Wison Engineering has secured contracts worth approximately US$4.04 billion from ADNOC Gas for the second phase of the Rich Gas Development project at Habshan in Abu Dhabi, marking the largest EPC award in the company’s history.
The Hong Kong-listed engineering company has been awarded a US$3.9 billion engineering, procurement and construction contract for a new natural gas processing train, alongside work on a 220KV switch station.
The development forms part of Phase 2 of ADNOC Gas’ Rich Gas Development programme and will expand natural gas processing capacity at the Habshan complex.
For Wison Engineering, the contract represents a significant increase in the scale of projects it is delivering in the Middle East and strengthens its position within the region’s oil and gas infrastructure market.
The project will involve the delivery of a complete set of gas processing facilities, including gas pipelines, separation and condensate stabilisation units, acid gas removal units and deep natural gas liquids recovery facilities.
Once operational, the new processing train is expected to increase ADNOC Gas’ capacity and operational flexibility while supporting growing demand from the UAE’s downstream and petrochemical industries.
Major EPC delivery programme
Wison will be responsible for engineering, procurement and construction across what is set to be a substantial multidisciplinary delivery programme.
The company said it will draw on its experience in oil and gas processing, complex facility design, EPC execution and project management throughout the project lifecycle.
Its delivery strategy will combine local operations in Abu Dhabi with its wider international supply chain, creating a model that brings together regional execution capability with global engineering and procurement resources.
Managing those interfaces will be a significant part of delivering the programme, given the combination of processing facilities, pipelines, electrical infrastructure and associated systems included within the contract.
The award also underlines the continuing scale of capital investment taking place across the UAE’s energy infrastructure as ADNOC expands production and processing capabilities to meet domestic and international demand.
ADNOC Gas operates integrated gas processing infrastructure across the UAE and supplies natural gas and related products to industrial, energy and petrochemical customers.
The Habshan development will provide additional processing capability as part of ADNOC Gas’ longer-term growth programme towards 2030.
Wison expands Middle East presence
The contract is an important milestone in Wison Engineering’s expansion across the Middle East.
The company described the award as recognition of its engineering expertise, project management capabilities and ability to execute large-scale oil and gas developments for major international energy companies.
The scale of the contract is particularly significant. At approximately US$4.04 billion, including the switch station, the programme represents Wison Engineering’s largest EPC contract to date.
Large EPC contracts of this type require extensive coordination across engineering disciplines, procurement packages, construction activities, commissioning and supply chains, with delivery performance dependent on maintaining integration across each stage.
Wison said it intends to use its Abu Dhabi operations alongside its global supply chain to support efficient execution of the onshore development.
The company expects the project to strengthen its position in the Middle East and provide a platform for further opportunities across major oil and gas markets.
The award also adds to Wison Engineering’s international project portfolio as the company seeks to increase its involvement in large and technically complex energy infrastructure developments.
For ADNOC Gas, the project will provide additional processing capacity at one of Abu Dhabi’s major gas infrastructure locations, supporting the wider expansion of the UAE’s downstream and petrochemical sectors.
