By introducing a new busbar technology system, the terminal’s 18 RTGs will in future be powered by electricity and no longer by diesel generators.
The first stage of the project has already taken place and involved the electrification of the container yard expansion area with the system being installed in eight RTGs.
Marcelo Diniz, maintenance manager, Portonave, said: “The reasons for the change included the reduction in diesel consumption, low maintenance costs, an increase in RTG productivity, improved equipment reliability and a substantial reduction in polluting gases.”
With the conclusion of the project, the terminal’s diesel consumption will be reduced by around 62%.
“The use of diesel generators in the RTGs resulted in greenhouse gas emissions of 2.6 million tonnes per year. With the change-over, this will fall to 83,000 tonnes per year, a reduction of 98%,” added Gabriel Telles, environmental engineer.
This German designed busbar technology system is widely used in ports in Europe and Asia. It requires the installation of a set of conducting bars with steel supports throughout the entire extension of each of the terminal’s stacking areas.
Low-voltage cables conduct the electricity from the substations to the bars and to the RTGs via an automatic arm connected to the bar. This process is fully automated and requires no human intervention. There is also a safety system which avoids possible electric shocks in contact with the equipment.
