TotalEnergies Implements Emission-Reducing Measures on FPSOs in Angola

TotalEnergies is reducing emissions and enhancing reliability on its FPSOs in Angola by implementing various energy efficiency measures and optimizing power management. These initiatives have already cut CO2 emissions significantly and are projected to lower costs substantially over time.

TotalEnergies is actively implementing a series of measures aimed at reducing emissions in its offshore deepwater field developments, particularly in Block 17, Angola. The primary goal is to lower fuel gas consumption and decrease emissions tied to power generation aboard its floating production, storage, and offloading units (FPSOs).

The FPSOs rely on multiple gas turbogenerators to provide electricity for various operations, including pumps and compressors. However, these machines sometimes operate outside their optimal efficiency range. In response, TotalEnergies has initiated energy efficiency upgrades, such as employing LED lighting and enhancing turbine air filters to curb energy consumption.

Additionally, the company is focusing on boosting the reliability of the turbogenerators while also anticipating potential malfunctions that might arise. Efficient load management is being enhanced, especially through better power sharing between the Girassol and Dalia FPSOs by optimizing the high-voltage cable interlinking them. Moreover, improvements in load-sharing management are in place for the Pazflor FPSO turbogenerators to elevate their operational power output.

Another critical step involves revising the load shedding protocols across the power generation nodes. As part of a modern approach, the organization is also introducing AI-assisted dynamic load shedding which is expected to elevate operational efficiencies further. By the end of last year, these efforts led to a substantial cut of 29,000 metric tons in CO2 emissions, with a long-term potential to decrease emissions by a total of 51,000 metric tons within a year. Besides environmental benefits, the anticipated reduction in maintenance costs is projected to reach about $13 million over the next two decades.

In summary, TotalEnergies is making significant strides in reducing emissions and improving the operational reliability of its FPSOs in Angola. With initiatives like energy efficiency upgrades, improved load management, and the incorporation of AI technology, the company not only aims to enhance its environmental performance but also create substantial cost savings over the coming years.
