Why it matters
Without AI, disjointed data and slow pattern selection lead to misdirected efforts, delayed alerts, and gaps in surface signals or coastguard coordination, risking diver safety and insurance coverage.
From design to safety
Design
AI-driven search design
The system reads last known position, current drift, air and wind data, surface conditions, visibility, water temperature, dive roster constraints, abort thresholds, and EN 12021 air quality test results to propose consolidated search corridors, escalation steps, and contingency routes, including predefined sweeps and hold points.

Build
Data flow and integration
Integrates GPS, drift models, weather feeds, rescue signals, incident file schema with fields incidentID, time stamps, GPS, driftModelVersion, and access controls; coalesces coastguard contact protocols into a shared incident file for rapid activation and traceable audit trails.

Operation
Real-time search orchestration
Reads live position feeds, drift rates, wind and visibility updates, SOS messages, and coastguard status to generate search polygons, prioritize sectors, schedule surface signals with cadence targets, and update incident log with latency under 2 seconds.

Safety
Auditable incident procedures
Ensures the AI’s decisions, signals, and coastguard calls are documented with sign-offs from the diving supervisor, safety officer, and senior operations manager; maintains standardized incident pack templates and PDF deliverables for audits.

Part by part
- 1
GPS receiver
- Watch for
- Drift data mismatch or loss of satellite lock during operations; repeated anomalies or clock drift.
- AI action
- Flag GPS anomaly; pause AI guidance; request manual verification; log anomaly in incident file.
- 2
VHF radio
- Watch for
- Interference or failure to establish contact with coastguard or vessels; channel hopping detected.
- AI action
- Prompt operator to retry calls; switch to alternate channel or satellite messenger; log communication failure.
- 3
Surface Marker Buoy with spool
- Watch for
- SMB not deploying on time or reel wear showing snag risk; line stretch.
- AI action
- Suggest deploy now; log deployment time, wind conditions, deployment method, and any snags.
- 4
Emergency beacon
- Watch for
- Battery low or beacon silent during test; failure to transmit.
- AI action
- Trigger pre-emptive check; prepare manual signal plan; record test result.
- 5
Diver recall timer console
- Watch for
- Timer drift or miscalibration affecting signal timing; alert threshold breached.
- AI action
- Recalibrate timer; alert safety officer of timing deviation; freeze non-critical alerts.
- 6
Coastguard liaison logbook
- Watch for
- Contacts missing or outdated on incident escalation paths; missing permission records.
- AI action
- Prompt update; auto-create contact packet; append escalation path and last verified date.
Worked example
Catching a drifted diver in poor light
Illustrative scenario with sample data.
A diver loses contact during a drift at a known site, current shifts, and visibility drops; AI plans search corridors, triggers surface signals, and prompts coastguard alert with a documented incident pack.
Signal in
lastKnownPosition=Site A; driftRate=1.2 kt S; wind=North 15 kt; airRemaining=1800 psi; roster=2 instructors, 3 divers; lastContactTime=14:32; surfaceSignalCapable=true; coastguardAvailable=false; visibility=2 m; waterTemp=22C; diveSite=Site A; gpsQuality=good; sosStatus=none
System out
searchPolygons=[Polygon1,Polygon2]; SMBdeployed=true; coastguardCall=initiated; incidentLog.update(time=14:34, action=SearchPlan, responsible=DiveSafetyOfficer); urgentFlag=true; surfaceSignalManualOverride=true; driftModelVersion=3.4
Human sign-off: Diving supervisor reviews AI plan, confirms coastguard notification, authorizes deployment sequence, and signs off on incident pack with safety officer; executive review queued.
How to roll it out
Phase 1
Weeks 1 to 2
Baseline data feeds and emergency fixtures tested; operator trains on AI prompts, manual override, and logging requirements.
Phase 2
Weeks 3 to 6
Live drills with coastguard liaison; incident log templates completed, validated, and pre-filled with site-specific patterns.
Phase 3
Weeks 7 to 8
Full operational handoff; review and sign-off by course director and safety officer; final audit pack stored.
Where people stay in charge
- Decisions affecting diver safety must be validated by the dive safety officer before action is executed; all coastguard calls require supervisor approval.
- All coastguard contact and escalation steps require approval by the senior supervising instructor or operations manager; logs must be immutable for audit.
- Critical data changes, like drift model updates or GPS feed changes, require documented authentication and version control.
Questions owners and crews ask
What data signals does the AI use to start a lost diver search pattern?
The AI uses last known position, current drift, wind, water conditions, air supply status, dive roster constraints, GPS quality, and escalation steps to generate initial search patterns and trigger procedures.
Who signs off an AI-directed search plan during an incident?
The diving supervisor or safety officer signs off the plan, with final authority resting with the dive operations manager; the course director may review post-incident.
How are coastguard calls integrated into the system?
The system auto-generates a coastguard call packet, prompts the operator to initiate contact, records time and channel used, and attaches to the incident file for audit.
What maintenance ensures AI reliability in emergencies?
Regular sensor health checks, log integrity validation, drift model updates, test signals, and verified functionality of emergency communications assets; ensure seven-year retention.
