includes the construction of three interchanges – E20, E10 and Dumbbell – on Al-Sammaliyyah Island.

    The project includes several major structures, including the E20 interchange, which will feature cast-in-place box-girder and void-slab bridges, and the E10 interchange, which will feature cast-in-place box-girder bridges. It also includes I-girder bridges between Raha Beach West and Sas Al-Nakhl Island, as well as a causeway at Sas Al-Nakhl Island.

    Further elements include a cast-in-place balanced cantilever bridge between Sas Al-Nakhl Island and Al-Sammaliyyah Island; a tunnel between Al-Sammaliyyah Island and Bilrimaid Island; and a cut-and-cover (open) tunnel on Bilrimaid Island. Another tunnel will connect Bilrimaid Island to Um-Yifeenah Island.

    Abu Dhabi awarded three packages for phase one of the MIPP in 2024. The contract for Package 1A was awarded to a joint venture of Turkish contractor Dogus Construction and UAE firm Gulf Contractors. Package 1B was awarded to a joint venture of Yas Projects (Alpha Dhabi Holding) and China Railway International Group. Beijing-headquartered China Harbour Engineering Company and the UAE’s Agility Engineering & Contracting Company won the contract for Package 1C.

    Phase one starts at the existing Saadiyat Interchange, connecting the E12 to the MIPP, and ends at the recently constructed Um-Yifeenah Highway.

    It comprises a dual main road with a total length of 8km, including four traffic lanes in each direction, two interchanges, a tunnel and associated infrastructure works.
