Gdynia Harbour Second largest in Poland One of the largest in the Baltic Sea 3
Gdynia Harbour In Gdansk Bay No tides Relatively low currents Occasional strong and irregular winds Wind driven surface currents Gdansk Bay 4
Strong Wind pushed Ferry onto Breakwater
Winter conditions with occasional ice
Topography adapted model used for simulating and predicting waves, water level and currents. Big coarse grid for the western part of Gdansk Bay Main driving force of model is wind.
Small refined grid for Gdynia harbour Big coarse grid for the western part of Gdansk Bay

Conclusions Auckland, September 2015 Ferry has been pushed onto brake water at the Gdynia harbour entrance For safer entry important to know and compensate for local conditions Model assimilate real-time data to predict waves, water level and currents Model was calibrated/verified with more than one year of high quality field data Scaled ferry specific tow tank and wind tunnel tests predicts effects on ship Data is transmitted every 10 sec. with recommendations on safe approach Model adapted for cleaning of chemical spill, if occurring Zmiana kursu uwzględniający istniejący prąd
