Upper Zakum offshore expansion project has entered a critical construction phase after ADNOC selected contractors for several major engineering, procurement, construction, and installation packages. The development, valued at more than $10 billion, aims to increase production capacity at one of the world’s largest offshore oil fields. Consequently, the project will drive extensive offshore construction activity across Abu Dhabi while supporting the UAE’s long-term energy strategy.
The latest contractor selections mark a significant step toward full-scale execution. Moreover, the awards cover key offshore facilities, production infrastructure, utilities, pipelines, and associated installations required for the next stage of field development. Industry sources indicate that ADNOC completed detailed evaluations before selecting preferred contractors for the massive offshore program.
The Upper Zakum offshore expansion project forms part of ADNOC’s broader strategy to increase production capacity and strengthen operational efficiency. Furthermore, the field remains one of the most important offshore assets in the UAE’s upstream portfolio.
Upper Zakum Offshore Expansion Project Moves into Major Construction Phase
Construction activities will focus on expanding offshore processing facilities and supporting infrastructure. In addition, contractors will deliver new wellhead facilities, utility systems, water injection facilities, pipelines, and brownfield integration works.
The project targets production capacity of up to 1.5 million barrels per day. Therefore, ADNOC plans to execute multiple engineering and construction packages simultaneously to accelerate delivery.
Several artificial islands will also support the expansion program. These facilities have already proven effective in reducing environmental impacts while enabling large-scale offshore construction. Consequently, ADNOC continues to use the island-based development model for future growth.
Meanwhile, contractors will undertake extensive fabrication, transportation, installation, and commissioning activities. The works will require specialized marine vessels, offshore lifting equipment, and advanced engineering expertise.
The contractor selections also create opportunities for suppliers, fabrication yards, logistics providers, and technology companies. As a result, the project is expected to generate significant economic activity throughout the regional energy supply chain.
Upper Zakum Offshore Expansion Project Supports Long-Term Production Growth
The expansion project supports ADNOC’s wider objective of maintaining reliable energy supplies while enhancing production efficiency. Additionally, the company continues to integrate advanced technologies into offshore operations.
Artificial intelligence, automation systems, and digital monitoring technologies are expected to play major roles during project execution and future operations. Therefore, the development aligns with ADNOC’s efforts to modernize its offshore assets.
Strategic partners including ExxonMobil and INPEX remain involved in the Upper Zakum development. Their participation provides technical expertise and supports the project’s phased delivery strategy.
Industry analysts view the project as one of the largest active offshore construction programs globally. Furthermore, the development represents a major component of ADNOC’s multibillion-dollar project pipeline extending through 2027.
Offshore Construction Demand Expected to Accelerate
With contractor selections now progressing, offshore construction activity is expected to increase substantially over the coming months. Moreover, fabrication yards and marine contractors are preparing for higher workloads as project execution advances.
The phased development approach allows ADNOC to maintain existing production while expanding capacity. Consequently, the company can minimize operational disruptions during construction.
As additional packages move toward award and execution, the Upper Zakum offshore expansion project will remain one of the Middle East’s most closely watched energy construction developments. The project’s scale, technical complexity, and strategic importance continue to attract leading international contractors and engineering firms.
The award activity also reflects a broader trend across the Gulf’s offshore energy sector. Recently, Saudi Aramco advanced offshore development works worth $1.7 billion through contracts awarded to preferred bidders, highlighting continued investment in large-scale marine infrastructure projects. Together, the Aramco and Upper Zakum developments demonstrate how national oil producers are expanding offshore capacity while creating substantial opportunities for engineering, fabrication, and marine construction contractors across the region.
