The upper level of the Limenas Quay is + 1.50m. by the MSF and the useful depth is between 7.50-8.00m. The total length of the quayboats that berth ships is 1037m. It has two weighbridges for weighing the moving loads. The main loads serviced in the installation are iron products, fertilizers, glass sand etc.
