ArcelorMittal supplies hot-rolled steel sheet piles to largest thermoelectric gas plant in Latin America


ArcelorMittal supplies hot-rolled steel sheet piles to largest thermoelectric gas plant in Latin America

ArcelorMittal Projects Central & South America is participating in the construction of the Sergipe Thermoelectric Power Plant; part of the largest thermoelectric gas complex in Latin America.

Starting from January 2020, the plant will generate 1,500 gigawatts (GW) - enough to meet 15% of the energy demand in Northeast region of Brazil.

It started with a visit from our commercial team to the jobsite in Barra dos Coqueiros, Sergipe state, conducting a series of studies to check on the technical and economic feasibility for the temporary use of steel sheet piles. We successfully rented 400 tons of sheet piles which are being used as a temporary retaining wall during excavations for the construction of the cooling tower, pump house and drainage boxes.

There were several factors influencing the selection of the steel sheet pile solution. Firstly, the increase in productivity due to the speed of execution using vibratory hammer is noteworthy. Secondly, a lean work with a prefabricated product is highly necessary due to the size of the project, lowering the amount of manpower required from the contractor.

Furthermore, the location of the stocks is near to the jobsite - 460km when dealing with the size of Brazil is a relatively short distance. Together, these advantages reduced the cost of the project in comparison with the other solutions.

Background information: Energy security for the Brazilian Northeast

The Sergipe Thermoelectric Power Plant located in Barra dos Coqueiros, in the metropolitan region of Aracaju (SE), will receive investments of USD 1,5 billion. It is part of the Governor Marcelo Déda Power Generation Complex, which intends to have two thermoelectric generation plants; UTE Marcelo Déda and UTE Laranjeiras, generating up to 3,000 GW of energy. This project will play a strategic role in reducing the risk of blackouts caused by the five-year drought in the Northeast.
