The contract is put into service for the Port of Zeebrugge ProToel program developed in a previous command "Research for the development of a probabilistic admittance policy to the Flemish ports" by the Department of Marine Technology at Ghent University. This program calculates the prediction of the risk of touching bottom by normative ships when sailing through the Scheurpas and Pass Sand, under different conditions of sea state, speed and under keel clearance, flow and influence of the mud layers. It would allow the departments Shipping Assistance and Pilot after rollout essentially determine the arrival or departure of a tidal ship to the Port of Zeebrugge as probabilistic planning principles and tide windows. The expansion of the database of vertical ship movements through model tests and calculations for the larger container ships to call at Zeebrugge is contained in the contract.
