The Typical Block Diagram for a CCTV system on board FPSO Vessel
Location: Installed in various hazardous and non-hazardous areas such as the deck, engine room, living quarters, and topside process areas.
Types: Fixed cameras, PTZ (Pan-Tilt-Zoom) cameras, thermal cameras (for night vision or low visibility areas), and specialty cameras (e.g., for flare stack monitoring).
Explosion-Proof: To meet offshore safety standards (ATEX, IECEx) for hazardous zones.
2. Camera Enclosures
Material: Stainless steel, ensuring corrosion resistance.
Certifications: Designed to prevent ignition sources in hazardous areas.
3. Camera Power Supply Units (PSU)
Function: Provides power to the cameras, typically through Power over Ethernet (PoE) or separate power supplies.
Redundancy: Often integrated with UPS (Uninterruptible Power Supply) for critical operation.
4. Network Switches (Ethernet Switches)
Location: Distributed in control rooms or communication cabinets across the FPSO.
Function: Switches aggregate camera data for transmission to the control center. In some cases, they are PoE switches that power the cameras.
Industrial-Grade: Designed to withstand harsh marine environments (humidity, vibration, and temperature).
5. Fiber Optic Backbone
Purpose: High-speed data transmission from remote locations on the vessel to the central control room.
Advantages: Fiber optics ensure data integrity and long-distance transmission without signal degradation.
6. Network Video Recorder (NVR)
Function: Receives video streams from the cameras over the IP network and records them for storage and future playback.
Storage: High-capacity storage drives, with RAID configurations for redundancy.
Playback/Export: Allows operators to review footage or export data for investigations.
7. Control Room / Monitoring Station
Main Component: Central station where operators monitor live video feeds and recorded footage.
Monitors: Multi-screen setups for viewing several camera feeds simultaneously.
Video Management Software (VMS): Used to control camera functions like PTZ, video recording, and analysis. It also provides features like motion detection, alarms, and event logging.
Redundant Systems: Backup servers and data centers for continuous operation in case of hardware failure.
8. Explosion-Proof Joystick Controllers (for PTZ cameras)
Purpose: Allows operators to control the movement of PTZ cameras remotely for detailed area inspection.
9. Satellite / Remote Communication (Optional)
Purpose: Enables remote viewing and control from an onshore control center through satellite or radio links. This is often used for remote support and monitoring from a distant operations center.
10. Alarm Integration
Integration: The CCTV system is often integrated with the FPSO’s overall safety systems, such as PAGA (Public Address and General Alarm) systems, fire detection, and access control systems.
Event Triggers: Cameras are programmed to record or alert when alarms are triggered by other systems.
