Why it matters
Without it, unplanned haul-outs and overdue refits disrupt charters, cause scheduling clashes, raise warranty disputes, and complicate compliance with class surveys.
From design to safety
Design
AI informs capacity constraints
The system reads project backlog, dock availability, skill mix, lead times, vendor queues, and access permissions to outline feasible capacity, constraint flags, and alert thresholds for early planning.
- dock slots
- refit projects
- workforce
- schedules
Build
Optimize build sequencing
It ingests project briefs, material lead times, yard crew rosters, crane availability, and subcontractor calendars to produce a phased schedule with buffer recommendations and critical-path alerts.
- dock slots
- refit projects
- workforce
- schedules
Operation
Dynamic berth management
Ongoing data on arrivals, departures, weather, tide windows, and crane lanes is used to adjust raft allocations, service windows, and berth priorities in real time.
- dock slots
- workforce
- schedules
- refit projects
Maintenance
Prevent delays through forecasting
It analyzes historical downtime, equipment readiness, spare-part availability, and vendor lead times to pre-allocate maintenance bays and labour slots.

Safety
Regulatory and safety fit
The system flags non-compliance risks and ensures schedule milestones align with class surveys, flag state requirements, and safety checks, with sign-off by the safety officer.

Part by part
- 1
Main engine
- Watch for
- Unscheduled vibration, abnormal exhaust temperature rise, or fuel/oil leaks that could delay testing window.
- AI action
- Detect anomalies in vibration or temperature; trigger maintenance walkthrough and test run window adjustment.
- 2
Propulsion shaft
- Watch for
- Excessive vibration, misalignment signs, or bearing wear patterns during shaft alley checks.
- AI action
- Flag potential misalignment; schedule realignment and bearing inspection before next sea trial.
- 3
Generator set
- Watch for
- Low electrical output, fuel pressure fluctuation, or cooling fan anomalies impacting load balance.
- AI action
- Flag generator underperforming; trigger fuel system inspection and load-test plan.
- 4
Sea chest
- Watch for
- Corrosion signs, blockage from marine growth, or valve sticking observed in routine inspections.
- AI action
- Prompt cleaning/inspection and valve travel check; adjust pump sequence to maintain cooling flow.
- 5
Stern gear
- Watch for
- Wear or backlash in stern tube bearings, anchor and stern gear operation anomalies.
- AI action
- Schedule bearing inspection and stern gear clearance check; adjust alignment plan.
- 6
Fuel tank
- Watch for
- Fuel contamination or inconsistent level readings across tanks affecting inventory planning.
- AI action
- Trigger sampling and purification check; align fuel procurement to refit schedule.
Worked example
Catching a dock-slot conflict before a charter
Illustrative scenario with sample data.
A 38m explorer yacht requires a prune for hull inspection and refit slots during a peak season window. A late delivery of spares threatens the plan.
Signal in
slotForecast.date=2026-11-20; dockAvailability=limited; refitProjects=[HullInspection, PaintTouchup]; workforce=[TechnicianA, TechnicianB, PainterC]; weatherForecast=stable; materialLeadTimes=short; craneLaneAvailability=limited; seawaterTemp=15C; tideWindow=18:30-22:00.
System out
alert: slot conflict; action: re-sequence HullInspection to off-peak; notify project manager; adjust crane lane and workforce allocation; update procurement plan; add standby labour pool and alternate crane slot.
Human sign-off: Chief engineer reviews the alert and approves the re-sequenced plan with yard project manager.
How to roll it out
Phase 1
Weeks 1 to 4
Baseline data collection on dock slots, bookings, and workforce; establish KPIs and data interfaces; initiate integration with ERP and PMS modules.
Phase 2
Weeks 5 to 8
Develop forecasting models for occupancy, lead times, and risk buffers; pilot in one yard with limited projects; refine data schemas and alerts.
Phase 3
Weeks 9 to 12
Scale to multiple yards; fine-tune thresholds; implement automated alerts and schedule exports to ERP; prepare multi-yard dashboards for fleet managers.
Where people stay in charge
- All capacity decisions must be reviewed by a qualified yard project manager and the head of operations before execution.
- Safety compliance and class-facing milestones must be included in every schedule and approved by the yard’s safety officer.
- Contracts and subcontractor engagement must reflect any revised berth allocations and project sequencing to avoid penalties.
Questions owners and crews ask
How does AI slot planning help marinas manage peak season arrivals?
AI slot planning coordinates berth assignments, refit sequencing, and workforce shifts, improving visibility into dock availability and preventing clashes with other vessels or maintenance work. It also provides alerts for weather windows and crane lane usage to protect critical path timelines.
What data feeds power the capacity model?
The model consumes dock slot calendars, project backlog, crew rosters, material lead times, weather forecasts, vessel readiness records, crane schedules, and tide windows to predict capacity and risk.
Who approves changes to refit schedules caused by AI recommendations?
The yard project manager and operations head review and sign off, with class and flag compliance checked by the responsible parties; safety officer signs off on critical-path changes.
Can the system handle multi-yard fleet management?
Yes, it aggregates yard capacities, propagates constraints, and synchronizes schedules across sites to optimize overall fleet throughput; it exports consolidated dashboards for the fleet technical superintendent and financial controller.
