Italian engineering firm Rosetti Marino has completed the construction of the jacket and topside for the Fenix wellhead platform, which are now headed to Tierra del Fuego in southern Argentina.
Rosetti Marino built Fenix platform’s topside and jacket for TotalEnergies’ Fenix gas development project as part of an engineering, procurement and construction (EPC) contract awarded in 2022.
A four-legged jacket, weighing 1,537 tons, will be installed in about 71 m water depth with associated infrastructure such as piles, disposal tube, anodes, including pre-installed risers, Jtubes and facilities for future subsea wells.
The jacket and 1,385-ton topside were safely loaded onto the Interocean II heavy transport vessel, leaving for Argentina on Jan. 8, according to a Rosetti Marino LinkedIn post.
In September 2022, TotalEnergies approved the final investment decision (FID) for the Fenix gas development, which is 60 km off the coast of Tierra del Fuego.
TotalEnergies operates the project with a 37.5% interest through its Total Austral affiliate, in partnership with Wintershall Dea (37.5%) and Pan American Sur (25%).
The Fenix Field will be developed through three horizontal wells, and the gas will be transported through a 35-km pipeline to the TotalEnergies-operated Véga Pleyade platform.
At production startup, planned for early 2025, Fenix is expected to produce 10 MMcm/d of natural gas (70,000 boe/d).
The development represents an investment of about $706 million.
In September 2023, Wintershall Dea issued a brief update on the Fénix subsea development in the Cuenca Marina Austral 1 (CMA-1) concession offshore Argentina. The comapny said work on Fénix is progressing as planned, with the first concrete blocks that will support the subsea pipeline installed on the seafloor in July 2023. At the time, laying of the subsea pipeline that will connect the future Fénix platform to the existing Vega Pléyade platform had begun.
