PORT OF KOPER

Almost 600 m long container terminal of the Port of Koper, consisting of four piers, is standing entirely on concrete pylons. Due to the deepening of the sea basin in the port, Luka Koper commissioned the LGB for the geomonitoring services, i.e. the monitoring of vertical and horizontal movements and deformations of the terminal, which could occur due to changes in the seabed. Throughout the terminal, rails of lifting platforms for discharging shipping containers are carried out, and any change in their position or the position of other facilities at the terminal poses a risk of injury and deformation and affects the safety of people.

We had to adapt our works to the specific working conditions at the container terminal since we should not obstruct working processes at the terminal. The terminal was rarely empty – without tied large container vessels, which prevented us from visible visions to our reference points. In addition, our measurements were also hampered by various works on the terminal, from the decomposition and loading of container ships, the removal and delivery of containers, the position of lifts, and service work. We adjusted for each series of measurements to the current situation on the terminal.

Our services consisted of observing the movements of 26 permanently stabilized control points installed on all four piers. In the initial phase of the project (2013), we established a network of reference geodetic points and stabilized control points. In order to achieve better accuracy, in the later years, the reference points were further thickened and the control points for the implementation of the monitoring were renewed.
