TotalEnergies Implements Measures to Reduce Emissions and Enhance Reliability Offshore Angola

TotalEnergies is reducing emissions and enhancing operational reliability on its FPSOs in Block 17, Angola. Key measures include improving power sharing, optimizing generators, and using AI for load management. These initiatives have already cut emissions by 29,000 tons and aim for greater reductions and cost savings.

TotalEnergies is actively implementing a series of measures aimed at reducing emissions from its deepwater operations in Block 17 offshore Angola. The primary objective is to minimize fuel gas consumption and lower emissions associated with power generation on the floating production, storage, and offloading (FPSO) units. This effort is crucial, given the environmental impact related to energy use in such facilities.

To ensure the required electricity is supplied efficiently for pumps, compressors, and other critical equipment, multiple gas turbogenerators function simultaneously. Sometimes, these machines operate outside their optimal performance range, leading to increased energy consumption. The company has introduced several energy efficiency initiatives, including the installation of LED lighting systems and enhancing air filtration processes on the turbines, to curb overall energy use.

TotalEnergies is also focusing on improving the reliability of these turbogenerators. This is achieved by anticipating breakdowns and optimizing the number of machines in operation to effectively manage spinning reserves. Their strategies include better power sharing between the FPSOs Girassol and Dalia through an upgraded high-voltage power cable connection, as well as load management adjustments on the Pazflor FPSO.

Additionally, modernization of the load shedding procedures at the power generation nodes is underway. In a significant step forward, the company is looking to deploy artificial intelligence-assisted dynamic load shedding to enhance operational efficiency. By the end of last year, the emissions reduction measures had already achieved a decrease of 29,000 metric tons of CO2, presenting a considerable potential to reach a total reduction of 51,000 metric tons within the next year. Further projections suggest maintenance cost savings of approximately $13 million spread over the next two decades, underscoring the economic benefits of these environmental initiatives.

In summary, TotalEnergies is making strides in reducing emissions and improving energy efficiency on its FPSOs in Angola’s Block 17. By implementing advanced technology, optimizing power sharing, and enhancing operational procedures, the company not only aims to cut CO2 emissions significantly but also anticipates substantial cost savings over the long term. These efforts highlight a commitment to sustainable practices while maintaining operational reliability.
