A vessel had reported steering failure at sea and was boarded by port state control upon arrival. The steering gear was inspected without any findings and the vessel was allowed to proceed. The class was not informed. Whilst sailing half ahead on a river, the rudder suddenly blocked in a position nearly hard to starboard. The vessel touched the riverbank and stopped. All parts of the steering gear (machinery and bridge) were inspected by the crew and found in order. The captain and the pilot decided to continue the voyage, however, the problem reoccurred and the vessel ran aground again!
