Control system upgrade on a class of ships for a major international cruise line

Project Overview
Pneumatic master/slave loadsharing system caused problems during operation and it was costly and difficult to find spare parts for the out-dated control system.  828 control system with HMI touch screen supervisory unit replaced obsolete PGA with load divider governors.

Control System Components

• Woodward 828 Digital Control with Marine Load Sharing Software
• Woodward PG-Actuator
• MPU’s (Magnetic Pick-Up’s) for speed sensing
• HMI (Human Machine Interface) to monitor data

Control/Customer Benefits
Better reliability by eliminating air-leaks and calibration issues, more reliable clutching - automatic clutch in sequence, improved loadsharing and engine overload protection.  The customer realized fuel savings as a result of clutching engine in and out at sea without reducing propeller speed and easier troubleshooting using the HMI.
