Firms express interest in new Hail and Ghasha phase
22 May 2023

Register for MEED's guest programme
Contractors have expressed interest in tendering for new engineering, procurement and construction (EPC) contracts for Abu Dhabi National Oil Company’s (Adnoc’s) multibillion-dollar Hail and Ghasha sour gas development.
Adnoc started a fresh EPC tendering round for the project on 29 April. Contractors were issued expression of interest (EoI) documents just days after the cancellation of the pre-construction services agreements (PCSAs) that had been awarded in January.
Firms were initially asked to express interest in the new EPC tendering round by 14 May. According to sources, the deadline was extended until 19 May and firms submitted EoIs by that date.
The new EoI document details Adnoc’s latest EPC execution strategy for the Hail and Ghasha development. Under these plans, the offshore and onshore scope of work has been divided into three packages:
- Package one: Subsea pipelines, umbilicals, cables, risers and other offshore structures
- Package two: Offshore drilling centre facilities, the Ghasha offshore processing plant and central living quarters
- Package three: The Manayif onshore processing plant, including offsite export pipelines and tie-ins, utilities, the main control building and process buildings. Work on a Ruwais sulphur-handling terminal and other non-process buildings is an optional scope for this package.
An Adnoc spokesperson previously told MEED: “Adnoc and our international partners remain committed to delivering the gas mandated from the Ghasha concession. We do not comment on market speculation.”
PCSAs cancelled
The PCSAs signed in January with two consortiums, comprising three contractors each, marked the start of detailed engineering work and procurement of critical long-lead items for the offshore and onshore scope of work on the Hail and Ghasha development.
A consortium of France-headquartered Technip Energies, South Korean contractor Samsung Engineering and Italy’s Tecnimont was awarded the PCSA for the onshore package. The contractors revealed the value of the contract to be approximately $80m.
Italian contractor Saipem, Abu Dhabi’s National Petroleum Construction Company (NPCC) and state-owned China Petroleum Engineering & Construction Company (CPECC) won the PCSA for the offshore package, worth $60m.
Previously, the onshore work on the Hail and Ghasha scheme involved the construction of a gas process plant, pipeline network and new gas gathering units.
The offshore PCSA covered installing offshore platforms, gas compression facilities and more than 400 kilometres of subsea pipelines.
The reason for these PCSAs being annulled is unclear, but sources previously said the cost estimates submitted for the project were higher than the client’s overall budget.
Protracted project timeline
The cancelled PCSAs were part of an early engagement process with contractors that Adnoc started following the termination of at least two earlier bidding rounds.
US engineering firm Bechtel completed the project’s original front-end engineering and design (feed) in 2019, with tenders for four EPC packages issued soon after.
Following the submission of commercial bids in early 2021, Adnoc made revisions to the feed as part of an optimisation process started by Technip Energies in November 2021. The revised feed aimed to reduce the scheme’s overall capital expenditure, which was previously estimated to be as high as $15bn.
The four original EPC packages were consolidated into two integrated offshore and onshore packages, thought to be worth as much as $5bn and $5.5bn, respectively, based on the previous version of the project.
MEED reported in September last year that early engagement contractors had submitted proposals for the detailed engineering work on the Hail and Ghasha development. The January PCSAs are understood to have been issued based on these proposals.
Hail and Ghasha fields
The Hail and Ghasha fields, along with the Hair Dalma, Satah, Bu Haseer, Nasr, Sarb, Shuwaihat and Mubarraz fields, are located in Abu Dhabi’s offshore Ghasha concession.
Adnoc holds the majority 55 per cent stake in the Ghasha concession. The other stakeholders are Italian energy major Eni with 25 per cent, Germany’s Wintershall Dea with 10 per cent and Austria’s OMV and Russia’s Lukoil, each with 5 per cent.
Adnoc plans to produce more than 1.5 billion cubic feet a day of sour gas from the Ghasha concession by the middle of this decade. This target is aligned with the company’s broader goal of achieving gas self-sufficiency for the UAE by 2030.
In November 2021, Adnoc and its partners in the Ghasha concession awarded two EPC contracts for the Dalma offshore sour gas development project. Abu Dhabi’s NPCC and Spain-headquartered Tecnicas Reunidas won contracts worth $1.46bn to execute offshore and onshore EPC works on the Dalma project, respectively.
Four artificial islands have already been completed in the Ghasha concession, and development drilling is under way.
In addition, Adnoc awarded two contracts totalling $2bn to its subsidiary Adnoc Drilling in July last year for the Hail and Ghasha offshore sour gas field development project.
The awards comprise a $1.3bn contract for integrated drilling services and fluids, and a $711m contract to provide four island drilling units. Their duration is 10 years.
Adnoc also awarded a third contract, valued at $681m, to another subsidiary, Adnoc Logistics & Services, to provide offshore logistics and marine support services for the planned Hail and Ghasha development.

Jeddah tenders stormwater drainage contracts27 August 2026
Jeddah Municipality has invited contractors to bid for a contract covering the construction of a rainwater drainage network for the Prince Fawaz neighbourhood.
The project aims to collect and convey rainwater away from residential streets and low-lying areas. It is valued at $60m and intended to reduce flooding risks during heavy rainfall.
The scope includes manholes, stormwater catch basins and connections to existing manholes as well as the restoration of road surfaces.
The bid submission deadline is 12 October.
The municipality is also progressing with a second stormwater drainage project for the first package of Zone (BC), Old Zahraa in Jeddah Governorate, with bids due on 2 September. The project is valued at about $30m.
The two projects are part of the muncipality's wider drainage programme including the flagship King Abdullah Road-Falasteen Road tunnel project,
MEED previously reported that Saudi contractor Thrustboring Construction Company had been selected for phases one and two of the project, each valued at about $175m, covering the construction of large-diameter stormwater drainage tunnels.
It is understood an official agreement has still yet to be signed.
In June, MEED reported that local contractor Alkhorayef Water & Power Technologies (AWPT) had signed two contracts with Jeddah Municipality to operate and maintain stormwater and surface water drainage networks across the city.
The contracts have a combined value of SR202.06m ($53.9m), and each will run for five years.
The first contract, valued at SR108.46m ($28.9m), covers the operation and cleaning of stormwater and surface water networks in the South and Al-Malisa sub-municipalities.

Saur and Nesma sign water infrastructure deal26 August 2026
French firm Saur and local contractor Nesma & Partners have signed a deal to jointly "pursue the design and construction" of two recycled water plants in Riyadh.
The memorandum of understanding (MoU) was signed during the French-Saudi Investment Roundtable Meeting in Paris on 24 August.
It builds on an earlier agreement by the companies last September focusing on developing desalination and sewage treatment plants aceross the kingdom including project development, engineering, procurement, construction (EPC) and long-term operations and maintenance (O&M).
At the time, the companies agreed to "target industrial water treatment through concession and operations contracts," extending the agreement beyond municipal water infrastructure.
The latest agreement appears to mark a move from the broader partnership towards specific project opportunies in the Riyadh market. Details of the projects were not disclosed.
In May, MEED exclusively reported that a consortium including Saur, Nesma and another local firm Al-Bawani was preparing to bid for the Riyadh East Independent Sewage Treatment Plant (ISTP) project, of which, the submission deadline was recently extended to 29 September.
There are almost $2.5bn worth of water treatment projects at the pre-execution stage in Saudi Arabia, according to regional tracker MEED Projects.
The French-Saudi Investment roundtable meeting was organised as part of Saudi Crown Prince and Prime Minister Mohammed Bin Salman’s state visit to France.
Saudi Aramco also announced agreements and a memorandum of understanding (MoU) with French companies, worth a potential combined value of more than $3.7bn.
Among the other agreements signed during the conference was a cooperation agreement between Saudi Energy and French public investment bank Bpifrance, valued at up to $3bn, to support financing for projects to develop and expand Saudi Arabia’s power grid.

Technip Energies secures role in Umm Shaif Gas Cap project26 August 2026
France-based Technip Energies has secured a contract to provide detailed engineering services on a key offshore package part of the Umm Shaif integrated gas cap and surface pressure boosting project of Adnoc Offshore.
The detailed engineering services deal was awarded as a sub-contract to Technip Energies by India’s Larsen & Toubro Energy Hydrocarbon (L&TEH), in its capacity as the main contractor on the package 1 of the Umm Shaif gas cap project.
MEED previously reported about the offshore business of Abu Dhabi National Oil Company (Adnoc Offshore) awarding the main EPC contract for package 1 to a consortium of L&TEH and Saudi Arabia/UAE-based Lamprell.
Both L&TEH and Lamprell have confirmed their respective contract awards.
Under the detailed engineering contract, Technip Energies, in its statement on 26 August, said it “will draw on its strong local engineering capabilities and extensive experience with complex, large-scale offshore projects in the Middle East.”
In July, Adnoc and its foreign partners announced a $6.2bn final investment decision (FID) for their 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.
The Umm Shaif Gas Cap reserve is located within the offshore Umm Shaif and Nasr hydrocarbons concession, which is operated by Adnoc as the majority stakeholder. The other stakeholders in the concession are Italy’s Eni, France’s TotalEnergies and China National Petroleum Corporation (CNPC).
Adnoc said the FID includes three EPC packages totalling $5.1bn for large-scale offshore infrastructure, awarded to consortiums comprising major UAE and international contractors. The company did not disclose the contractors or the scope of work.
MEED reported in May that the following contractors had emerged as frontrunners for the two offshore packages and one onshore package of the Umm Shaif gas cap and surface pressure boosting project:
- 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)
McDermott recently confirmed its contract award for package 2, describing the order as “mega”, a term the company uses for jobs valued above $1bn.
In its 21 July statement, 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.
“The FID for Umm Shaif Gas Cap is the latest milestone in the company’s gas growth strategy and will unlock more than 600 million standard cubic feet per day of natural gas and associated gas liquids, equivalent to almost 10% of the UAE’s current daily gas consumption. The investment will reinforce the UAE’s energy security and its role as a reliable global energy supplier,” Adnoc said.
Production from the development is expected by 2030, the Abu Dhabi energy giant said.
“The UAE holds the seventh-largest gas reserves in the world. As global demand for reliable, lower-carbon energy continues to grow, Adnoc is unlocking more of the nation’s gas resources and expanding its liquefied natural gas (LNG) portfolio to meet the needs of its domestic and international customers and power industrial and artificial intelligence (AI) infrastructure growth,” it added.
Umm Shaif Gas Cap project
Adnoc Offshore, the offshore oil and gas business of Adnoc Group, is the operator of the Umm Shaif gas cap and surface pressure boosting project, MEED has reported.
The primary objective 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 2 February deadline.
The following contractors are among those understood to be 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.
Umm Shaif gas production
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 in 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 Eni, 20% to TotalEnergies and 10% to 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.
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.

Wabag confirms $372m Kuwait desalination contract26 August 2026
India's VA Tech Wabag has confirmed it has signed a contract to supply, install, operate and maintain the second phase of the Doha seawater reverse osmosis (SWRO) desalination plant.
Wabag confirmed the signing in a Regulation 30 filing on 25 August to the National Stock Exchange of India and BSE Limited.
The contract is valued at KD114.28m ($372m) and will be delivered by a Wabag-led unincorporated joint venture with Kuwait’s Heavy Engineering Industries & Shipbuilding Company (Heisco).
In April, MEED reported that Kuwait’s Central Agency for Public Tenders had approved the recommendation of the Ministry of Electricity & Water to award the contract to the joint venture.
It is understood that the decision then had to go through final approval from the Audit Bureau
The project will deliver a production capacity of about 60 million imperial gallons a day (MIGD) equivalent to about 272 million litres a day.
It will include the desalination plant with full reverse osmosis trains, pre- and post-treatment systems, recarbonation equipment, booster pumps, and safety and filtration systems. On-site solar photovoltaic systems will also provide part of the plant’s energy requirements.
According to the filing, construction is scheduled to take 36 months, followed by a five-year operation and maintenance period.
The Doha SWRO desalination plant is part of Kuwait’s broader programme to expand water production capacity and reduce reliance on thermal desalination methods.
As reported by MEED, the Heisco/Wabag joint venture submitted the lowest of three bids for the project in August 2025.
In April 2025, MEED reported that Kuwait had retendered the contract for the facility after the ministry cancelled the initial tender in June 2024.
The Ministry of Electricity & Water awarded South Korea’s Doosan Heavy Industries & Construction – now known as Doosan Enerbility – a $422m contract in May 2016 to build the 60 MIGD Doha 1 SWRO plant.
The contract marks Wabag's first project in Kuwait. In June, the contractor also won its first major contract in the UAE for the Ajman sewage biorefinery plant phase 3 project.

Key approval given for $381m Kuwait oil project26 August 2026
The Supreme Purchasing Committee for Kuwait Petroleum Corporation (KPC) has approved the award of an oil project contract worth KD117m ($381m) for India’s Megha Engineering & Infrastructure (Meil), according to industry sources.
The approval was granted earlier this month and has paved the way for an official contract award, sources said.
The scope of the project is focused on a water separation facility at the Al-Rawdatain facility in Kuwait.
The water separation facility is being developed at Gathering Centre 25 (GC-25) and a pumping facility is being developed at GC-30.
Six companies submitted bids for the project in November last year.
The full list of bids was:
- Meil (India) – KD117m ($381m)
- Mechanical Engineering & Contracting Company (Kuwait) – KD130m
- Spetco (Kuwait) – KD158m
- Al-Kharafi (Kuwait) – KD164m
- China Oil HBP Science & Technology (China) – KD169m
- Alghanim International (Kuwait) – KD169m
- Jereh Oil & Gas Engineering (China) – KD191m
The client on the project is state-owned upstream operator Kuwait Oil Company (KOC).
The project will deliver a wide-ranging upgrade of processing and utility infrastructure, including new low-pressure separation and gas handling equipment such as a three-phase wet separator package, a gas knock-out drum and associated LP gas pipelines, alongside a high-integrity pressure protection system and a high-pressure flare.
In October last year, KOC awarded Meil a separate contract for a project to develop a gas sweetening and recovery facility in West Kuwait.
Meil submitted the lowest bid for that tender, at KD69.2m ($225.5m), in February 2025.
