The works that will lead to the delivery of the Atinkou project in the Ivory Coast have come to an end. The project involves the construction of a gas-fired combined cycle power plant in the city of Jacqueville, located about 40 kilometers west of Abidjan, the economic capital of Côte d’Ivoire. The plant’s total capacity will be 390 megawatts (MW), and it will be one of the largest gas-fired power plants in the country.

The Atinkou plant will use natural gas as its primary fuel to generate electricity efficiently. The project aims to diversify the country’s energy source and reduce dependence on energy imports. In addition, it is expected that the plant will help meet the growing demand for electricity in the region, supporting economic development and improving people’s quality of life.

The Atinkou project was initiated by Atinkou SA, a joint venture between Compagnie Ivoirienne d’Electricité (CIE), the national electricity distribution company of Côte d’Ivoire, and Eranove, which specialises in the development of energy infrastructure in Africa.

The power plant will be equipped with a Siemens 255 MW SGT5-4000F class gas turbine, a 135 MW SST5-3000 steam turbine and a SPPA-T3000 control system. Feed gas for the Atinkou combined-cycle power plant will be supplied by a 4.2 km long pipeline connecting the site to the Foxtrot pipeline.

The Tormene group collaborated on the project responding to different complexities that the project had to face. The intervention of our engineers was necessary by virtue of the temperature of the gas supplied by Foxtrot (65 ° C) and therefore with the main objective of ensuring the uniformity of the pressure and temperature conditions of the gas that will be used by the plant, bringing the state of the gas to a temperature appropriate to the production needs.

The presence of the production site within a protected natural area has imposed compliance with some particularly strict noise requirements, in order to protect the surrounding ecosystem. The process of designing and sizing the silencers was approached with extreme care by our team, the goal, in fact, in addition to finding optimal solutions to mitigate the noise produced by the various operations of the system, had to ensure efficient and safe operation. Special silencers have been dimensioned and installed in all the air intakes and exhausts of the PSV (Pressure Safety Valve) in order to ensure that all operations (manual or forced) that may occur within the entire production site never exceed 60 dB at the limit of the plant.

We are extremely pleased to have been able to complete our work on this project, as it is expected that the Atinkou project will contribute significantly to the improvement of Côte d’Ivoire’s energy infrastructure, a goal in full harmony with our corporate vision. In addition, the realization of a project so careful and rigid in respecting the particular conditions related to the territory, represents an important step forward in the promotion of sustainable development.

ESD SKID

GAS TURBINE CONDITIONING STATION (FGCS)

It is composed of a BEN performance heater type but with a bended special design for vibration absorption due to the fact that, for project requirements, the superheated water must go through the shell. A stainless steel filter with special high temperature coalescing cartridges is then installed to protect the turbine from possible water leakage in the heater.
