Research on hydrodynamic interaction indicates that if the speed of the ship near a bank is too high, the rudder may be less able to cope with the forces induced and control will be lost. The Nautical Institute highlights this in its latest Mars Report, in which an LPG carrier hit a barge being towed by a tugboat as a result of hydrodynamic forces.

According to AIS past track data, the vessel was obviously too fast on 9 knots and also going down the wind (4-5 bft., take a look at the exhaust from the stack) when entered the inner harbour considering the size and displacement. That speed was approximate 3 ship lengths to the pier and there was the on pier wind after the turn. Why the ship entered the port so fast will be the subject of the investigations to be awaited. Knowing South Korea procedures there will be no just marine...
