VLM output
A gantry crane lifts a large steel hull block by spreader beam over an outfitting quay at a shipyard, while a worker in a hi-vis vest and white hard hat walks near stacked steel plates on the wharf. Over the four frames the camera pans right along the quay, revealing a partially assembled hull section, additional cranes, and a grey naval vessel moored at the edge with visible mooring lines.

Customer challenges
Work is spread across slipways, block areas, paint shops, quays and waters, beyond what safety staff can watch at all times
Work at height, lifting, hot work and confined spaces are shipbuilding's highest risks, and violations happen in an instant
Quay edges and yard waters carry a risk of falling in, and are almost unwatched at night and off-peak
A high share of contractors and temporary workers means uneven training and compliance
Sight lines inside blocks and compartments are obstructed and hard to cover with conventional CCTV
Violations are recorded only during incidents or audits, leaving no day-to-day data
In an emergency there is no immediate count of who is on site and in which area
Managing yard and waters as two systems means events cannot be judged in one view
A single serious injury brings work stoppage, fines and delivery delay
Customer benefits
High-risk work moves from spot checks to continuous auditing
Violations alert as they happen, not in the incident report afterwards
Yard and waterfront managed in one system and one scene
Quay fall risk is covered at night and off-peak as well
Contractor safety management gains objective, quantified data
An immediate count of who is on site and where during an emergency
Lower load on safety patrol staff
A traceable digital safety record supporting audit and insurance
Mostly existing cameras, with added positions only for blind spots and waters, keeping entry cost low
Key features
High-Risk Work Compliance
Detects work at height without a harness or guardrail, personnel entering the area under a suspended load, missing fire watch or extinguisher for hot work, lone entry into confined spaces with entry and exit reconciliation, and welding mask, gloves and protective clothing compliance.
Waterfront & Berth Safety
Detects falls from the quay edge, work over water without a life jacket, personnel inside the danger zone during mooring, exclusion zone breaches for block launching and lifts over water, and monitors workboat and tug berthing operations.
PPE, Access & Contractor Compliance
Recognizes hard hat, high-visibility vest and safety footwear, records personnel and vehicle entry and exit, matches contractor personnel to authorised work areas, detects unauthorised entry into slipways, paint areas, hazardous stores and quay work zones, and reconciles on-site headcount for emergency evacuation.
Event-to-Twin Mapping
Locates violations and falls on the shipyard digital twin with yard and waterfront in one scene, using zoned rules for lift radii, hot work areas, confined space entries and quay exclusion lines.
Incident Management
Pushes real-time alerts to the safety office and area supervisors on mobile devices, retains footage automatically with statistical reporting, manages yards centrally with AI violation classification, and answers natural-language queries.
