The region’s most ambitious causeway projects

8 February 2023

 

The submission of feedback questionnaires and meetings with contractors for the planned second causeway connecting Saudi Arabia and Bahrain is the latest sign of potential progress on one of the region’s largest infrastructure projects.

Causeways have a chequered history in the region. The first causeway connecting Saudi Arabia and Bahrain was completed during the 1980s, and since then, it has had a transformative impact on the Bahraini economy. 

The project’s success has inspired other causeways. But while these schemes remain ambitions for many in the region, construction progress has been limited. The hope is that a successful second causeway linking Saudi Arabia and Bahrain will foster the delivery of other longstanding causeway plans.

These are the most ambitious causeway schemes that the region has planned:

 Second Saudi Arabia-Bahrain causeway

The second causeway between Saudi Arabia and Bahrain is the most likely to proceed. Planned by the King Fahd Causeway Authority, the $3.5bn project, which has been called the King Hamad Causeway project, is moving towards construction.

In 2021, senior government officials in Bahrain told MEED that the project was progressing towards tendering as financial studies had been completed.

The project was included in Bahrain’s $30bn Strategic Projects Plan that was announced later in 2021. As well as the causeway, the plan includes building new urban areas on five reclaimed islands to increase the country’s total land area by 60 per cent. It also comprises plans for a new airport.

The second causeway involves building a 25-kilometre road and rail crossing linking Saudi Arabia and Bahrain. It will follow the same alignment as the existing King Fahd Causeway.

It has been earmarked for delivery on a public-private partnership (PPP) basis. The King Fahd Causeway Authority appointed a consortium to provide transaction advisory services in late 2019.

The $8.9m consultancy agreement was signed with a consortium of Netherlands-headquartered KPMG, US-based Aecom and UK-based CMS. The team was tasked with working on developing the financing model, the required engineering specifications and design, as well as helping with the assessment and selection of the project’s developers.

Canada-based SNC Lavalin and UK-based consultancy firm PwC conducted the project due diligence study in 2017.

The existing King Fahd Causeway is operating at capacity. About 11.5 million cars cross the causeway every year, and the growth has been 6 per cent per annum over the past 10 years.

 Qatar-Bahrain causeway

There have also been suggestions that the proposed causeway bridging Bahrain and Qatar may be revived. In March 2022, Manama called for work to restart on the causeway joining the two countries.

“We in the Kingdom of Bahrain renew the call for the start of bilateral talks between the two sides in accordance with the mechanisms agreed upon in the Al-Ula statement,” said Bahrain’s undersecretary for land transportation and post in an official statement published by the official Bahrain News Agency.

The estimated $4bn Qatar-Bahrain causeway project was put on hold and the contracting consortium demobilised in 2010.

A joint venture of state-owned developer Qatari Diar Real Estate Investment Company and French contractor Vinci Construction Grand Projets led the consortium. The other consortium members were Germany’s Hochtief, Athens-based Consolidated Contractors Company (CCC), Dredging International from Belgium and the local Middle East Dredging Company (Medco).

The planned 40km bridge includes a four-lane motor crossing scheduled for completion in 2013 and two railway lines forming part of the GCC rail network.

The project also comprises 22km of bridges and viaducts, 18km of embankments and two 400-metre cable-stayed bridges. The causeway connects Ras Ashairij on the west coast of Qatar to Askar on the east coast of Bahrain.

The project was also known as the Friendship Bridge and was to be jointly funded by the Qatari and Bahraini governments, which intended to recover some of the construction costs by implementing a toll system on the bridge.

The crossing would cut the journey time between the two countries, which currently involves a detour through Saudi Arabia, from five hours to just 30 minutes.

 Saudi Arabia-Egypt causeway

The prospects for the causeway connecting the $500bn Neom project in Saudi Arabia and Egypt’s Sinai Peninsula across the Straits of Tiran improved last year after US President Joe Biden’s visit to Saudi Arabia.

After the visit, a joint communique issued by Washington and Riyadh referred to the development of Tiran Island.

“President Biden welcomed the arrangements by Saudi Arabia to remove the Multinational Force & Observers (MFO) from the Island of Tiran, including the removal of US troops there as part of the MFO mission, while preserving and continuing all existing commitments and procedures in the area,” it said. 

“This area of the Red Sea will now be developed for tourism and economic purposes, contributing to a more secure, peaceful and prosperous region.” 

The US-Egyptian-Israeli-backed MFO was founded in 1981 to oversee the terms of the 1978 Camp David Accords, which included the full Israeli withdrawal from the Sinai Peninsula.

In 2016, Egypt and Saudi Arabia agreed during a state visit to Cairo by King Salman bin Abdulaziz al-Saud to develop a causeway linking the two countries across the Red Sea. 

The agreement was made as part of a broader deal that would also involve Egypt ceding the sovereignty of the two Tiran islands to Saudi Arabia.

While details of the proposed crossing were never revealed at the time, it was understood to be a revival of a $4bn project announced in 2011. That scheme involved building a 32km crossing stretching over the Straits of Tiran from Ras Humaid in Tabuk, in the northern region of Saudi Arabia, to Ras Nasrani, close to the Egyptian resort of Sharm el-Sheikh.

Plans to link Saudi Arabia and Egypt are far from new. The development of a causeway was first mooted as far back as 1988. However, the idea has received additional focus in recent years following the launch of the Neom development in northwestern Saudi Arabia, which includes Ras Humaid. Part of the Neom scheme, the 170km-long linear city known as The Line, will extend from the promontory inland to the city of Tabuk.

UK-based Arup was reported to have been selected in 2019 for the next stage of the feasibility study for the causeway. 

Saudi Arabia was understood to be considering using a public-private partnership (PPP) model for the scheme, similar to other transport projects planned in and around the kingdom.

 Yemen-Djibouti causeway

A 28.5km causeway was planned to connect Yemen and Djibouti before the scheme was put on hold in 2010 until the governments of both countries signed the framework agreement for the project. The civil war in Yemen means it is unlikely the scheme will make any progress soon.

The estimated $20bn first phase involved building the link between the Yemeni mainland to the island of Perim in the Red Sea. Phase two would have then connected Perim with Djibouti.

The wider project also involves building two cities at each end of the link. The total investment required to construct the cities and the bridge is $200bn.

Dubai-based Al-Noor Holding Investment Company was developing the project.

In 2009, the company said it expected to award a build-operate-transfer contract for the first phase of the bridge and that three companies had expressed interest in funding and building the road and rail link. Denmark’s Cowi prepared the preliminary design for the crossing.

 UAE-Qatar causeway

In 2005, Abu Dhabi and Doha were reported to have been setting up a joint company to oversee the implementation of the proposed UAE/Qatar causeway.

The 40km causeway was expected to start near Sila in Abu Dhabi emirate and extend to the south of Doha.

The estimated $13bn crossing would have significantly cut journey times. At present, traffic between Qatar and the UAE has to pass through 125km of Saudi Arabian territory.

The scheme stalled shortly afterwards. Problems included difficulties with the route, which ran through Saudi Arabian territorial waters.

  • Adnoc steps up crude expansion

    15 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 contract

    15 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 processing

    15 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 plant

    15 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 complex

    15 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.
