Engine performance monitoring involves tracking engine speed (RPM), fuel consumption, oil pressure and temperature, coolant temperature, exhaust gas temperature, and turbocharger performance to optimize efficiency, reduce emissions, and prevent damage.
Data analysis and alerts are generated for abnormal engine behavior, performance degradation, and potential faults or failures.

Auxiliary Power Units (APUs) provide a secondary power source for propulsion and hotel loads, reducing main engine operating hours and improving fuel efficiency.
Types of APUs include diesel generators, gas turbines, and electric motors.
APUs perform functions such as power generation, air conditioning and ventilation, hydraulic and pneumatic systems, and emergency power supply.

Navigation and control systems ensure safe and efficient vessel operation through the use of GPS and navigation sensors, autopilot and steering systems, thrust control and propulsion systems, and alarm and monitoring systems.
Key functions include route planning and optimization, collision avoidance and warning, vessel stabilization and control, and integration with propulsion and steering systems.

Fuel management systems optimize fuel consumption and reduce emissions through the use of fuel flow meters and sensors, fuel consumption monitoring and analysis, fuel tank level and pressure monitoring, and fuel pump and valve control.
Real-time fuel consumption monitoring, fuel efficiency optimization, fuel tank management and inventory control, and alerts for fuel leaks or system faults are key functions of fuel management systems.
