Misrata Free Zone announced yesterday that operational testing and trials began for the renovation and upgrade project of the control system of its port grain silos.
MFZ said this paves the way for restarting the silos for the first time in over fifteen years. Previously, grain unloading relied on direct delivery methods, bypassing the storage and handling capabilities the silos provide.
The project, it revealed, involved upgrading the control system using the Siemens S7-1500 PLC, developing the WinCC control and monitoring software, and integrating the system via a comprehensive network connecting all silo components—including grain suction units and air compressors—to ensure operational synergy, rapid response, and enhanced performance efficiency.
Additionally, the project included renewing the temperature and humidity monitoring systems and the grain level measurement systems within the storage bins. It also introduced HMI-based operation and monitoring, enabling real-time tracking of operational indicators while enhancing operational safety and ensuring the quality of stored grain throughout the storage period.
MFZ said this project marks a significant advancement in the port's grain handling infrastructure. Full silo operation will facilitate continuous 24-hour handling and storage, drastically reduce vessel handling times—cutting them by approximately 50% compared to previous methods—and boost operational efficiency, cargo throughput speed, and the port's overall capacity for receiving and handling grain.
MFZ said operational trials were conducted yesterday, involving the 'smooth and highly efficient unloading' of the Kemet Star.
