2. Core Product Functions

• Real-Time Closed-Loop Propulsion & DP Control Executes high-speed dynamic positioning algorithms, collects real-time data from thrusters, position reference systems and Bergen marine engines to automatically adjust thrust for vessel position holding, critical for offshore operation safety.
• Vessel Power Management System Coordination Monitors generator load, bus voltage and frequency, implements load shedding, parallel generator synchronization and fault power isolation to prevent blackout on marine vessels.
• Multi-Bus Redundant Data Gateway Bidirectional data conversion between Ethernet control network, CAN bus engine interfaces and RS485 field sensors; dual Ethernet redundancy ensures uninterrupted communication under single network failure.
• On-Board Engine Health Monitoring (EHM) Continuously processes temperature, pressure, vibration and fuel consumption sensor signals from main engines, generates trend logs and early fault pre-alarms to reduce unplanned downtime.
• Hot-Swap & Offline Configuration Storage Supports live module replacement without full system shutdown; built-in flash memory stores complete control logic, DP parameters and alarm history for quick restoration during maintenance.
• Full Built-In Diagnostic & Alarm System Multi-status LED indicators and internal fault log recorder to track communication loss, power anomaly, CPU overload and sensor signal deviation for rapid on-site troubleshooting.
• Marine Safety Interlock Logic Execution Runs safety interlock routines for propulsion shutdown, emergency stop, fire suppression and bilge pump control, complying with international marine safety regulations.
• System Data Logging & Remote Supervisory Transmission Stores long-term vessel operation data, transmits real-time status to bridge HMI and shore remote monitoring platforms via Ethernet.

3. Typical Application Scenarios
