Surge Arresters

Overvoltage surge arresters (also called SPD – Surge Protection Device) are mechanisms that allow to protect electrical equipment from overvoltages by absorbing the generated current. They can also be inserted in an already existing system in order not to modify the operation of the system.

Ivory Coast Baleine – FPSO Firenze

The FPSO Florence will enable the start-up of production from the Baleine field, currently the largest hydrocarbon discovery in Côte d’Ivoire, with an estimated 2.5 billion barrels of oil in place and 3.3 trillion cubic feet of associated gas. The Baleine development is also expected to become Africa’s first net-zero upstream project. Upon its arrival in Ivory Coast, the vessel will be renamed FPSO Baleine. The unit has been refurbished and upgraded to process up to 15,000 barrels of oil per day (bbl/d) and approximately 25 million standard cubic feet per day (MMscf/d) of associated gas. All produced gas will be transported onshore through a newly constructed export pipeline.

Luanda Refinery

The expansion and modernization initiative aims to significantly increase the refinery’s petrol production capacity, quadrupling it to 450 thousand tonnes per year. As a part of this project, the Combined Cycle has been revamped to utilize hydrogen generated by the new Platforming unit. Additionally, energy production has been optimized by recycling gas, resulting in a notable reduction in polluting emissions.

Livorno ENI Refinery

The Eni refinery in Livorno, located in Tuscany, is a historic industrial site founded in 1939. Originally established as a traditional oil refinery for processing crude oil, the infrastructure is now at the center of one of the most important Italian energy transition projects, aimed at its complete conversion into a latest-generation biorefinery. Once the transformation is complete, the facility will no longer process fossil fuels, but will exclusively treat biogenic feedstocks, such as used cooking oils, waste animal fats, and agri-food industry residues, to transform them into hydrogenated biofuels. With this new industrial asset, the project pursues a twofold objective. On one hand, it aims to produce clean fuels by replacing oil with biological waste and used cooking oils; this reduces CO₂ emissions in transport and helps Eni reach the goal of net-zero emissions by 2050. On the other hand, the conversion serves to save the factory and jobs, transforming an old plant that was at risk of closure into a modern site, thereby guaranteeing employment for all workers in the Livorno area.
