Atum

Location and Geology

The Golfinho-Atum gas fields are located in the offshore Area 1 Block of the deep-water Rovuma Basin, approximately 40 kilometers off the coast of Cabo Delgado, Mozambique. The fields are situated in waters about 1,600 meters deep.

Project Overview

The Mozambique LNG project, which includes the Golfinho-Atum gas field development, involves the construction of an onshore liquefied natural gas (LNG) facility on the Afungi peninsula in Cabo Delgado. This facility will process gas from the Golfinho-Atum fields and produce LNG for export and domestic consumption.

Ownership and Operator

The project is operated by Total E&P Mozambique Area 1 Ltda, with Total holding a 26.5% interest in the Rovuma Area 1 exploration and production concession. Other partners include:

• ENH Rovuma Área Um (15%)
• Mitsui E&P Mozambique Area1 (20%)
• ONGC Videsh (10%)
• Beas Rovuma Energy Mozambique (10%)
• Bharat Petroresources Limited (BPRL) Ventures Mozambique (10%)
• PTTEP Mozambique Area 1 (8.5%).

Capacity and Facilities

The LNG facility will have two liquefaction trains with a combined nameplate capacity of 12.88 million tonnes per annum (Mtpa) in the initial phase. The facility includes gas pre-treatment facilities, full-containment LNG storage tanks, and an LNG marine terminal capable of accommodating large LNG carriers. The production capacity is proposed to be expanded up to 50 Mtpa in future phases.

Construction and Timeline

The final investment decision (FID) for the Mozambique LNG project was taken in June 2019, with construction works starting in August 2019. The project is scheduled to start production in 2024. A consortium of McDermott, Chiyoda Corporation, and Saipem is responsible for the engineering, procurement, and construction (EPC) of the onshore liquefaction plant and its support facilities.

Environmental and Regulatory Approvals

The Mozambican Ministry of Coordination of Environmental Affairs (MICOA) approved the Environmental Impact Assessment (EIA) report in June 2014. The concessions to design, build, and operate the marine facilities were secured from the Government of Mozambique in July 2017. The Government of Mozambique gave the final approval for the Area 1 Mozambique LNG development plan in March 2018.

Resource Estimates

The Offshore Area-1 is estimated to contain 75 trillion cubic feet (tcf) of recoverable natural gas resources.

Market and Export

The LNG produced will be exported to Asian and European markets, as well as used for domestic consumption in Mozambique.

Contractors and Consultants

Key contractors include the CCS JV (a joint venture of CB&I, now McDermott, Chiyoda, and Saipem) for the EPC and FEED (front-end engineering and design) of the LNG facility. Worley, a global engineering company, was contracted by Total to provide engineering and consulting services for the onshore and subsea facilities.

This project is a significant milestone in Mozambique's energy sector, marking the country's first onshore LNG facility and contributing substantially to its economic development.
