TotalEnergies Cuts Emissions and Boosts Reliability on FPSOs in Angola

TotalEnergies is implementing measures offshore Angola to cut emissions and improve reliability on FPSOs, with goals to reduce fuel gas usage and enhance power generation efficiency, potentially saving millions in maintenance costs over two decades.

TotalEnergies is pushing forward with initiatives aimed at reducing emissions and enhancing reliability on its Floating Production Storage and Offloading (FPSO) units situated off the coast of Angola, particularly in Block 17. The focus is on decreasing the reliance on fuel gas and cutting emissions linked to power generation on the FPSOs, which is critically needed for operational efficiency.

To meet the electricity demands for essential operations—like pumps and compressors—several gas turbogenerators run concurrently. However, some of these generators occasionally function below optimal levels. In response to this, the team has been implementing energy efficiency measures, introducing technologies such as LED lighting and better air filters for the turbines, which have led to promising results.

Beyond just powering the equipment, TotalEnergies is also honing in on minimizing the number of turbogenerators needed, which involves refining the power-sharing setup between the Girassol and Dalia FPSOs. This includes optimizing the high-voltage connection cable between these platforms and adjusting load-sharing on the Pazflor FPSO to elevate power output during operations.

Additionally, the company is revising its load shedding procedures across its power generation sites to enhance overall efficiency. In a noteworthy stride, they are rolling out AI-driven dynamic load shedding strategies which should provide smarter and more effective energy management.

At the end of the previous year, TotalEnergies reported that these initiatives successfully cut CO₂ emissions by 29,000 metric tons, with a goal of reaching a reduction of up to 51,000 metric tons in just one year. On top of that, the energy savings could also translate into reduced maintenance expenses, which might save the company around $13 million in the next two decades.

In summary, TotalEnergies is enhancing its offshore operations in Angola through a suite of measures aimed at reducing emissions and improving the performance of its FPSOs. With the implementation of energy-efficient technologies, optimizations in power sharing, and the introduction of AI, the company not only aims to lower its environmental impact but also to achieve significant cost savings in maintenance over the coming years.
