Holland America Line Ship Upgrade


GCS custom - designed a n engine - generator control and monitoring system for two diesel - electric S - Class cruise ships. The vessel s utilize five Sulzer ZA40 engines for power generation, providing a total capacity of 34 MW at full load. T he nominal engine speed is 514 RPM at 60 Hz.

  • S-Class Diesel Electric Cruise Ship: Overall Length: 719 ft Beam Length: 101 ft Passenger Capacity: 1258 Crew Members: 580 Gross Tonnage: 55,575 Maximum Speed: 22 Knots
  • Prime Power Generation
  • (2x) Sulzer 12ZAV40S Diesel Engine - Generators Each 8 000 kW, 4160V @ 514 RPM
  • ( 3 x) Sulzer 8ZAL40 Diesel Engine - Generators Each 6 000 kW, 6600 V @ 514 RPM
  • Woodward 733 Integrated Control Package for s peed c ontrol, load control, loa d - sharing, monitoring , and overspeed detection
  • Woodward EGB Actuator Hydraulic A ctuator with M echanical Ball - H ead B ackup
  • Ethernet Network Inter - control network including Ethernet switches, and Modbus converters.
  • HMI / SCADA System Touch - screen terminal in the engine control room for monitoring, alarming, trending , and event logging.

The control system features custom application software integrating the engine speed control , load control , and load - sharing functionality into a single engine - level uni t. The controls communicate to each other via a redu ndant CAN communication network. In the event of a primary CAN communication network failure, the control system alarms and automatically switches to the second network in a bump - less fashion.

The 733 controls were chosen to repl ace the obsolete Woodward 721 controls originally on the vessel. This choice allowed the addition of feat ures that were previously un available including an adaptive start - fuel limiter to reduce the amoun t of smoke during engine start ing . This is an important feature for cruise vessels that sail in Alaska and other areas where fines can be imposed due to excessive smoke during start - up.

Central monitoring and control is performed via a custom, GCS designed HMI system featuring a 17“ color touch - screen terminal in the engine control room. The HMI gathers data from all five 733 controls and provides the operator with an interface for system cont rol, monitoring , trending, alarming and event logging.
