Bridge Collision Prevention

Proactive vessel approach monitoring and alarms to prevent bridge strikes and ensure navigational safety.

Thách thức của ngành

Late awareness of fast-moving vessels
Poor visibility in fog, heavy rain and at night
Manual watchkeeping fatigue and inconsistent response

Safety Context

Bridge strikes cause severe structural damage and traffic disruption. Early detection and trajectory estimation are key to preventing incidents and mitigating risk.

Prevention Workflow

Radar monitors approach lanes and exclusion zones around piers.
If CPA/TCPA risk rises, the system escalates alarms (visual/audible).
PTZ cameras auto-cue; warnings broadcast via VHF or sirens.
Incident is logged with tracks and video for review and compliance.

Integration & Compliance

Interfaces with traffic control centers and maritime authorities
Supports audit trails and reporting for safety management systems
