Why it matters
Without this, wear patterns and water ingress go unnoticed, leading to unplanned drydock, delayed charters, costly repairs, and safety issues from deck ply delamination or fastener failure.
From design to safety
Design
AI-informed deck health design
The design reads moisture sensors, thickness gauges, citric acid test results, and caulking histories to define acceptable ranges and replacement triggers for teak planks, seams, and fasteners. It also maps UV exposure, wind-driven rain zones, and seasonal humidity shifts to shape material choices and seam configurations.

- caulking seams
- deck thickness gauge
- screws and plugs
Build
Quality planning and inspection
During build, data from thickness tests, fastener torque, moisture probes, and non-destructive testing of core wood set baselines and guide sealing strategies and source selection for deck components. It logs batch numbers, epoxy resin compatibility, and waterproofing layer compatibility to Class and flag requirements.

Operation
Ongoing monitoring and prognosis
In service, continuous readings from moisture sensors, water ingress monitors, UV sensors, and corrosion indicators feed AI to forecast deck life and plan replacements. It continuously compares expected plank life to actual wear and flags creeping moisture at seam intersections.

Maintenance
Replacement planning and PMS
AI aligns PMS with actual wear, prioritizes plank replacement, resealing, fastener refreshing, and thickness restoration based on risk thresholds and schedule windows. It creates a work package with drydock slots, supply orders, and QA checklists for each panel group.

Safety
Safety and compliance checks
The system flags high-risk areas for crew access, ensures record-keeping for flag state surveys, and supports class notation submissions for deck work. It cross-verifies torque, sealant ages, and plank thickness against allowed limits per class rules.

Part by part
- 1
teak planks
- Watch for
- checking for delamination, cupping, or hollow regions beneath surface
- AI action
- trigger replacement window when thickness loss exceeds threshold or moisture spike detected, and reference last drydock records for batch consistency
- 2
caulking seams
- Watch for
- loss of sealant elasticity, cracking, or water seepage at seams
- AI action
- flag sealant degradation and schedule resealing or re-caulk in upcoming drydock; log sealant type, shore supply compatibility, and cure times
- 3
deck thickness gauge
- Watch for
- measured plank thickness approaching minimum allowed
- AI action
- issue replacement urgency for affected plank groups and re-measure adjacent areas, compare to original thickness maps from build phase
- 4
screws and plugs
- Watch for
- loosening, corrosion, or hidden backing plate movement
- AI action
- recommend retorquing, corrosion treatment, or full screw/plug replacement as needed, record torque history and batch numbers
- 5
water ingress monitor
- Watch for
- rising moisture in core or under decks
- AI action
- generate moisture map and preventive maintenance tasks for suspected ingress zones; trigger localized inspection teams during sea states under 6 Bft
- 6
synthetic deck alternative
- Watch for
- wear, UV degradation, coating mismatch or delamination
- AI action
- assess replacement with synthetic deck section and update life-cycle cost model; reference Sun exposure index and maintenance cycle differences
Worked example
Replacing a teak panel before a charter
Illustrative scenario with sample data.
In late autumn, AI detects moisture accumulation and early delamination in a panel cluster near the sea chest, with UV degradation on adjacent planks.
Signal in
moisturePercent: 16, thicknessMM: 7.9, sealantState: aged, fastenerTorque: 18 Nm, seaTrial: nominal, panelID: P-14, location: Starboard Aft Deck
System out
Alert: panel P-14 moisture spike with signs of sealant aging. Work order: reseal joints, replace affected planks in Panel 14, schedule drydock window 18 days before next charter, update deck records.
Human sign-off: Chief engineer approves work order; captain signs voyage schedule after confirming no high-risk crew access zones during charter
How to roll it out
Phase 1
Weeks 1 to 4
Baseline data collection from all sensors and manual measurements begins to establish reference deck health across all decks and panels.
Phase 2
Weeks 5 to 12
AI model calibrates against observed wear, sets escalation thresholds, and links to PMS modules; integrate with yard prep for refit window.
Phase 3
Weeks 13 onward
Integrated planning with yard and flag requirements; automated triggers for drydock, replacement windows, and archive of all deck work records.
Where people stay in charge
- Decisions on replacement timing must be approved by a qualified naval architect or class society surveyor.
- All data used for critical safety decisions must be reviewed by the captain and chief engineer before execution.
- Final compliance and record entries must be signed by the flag state inspector or authorized class representative.
Questions owners and crews ask
What signals indicate teak deck needs replacement soon?
The AI flags reduced thickness beyond threshold, moisture spikes persisting across panels, and recurring fastener issues, triggering a work plan reviewed by the chief engineer and yard; it also notes sealant aging and panel delamination risks.
How often are deck readings updated?
Sensors collect readings continuously, with a daily aggregation and weekly summaries reviewed by the captain and naval architect during surveys; maintenance plans reference the latest moisture maps and thickness charts.
Can we replace only parts of the deck?
Yes, the system can propose staged replacements by panel or plank group, balancing operational schedule with safety and class requirements; it records partial replacements against full deck life-cycle plans.
What records are created for charter compliance?
Moisture maps, thickness data, sealant logs, and replacement history are compiled into the deck maintenance dossier for inspection and insurance review; it includes torque histories, panel IDs, and drydock certificates.
