Offshore oil and gas sees steady capex
6 March 2025

This package also includes: Saudi Arabia to retain upstream dominance
With nearly half of the Middle East and North Africa’s (Mena) hydrocarbons reserves located in offshore basins, regional oil and gas producers spend significantly on maintaining and ramping up production levels. Offshore projects are predominantly geared at raising drilling capabilities, expanding subsea infrastructure and building floating production systems.
In addition to boosting production capacity, producers also invest in offshore projects to improve technological innovation, safety and environmental sustainability.
Capital expenditure (capex) on offshore projects in the region has remained steady in the past 10 years, with 2024 being one of the best years on record, witnessing total project spending of $23.5bn.
Qatar’s offshore goals
Qatar accounted for the largest capex on offshore oil and gas projects in Mena last year, according to data from regional projects tracker MEED Projects. The country invested more than $12bn in projects to produce incremental volumes of gas from its North Field reserve, as well to sustain its crude output.
In January 2024, North Oil Company awarded $6bn-worth of engineering, procurement and construction (EPC) contracts for a third capacity expansion project at the Al-Shaheen offshore field, to boost oil production by about 100,000 barrels a day (b/d).
North Oil Company – a joint venture of state enterprise QatarEnergy (70%) and France’s TotalEnergies (30%) – has been operating the Al-Shaheen field since July 2017. Situated 80 kilometres (km) north of Ras Laffan, at a water depth of 60 metres, Al-Shaheen holds one of the biggest oil reserves in the world and is Qatar’s largest field. It has a production potential of 300,000 b/d and accounts for about 45% of the country’s total oil production.
Meanwhile, Qatar’s North Field liquefied natural gas (LNG) expansion requires state enterprise QatarEnergy to pump large volumes of gas from the North Field offshore reserve to feed the three phases of the $30bn-plus programme. QatarEnergy has invested billions of dollars in EPC works on the two phases of the North Field Production Sustainability (NFPS) project, which aims to maintain steady gas feedstock for the North Field LNG expansion phases.
QatarEnergy LNG, a subsidiary of QatarEnergy, awarded Italy’s Saipem an order valued at $4bn for combined packages Comp3A and Comp3B of the NFPS Offshore Compression Programme’s second phase in September last year. The scope of work on the packages encompasses the engineering, procurement, construction and installation (EPCI) of six platforms, approximately 100km of 28-inch- and 24-inch-diameter corrosion-resistant alloy rigid subsea pipelines, 100km of subsea composite cables, 150km of fibre optic cables and several other subsea units.
The job for combined packages Comp3A and Comp3B is Saipem’s latest contract award as part of the NFPS scheme. The Italian contractor has secured work totalling almost $6bn on the two phases of the project.
UAE pushes offshore
With Abu Dhabi National Oil Company (Adnoc Group) striving to attain an oil production capacity of 5 million b/d by 2027 and become self-sufficient in gas production by the end of this decade, offshore oil and gas projects have received a significant boost. Adnoc was the second-highest spender on offshore projects in the region last year, as well as in the past 10 years.
In 2024, Adnoc Group subsidiary Adnoc Offshore spent about $6bn on major programmes to potentially increase oil production, such as the two phases of a project to raise output from the Upper Zakum offshore concession in Abu Dhabi to 1.2 million b/d.
In April last year, Adnoc Offshore awarded the project’s main EPC contract – known as UZ 1.2MMBD EPC-1 and worth $825m – to UAE-based Target Engineering Construction Company. In November, Target also won the contract for the project’s next phase, known as UZ 1.2MMBD EPC-2, which is understood to be valued at $500m.
Also last year, Adnoc Offshore awarded a contract, estimated to be worth $2bn, for a project to increase production from the Umm Shaif offshore oil field in Abu Dhabi.
US-based oil and gas contractor McDermott International won the main contract for the Umm Shaif Accelerated Development project, which aims to increase the Umm Shaif oil field’s output from about 275,000 b/d to 390,000 b/d by 2027, and to sustain that level of production until at least 2036.
Aramco maintains capex
In January 2024, the Saudi Energy Ministry directed Saudi Aramco to abandon its campaign to expand its oil production spare capacity from 12 million b/d to 13 million b/d by 2027. As a consequence of that government decision, Aramco cancelled the tendering process for at least 15 schemes involving the EPCI of structures at offshore oil and gas fields.
Aramco has since changed tack, spending an estimated $5bn in 2024 on offshore EPCI contracts and earning third place in the league table of highest offshore spenders in the Mena region last year.
Saipem was the biggest beneficiary of Aramco’s offshore spending, winning five of the eight Contracts Release and Purchase Orders (CRPOs) awarded last year.
In May, Aramco awarded Saipem the contract for CRPO 143, which involves replacing an oil line between the Berri and Manifa oil fields in the kingdom’s Gulf waters.
Aramco then awarded Saipem the contract for CRPO 138, which involves laying a trunkline at the Abu Safah offshore field. The contract is estimated to be worth $500m.
The Milan-listed contractor then scooped three CRPOs in August, starting with CRPOs 132 and 139, the combined value of which is estimated to be about $1bn. In September, Saipem began work on the two contracts, which involve the EPCI of structures to upgrade the Marjan, Zuluf and Safaniya offshore field developments.
Just days after the award of CRPOs 132 and 139, Aramco awarded Saipem CRPO 127, a $2bn contract that involves the EPCI of topsides and jackets for wellhead platforms, a tie-in platform jacket and topside, rigid flowlines, submarine composite cables and fibre optic cables at the Marjan oil and gas field.
In late November, Aramco awarded three further CRPOs worth more than $500m. China Offshore Oil Engineering Company won CRPOs 149 and 152, which are estimated to be valued at $30m and $250m-$300m, respectively. UK-based Subsea7 secured CRPO 153, which is understood to be valued at $200m-$250m.
Positive outlook
Regional national oil companies, particularly those in the Gulf, will seek to maintain a steady stream of investment in offshore projects this year, capitalising on the favourable oil price environment in pursuit of their goal of ramping up output potential in the mid to long term.
Their international counterparts are also likely to press ahead with projects to derive maximum value out of their offshore hydrocarbons assets in the Mena region, a large portion of which are located in prolific, shallow-water formations, making the production of oil and gas more cost-effective than in other regions.
Capex on offshore oil and gas projects this year may well match the level seen in 2024, according to MEED Projects data. In the first two months of 2025, offshore EPC contract awards reached $7.5bn.
Adnoc Offshore accounts for that entire spend through its Lower Zakum Long-Term Development Plan (LTDP-1) project. The company’s long-term objective is to raise output capacity at the Lower Zakum offshore hydrocarbons concession in Abu Dhabi to 520,000 b/d by 2027 and maintain that level until 2034.
Spanish contractor Tecnicas Reunidas and Abu Dhabi-based contractors NMDC Energy and Target Engineering Construction Company have been selceted by Adnoc Offshore to execute EPC works on the three main packages of the Lower Zakum LTDP-1 project.
Separately, Aramco is in the bid evaluation and tendering stages with a total of 12 more CRPOs. The biggest of these offshore tenders are a set of four CRPOs – numbers 145, 146, 147 and 148 – that are part of a project to further expand the Zuluf offshore field development.
These four CRPOs, estimated to be worth about $5.8bn, involve the EPCI of several structures at the Zuluf field, to maintain and raise its long-term oil and gas production potential.
In addition to CRPOs 145, 146, 147 and 148, entities in Saudi Aramco’s Long-Term Agreement (LTA) pool of offshore contractors submitted bids last year for CRPO 150 – an estimated $50m tender that involves the installation of structures at Aramco’s Northern Area Oil Operations.
In December, Aramco issued seven more CRPOs – 154, 155, 156, 157, 158, 159 and 160 – for which its LTA contractors are in the process of preparing bids. Work on these tenders relates to EPCI on structures at several offshore oil and gas fields in Saudi Arabia.
Aramco has been the biggest spender on offshore oil and gas projects in the region in the past 10 years, with capex exceeding $48.5bn. The world’s largest company is predicted to spend significantly on offshore EPC projects in 2025, too.

Adnoc steps up crude expansion15 October 2026

Abu Dhabi National Oil Company (Adnoc Group) is entering a new phase of upstream investment as the UAE’s withdrawal from Opec opens the way for greater oil production flexibility. After spending an estimated $37bn on upstream projects in 2023 and 2024, the state-owned energy company continues to invest heavily in expanding crude production capacity and developing domestic gas supplies.
The investment programme supports two key targets: raising crude production capacity to 5 million barrels a day (b/d) by 2027 and achieving gas self-sufficiency by the end of the decade.
Following the UAE’s withdrawal from Opec in May 2026, Adnoc Group has nearly matched its 2024 upstream project spending level so far this year and is on course to surpass it by a significant margin.
The UAE had invested billions of dollars in expanding crude production capacity, but output quotas under the Opec+ framework had constrained its ability to translate that capacity into higher production and additional oil revenues in a high-price environment.
The UAE’s exit from Opec gives Adnoc greater flexibility to utilise its spare capacity, accelerate progress towards its 5 million b/d target and potentially exceed it. The company is positioning itself to capitalise on rising oil demand while retaining the flexibility to respond to market conditions.
Robust offshore spending
So far this year, Adnoc Offshore has awarded major contracts for projects involving the Satah Al-Razboot (Sarb) deep gas development, the expansion of the Nasr oil field and an increase in the Upper Zakum oil field’s output capacity to 1.5 million b/d.
Adnoc reached a final investment decision (FID) on the Sarb project in January and awarded the main engineering, procurement and construction (EPC) contract to US-based McDermott International. The contract is estimated to be worth around $500m, sources told MEED.
The project is expected to deliver 200 million cubic feet a day (cf/d) of gas by the end of the decade – enough to power more than 300,000 homes.
The scope includes the EPC of an offshore wellhead tower with four gas production wells, which will be connected to Das Island for processing through Adnoc Gas facilities. The works also include the installation of pipelines and intra-field connections linking the Sarb field to Das Island.
Also in January, Adnoc Offshore awarded McDermott a $942m contract for the Nasr-115 project, which will increase production capacity at the Nasr offshore field to 115,000 b/d. The field is located about 130 kilometres northwest of Abu Dhabi.
McDermott’s scope covers engineering, procurement, construction and installation services for two topside structures, a new manifold tower, a jacket, a bridge, associated pipelines, subsea cables and brownfield modifications.
UZ 1.5MMBD project
Located 84km offshore Abu Dhabi, Upper Zakum is the world’s second-largest offshore oil field and fourth-largest oil field overall. The UZ 1.5MMBD project is Adnoc Offshore’s latest crude production expansion scheme at the Upper Zakum field.
The project scope is divided into three packages. The first EPC package covers surface facilities required on the field’s existing artificial islands, including integrated gas-lift compressors, produced-water reinjection units, water treatment plants, pre-assembled manifolds and related facilities.
The second package covers offshore facilities and comprises several segments of subsea pipelines and subsea cables.
The third package covers work on Adnoc’s existing Zirku Island and will require additional oil tanks, a water treatment unit, an export gas compressor, a condensate treatment unit, and associated power and utilities facilities.
Adnoc Offshore awarded the first and third EPC packages of the UZ 1.5MMBD project to Spanish contractor Tecnicas Reunidas, while Abu Dhabi-based NMDC Energy won the second package. The overall scheme is estimated to be worth more than $10bn.
Umm Shaif Gas Cap
Gas production has also been a key capex area this year, with Adnoc and its foreign partners reaching a $6.2bn FID in July for a major project to produce up to 600 million cf/d of natural gas by developing the Umm Shaif Gas Cap in Abu Dhabi.
The Umm Shaif Gas Cap reserve lies within the offshore Umm Shaif and Nasr hydrocarbons concession, in which Adnoc is the majority stakeholder. Other stakeholders in the concession are Italy’s Eni, France’s TotalEnergies and China National Petroleum Corporation.
Adnoc said the FID includes three EPC packages totalling $5.1bn for large-scale offshore infrastructure, awarded to the following contractors:
- 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)
As part of the FID, Adnoc 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.
Separate from the Umm Shaif Gas Cap development, Adnoc Offshore is preparing to issue the main tender for the next expansion phase of the Umm Shaif oil and gas field offshore Abu Dhabi.
Contractors expressed interest to Adnoc Offshore in June in participating in the main tendering exercise for the Umm Shaif long-term development plan 2.1 (LTDP-2.1) project.
The project’s primary objective is to maintain Umm Shaif’s oil production capacity at approximately 390,000 b/d, while enabling peak output of up to 430,000 b/d.
The project includes constructing a new combined artificial island at Umm Shaif, equipped with drilling, processing, utilities and supporting infrastructure. It also includes installation of an optimised crude-stabilisation train at Adnoc’s existing Das Island facilities.
Located about 150km northwest of Abu Dhabi city, Umm Shaif is one of Adnoc’s oldest offshore oil-producing assets. In 2022, the company marked the 60th anniversary of the UAE’s first export of Umm Shaif crude, which took place in July 1962.

Joint venture wins Oman desalination contract15 October 2026
Bahwan Veolia Water, a joint venture of France’s Veolia and Oman’s Bahwan Engineering Company, has signed a five-year operations and maintenance (O&M) contract for the Al-Asilah desalination plant in the sultanate.
The Al-Asilah plant has a production capacity of 80,000 cubic metres a day and helps supply drinking water to about 600,000 residents across South Al-Sharqiyah governorate. It also has an on-site solar farm to support lower-carbon water production.
The plant entered commercial operation in January 2022 under a build-own-operate arrangement. A consortium of Bahwan Engineering and Japan-headquartered JGC Corporation developed it.
South Korea’s Doosan Heavy Industries & Construction, now known as Doosan Enerbility, carried out the engineering, procurement and construction (EPC) works.
Oman’s first independent water project (IWP), the Sur IWP, also serves residents in Al-Sharqiyah governorate.
The main contract for the project was awarded in 2007, with Veolia carrying out EPC works and acting as shareholder in Sharqiyah Desalination Company, which owns the plant.
Bahwan Veolia Water signed a 22-year O&M agreement for the project that same year.

Adnoc funnels billions into boosting gas processing15 October 2026

Abu Dhabi National Oil Company (Adnoc Group) is accelerating investment in gas processing and associated downstream infrastructure as demand in the UAE rises and the government prioritises lower-carbon energy growth.
Rising gas consumption in the UAE is being driven by rapid population growth, greater household electrification, expanding industrial bases and demand from gas-intensive downstream segments such as petrochemicals, fertilisers and metals.
Power generation and water desalination are also key sources of demand, while new industrial zones – as well as data centres supporting the expansion of artificial intelligence (AI) use in the country – add further baseload requirements.
Adnoc Gas, Adnoc Group’s gas processing subsidiary, is leading the UAE’s push to expand gas processing capacity and is executing a major capital expenditure (capex) programme worth $28bn over 2026-30.
As part of that capex plan, Adnoc Gas achieved a final investment decision (FID) on the second and third phases of its Rich Gas Development (RGD) programme earlier this year.
Adnoc Gas awarded $8.2bn of engineering, procurement and construction (EPC) contracts for the second and third phases of the RGD programme. These cover a new gas processing train at the Habshan complex and a natural gas liquids fractionation train at the Ruwais gas processing facility, respectively.
Under the awards, China-based Wison Engineering will execute phase 2 under a $3.9bn contract, while Italy’s Tecnimont has secured the $4.3bn phase 3 contract.
Adnoc Gas has also reiterated its $5bn capex for the first phase of the RGD scheme, which is under construction. The company awarded $5bn of engineering, procurement and construction management contracts in three tranches for phase 1 of the RGD programme in June last year, marking the company’s largest-ever capital investment.
Across all three phases, Adnoc Gas has committed a total of $13.2bn to the RGD programme.
Bab Gas Cap development
Looking ahead, Adnoc Gas is advancing towards FID on the estimated $8bn Bab gas cap development. The project will process up to 1.85 billion cubic feet a day (cf/d) of raw feed gas once Adnoc Group begins extracting reserves from four underdeveloped onshore reservoirs at the Bab field: Thammama A, B and H (projected to yield a combined 1.45 billion cf/d) and Thammama F (projected at 396 million cf/d).
Because existing trains at the Habshan complex cannot accommodate these supplementary volumes, the project entails building a processing plant approximately 170 kilometres from Abu Dhabi city, alongside pipeline networks and ancillary units.
Adnoc Gas has split the EPC scope into four packages, with technical bids due on 16 November:
- Package 1: Main Bab gas cap processing plant
- Package 2: Early civil works
- Package 3: Pipeline network
- Package 4: Non-process facilities and associated infrastructure
Four contractor consortiums prequalified to bid for the main contracts:
- Larsen & Toubro Energy Hydrocarbon (India) / Samsung E&A (South Korea)
- Saipem (Italy) / NMDC Energy (UAE)
- Technip Energies (France) / JGC Corporation (Japan) / Sinopec (China)
- Tecnimont (Italy) / China Petroleum Engineering & Construction Corporation
Gas pipeline investments
Adnoc Group continues to invest in projects to enhance its gas transmission networks across the UAE, following its $3.5bn-plus capex on the Estidama programme earlier this decade to expand its sales-gas network in the country.
Adnoc Gas recently awarded the main contract for a project to build a new pipeline that will supply gas from the Habshan scraper launcher station at its Habshan gas compression complex in Abu Dhabi to the Al-Nouf customer receiving station, for delivery to Emirates Water & Electricity Company (Ewec).
The proposed 56-inch, 127km pipeline will help the UAE’s state utility, Ewec, meet additional gas demand to power the second phase of an AI data centre in Abu Dhabi, as well as support the relocation of some of its key assets in the Mirfa area of the emirate.
Adnoc Gas awarded the EPC contract for the project to India-based Kalpataru Projects International.
Separately, Adnoc is moving ahead with plans to build an oil pipeline network that will transport crude from its main offshore oil processing islands in the Gulf to its onshore crude export terminal at Jebel Dhanna, Abu Dhabi.
The planned network will source crude from Zirku Island and Das Island, where Adnoc gathers and treats oil produced at Abu Dhabi’s offshore fields, among other processing hubs, and transport it about 300km inland to the Jebel Dhanna terminal.
The proposed pipelines will eventually connect to the West-East crude pipeline network currently being built from Jebel Dhanna to the emirate of Fujairah, which is expected to be commissioned in 2027.
Boosting chemicals output
Meanwhile, following major investments over the past three years to set up specialty chemical plants under the first phase of its chemical derivatives complex in Ruwais Industrial City, Taziz is firming up plans for the second phase of the complex.
Taziz has partnered with local conglomerate Alpha Dhabi to undertake a joint feasibility and market study and, subject to FIDs and regulatory approvals, the second phase of the Taziz Industrial Chemicals Zone could produce up to 14 new chemicals, with total output capacity of about 2.2 million tonnes a year (t/y).
The chemicals under study include styrene and polystyrene, acrylic acid and derivatives, polyols, methylene diphenyl diisocyanate (MDI), epoxy resins and linear alpha-olefins. These are widely used across construction, automotive, packaging, consumer goods, infrastructure and advanced manufacturing.
Taziz, Germany-based chemicals producer Covestro and XRG – all wholly or majority-owned subsidiaries of Adnoc Group – have launched a joint feasibility study to assess the development of a world-scale MDI plant in Ruwais Industrial City.
The partners aim to establish a facility in the Taziz Industrial Chemicals Zone with a production capacity of 660,000 t/y of MDI. The study will evaluate the technical, commercial and economic feasibility of the proposed plant, with the aim of informing a future investment decision.

Morocco extends deadline for El-Menzel pumped-storage plant15 October 2026
Morocco’s Office National de l’Electricite (One) has extended the deadline for contractors to submit bids for the 362MW El-Menzel pumped-storage hydropower project.
The new deadline is 25 November. Bids were previously due on 28 October.
The project is located about 35 kilometres southeast of Sefrou in the Fes-Meknes region. The engineering, procurement and construction contract covers engineering, equipment supply, construction, installation and commissioning.
The scope includes two reversible pump-turbine units, upper and lower reservoirs, underground water conduits, a 400kV substation and a transmission line connecting the facility to the national grid.
One tendered the project in July following an earlier prequalification process that began in May 2023, when six consortiums submitted applications.
Three consortiums were subsequently prequalified to bid for the main contract. These include:
- China International Water & Electric Corporation (China) / Yellow River Engineering Consulting Company (China) / Harbin Electric International Company (China) / Harbin Electric Machinery Company (China) / Jet Contractors (Morocco)
- Sinohydro (China) / Andritz Hydro (Austria)
- Webuild (Italy) / Dongfang Electric International Corporation (China)
The project aims to support Morocco’s renewable energy programme and help the country reach its target of sourcing 52% of its energy mix from renewables by 2030. It is being financed by the African Development Bank and Germany’s KfW Development Bank.
One already operates the 464MW Afourer and 350MW Abdelmoumen pumped-storage stations, while the 300MW Ifahsa project is under development.
In August, the Office National de l’Electricite et de l’Eau Potable (Onee) approved a MD248bn ($26.4bn) investment programme for 2026-30. The spending plan covers electricity and drinking water infrastructure.
The programme allocates $21.9bn to electricity projects and $4.5bn to drinking water infrastructure. According to Onee, the private sector will finance about 72% of the investment.
The electricity programme includes $11.1bn of investment to develop 11.6GW of renewable energy capacity and 2.6GW of energy storage. It also provides for 2,230MWh of battery energy storage systems, the El-Menzel pumped-storage hydropower plant and 3,744MW of gas-fired generation to support grid flexibility.

Contractors given extension on Riyadh airport aviation complex15 October 2026

Contractors have been given an extension until 19 November to submit proposals for an estimated SR3bn ($817m) contract to build an aviation complex within the King Salman International airport master development in Riyadh.
Government-owned aviation organisation Saudi Royal Aviation (SRA) tendered the contract in August, with an initial bid submission deadline of 8 October.
Phase one of the programme comprised the concept design stage, which the design consultant has completed.
SRA is now seeking to deliver the second phase, which covers design development, detailed design, procurement, construction, testing, commissioning and close-out of the works.
The scope covers 30 landside buildings, including 16 screening areas and gates, plus 15 airside buildings, including four gates.
The assets include maintenance hangars, workshops, office and administrative buildings (including interior fit-out), warehouses, storage, security and catering facilities, aprons and access roads, and site utilities and civil works.
King Salman International airport will provide primary utilities to designated tie-in points, with the contractor taking responsibility from there.
Although the site is within King Salman International airport’s boundaries, it is classified as landside and is a greenfield development. The contractor must therefore meet airport security, safety and access requirements, in addition to SRA’s own clearance processes.
Project scale
The King Salman International airport project covers an area of about 57 square kilometres (sq km), allowing for six parallel runways, and will include the existing terminals at King Khalid International airport. It will also include 12 sq km of airport support facilities, residential and recreational facilities, retail outlets and other logistics real estate.
The airport aims to accommodate up to 100 million passengers by 2030. The goal for cargo is to process 2 million tonnes a year by 2030.
Saudi Arabia plans to invest significantly in its aviation sector. The Saudi Aviation Strategy, announced by the General Authority of Civil Aviation, aims to triple Saudi Arabia’s annual passenger traffic to 330 million travellers by 2030.
It also aims to increase air cargo traffic to 4.5 million tonnes and raise the country’s total air connections to more than 250 destinations.
