Indian contractor Larsen & Toubro (L&T) has announced that it has been awarded a major contract by the offshore business of Abu Dhabi National Oil Company (Adnoc Offshore).
Mumbai-headquartered L&T described the order as “ultra-mega”, a term the company uses for contracts valued at more than INR150bn ($1.57bn).
The project will be executed through a consortium, with its subsidiary LTEH Offshore serving as the lead partner, L&T said in a statement on 4 August.
MEED understands that the contract won by L&T relates to an offshore package that forms part of a major Adnoc Offshore project to produce up to 600 million cubic feet a day (cf/d) of natural gas by developing the Umm Shaif gas cap in Abu Dhabi.
L&T won the first offshore package of the Umm Shaif gas cap and surface pressure boosting project in a consortium with Saudi Arabia/UAE-based Lamprell, MEED reported in July.
The following contractors have secured the two offshore packages and one onshore package of the Umm Shaif gas cap project, MEED previously reported:
- First offshore package – fabrication of a 30,000-tonne gas compression system: Larsen & Toubro Energy Hydrocarbon (India) / Lamprell (Saudi Arabia/UAE)
- Second offshore package – fabrication of another 30,000-tonne gas compression system: McDermott (US)
- Onshore package – EPC of gas inlet and processing systems on Das Island: China Petroleum Engineering & Construction Company (CPECC)
“The project involves the development of multiple offshore facilities. As the lead consortium partner, LTEH Offshore will execute the major share of the project scope, covering engineering, procurement, construction, installation and commissioning (EPCIC) of the offshore facilities, in addition to the upgrade of existing facilities,” L&T said in its statement.
“A significant portion of the fabrication work will be undertaken at L&T’s state-of-the-art fabrication yards, leveraging the company’s integrated EPCIC capabilities and extensive track record in delivering large and complex offshore developments across the region,” the Bombay Stock Exchange-listed company added.
Umm Shaif gas cap project
Adnoc Offshore operates the Umm Shaif hydrocarbons development, which is located 150 kilometres (km) northwest of the city of Abu Dhabi. The field is located within Abu Dhabi’s offshore Umm Shaif and Nasr hydrocarbons concession, previously operated by former Adnoc Group companies Adma-Opco and Zadco.
In March and April 2018, Abu Dhabi’s Supreme Council for Financial and Economic Affairs (SCFEA) awarded a 10% stake in the Umm Shaif and Nasr offshore block to Italy’s Eni, 20% to France’s TotalEnergies and 10% to China National Petroleum Corporation (CNPC). Adnoc Group retained the majority 60% interest. The operators produce a total of about 460,000 b/d of oil from the Umm Shaif and Nasr block.
Adnoc, along with its foreign partners, announced achieving a final investment decision (FID) worth $6.2bn on the Umm Shaif gas cap project on 21 July. The FID includes three EPC packages totalling $5.1bn for large-scale offshore infrastructure, “awarded to consortiums comprising major UAE and international contractors,” the state enterprise said without disclosing the contractors it had selected or the scope of work on the packages.
Adnoc added that, as part of the FID, it has also awarded a $365m contract to its subsidiary Adnoc Drilling for a 14-well drilling and integrated drilling services scope, to be delivered over 18 months using three existing rigs.
Production from the development is expected by 2030, the Abu Dhabi energy giant said.
The primary objective of the Umm Shaif gas cap and surface pressure boosting project is to increase gas production by 550 million cubic feet a day (cf/d) and raise associated condensate output by 50,000 barrels a day (b/d).
Adnoc Offshore intends to feed about 520 million cf/d of the additional produced gas into Adnoc Group’s sales gas grid.
Adnoc Offshore is understood to have issued the main EPC tender for the Umm Shaif gas cap and surface pressure boosting project in the first quarter of 2025.
Contractors submitted technical bids for the three EPC packages by the 30 October deadline last year, while commercial bids were submitted by the deadline of 2 February this year.
The following contractors are among those understood to have been bidding for the three EPC packages, according to sources:
Offshore package 1:
- Saipem (Italy) / Seatrium (Singapore)
- Larsen & Toubro Energy Hydrocarbon (India) / Lamprell (Saudi Arabia/UAE)
- NMDC Energy (UAE) / Hyundai Heavy Industries (South Korea)
Offshore package 2:
- China Offshore Oil Engineering Company (COOEC)
- McDermott (US)
- Larsen & Toubro Energy Hydrocarbon (India) / Lamprell (Saudi Arabia/UAE)
- NMDC Energy (UAE) / Hyundai Heavy Industries (South Korea)
Onshore package:
- Archirodon (Greece)
- China Petroleum Engineering & Construction Company (CPECC)
- Engineering for the Petroleum & Process Industries (Enppi; Egypt)
- Galfar Emirates (UAE branch of Oman’s Galfar Engineering & Construction)
- Target Engineering Construction Company (UAE)
Australian firm Worley has performed front-end engineering and design (feed) work on the project.
Gas is produced from the Umm Shaif Khuff and Uweinat reservoirs, as well as from the Arab C and Arab D Early Production Scheme 2. The Umm Shaif Khuff reservoir is a formation that consists of dry gas volumetric reservoirs located in the Umm Shaif field.
Khuff reservoirs have been in production in Abu Dhabi since August 1989. Umm Shaif Khuff gas is currently produced from 28 active wells within the Umm Shaif field. A majority of these wells supply gas to Adnoc Group subsidiaries Adnoc LNG and Adnoc Gas Processing, with the rest supporting oil reservoirs at the Umm Shaif field through gas injection.
The Umm Shaif Super Complex (USSC) processes and transports oil, condensates and natural gas in separate pipelines to Das Island for further processing and export. The condensates collected from the USSC are transported to Das Island through an 18-inch pipeline stretching 34.4km, or are spiked into the 36-inch Adnoc main oil line.
The gas collected from the USSC is transported to Das Island through two 46-inch pipelines, which also run 34.4km.
Pressure at the Umm Shaif Khuff gas reservoirs will start to decline by the end of 2028. The flowing wellhead pressures at some of the Khuff gas wellhead towers are likely to reduce, so boosting well deliverability and increasing the flowrates is necessary.
Therefore, new Khuff surface pressure boosting facilities are required to maintain the plateau – with a goal of achieving a 90% gas recovery factor – and increase production beyond the end of the plateau by lowering pressure at the Khuff reservoirs.

SAR tenders design review consultancy for GCC rail link18 September 2026

Register for MEED’s 14-day trial access
Saudi Arabia Railways (SAR) has issued a request for proposals (RFP) for a design management and review consultant to oversee engineering works on the GCC railway network, the latest step in advancing the long-delayed regional rail link.
The RFP was issued on 9 September, with a submission deadline of 18 October.
The tender seeks a consultant to manage, audit and verify deliverables produced by SAR's separately appointed design services consultant, rather than carry out the design itself. The tendering for the design services consultancy is currently in progress.
Construction will be tendered separately through competitive bidding once designs are approved.
The GCC railway will run for about 672 kilometres (km) inside Saudi Arabia, linking the kingdom's existing network to Kuwait, Qatar, the UAE and Bahrain, with four sections of about 141km, 200km, 151km and 21km, respectively.
The line is planned as a single-track, non-electrified corridor for mixed freight and passenger traffic, with a maximum axle load of 32.4 tonnes and passing loops for bidirectional working.
The appointed consultant will develop a design management and review plan covering governance, interdisciplinary coordination and stage-gate approvals, and will issue formal review and audit reports against SAR's requirements and international standards.
The scope also covers stakeholder engagement, interface management and oversight of land acquisition activity tied to the design consultant's land acquisition plan.
Key design stages are expected to take about 16 months: four months for concept design, six for preliminary design and six for issued-for-construction design, each with four weeks of contingency.
SAR has asked bidders to mobilise a core team from day one. These must include a project director, engineering and design manager, stakeholder manager and lead document controller, all based at SAR's offices, with minimum experience thresholds ranging from three years for junior operators up to 25 years, including 15 in rail, for the project director role.
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 cover about 2,186km in total.
The route length within each member state is as follows:
- UAE – 684km
- Saudi Arabia – 672km
- Oman – 306km
- Qatar – 283km
- Kuwait – 145km
- Bahrain – 36km
The railway is designed for passenger trains travelling at 220 kilometres an hour (km/h) and freight trains operating at 80km/h–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.

Tender issued for Libyan gas project17 September 2026
An invitation to bid has been issued for a contract to conduct environmental assessments for the project to expand the Mellitah oil and gas complex in Libya.
The bid submission deadline is 2pm today (17 September) Libyan time.
The scope of the project includes provision of:
- An environmental baseline study (EBS)
- An environmental impact assessment (EIA)
- An environmental management plan (EMP)
The client is Mellitah Oil & Gas (MOG), which is a joint venture of Italy’s Eni and Libya’s National Oil Corporation (NOC).
MOG is based in Tripoli and operates both onshore and offshore oil and gas facilities.
The joint venture owns and operates six major oil and gas fields across the North African country.
According to the tender documents, the company that is awarded the contract will need to prepare environmental management measures in compliance with:
- Libyan environmental legislation
- Ministry of Environment requirements
- NOC environmental guidelines
- Applicable international environmental standards and best practices
The expansion of the Mellitah oil and gas complex is part of a project estimated to be worth $8bn.
The wider project is known as the Mellitah Complex Expansion & CO2 Management Integrated Development Project.
It has six main packages:
- Onshore package
- Offshore Structure A
- Offshore Structure E
- Subsea pipeline package
- Site preparation work
- Carbon capture and storage facility
Security issues and political instability have been a major problem for Libya’s oil and gas sector since the country’s civil war started in 2011.
Earlier this month, the Mellitah oil and gas complex was forced to shut down temporarily due to a protest over deteriorating public services.
The existing onshore complex includes housing, processing units, storage facilities and export facilities.
It also serves as the launch point for the Greenstream pipeline, which delivers Libyan gas directly to Italy.
The planned expansion of the complex will involve:
- Construction of a new fourth gas processing train
- Construction of a third condensate train
- Construction of a third natural gas liquids fractionation train
- Construction of a fourth sulphur recovery unit train
- Installation of a hydrogen sulphide enrichment unit
- Installation of a sulphur recovery unit
- Construction of other associated facilities
The Mellitah complex is located about 100 kilometres west of Tripoli and is a key energy facility in the west of the country.

Nakheel awards $218m Dubai Islands buildings deal17 September 2026
Register for MEED’s 14-day trial access
Dubai-based developer Nakheel, now part of Dubai Holding, has awarded a main construction contract worth more than AED800m ($218m) for phases one and three of Bay Grove Residences at Dubai Islands.
The contract was awarded to the local firm Metac General Contracting Company.
It covers the construction of 537 apartments, comprising one- to four-bedroom units, across seven residential buildings.
Phase one includes 296 units in four buildings, while phase three comprises 241 units across three buildings.
The works are scheduled for completion in late 2028.
Bay Grove Residences will ultimately comprise 1,154 homes across 15 buildings. Planning is under way for the remaining 617 homes in phases two and four, with further contract awards expected.
In August last year, Nakheel awarded a AED2.6bn ($708m) contract to Abu Dhabi-based Fibrex Contracting to build the Bay Villas project at Dubai Islands. The contract includes constructing 636 villas.
In April this year, another AED527m ($143m) contract was awarded to local firm Al-Nasr Contracting Company to construct the primary infrastructure and utilities works on Island B at the development.
The Dubai Islands development consists of five islands spanning 18.6 square kilometres. It features more than 59 kilometres (km) of waterfront and 20km of beaches, as well as parks, golf courses, promenades and cycling paths.
The offshore island project gained renewed momentum in 2022, when Nakheel unveiled a new masterplan and rebranded it as Dubai Islands.
The reclaimed islands were originally part of the Palm Deira project, which was partially completed before being put on hold in 2008.

Neom tenders Oxagon highway contract17 September 2026

Saudi Arabia’s Neom has tendered a design-and-build contract covering permanent upgrade works on Highway 55 in the kingdom’s Oxagon region.
The first phase of the project includes constructing 14 kilometres of road, with two lanes in each direction. It also covers one bridge and three interchanges.
The project duration is 22 months.
Contractors have been given until 21 September to submit their proposals.
Highway 55 connects the Red Sea coast with the mainland in northwestern Saudi Arabia. It is currently the only road providing north-south connectivity between Duba and the Neom region.
MEED exclusively reported in August 2025 that contractors had submitted responses to the expressions of interest notice that Neom had issued earlier that month.
The project is expected to support the movement of cargo vehicles from Duba Port to other parts of the country and the wider region.
Neom tested a pilot initiative last year by handling a shipment that travelled from Cairo via the Port of Safaga, across the Red Sea to the Port of Neom, and then inland to Erbil, Iraq.
In a statement, Neom said: “The shipment travelled through an intermodal corridor spanning over 900 kilometres, marking a significant milestone in the kingdom’s transformation into a regional and global logistics hub.”
The Port of Neom is located on the Red Sea near the Arar border, a key entry point into Iraq.
