Contractors confirm Adnoc contracts for Hail and Ghasha

18 January 2023

Contractors have confirmed signing a pre-construction services agreement (PCSA) with Abu Dhabi National Oil Company (Adnoc) for the onshore scope of the Hail and Ghasha offshore sour gas field development.

France-headquartered Technip Energies, South Korean contractor Samsung Engineering and Italy’s Tecnimont, which have formed a consortium for the Hail and Ghasha onshore package, have issued statements about being awarded the PCSA. The contractors revealed the value of the contract to be approximately $80m.

The onshore work on the Hail and Ghasha scheme involves the construction of a gas process plant, pipeline network and new gas gathering units.

As part of the PCSA, the contractors are required to perform initial detailed engineering and procurement services of critical long lead items.

“The PCSA scope of work also includes the preparation of an open book cost estimate for the project delivery of the onshore scope, which will be considered as part of the client’s [Adnoc] final investment decision making process,” they said in their statements.

Under the terms of the other PCSA, Italian contractor Saipem, Abu Dhabi’s National Petroleum Construction Company (NPCC) and state-owned China Petroleum Engineering & Construction Company (CPECC) will work together on the offshore package, which covers the installation of offshore platforms, gas compression facilities and more than 400 kilometres of subsea pipelines.

The offshore contractors have confirmed the value of their PCSA with Adnoc to be $60m.

Project progress

MEED in September last year reported on contractors submitting proposals for the detailed engineering work on the Hail and Ghasha megaproject as part of an early engagement process.

The PCSAs Adnoc has signed with the two consortiums are understood to be based on the proposals received last year.

The early engagement process with contractors is expected to precede the start of the full engineering, procurement and construction (EPC) execution phase of the strategic scheme.

US engineering firm Bechtel completed the project’s original front-end engineering and design (feed) in 2019, with tenders for what were four EPC packages issued soon after.

However, following the submission of commercial bids in early 2021, Adnoc opted to make 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.

As part of the optimisation process, the four original EPC packages were consolidated into two integrated offshore and onshore packages, which are now estimated to be as high as $5bn and $5.5bn, respectively, as per sources and based on the previous version of the project.

Following the award of the PCSAs, the consortiums will get to work on the detailed design aspect of their respective packages, with the aim of putting together a final offer for the main EPC work on Hail and Ghasha.

The timing of the award of the final EPC contracts is unknown at this point, but considering the fast-track execution schedule Adnoc is known to have planned for the Hail and Ghasha project, it could be expected to take place before the end of this year.

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 for executing 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 for the provision of four island drilling units. Their duration is 10 years.

Adnoc also awarded a third contract, valued at $681m, to another subsidiary company, Adnoc Logistics & Services, to provide offshore logistics and marine support services for the planned Hail and Ghasha development.

  • Oman reveals Sohar airport and Salalah Thumrait Road plans

    21 September 2026

    Oman is planning a new passenger terminal at Sohar Airport to expand regional air connectivity and strengthen the airport’s role in the national aviation network.

    According to Said Bin Hamoud Al-Maawali, Oman’s minister of transport, communications and information technology, new routes are expected to be announced before the end of the year. Potential destinations include Dammam in Saudi Arabia, Gwadar in Pakistan, and southern Iran.

    The planned terminal and additional routes will give residents of northern Oman more travel options.

    Al-Maawali also provided an update on the long-delayed Salalah-Thumrait truck road, saying the project will be procured through a conventional tendering model rather than a public-private partnership (PPP).

    In August 2023, Oman shortlisted five of eight prequalified teams to compete for the Salalah-Thumrait truck road project, which was set to be the sultanate’s first PPP road project.

    The 67-kilometre road project is specially designed for heavy vehicles. 

    The road is a key link in Dhofar’s transport network, connecting Thumrait with Salalah and supporting movement between the interior and the governorate’s main urban and economic centre.

  • ADES completes acquisition of Saipem’s Saudi drilling business

    18 September 2026

    Register for MEED’s 14-day trial access 

    Al-Khobar-based ADES Holding Company has completed a transaction to acquire Italian oil and gas contractor Saipem’s shallow-water drilling subsidiary based in Saudi Arabia.

    Under the deal, ADES Saudi, an indirect subsidiary of Saudi Stock Exchange (Tadawul)-listed ADES Holding, will acquire Saudi Arabian Saipem, which operates a fleet of five jack-up rigs.

    The fleet includes three owned rigs – Perro Negro 7, Perro Negro 8 and Perro Negro 10 – as well as two leased rigs, Perro Negro 11 and Perro Negro 13. Four of the acquired rigs operate in Saudi Arabia, while Perro Negro 10 operates in Mexico under a charter structure and retains a valid contract in Saudi Arabia.

    ADES began the transaction to acquire Saudi Arabian Saipem in June, when it was estimated to be valued at about $285m. The deal was structured on a debt-free, cash-free basis, which was to be settled entirely in cash upon closing.

    Following completion, ADES operates a fleet of 128 units, comprising 88 offshore units – including 51 premium units – and 40 onshore rigs.

    The transaction also marks ADES’ entry into Mexico, extending the company’s international footprint to 21 countries, and adds approximately SR3.7bn ($992.9m) in backlog as of the completion date.

    The purchase of Saudi Arabian Saipem by ADES Holding follows the company’s takeover of Dubai-based, Oslo-listed Shelf Drilling in November last year, in a transaction valued at $379m. Following the completion of the cash merger, Shelf Drilling was wholly delisted from the Oslo Stock Exchange.

    The combined Shelf Drilling-ADES entity has been operating as a global player in shallow-water drilling in the world’s most prolific basins, with a fleet of 83 offshore jack-ups, including 46 premium jack-ups and 40 onshore rigs. The acquisition expanded ADES Holding’ global footprint from 13 to 19 countries, allowing entry and deeper operational integration into Southeast Asia, India, West Africa, the North Sea and the broader Mediterranean.

    Saudi Arabian Saipem generated revenues of SR636m ($170m) in 2025, highlighting the scale of the business being transferred.

    The divestment aligns with Saipem’s broader industrial strategy of reducing exposure to mature shallow-water drilling markets and concentrating resources on deepwater and harsh-environment offshore projects, where technical complexity and barriers to entry are generally higher.

    These segments have attracted growing investment in recent years as operators pursue offshore developments in regions such as the North Sea, Brazil, West Africa and the US Gulf of Mexico.

    For ADES, the acquisition further expands its presence in the Middle East offshore drilling market, particularly in Saudi Arabia, one of the world’s largest offshore jack-up rig markets, driven by activity from Saudi Aramco.

    Saipem previously said proceeds from the transaction will be used in accordance with the objectives outlined in its industrial plan. The Milan-listed company was advised on the transaction by Moelis & Company as financial adviser and Clifford Chance, together with AS&H Clifford Chance, as legal counsel.

  • SAR tenders design review consultancy for GCC rail link

    18 September 2026

     

    Register for MEED’s 14-day trial access 

    Saudi Arabia Railways (SAR) has issued a request for proposals (RFP) for a design management and review consultant to oversee engineering works on the GCC railway network, the latest step in advancing the long-delayed regional rail link.

    The RFP was issued on 9 September, with a submission deadline of 18 October.

    The tender seeks a consultant to manage, audit and verify deliverables produced by SAR's separately appointed design services consultant, rather than carry out the design itself. The tendering for the design services consultancy is currently in progress.

    Construction will be tendered separately through competitive bidding once designs are approved.

    The GCC railway will run for about 672 kilometres (km) inside Saudi Arabia, linking the kingdom's existing network to Kuwait, Qatar, the UAE and Bahrain, with four sections of about 141km, 200km, 151km and 21km, respectively.

    The line is planned as a single-track, non-electrified corridor for mixed freight and passenger traffic, with a maximum axle load of 32.4 tonnes and passing loops for bidirectional working.

    The appointed consultant will develop a design management and review plan covering governance, interdisciplinary coordination and stage-gate approvals, and will issue formal review and audit reports against SAR's requirements and international standards.

    The scope also covers stakeholder engagement, interface management and oversight of land acquisition activity tied to the design consultant's land acquisition plan.

    Key design stages are expected to take about 16 months: four months for concept design, six for preliminary design and six for issued-for-construction design, each with four weeks of contingency.

    SAR has asked bidders to mobilise a core team from day one. These must include a project director, engineering and design manager, stakeholder manager and lead document controller, all based at SAR's offices, with minimum experience thresholds ranging from three years for junior operators up to 25 years, including 15 in rail, for the project director role.

    GCC railway line

    Under the overall plan, the railway will run from Kuwait, pass through Dammam in Saudi Arabia, reach Bahrain via a planned causeway, and continue from Dammam to Qatar, the UAE and, ultimately, Muscat via Sohar in Oman. The railway is reported to cover about 2,186km in total.

    The route length within each member state is as follows:

    • UAE – 684km
    • Saudi Arabia – 672km
    • Oman – 306km
    • Qatar – 283km
    • Kuwait – 145km
    • Bahrain – 36km

    The railway is designed for passenger trains travelling at 220 kilometres an hour (km/h) and freight trains operating at 80km/h–120km/h.

    With high levels of project activity, governments in spending mode and renewed cooperation under the Al-Ula Declaration, the latest efforts to restart the GCC railway project may make more progress than previous attempts. If completed, the railway could prove transformational for a region that is globally connected but still divided by national borders.

  • Tender issued for Libyan gas project

    17 September 2026

    An invitation to bid has been issued for a contract to conduct environmental assessments for the project to expand the Mellitah oil and gas complex in Libya.

    The bid submission deadline is 2pm today (17 September) Libyan time.

    The scope of the project includes provision of:

    • An environmental baseline study (EBS)
    • An environmental impact assessment (EIA)
    • An environmental management plan (EMP)

    The client is Mellitah Oil & Gas (MOG), which is a joint venture of Italy’s Eni and Libya’s National Oil Corporation (NOC).

    MOG is based in Tripoli and operates both onshore and offshore oil and gas facilities.

    The joint venture owns and operates six major oil and gas fields across the North African country.

    According to the tender documents, the company that is awarded the contract will need to prepare environmental management measures in compliance with:

    • Libyan environmental legislation
    • Ministry of Environment requirements
    • NOC environmental guidelines
    • Applicable international environmental standards and best practices

    The expansion of the Mellitah oil and gas complex is part of a project estimated to be worth $8bn.

    The wider project is known as the Mellitah Complex Expansion & CO2 Management Integrated Development Project.

    It has six main packages:

    • Onshore package
    • Offshore Structure A
    • Offshore Structure E
    • Subsea pipeline package
    • Site preparation work
    • Carbon capture and storage facility

    Security issues and political instability have been a major problem for Libya’s oil and gas sector since the country’s civil war started in 2011.

    Earlier this month, the Mellitah oil and gas complex was forced to shut down temporarily due to a protest over deteriorating public services.

    The existing onshore complex includes housing, processing units, storage facilities and export facilities.

    It also serves as the launch point for the Greenstream pipeline, which delivers Libyan gas directly to Italy.

    The planned expansion of the complex will involve:

    • Construction of a new fourth gas processing train
    • Construction of a third condensate train
    • Construction of a third natural gas liquids fractionation train
    • Construction of a fourth sulphur recovery unit train
    • Installation of a hydrogen sulphide enrichment unit
    • Installation of a sulphur recovery unit
    • Construction of other associated facilities

    The Mellitah complex is located about 100 kilometres west of Tripoli and is a key energy facility in the west of the country.
