Traffic drives construction underground

3 April 2025

 

On 14 February, Dubai construction was thrust again onto the global stage when Elon Musk, the world’s richest man, announced plans to explore the development of an underground Dubai Loop transportation system, along the lines of the Las Vegas Convention Centre Loop project in the US.

Dubai has typically made headlines globally by constructing the world’s tallest towers. As the city becomes increasingly congested on the surface, it is taking some of its largest construction projects underground.

With Musk’s backing, the Dubai Loop scheme is the most high-profile tunnelling project launched to date. It involves carving a futuristic transport system underneath Dubai. The initial phase of the project is currently being studied by Dubai’s Roads & Transport Authority (RTA) in partnership with The Boring Company, which is owned by Musk. It will cover 17 kilometres (km) and have 11 stations, with the capacity to transport over 20,000 passengers an hour.

The project highlights the importance of expanding underground infrastructure in the Middle East region. This is mostly necessitated by the pressure that rapidly growing cities have put on existing transport and utility networks, particularly in major urban centres such as Dubai, Riyadh and Doha.

Underground opportunities

Projects that involve tunnelling, such as metro rail systems, underground highways and pedestrian walkways, are deemed key enablers in reducing congestion and optimising land use.

The recently completed metro systems in Riyadh and Doha are examples of how underground rail networks can facilitate efficient urban mobility, and more such schemes are planned. 

Without these subterranean projects, cities risk being stuck in a permanent state of gridlock, with longer commute times and decreased productivity. At the same time, tunnelling allows urban planners to integrate sustainable transport solutions, as well as large-scale utilities networks, without disturbing existing cityscapes, thereby enhancing connectivity and economic growth.

These developments signal a major shift in engineering priorities, with regional governments investing in underground transport, sewerage and metro extensions to accommodate their growing populations and infrastructure needs.

While the tower crane-dotted skylines of urban centres in the GCC attract attention, delivering major projects underground is an equally impressive engineering feat. Tunnelling under busy cities requires advanced excavation techniques, careful planning and coordination to avoid disruptions.

More tunnelling work is expected as Dubai takes another significant step forward in tackling its ongoing traffic problems [with] a new metro link

UAE tunnelling projects

Tunnelling work forms a significant portion of the Dubai Metro Blue Line extension. Awarded in December for AED20.5bn ($5.5bn), the project includes 15.5km of underground track and five subterranean stations. When operational in 2029, the Blue Line will significantly expand Dubai’s metro capacity, linking major residential and commercial hubs.

More tunnelling work is expected as Dubai takes another significant step forward in tackling its ongoing traffic problems by starting the procurement process for its next metro link: the Gold Line.

Although the technical details of the project have yet to be revealed, it is expected that tunnels will form a major component of the scheme given that the new line will run through busy urban areas where there is little space to build overground. 

The Gold Line will start at Al-Ghubaiba in Bur Dubai. It will run parallel to – and alleviate pressure on – the existing Red Line, before heading inland to Business Bay, Meydan, Global Village and residential developments in Dubailand.

As a first step, the RTA has sent a request for proposals to companies for the lead consultancy role on the multibillion-dollar project.

The UAE’s Etihad Rail also began a study of the tunnels required for the high-speed railway line connecting Abu Dhabi and Dubai in January. The survey works are ongoing on the Jaddaf and Dusup tunnels that will serve the high-speed rail link. Initial plans for the project include tunnelling works totalling 31km.

Another major tunnelling project in the UAE is the $22bn Dubai Strategic Sewerage Tunnels scheme. The client, Dubai Municipality, is preparing to tender its first packages, which include deep tunnels that will stretch 42km in Jebel Ali and 16km in Warsan.

The project will be delivered under a public-private partnership model, with international consortiums competing for contracts. Once completed, these tunnels will replace the traditional wastewater network, reducing energy consumption and enhancing long-term sustainability.

Saudi schemes

In Saudi Arabia, Riyadh is preparing to expand its metro network with the addition of a Line 7 and an extension to the existing Line 2.

The total length of Line 7 will be about 65km, of which 47km will be underground. The line will have 19 stations, 14 of which will be underground.

The project involves constructing a metro line linking the Qiddiya entertainment city development, King Abdullah International Gardens, King Salman Park, Misk City and Diriyah Gate. 

In March, the Royal Commission for Riyadh City (RCRC) gave consortiums until 15 June to submit their bids for a design-and-build contract for the construction of Line 7.

The planned Line 2 extension is 8.4km long, of which 7.1km is underground, and three out of its five stations will be built underground. The RCRC is expected to award the construction contract this year.

In January, the kingdom also completed the phased roll-out of the Riyadh Metro network. The current network comprises six lines spanning about 176km, of which 74km is constructed underground.

These numbers indicate that over 42% of the overall network is underground, highlighting the growing importance of tunnels in the kingdom’s plans to improve infrastructure in its most densely populated cities.

Tunnelling works are also a key component of the plans to improve the stormwater drainage system in Jeddah, where the municipality is preparing for the construction of the King Abdullah Road-Falasteen Road tunnel.

The three-year scheme involves constructing 5.3km of tunnels with an internal diameter of 7.2 metres using tunnel boring machines (TBMs) and another 3.4km of tunnels with a diameter of 3.5 metres driven by pipe jacking or TBMs.

At the kingdom’s Neom gigaproject, city planners are looking to find solutions to many of the problems faced in existing cities and, as a result, tunnels and large-scale underground utilities corridors are being built at the beginning of the project. For example, the development’s Delta Junction tunnels will serve as a railway junction connecting the Spine infrastructure corridor with the Neom Connector rail link to the Oxagon industrial zone. 

The project involves 26.5km of tunnelling work that will be split into a north and a south lot. The construction works are expected to begin this year as the client is evaluating the revised proposals submitted by firms in November last year.

Kuwait Metro will feature extensive tunnelling … ensuring minimal disruption to existing roads while integrating with future transport networks

Further tunnel projects

Beyond the Gulf, Egypt has a long history of tunnelling projects, as it has had to deal with crippling congestion and urban overcrowding for decades. In the 1980s, work was completed on two major projects that involved tunnelling: the first phase of the Cairo Metro system and the Greater Cairo wastewater project, which involved the construction of sewage tunnels on the east and west banks of the Nile. 

Today, Cairo’s tunnelling projects include the Cairo Metro Line 4 project. Spanning 42km with 39 stations, it involves over 20km of tunnels.

Meanwhile, in Morocco, national railway operator L’Office National des Chemins de Fer (ONCF) is constructing a tunnel project in Rabat.

In February, ONCF announced a 3.3km tunnel to be constructed under the Bou Regreg river at an estimated cost of MD1.4bn ($140m). The tunnel will connect the Sale and Agdal stations in an effort to alleviate traffic.

Similarly, the long-awaited Kuwait Metro will feature extensive tunnelling to navigate the dense urban fabric of Kuwait City, ensuring minimal disruption to existing roads while integrating with future transport networks. 

Qatar’s expansion of Doha Metro, meanwhile, requires additional underground infrastructure to connect developing areas and support the country’s vision for a comprehensive public transport system. 

Mecca Metro, already serving millions of pilgrims, is also set for further expansion, likely involving significant tunnelling to facilitate smoother access to holy sites while overcoming geographic constraints. 

In Oman, the Muscat Metro project is likewise expected to link key districts while preserving the city’s landscape and avoiding disruptions to arterial roads by introducing underground sections. 

All of these projects show that tunnels will play an important role in the region’s future as it strives to create cities with more efficient and environmentally sustainable transit and utilities systems.

  • Operational resilience is now the Gulf’s real energy test

    7 April 2026

     

    For the past few weeks, the Gulf energy story has been told mostly through the lens of damage. That is understandable. We have seen attacks on industrial sites, ports and tankers, while the Strait of Hormuz remains the key constraint on exports and recovery. Around a fifth of global oil normally passes through the strait, and the latest attacks have again underlined how exposed regional and global markets remain to disruption in that corridor.

    But the more useful question now is not simply what has been hit. It is what still works, what can be rerouted, and how fast operators can adjust.

    Impact scale

    The current estimate is that the physical impact of this conflict now likely exceeds the energy industry impairments sustained during the 1990-91 Gulf War, including both physical damage and business interruption. This is a serious shock, and it will feed through into global inflation, insurance pricing, financing costs and downstream supply chains.

    This is why the story extends beyond oil and gas. Metals, aluminium and petrochemicals are part of the same resilience test. In energy-intensive industries, even a short interruption to power or logistics can create outsized losses. Aluminium is a clear example. Once power is curtailed for too long, the restart problem becomes expensive very quickly.

    But that does not mean the Gulf’s energy system has been structurally broken. A great deal of productive capacity, logistics infrastructure and operational capability remains in place. The real question is not whether the region can function at all, but how far operators can adapt, reroute and preserve output while the disruption continues.

    The physical impact of this conflict now likely exceeds the energy industry impairments sustained during the 1990-91 Gulf War

    What gives me some confidence is that the region is not standing still. Good operators are doing what good operators tend to do under pressure. They are changing production plans, prioritising domestic demand where needed, rerouting logistics and shifting product slates. In petrochemicals, some producers can move from liquid output to solid output, which is easier to truck overland and export through alternative routes. In plain terms, they are trying to keep molecules moving.

    Others are bringing planned maintenance forward. If an asset cannot export efficiently today, using this period for a turnaround can preserve future production once routes reopen. That does not remove the loss, but it can turn part of it into a timing effect rather than a permanent one.

    Risk management

    Insurance is part of that resilience equation, too. Cover is never uniform across the market, because it reflects each operator’s risk appetite. Some businesses are well protected, while others have chosen to retain more risk. In these situations, more proactive risk management actions may be preferred, such as moving inventory, reducing throughput and process operating severity [intensity] to add resiliency to energy infrastructure in case of damage.

    Prior investment in resilience is also showing its value more broadly. That includes pipeline networks, flexible logistics, broader product portfolios, experienced operating teams and, in some cases, stronger risk transfer strategies. The businesses under the most pressure are those still heavily reliant on moving bulk liquids through constrained maritime channels and with fewer options when disruption hits. Those with more routes, products and risk flexibility are coping better.

    None of this should be mistaken for complacency. Recovery will take time. Even when conditions improve, shipping patterns will not normalise overnight. The losses are real, and the fallout will be global. But this is no longer only a damage story. It is a test of operational resilience, and so far the region is showing it has more of that than many assume.

  • Adnoc Gas to rally UAE downstream project spending

    7 April 2026

     

    Despite the impact of recent Iranian attacks on its assets, the gas processing business of Abu Dhabi National Oil Company (Adnoc Gas) is on course to emerge as the largest spending entity in the UAE’s downstream oil and gas sector this year.

    Adnoc Group created Adnoc Gas, which began operating as a commercial entity in 2023, through the merger of its former subsidiaries Adnoc Gas Processing and Adnoc LNG. The consolidation of Adnoc’s gas processing and liquefied natural gas (LNG) operations formed one of the world’s largest gas processing entities, with a capacity of about 10 billion standard cubic feet a day (cf/d) across eight onshore and offshore sites, including Asab, Bab, Bu Hasa, Habshan and Ruwais.

    The scale of its infrastructure – particularly its 3,250-kilometre pipeline network, which is being expanded under the $3bn Estidama project – positions Adnoc Gas as a critical enabler of both domestic industrial growth and export competitiveness.

    Resilience amid geopolitical risk

    The recent drone-related disruptions highlight the growing exposure of Gulf energy infrastructure to regional conflict. However, the limited operational impact reported by Adnoc Gas suggests a high degree of system redundancy and resilience, supported by networked infrastructure and diversified processing capacity.

    This resilience is crucial as the company pushes ahead with its $20bn-$28bn capital programme for 2023-29. Continued investment despite security risks signals confidence in both project economics and the UAE’s ability to safeguard critical assets.

    Rich Gas Development

    At the core of Adnoc Gas’ expansion strategy is the Rich Gas Development (RGD) programme, which aims to increase processing capacity by 30% by 2030.

    The RGD project will enable the development of new gas reservoirs, helping to boost gas liquids exports, support UAE gas self-sufficiency and provide feedstock to the country’s growing petrochemicals sector, Adnoc Gas says.

    The first phase of the RGD project is under construction. Adnoc Gas awarded $5bn-worth of engineering, procurement and construction management (EPCm) contracts in three tranches for phase one last June – its largest-ever capital investment.

    The contracts cover the expansion of key gas processing plants to increase throughput and improve operational efficiency across four facilities: Asab, Bu Hasa, Habshan (onshore) and the Das Island liquefaction facility (offshore).

    The first tranche, valued at $2.8bn, was awarded to UK-headquartered Wood for the Habshan facility. The company said the contract value includes pass-through revenue and that it expects to recognise about $400m in EPCm revenue.

    Wood’s scope includes upgrades and debottlenecking of the Habshan and Habshan 5 gas processing complexes and pipelines, including brownfield modifications and the installation of new facilities.

    The remaining two tranches – $1.2bn for the Das Island liquefaction facility and $1.1bn for the Asab and Bu Hasa facilities – were awarded to UAE-based Petrofac and Dubai-based Kent, respectively.

    Petrofac, separately, said it will provide EPCm services and oversee procurement and construction contracts for a new inlet facility; two gas dehydration and compression trains, each with a capacity of 420 million cf/d; and associated infrastructure at Das Island. The company will also upgrade existing facilities to increase capacity for collecting and transporting raw gas.

    RGD growth phases

    Adnoc Gas’ capital expenditure commitment of $20bn for the 2023-29 period is expected to rise to about $28bn as it targets final investment decisions (FIDs) on the second and third phases of the RGD programme in the first quarter of 2026.

    These phases involve building a natural gas liquids (NGL) fractionation train at the Ruwais facility and a new gas processing train at Habshan. Adnoc Gas has selected main contractors for EPC works on both projects, although official contract awards are pending.

    Italy’s Tecnimont has been selected for the Ruwais NGL Train 5 project, which will have a capacity of 22,000 tonnes a day, or about 8 million tonnes a year.

    China-based Wison Engineering has been selected for the Habshan 7 gas processing train. The Habshan complex is one of the largest in the UAE and the wider Middle East and North Africa region, with a capacity of 6.1 billion cf/d across five trains and 14 processing units.

    With Adnoc Group advancing its P5 programme to raise oil production capacity to 5 million barrels a day by 2027, higher volumes of associated gas are set to enter the grid. The new train at Habshan, scheduled for commissioning in 2029, will help process these additional volumes.

    Bab Gas Cap development

    As part of its upstream expansion plans, Adnoc Group is working to extract gas from four underdeveloped gas cap reservoirs at the Bab onshore field: Thammama A, B, F and H. The Thammama A, B and H reservoirs are expected to produce a combined 1.45 billion cf/d, while Thammama F is projected to produce 396 million cf/d.

    Existing processing capacity at Habshan will be insufficient to handle these volumes. As a result, Adnoc Gas plans to build new facilities to process up to 1.85 billion cf/d of additional gas.

    The company is planning a new gas processing plant in the Bab area, about 170 kilometres from Abu Dhabi, along with associated pipelines and supporting infrastructure, as part of the broader Bab gas cap development project.

    Adnoc Gas has divided the EPC scope into four packages. It completed contractor prequalification in February and is expected to issue main EPC tenders in the second quarter.

    The company’s capital expenditure commitment could exceed $30bn once it reaches FID on the Bab gas cap development, which is expected later this year.

  • Israel ramps up gas exports to Egypt

    7 April 2026

    Israel’s gas flows to Egypt have returned to pre-war levels after restarting on 4 April, helping to ease the ongoing gas shortage in the North African country.

    Around 1.1 billion cubic feet a day is being transported by pipeline from Israel’s Leviathan and Tamar gas fields, according to a Bloomberg report.

    This is the same level that was being transported prior to Israel shutting down production from its offshore gas fields due to security concerns, and halting flows to Egypt on 28 February.

    Despite having its own gas reserves, Egypt is a net importer of natural gas and has been impacted by the surge in global prices since the US and Israel started their war with Iran.

    Last month, Egypt increased the prices of several petroleum products and natural gas for vehicles due to higher global energy prices.

    On 9 March, Egypt raised the price of natural gas for vehicles by 30% to E£13 ($0.25) a cubic metre.

    Egypt’s Petroleum & Mineral Resources Ministry said the increase was introduced due to “exceptional circumstances” resulting from geopolitical developments in the Middle East and their direct impact on global energy markets.

    It said that the regional conflict had led to a significant increase in import and domestic production costs.

    Egypt, the Middle East and North Africa region’s biggest liquefied natural gas (LNG) importer, is facing uncertainty over its LNG supplies in the coming months.

    Between March 2025 and February 2026, Egypt imported 9,440 kilotonnes of LNG, with the majority purchased under short-term agreements, mainly with third parties such as trading houses.

    Last year, it was reported that Egypt had signed deals for around 150 cargoes through to the summer of 2026.

  • Egypt gas sector activity surges amid regional conflict

    7 April 2026

     

    There is a surge of activity in Egypt’s gas sector as investors pour money into boosting domestic production and the country makes deals to leverage its existing liquefied natural gas (LNG) export infrastructure.

    The increase in activity has come as the disruption to shipping through the Strait of Hormuz continues to prevent the shipment of around 20% of the world’s LNG supplies to consumer nations.

    While Egypt remains a net importer of natural gas, its geographical position, significant gas reserves and existing infrastructure, including two LNG export terminals, mean it can potentially capitalise on the current supply crunch.

    Harmattan development

    On 6 April, Arcius announced the final investment decision (FID) to develop the Harmattan gas field offshore Egypt.

    Arcius is a joint venture between UK-based BP and the UAE’s Adnoc, focused on developing gas assets in Egypt and the wider Eastern Mediterranean.

    The company acquired the El-Burg offshore concession area, which includes the Harmattan field, in February.

    An engineering, procurement, installation and commissioning (EPIC) contract for the project has been awarded to Egypt’s Enppi, while Cairo-based Petrojet and Petroleum Marine Services (PMS) have been awarded work as subcontractors.

    In a statement, Naser Al-Yafei, the chief executive of Arcius, said: “The FID to develop the Harmattan field marks an important milestone in advancing one of our first projects in Egypt toward production.”

    Idku LNG

    UK-based Shell also held a meeting with Egypt’s Petroleum Minister Karim Badawi recently, with talks focusing on increasing domestic natural gas production and utilising the Idku LNG export terminal.

    The terminal has a nameplate capacity of 7.2 million tonnes a year, but is not currently operated at full capacity.

    The Idku facility is owned by a consortium of companies, with Shell and Malaysia’s Petronas holding the biggest stakes.

    Gas corridor

    On 30 March, Egypt signed a natural gas cooperation agreement with Cyprus, laying the groundwork for a regional gas corridor that will allow Nicosia to transport its gas to Egypt to use its export infrastructure.

    The signing ceremony took place on the sidelines of a conference in Cairo, where both parties agreed to cooperate on the development and exploitation of gas resources.

    The text of the agreement focused on technical and commercial aspects of the deal, establishing a basis for future negotiations.

    Under the agreed terms, Cyprus’ gas will be processed in Egypt’s liquefaction facilities before being shipped to export markets.

    The agreement built on a memorandum of understanding (MoU) signed in February last year, in which Egypt agreed to buy gas from Cyprus’ Aphrodite field.

    Block 6

    It is also expected that Italy’s Eni, which operates Cyprus’ Block 6 concession with France’s TotalEnergies, will announce FID for the development of the Kronos field in the coming weeks.

    The field has reserves of 3.1 trillion cubic feet and, under current plans, the field’s gas will be transported to Egypt via pipeline before being exported from Egypt’s Damietta LNG terminal.

    Future investment

    As a net importer of natural gas, Egypt faces short-term economic problems due to the current high-price environment, forcing the country to pay more for energy imports.

    While this is a major setback for the country and is likely to erode its foreign currency reserves over the coming months, the current global shortage of natural gas could lead to increased investment in the country’s oil and gas sector.

    This could accelerate existing project plans within the sector as well as the development of new projects.

  • Adnoc Gas and Borouge facilities suffer Iranian attacks

    6 April 2026

    Debris from Iranian drones intercepted by the UAE’s air defence systems has caused damage at the Habshan gas processing facility operated by Adnoc Gas in Abu Dhabi, killing one person on site, as well as at the petrochemicals complex operated by Borouge.

    In a disclosure to the Abu Dhabi Securities Exchange (ADX) on 5 April, Adnoc Gas, a subsidiary of Abu Dhabi National Oil Company (Adnoc Group), said debris resulting from a successful interception by UAE air defences in the area caused damage to a limited number of facilities within the Habshan gas complex on 3 April.

    The incident resulted in the death of an engineer working at the facility for Egyptian contractor Petrojet during evacuation. Four other contractors sustained minor injuries and were discharged from hospital after receiving treatment.

    Specialised teams were immediately dispatched to isolate the affected area and begin a comprehensive assessment of the damage to the production line, which is ongoing, Adnoc Gas said.

    “We are profoundly saddened by the loss of life and extend our deepest condolences to the family and loved ones of the deceased. Our thoughts are also with the injured colleagues, and we wish them a full and speedy recovery. The safety, security and wellbeing of our people remains our highest priority,” Fatema Al-Nuaimi, CEO of Adnoc Gas, said in the filing.

    “We remain committed to delivering shareholder value. Our balance-sheet strength and capital discipline support the resilience of the company,” she added.

    Adnoc Gas further said it is meeting domestic demand in the UAE through other facilities, with no impact on customer supply. “The company continues to actively collaborate with international customers and partners where needed,” it said in its disclosure.

    The Habshan gas processing facility has been attacked at least twice in March during Iran’s ongoing war with Israel and the US.

    Borouge incident

    Authorities in Abu Dhabi reported fire damage at Borouge’s main petrochemical facility caused by fragments from a drone interception falling on the complex on 5 April. No injuries were reported, the Abu Dhabi Media Office said.

    “Production activity in affected areas has been suspended following the incident whilst damage assessment and repairs are carried out,” the company said in a filing with ADX on 6 April.

    The company also highlighted market conditions. “A global shortage of polyolefins is driving a strong recovery in prices in March, which has continued in April,” it said.

    Borouge said it remains financially positioned to manage near-term impact. “Borouge retains significant financial resilience to navigate short-term operational disruption due to its strong cash generation and significant available liquidity.”

    Borouge pointed to strong operating performance heading into the disruption. “In the first quarter of 2026, Borouge achieved high utilisation rates and was able to sell a significant proportion of its production during the month of March via alternative routes,” the statement said.
