The Umm Shaif Gas Cap project is advancing through major engineering and construction appointments following ADNOC’s $6.2 billion final investment decision. The offshore development in Abu Dhabi has moved beyond investment approval, with contractors securing key engineering, procurement, construction and installation responsibilities. In July 2026, ADNOC confirmed the investment alongside international concession partners. The development targets more than 600 million standard cubic feet of gas daily by 2030.
The latest contractor appointments provide greater clarity on the infrastructure delivery program. Larsen & Toubro Energy Hydrocarbon Offshore (LTEH Offshore) secured an ultra-mega order from ADNOC Offshore on August 4, 2026. The company will lead a consortium responsible for developing multiple offshore facilities and upgrading existing infrastructure.
Importantly, L&T has not disclosed the precise contract value. Its ultra-mega classification applies to orders exceeding INR15,000 crore. Therefore, the previously reported $1.75 billion figure should not be presented as a confirmed contract value.
Umm Shaif Gas Cap project advances through offshore engineering
The L&T-led consortium will execute the major share of its assigned EPCIC scope. This covers engineering, procurement, construction, installation and commissioning of offshore facilities. Additionally, the contractor will undertake modifications and upgrades to existing infrastructure.
A significant portion of fabrication will take place at L&T’s fabrication yards. The company will also deploy its engineering capabilities and dedicated marine fleet. Furthermore, its integrated delivery approach will coordinate fabrication, transportation and offshore installation activities.
The engineering program gained another milestone on August 26, 2026. Technip Energies secured a detailed engineering services contract from L&T Energy Hydrocarbon. The appointment covers engineering services for the offshore development’s first package.
Technip Energies will draw on its regional engineering capabilities and experience delivering complex offshore infrastructure. The appointment also strengthens coordination between engineering and construction teams before offshore installation.
Meanwhile, McDermott confirmed another major construction appointment on August 24, 2026. The company secured an EPCI contract for Package 4 of the Umm Shaif Integrated Gas Cap and Surface Pressure Boosting project. Its Qingdao McDermott Wuchuan consortium will deliver a new surface pressure-boosting facility.
The scope includes a jacket, topside and associated modifications to existing offshore infrastructure. McDermott expects the completed topside to rank among the Middle East’s heaviest offshore modules. Fabrication will take place at its Qingdao joint venture facility in China.
Umm Shaif Gas Cap project targets 2030 gas production
ADNOC approved the $6.2 billion development on July 21, 2026. The investment includes three major EPC packages worth approximately $5.1 billion. Additionally, ADNOC Drilling secured a $365 million contract covering 14 wells and integrated drilling services.
The drilling program will run for 18 months using three existing rigs. The wider development will unlock more than 600 million standard cubic feet of natural gas daily. It will also increase associated gas liquids production. First production remains targeted for 2030.
The infrastructure program will support gas recovery from ADNOC’s longest-operating offshore field. Furthermore, additional supplies will strengthen domestic energy availability and support industrial expansion. ADNOC expects the development to contribute almost 10% of current UAE daily gas consumption.
The project also forms part of the company’s wider gas expansion strategy. Its investment program includes other developments targeting unconventional and conventional gas resources. The Ruwais Diyab Gas Development is another major initiative, targeting initial production of 345 million standard cubic feet daily from 2029. Together, these developments demonstrate ADNOC’s expanding investment in gas production and associated infrastructure.
However, the offshore program still requires extensive fabrication, installation and commissioning work. Contractors must coordinate multiple engineering packages and specialized marine operations. Consequently, successful integration will remain essential to achieving the 2030 production target.
ADNOC Offshore construction project strengthens regional offshore capacity
The EPCIC scope includes detailed engineering, procurement of equipment, fabrication of offshore structures, transportation, offshore installation and final commissioning.
These integrated activities will allow construction teams to deliver complete offshore facilities under a single execution framework.
The project will draw upon modern fabrication yards, specialized marine vessels and experienced offshore engineering teams.
Additionally, integrated project management will help coordinate fabrication and offshore installation schedules, reducing execution risks throughout construction.
ADNOC continues investing heavily in offshore developments as demand for reliable energy remains strong. Recently, the company approved major investments across its gas portfolio, including the $6.2 billion Umm Shaif Gas Cap development.
Those investments demonstrate ADNOC’s commitment to expanding offshore production while supporting domestic industrial growth.
The latest contract also expands one of the largest offshore order books in the Middle East. As a result, regional supply chains, fabrication facilities and marine contractors are expected to benefit from sustained construction activity over the coming years.
ADNOC Offshore construction project supports long-term energy expansion
The award highlights growing demand for integrated EPCIC contractors capable of delivering increasingly complex offshore developments.
Modern offshore projects require coordinated engineering, digital planning, advanced fabrication techniques and specialized marine installation capabilities.
Therefore, integrated execution has become increasingly important for reducing costs and shortening project schedules.
The Middle East remains one of the world’s busiest offshore construction markets. Continued investment by national energy companies supports new platforms, subsea infrastructure, brownfield upgrades and production enhancement projects.
Consequently, contractors with proven offshore experience continue securing large-scale contracts across the region.
This latest development also reinforces Abu Dhabi’s position as a global offshore energy hub. By expanding offshore infrastructure today, ADNOC aims to meet future energy demand while improving production resilience and operational efficiency.
The project therefore represents another significant investment in the UAE’s long-term energy infrastructure program.
Construction activities are expected to progress through engineering, fabrication, offshore transportation, installation and commissioning phases before the facilities enter operation. Throughout delivery, project teams will prioritize safety, quality assurance and environmental compliance while coordinating work across multiple offshore locations.
The award also reflects the sustained wave of EPC investment across the Gulf’s energy sector. Similarly, the Fadhili Gas Plant expansion project in Saudi Arabia continues advancing through major EPC packages, highlighting how national energy companies are accelerating large-scale gas and offshore developments to strengthen production capacity and long-term energy security.
