Abstract
This paper reports on a CPP Control Back-up System utilizing a CRT, which has been newly developed by NKK and installed on the NKK's new energy saving ships equipped with PC engines and controllable pitch propellers (CPP) .
This system consists of a CPP control system featuring automatic load control, constant ship speed control and constant SHP control as well as a data display system utilizing a color graphic CRT which displays the characteristics of the main engine and the CPP, the operating point of the main engine and various actual operating data of the main propulsion system.
This system makes it easy to perform fine aiming of such operation targets as energy savings, high operating rates, low maintenance costs, etc.
