How Eni’s Congo LNG Phase 2 Sets a New Benchmark in FLNG Deployment

Eni has launched Phase 2 of the Congo LNG project earlier than scheduled, following the arrival of the Nguya FLNG unit and the introduction of gas into the newly built offshore system. The project’s accelerated start-up—achieved just 35 months after construction of the Nguya FLNG began—positions Eni among the fastest in the industry at delivering full-scale floating liquefied natural gas (FLNG) infrastructure.

Expanded Capacity Through an Integrated Offshore System
Phase 2 raises the project’s total capacity to 3 million tonnes per annum of LNG, equivalent to 4.5 billion cubic meters of gas per year. This expansion is enabled by three new production platforms, the Scarabeo 5 gas treatment and compression unit, and the Nguya FLNG for liquefaction and export. The configuration allows flexible and phased management of gas volumes from the Nené and Litchendjili fields in the Marine XII license, ensuring continuous supply to both the Nguya FLNG and the Tango FLNG, which began operations in late 2023.

Designed for Flexibility, Efficiency, and Lower Carbon Impact
The Nguya FLNG, measuring 376 meters in length and 60 meters in width, is engineered to process gas with varying compositions and incorporates technologies that reduce its carbon footprint. Its versatility provides a platform for future field developments. The Scarabeo 5 unit—repurposed from a drilling rig—integrates decarbonization-oriented systems, illustrating Eni’s approach to circular economy engineering and cost-efficient asset reuse.

A Differentiated Approach: Local Execution and Accelerated Delivery
A substantial portion of Phase 2 was executed within the Republic of the Congo, strengthening local industrial capacity and expanding workforce expertise. This localized development model, combined with rigorous planning and technological innovation, is central to why Eni achieved a milestone that outpaces typical FLNG project delivery times in the sector.

Contribution to Congo’s Energy System and Long-Term Gas Strategy
Eni has operated in the Republic of the Congo for more than five decades and plays a key role in developing the country’s natural gas resources. It supplies the Centrale Électrique du Congo, which generates around 70% of national power, and supports modernization of the electricity transmission network, including upgrades to the high-voltage line linking Pointe-Noire and Brazzaville. Beyond gas, Eni is advancing energy-transition initiatives such as an agri-feedstock program integrated into the biofuel supply chain, along with broader community development efforts focused on energy access, water, healthcare, and economic diversification.
