Angola’s Gas Processing Infrastructure Build-Out
Angola’s transition from a gas-flaring petroleum producer to a gas-monetising energy exporter requires a fundamental expansion of onshore and offshore gas processing infrastructure. The country’s gas processing capacity, historically limited to the Angola LNG plant at Soyo and associated field-level facilities, is undergoing a step-change expansion driven by government policy, operator investment, and the compelling economics of gas capture versus flaring.
The engineering, procurement, and construction (EPC) market for gas processing infrastructure in Angola represents a multi-billion-dollar opportunity spanning the current decade. From the recently completed New Gas Consortium facility to planned processing expansions, NGL extraction plants, and domestic gas distribution infrastructure, the EPC pipeline is substantial and growing.
This article profiles the active and planned gas processing projects, identifies the EPC contractors best positioned to capture this work, examines the procurement and contracting models employed, and analyses the commercial considerations for companies evaluating market entry.
Active and Planned Gas Processing Projects
New Gas Consortium Processing Facility (Soyo)
Status: Inaugurated 2025 Investment: ~$4 billion Capacity: Gas processing for power generation and domestic supply Consortium members: Chevron, TotalEnergies, Azule Energy, Sonangol
The NGC facility near Soyo represents the largest gas processing construction project completed in Angola in recent years. The plant receives gas from multiple offshore sources, processes it to pipeline quality, and distributes it for power generation, industrial use, and feedstock for the Angola LNG plant.
The NGC EPC execution involved a combination of international engineering contractors for front-end engineering design (FEED) and detailed design, Asian fabrication yards for major equipment modules, and Angolan construction labour for site works and integration. The project demonstrated both the challenges (logistics constraints, COVID-19 disruptions, workforce mobilisation) and capabilities (successful construction of a world-class facility) of major gas plant construction in Angola.
For the NGC’s role in Angola’s gas-to-power strategy, see our article on the New Gas Consortium.
Angola LNG Soyo: Debottlenecking and Potential Expansion
Status: Operational (debottlenecking under evaluation) Current capacity: 5.2 mtpa Potential expansion: Debottlenecking (10-20%) or additional train (2.5-5.0 mtpa)
The Angola LNG plant at Soyo presents EPC opportunities in two timeframes:
Near-term (2026-2028): Debottlenecking and optimisation of existing liquefaction trains, including turbo-compressor upgrades, heat exchanger enhancements, and process control optimisation. These modifications are typically executed under brownfield EPC or engineering, procurement, construction, and commissioning (EPCC) contracts, with estimated investment of $500 million to $1 billion.
Medium-term (2028-2033): A potential additional liquefaction train would represent a $5 to $10 billion EPC opportunity. The decision to proceed would depend on feedgas availability, LNG market conditions, and project economics. See our Angola LNG terminal article for capacity analysis.
Gas Gathering and Conditioning Plants (Offshore and Onshore)
Multiple gas gathering and conditioning facilities are required to collect, treat, and transport gas from offshore production platforms and subsea systems to onshore processing plants. These facilities include:
- Offshore gas compression platforms: Compression equipment installed on existing or new platforms to boost gas pressure for pipeline transport to shore
- Onshore receiving and conditioning facilities: Gas slug catchers, dehydration units, NGL extraction plants, and compression stations at pipeline landing points
- Gas metering and custody transfer stations: Measurement systems for commercial gas transfer between operators and processing entities
The aggregate EPC value of gas gathering and conditioning infrastructure is estimated at $2 to $4 billion over the current decade, with individual project values ranging from $100 million to $1 billion depending on scope and complexity.
Sanha Lean Gas Connection Processing Upgrades
Chevron’s Sanha Lean Gas Connection, operational since December 2024, includes processing modifications to existing infrastructure in the Cabinda concession area and the pipeline system connecting to Soyo. Ongoing scope includes capacity expansion and reliability improvements as gas volumes ramp from 80 mmscf/d to 300 mmscf/d.
EPC Contractors Active in Angola’s Gas Sector
Technip Energies
Technip Energies (the engineering and construction arm separated from TechnipFMC) is a leading LNG and gas processing EPC contractor globally. The company has extensive experience with Angolan projects, having participated in the original Angola LNG plant construction. Technip Energies’ capabilities span FEED, detailed design, procurement management, and construction supervision for both greenfield and brownfield LNG and gas processing facilities.
KBR (Kellogg Brown & Root)
KBR provides proprietary LNG liquefaction technology and EPC services for gas processing plants. The company’s LNG technology portfolio includes multiple liquefaction process options (propane pre-cooled mixed refrigerant, optimised cascade, and others) that can be matched to Angola’s specific feedgas composition and processing requirements.
Saipem
Saipem’s onshore EPC division has executed gas processing and LNG plant construction projects across Africa and the Middle East. The company’s modular construction approach, fabricating process modules in Asian or European yards for transport and installation at the project site, is well suited to Angola’s logistics environment, where site-built construction faces labour productivity and material supply challenges.
Samsung Engineering and Hyundai Engineering
Korean EPC contractors Samsung Engineering and Hyundai Engineering have strong track records in gas processing and LNG construction. Both companies participated in the fabrication of modules for Angola LNG and other Angolan projects. Their competitive advantage lies in integrated fabrication-installation capability, with access to large-scale shipyard facilities in South Korea for module fabrication.
Petrofac
Petrofac provides EPC and operations services for gas processing facilities, with particular strength in brownfield modifications and operational plants. The company’s asset operations business could be relevant for the operation and maintenance of new gas processing facilities in Angola.
McDermott International
McDermott provides EPC services for onshore and offshore gas processing infrastructure, including compression, dehydration, sweetening, and NGL recovery. The company’s modular execution strategy is applicable to Angola’s development requirements.
EPC Contracting Models
Gas processing projects in Angola employ several contracting models:
Lump Sum Turnkey (LSTK)
Under LSTK contracts, the EPC contractor assumes responsibility for delivering the complete facility for a fixed price. This model transfers cost risk to the contractor but commands a pricing premium to compensate for that risk. LSTK is preferred by project sponsors for well-defined scopes with limited technical uncertainty.
Reimbursable with Target Price
Under reimbursable contracting, the EPC contractor is reimbursed for actual costs plus a fee, with a target price and gain/pain sharing mechanism that incentivises cost control. This model is used for projects with greater technical uncertainty or evolving scope, where fixing the price at contract award would result in excessive contingency pricing.
Modular vs. Stick-Built Construction
A key execution strategy decision for Angolan gas processing projects is the balance between modular construction (prefabricating process modules in overseas yards for transport and installation) and stick-built construction (assembling the facility on-site from individual components).
Modular construction offers advantages in quality control, schedule predictability, and reduced dependence on local labour availability. However, it requires careful logistics planning for transporting large modules by heavy-lift vessel and places constraints on module dimensions based on available lifting and transportation equipment.
Stick-built construction maximises local content and reduces shipping costs but is exposed to site productivity risks, weather delays, and local material supply challenges. The optimal approach for most Angolan projects is a hybrid model that combines modular fabrication of complex process modules with site-built construction of structural, piping, and electrical systems.
Local Content Requirements for EPC
Gas processing EPC projects in Angola must comply with the General Law of Local Content (Law 10/22), which sets prescriptive requirements for:
- Angolan workforce participation: Minimum percentages of Angolan nationals in construction and operations roles, with targets that escalate over the project lifecycle
- Local procurement: Preference for Angolan suppliers of construction materials, commodities, and services where capability exists
- Technology transfer: Requirements for EPC contractors to invest in training and technology transfer programmes that build local engineering and construction capability
- Angolan subcontractor participation: Mandated minimum percentages of subcontract value awarded to Angolan-owned enterprises
For international EPC contractors, local content compliance typically requires establishing partnerships with Angolan construction companies, investing in workforce training programmes, and developing local supply chains. While these requirements add cost and complexity, they also create opportunities for companies that invest in building genuine Angolan partnerships.
Procurement Strategy and Supply Chain Considerations
The procurement function for gas processing projects in Angola faces unique challenges:
Import logistics: Major equipment (compressors, heat exchangers, columns, vessels) must be imported through Angolan ports, primarily Luanda and Soyo. Port congestion, customs clearance delays, and limited laydown area can create schedule-critical bottlenecks.
Equipment lead times: Gas processing equipment lead times range from 12 to 24 months for major rotating equipment (compressors, turbines) and 6 to 18 months for static equipment (vessels, columns, heat exchangers). Early procurement of long-lead items is essential for schedule compliance.
Spare parts and maintenance: Angola’s distance from major equipment manufacturing centres necessitates comprehensive spare parts inventories and maintenance capability development.

Market Outlook
The gas processing EPC market in Angola is projected to generate $8 to $15 billion in cumulative contract awards through 2035, driven by:
- LNG expansion: $5-10 billion for potential new liquefaction capacity
- Gas gathering and processing: $2-4 billion for midstream infrastructure
- Brownfield modifications: $1-2 billion for existing facility upgrades
- Gas-to-power infrastructure: $500 million to $1 billion for power plant and pipeline gas supply
For EPC contractors, the Angolan gas processing market offers a sustained pipeline of opportunities, contingent on continued government commitment to gas monetisation and a supportive fiscal and regulatory environment.
