VLM output
Aerial drone footage pans over a container terminal where two general cargo ships are moored alongside the quay, one white-superstructure vessel in the foreground and a green-hulled vessel further along the berth. Quay cranes and a mobile harbour crane work the ships while trucks, reach stackers and stacked containers occupy the yard; the water is calm and both vessels remain stationary at their berths.

Customer challenges
The berthing moment has no live measurement; distance and angle rest heavily on the pilot's experience
AIS and VTS data arrive with latency and cannot reflect precise distance or relative speed
Abnormal conditions rely on VTS staff watching screens around the clock, inviting fatigue and oversight
Personnel safety between ship and quay and in the snap-back zone depends on verbal reminders on site
No measurable, replayable safety baseline exists, so incidents cannot be reviewed nor pre-empted
Visibility falls at night and in sea fog or strong wind — monitoring is weakest when risk is highest
Customer benefits
24x7 AI-driven proactive berthing safety alerts
Pilots and crews receive objective distance, speed and angle data with voice prompts
Collision risk to quay and neighbouring vessels flagged 30+ seconds ahead of the human eye
Man-overboard and mooring-line snap-back incidents watched continuously by AI
Every berthing and unberthing leaves a measurable, replayable record
Mounted on existing light poles, with no marine works required
Key features
Real-to-Sim Vessel Tracking
Multi-focal cameras on quay light poles cover the full length of the quay, track vessel position, speed and angle across cameras in real time, fuse AIS, vessel dynamics and met-ocean data, and use thermal dual-spectrum imaging usable at night and in sea fog.
VLM Hazard Alerts with Signal-Light Grading
Alerts on excess approach speed, steep approach angle and ship-to-quay distance breach, insufficient clearance to vessels fore and aft while moored, excessive lateral drift and bow or stern swing on departure, and personnel not clear of the danger zone, with proactive VHF voice warning.
VTS Integration and Evidence
Projects events in real time with virtual signage, displays them together with VTS and AIS, and retains full imagery and tracks with de-identification.
VLM Hazard Alerts with Three-Tier Warning
Grades VLM hazard alerts into three tiers of warning.
Digital Twin, VTS Integration and Evidence
Projects events into the digital twin, integrates with VTS and AIS, and retains imagery and tracks as evidence.
