Description

s/s "HOKUTO MARU", a training ship of Japanese Government, was converted to automatic operation of a main turbine, boilers and other machineries by Kawasaki Dockyard in 1966. Main conversion works are on the followings; a) Main turbine remote control system including program control, b) Automatic control system of main turbine warming, stand-by, and stop sequence operations, c) New installation of automatic combustion control of boilers, automatic sequence operation of soot blowers and new installation of atuo-burners, and d) Scanning monitor and logger. Nowadays we see a lot of newly built ships with automatic control system, however up to now grand conversion works to automatic operation of existing ships have been seldom carried out. As its reasons we can easily recognize some obstructions and problems; namely obstructions against modifications of existing machineries and pipes, problems of spaces in engine room, and specially big problems of cost and period. At our conversion works, we were actually confronted with many problems. These problems and main points of the conversion will be reported briefly.
