A research team led by Cha Song Il, a section head at the Faculty of Shipbuilding and Ocean Engineering, has developed a course control system by turning electric propulsion and helm for arbitrarily controlling the course and turning radius of a ship.
The system consists of a propulsor, a reducer, a propulsion motor and a control board, a helm and a helm motor, and a helm control board so that the course of a ship can be controlled easily and arbitrarily in different situations and conditions.
A long ship has difficulty controlling its course and entry into and departure from a port on narrow and shallow waters.
The turning electric propulsor enables convenient entry into and departure from a port without recourse to a tow rope. The helm at the stern and the propeller at the bow guarantee safe navigation in complex waters and natural environments, thus reducing fuel consumption and navigation time.
They carried out speed control of a 17kW turning propulsion motor in conformity with its hydrodynamic characteristics to prevent overload and they changed the thrust according to the change in disturbance to raise the safety of a ship.
With such advantages, this system will find wide application to large cargo ships and passenger ships.
