Dangerous phones arising from the waves during the oceanic route ship

Ocean routes are recommended for ships based on economic criteria. Under the influence of waves, during the cruise of the ship, dangerous phenomena are created, the intensity of which depends on the speed of the ship and its course in relation to the direction of the waves, the state of the sea, the size of the ship, the state of loading. Although weather services are known, waves parameters are not used to calculate the value of parameters that characterize dangerous phenomena. The article presents the most frequently analysed dangerous phenomena, how they are calculated, the criteria for their evaluation, and the results of calculations for the selected vessel.
