AI Collision Avoidance and Watchkeeping Assistance for Yachts

01

Why it matters

Without AI, watchkeeping gaps can lead to unplanned maneuvers, near-misses, false alarms, missed COLREGs breaches, and inconsistent bridge procedures during cruises and charters.

02

From design to safety

1. Design

   AI-assisted COLREGs planning

   During design, data models predict collision risk, define sensor interfaces, specify thresholds, and outline decision matrices for radar, AIS, cameras, and thermal sensors to support future certification and crew procedures. Detailed hazard maps, interface control documents, and fail-operational concepts are defined for formal class approval.

   • CCTV cameras
   • Bridge alarm panel

2. Build

   Systems integration and validation

   In build, sensor fusion hardware is installed, software modules map data streams, and sea trials certify response times, alarm logic, and failover behavior; system calibration includes radar cross-section verification, sensor alignment procedures, and redundancy testing with simulated targets.

3. Operation

   Real-time watchkeeping and routing

   During operation, the system processes live feeds, flags COLREGs conflicts, suggests safe course changes, and logs events for traceability and audit; it also maintains a watch checklist, supports phase-appropriate watch routines, and alerts the helmsman with step-by-step guidance.

4. Maintenance

   Sensor health and PMS integration

   Maintenance uses PMS to track calibration cycles, perform firmware updates, record fault trends, and schedule sensor replacements before degradation impacts alerts; scheduled drydock inspections verify system integrity, alignment, and navigator training completes with competency tests.

5. Safety

   Auditable safety and compliance

   Safety checks validate alarms, bridge procedures, and flag/state compliance with class and flag requirements; logs support audits and incident investigations, with periodic drills validating cross-department response times, regulatory alignment, and continuous improvements to watchstanding protocols.

Part by part

1. 1

   Radar

   Watch for

   Radar video noise, clutter, or misalignment indicating degraded performance.

   AI action

   Detect LO/HI radar targets and adjust alert priority in real time.

2. 2

   AIS transponder

   Watch for

   AIS data gaps or spoofed identifiers risking misidentification or false targets.

   AI action

   Flag inconsistent MMSI data and prompt collision risk assessment.

3. 3

   CCTV cameras

   Watch for

   Camera blind spots or fogging reducing scene clarity; lighting changes affect recognition.

   AI action

   Trigger multi-sensor cross-check and alert potential COLREGs breach.

4. 4

   Thermal camera

   Watch for

   Thermal image drift or obstruction affecting heat signatures of vessels.

   AI action

   Correlate thermal tracks with radar to confirm targets.

5. 5

   Bridge alarm panel

   Watch for

   Alarm thresholds not aligned with operating mode or wheelhouse procedures.

   AI action

   Adjust alert levels and issue crew guidance prompts.

6. 6

   Alarm siren

   Watch for

   False alarm or desensitization reducing response to real risk.

   AI action

   Train crew to acknowledge high-priority alarms and execute watch routine.

How to roll it out

1. Phase 1

   Phase 1

   Weeks 1 to 4 establish baseline alerts and sensor interfaces.

2. Phase 2

   Phase 2

   Weeks 5 to 8 refine COLREGs decision rules and alarm logic.

3. Phase 3

   Phase 3

   Weeks 9 to 12 validate in sea trials and on-vessel drills.

06

Where people stay in charge

• All decisions on maneuvering and legal compliance must be signed off by the captain or navigating officer.
• Alarms and advisories must be reviewed by the vessel’s Master and the safety officer before execution.
• Regulatory and class compliance must be checked by the yard’s surveyor or flag state inspector before deployment.
