Why it matters
Without it, unplanned haul-outs, missed grease build-up hazards, delayed surveys, and safety incidents can arise due to manual checks and fragmented records.
From design to safety
Design
Design AI galley risk model
Define data streams from sensors, set threshold logic, and outline decision hierarchies for galley fire risk across all equipment. Include sensor redundancy, calibration routines, and owner-approved safety margins. Map interfaces to the vessel management system and archival compliance requirements for class surveys.

- wet chemical fire suppression system
Build
Install sensors and controls
Plan sensor placement, calibrate oil temperature and duct smoke sensors, and integrate with the vessel's central alarm and record system. Specify wiring looms, junction boxes, climate-controlled enclosures, and SPDT relays for safety interlocks. Verify cooling, EMI protection, and VDR logging compatibility.

Operation
Live monitoring and responses
Continuous data ingestion from sensors, risk scoring, and crew alerts with automatic shutoff and work order generation. Implement color-coded dashboards, audible alarms, data timestamps, and backfill capability for any sensor gaps. Define escalation path to captain and chief engineer.

Maintenance
Predictive maintenance scheduling
Track grease buildup trends, duct cleaning cycles, and chemical system service windows to optimize PMS and inspections. Generate monthly reports, track service vendors, and link to inventory for replacement parts.

Safety
Regulatory safe-guard enforcement
Maintain auditable logs, ensure class and flag state sign-offs, and enforce wet chemical service intervals for safety compliance. Prepare for drydock yard inspections with printed safety matrices and test records.

Worked example
Catching a leak in galley oil line before a charter
Illustrative scenario with sample data.
A 55m motor yacht approaches drydock; pre-charter survey flags rising duct smoke index and fryer oil temperature drift.
Signal in
fryerOilTemp=205C, ductSmokeIndex=0.75, greaseBuild=35%, suppressionPressure=3.2bar, hotWorkActive=false, lastService=18d
System out
Risk score rising; alert raised to chief engineer; maintenance task created for duct cleaning and wet chemical system check; watch for impending grease fire hazard.
Human sign-off: Chief engineer reviews the alert, confirms sensor validity, approves maintenance orders, and briefs the captain for crew readiness.
How to roll it out
Phase 1
Weeks 1 to 2
Baseline data capture across galley systems and sensor calibration checks.
Phase 2
Weeks 3 to 6
Pilot integration into the shipboard alarm system and maintenance planning module.
Phase 3
Weeks 7 to 10
Full operational rollout with crew training and safety documentation updates.
Where people stay in charge
- Only a qualified chief engineer or ship's safety officer may approve threshold changes or overrides that affect fire protections.
- All automated actions must be auditable with time-stamped confirmations and ready for class survey verification.
- Class and flag state sign-off is required for any override of emergency procedures or interlock behavior during critical events.
Questions owners and crews ask
What triggers an AI alert in the galley fire monitoring system?
An AI alert triggers when sensor data crosses predefined thresholds for oil temperature, duct smoke, and grease build-up, prompting crew action and maintenance work orders.
Who signs off on critical alerts and maintenance actions?
The chief engineer signs off most maintenance actions, with class and flag state approval required for safety-critical responses and regulatory compliance.
How does this integrate with class surveys?
All monitored data and maintenance events are logged for audit, enabling trend analysis during class surveys and ensuring regulatory readiness.
What records are kept for safety investigations?
Sensor histories, service records, safety actions, and crew confirmations are stored in the vessel's safety management system for incident review.
