Discover how Seagems boosted the energy sector with an innovative operation, increasing efficiency and highlighting Brazil on the global stage.
Seagems, widely recognized for its excellence in subsea engineering, successfully completed, in the early hours of last Thursday (19), the replacement of a flexible riser at the Porto de Sergipe thermoelectric plant, located in Aracaju (SE). In fact, this operation, which is part of a strategic partnership with eneva, positions the plant as a strong candidate for the largest power generation facility in Latin America. Therefore, the riser, which is an essential component connecting subsea systems to floating structures, plays a crucial role in transferring fluids from the surface to the seabed and then to the shore.
Preparatory work for this highly complex replacement began in October, shortly after an unexpected failure in the original pipeline. This setback compromised the distribution of natural gas and integration with the Transportadora Associada de Gás (TAG) pipeline network. Seagems was therefore immediately hired to resolve the issue effectively and quickly. In addition, the team used advanced technologies to ensure the success of the operation.
Technological innovations boost operations
The new flexible riser, measuring 14'' x 90 meters, was designed to facilitate the transfer of natural gas from the FSRU (Floating Storage and Regasification Unit) vessel Energos Nanook to Eneva's thermoelectric plant, strategically located in Barra dos Coqueiros, Sergipe. In addition, the plant has a generation capacity of up to 5 GW, reaffirming its strategic role in the Brazilian energy matrix. Therefore, its implementation is a significant milestone that puts Brazil in the spotlight in the energy sector.

“This project is absolutely crucial for the region, as the plant has the potential to be the largest in Latin America in terms of installed capacity. In addition, the FSRU has an impressive storage capacity of 170 million cubic meters of liquid natural gas and regasification of up to 21 million cubic meters per day, which are significant and highly relevant parameters,” highlighted Marcos Adriano, Superintendent of Special Projects at Seagems. Therefore, the benefits are undeniable.
Safety and efficiency as priorities
To protect and ensure the full integrity of the riser, Seagems implemented custom devices that significantly facilitated its installation. In addition, the FSRU anchoring system, developed by the renowned Norwegian company APL-NOV, stands out for its cutting-edge technology, allowing free rotation around the anchoring point and substantially increasing gas transfer efficiency. As such, the project quickly became a reference in the sector, mainly for combining innovation and safety.
“This is an innovative solution that requires a high level of specialization. Seagems’ experience and know-how were crucial in ensuring the safety and efficiency of this operation,” explained Marcos. Consequently, the execution brought concrete and lasting benefits, consolidating the company’s ability to lead challenging projects.
Energy benefits and new opportunities
The successful completion of the project ensures, above all, the continuity of energy generation at the Sergipe thermoelectric plant. Furthermore, it consolidates the collaboration between Seagems and Eneva, which is already planning to expand similar projects to other regions of Brazil. In addition, during the period between contracts with Petrobras, Seagems took the opportunity to perform preventive and strategic maintenance on its vessel Esmeralda, updating certifications and ensuring its operational readiness. With this, the company is fully prepared for new challenges and future opportunities in the energy market.
Project Highlights
- Generation capacity: The plant can reach 5 GW of installed capacity. In addition, it leads in innovation and technology, standing out as a global example.
- Storage capacity: The Energos Nanook FSRU accommodates 170 million m³ of liquid natural gas, maximizing results in a strategic and efficient manner.
- Cutting edge technology: Anchoring system allows superior efficiency and safety, which in turn reduces operational risks and increases reliability.
- Engineering innovations: Riser protection devices were developed especially for the project, standing out as a competitive advantage and ensuring greater longevity for the equipment.
With this significant milestone, Seagems reaffirms its leadership in highly complex solutions in the energy sector and undoubtedly establishes a standard of excellence that will drive new contracts and expansions. Thus, the sector gains a new solid and reliable reference that symbolizes the future of energy in Brazil.
Just to correct, the generation capacity is 1,6 GW and the storage capacity is 170 thousand cubic meters of liquid natural gas.
