Angola's Refinery Construction Programme: EPC Contractors and Timelines

Building Domestic Refining Capacity: Angola’s Multi-Billion Dollar Programme

Angola’s refinery construction programme is among the most ambitious downstream development initiatives in Sub-Saharan Africa. Despite being the continent’s second-largest crude oil producer, Angola imports approximately 80 percent of its refined petroleum products, an economic paradox that drains foreign exchange, creates supply vulnerability, and deprives the national economy of the value-added margin between crude oil and refined products.

The government’s response is a multi-refinery construction programme designed to progressively eliminate import dependency by 2030. The programme encompasses the recently inaugurated Cabinda refinery, the under-construction Lobito refinery, upgrades to the existing Luanda refinery, and potential additional facilities. Combined, these projects represent more than $10 billion in capital expenditure and will engage a diverse ecosystem of EPC contractors, equipment suppliers, and service providers.

This article provides a detailed project-by-project analysis of Angola’s refinery construction programme, profiling the EPC contractors involved, examining construction timelines, and assessing the challenges and opportunities for market participants.

Cabinda Refinery: The First New Refinery in Decades

Project Overview

Location: Malembo, Cabinda Province Capacity: 30,000 bpd (Phase 1), planned expansion to 60,000 bpd (Phase 2) Inauguration: September 2025 Investment: Approximately $1.5-2.0 billion (Phase 1) Ownership: Gemcorp (90%), Sonangol (10%) Crude feedstock: Light Angolan crude (Cabinda blend)

The Cabinda refinery is a landmark achievement for Angola’s downstream sector. Inaugurated in September 2025, it is the first new refinery built in the country in decades and represents a departure from the traditional model of state-led refinery development, with Gemcorp, a London-based investment firm focused on emerging markets, holding a 90 percent stake.

Refinery Configuration

The Phase 1 configuration is designed for processing light Angolan crude oils (primarily Cabinda blend with API gravity of approximately 31-33 degrees) into a product slate including:

• Gasoline (petrol)
• Diesel (gasoil)
• Jet fuel (kerosene)
• LPG (propane and butane)
• Fuel oil

The refinery incorporates:

• Crude distillation unit (CDU)
• Vacuum distillation unit (VDU)
• Naphtha hydrotreater
• Diesel hydrotreater
• Catalytic reformer
• Product blending and storage facilities

Phase 2 Expansion

Phase 2 plans call for doubling capacity to 60,000 bpd through the addition of a second crude distillation train and secondary conversion units that would enable processing of heavier crude slates and improve product yields. The Phase 2 timeline is dependent on the operational performance of Phase 1 and the availability of financing.

EPC Execution

The Cabinda refinery EPC was managed through a combination of international engineering firms for design and process licensing and a diversified procurement strategy for major equipment. Chinese engineering and construction firms played a significant role in fabrication and installation.

Lobito Refinery: The Flagship Project

Project Overview

Location: Lobito, Benguela Province Capacity: 200,000 bpd (full build-out) Estimated investment: $6.6 billion (reduced from earlier estimates of $8-12 billion) Current status: Approximately 12% complete (as of early 2026) Expected completion: Phased, with initial production units targeted for late 2020s Ownership: Sonangol-led, with potential strategic partners

The Lobito refinery is the centrepiece of Angola’s downstream ambitions. At 200,000 bpd capacity, it would be among the largest refineries in Sub-Saharan Africa and would process approximately 70 to 80 percent of Angola’s current refined product demand.

Refinery Configuration and Technology

The Lobito refinery design encompasses a full-complexity configuration capable of processing a range of Angolan crude grades:

Primary processing:

• Crude distillation unit (200,000 bpd)
• Vacuum distillation unit
• Atmospheric residue desulphurisation

Conversion units:

• Fluid catalytic cracking (FCC) unit for gasoline production
• Hydrocracker for middle distillate (diesel, jet fuel) production
• Delayed coker for residue conversion
• Alkylation unit for high-octane gasoline blending

Treating and finishing:

• Naphtha hydrotreater
• Diesel hydrotreater
• Kerosene hydrotreater
• Sulphur recovery unit
• Hydrogen generation unit

This complex configuration maximises the conversion of crude oil into high-value light products (gasoline, diesel, jet fuel) while minimising low-value residual fuel oil, optimising the refinery’s economic margin.

EPC Contractor Landscape

The Lobito refinery’s scale and complexity require a tiered EPC execution approach:

FEED and PMC: International engineering firms with refinery FEED experience are engaged for front-end engineering design and project management consultancy. Firms with relevant African refinery experience include Worley, Wood, Technip Energies, and KBR.

Main EPC packages: The refinery construction is being executed through multiple EPC packages, each covering specific process units or infrastructure:

• Process units: Major international EPC contractors (Technip Energies, Saipem, Samsung Engineering, Hyundai Engineering, CNPC Engineering) compete for the primary process unit packages
• Offsites and utilities: Power generation, water treatment, cooling systems, and utilities infrastructure
• Storage and marine: Crude oil and product storage tanks, marine loading/unloading facilities, jetties
• Infrastructure: Roads, buildings, security, accommodation

Modular fabrication: Given the logistics challenges of the Lobito site, significant modular fabrication is planned at Asian yards (South Korea, China, India) for transport and installation.

Construction Challenges

At approximately 12 percent completion, the Lobito refinery faces several construction challenges:

Financing: Securing the full $6.6 billion investment has been challenging. Sonangol’s balance sheet constraints limit the state company’s ability to self-finance, necessitating external financing from commercial banks, development finance institutions, and potentially strategic investor participation. For the broader financing context, refer to our LNG project finance analysis for parallels in gas sector financing.

Execution capacity: Managing a project of this scale in Angola requires extensive logistics planning, workforce mobilisation, and supply chain management capability. The country’s limited refinery construction experience means significant reliance on international expertise.

Timeline risk: At current completion levels, the Lobito refinery will not achieve full operations before the late 2020s at the earliest. Schedule acceleration would require resolution of financing constraints and contractor mobilisation challenges.

Luanda Refinery: Upgrade and Modernisation

Project Overview

Location: Luanda Current capacity: ~65,000 bpd (nameplate), operating at reduced capacity Operator: Sonangol Status: Operational with planned upgrades

The Luanda refinery is Angola’s only currently operational refinery (aside from the newly inaugurated Cabinda facility). Built in the 1950s and expanded in subsequent decades, the refinery operates well below its nameplate capacity due to equipment age, maintenance backlogs, and configuration limitations.

Planned Upgrades

Sonangol has announced plans to modernise the Luanda refinery, including:

• Restoration of crude distillation capacity to 65,000 bpd
• Installation of new hydrotreating units to produce cleaner fuels
• Replacement of obsolete control systems and instrumentation
• Infrastructure and safety upgrades

The Luanda refinery modernisation is estimated at $500 million to $1 billion and could be executed through brownfield EPC contracts. For the existing product distribution infrastructure that connects to this refinery, see our petroleum product distribution article.

EPC Market Dynamics and Contractor Positioning

The Angolan refinery EPC market has attracted interest from a range of international contractors:

International EPC Contractors

Chinese Contractor Involvement

Chinese EPC contractors (CNPC Engineering, Sinopec Engineering, CPECC) have been significant participants in Angola’s refinery programme. Their involvement is often linked to broader Sino-Angolan economic relationships, including Chinese infrastructure financing and crude oil supply agreements. Chinese contractors offer competitive pricing and rapid mobilisation capability, though quality management and technology transfer aspects require careful contract structuring.

Local Content in Refinery Construction

Refinery construction in Angola is subject to stringent local content requirements under Law 10/22. Key obligations include:

• Angolan national employment targets for construction and operations roles
• Local subcontractor participation in civil works, structural steel, and non-specialist services
• Procurement of locally available materials (cement, aggregate, structural steel fabrication)
• Training and technology transfer programmes

For international EPC contractors, local content compliance requires early engagement with Angolan subcontractors, investment in training infrastructure, and adaptation of project execution strategies to incorporate local resources.

Timeline Summary

If all projects are completed on the current indicative timelines, Angola’s total refining capacity would increase from approximately 65,000 bpd (pre-2025) to approximately 325,000 bpd, transforming the country from a major refined product importer to a largely self-sufficient or even surplus refining market.
