Why it matters
Without AI, quotes drift through scope changes, missing materials, untracked labour, and margin erosion, leading to delays, disputes, and warranty contention.
From design to safety
Design
AI assists scope definition and risk review
It reads initial client brief, regulations, PMS constraints, and equipment conditions to draft a baseline bill of quantities, risk register, and a cost envelope for contingency and early procurement decisions.

Build
Estimating across procurement, labour, and inventory
It integrates vendor catalogs, lead times, shop capacity, labour rates, and make/buy decisions to produce a synchronized work list and a cost plan with supplier warranties.

Operation
Progress tracking, replanning, and approvals
It monitors live progress against plan, flags deviations, re-sequences tasks, and issues interim change orders to protect schedule and client confidence.

Maintenance
Lifecycle cost forecasting and PMS alignment
It analyzes usage patterns, PMS tasks, part wear data, maintenance history, and warranty terms to forecast replenishments and phased replacements with budget alignment.

Part by part
- 1
hull
- Watch for
- risk of structural delamination or bilge moisture affecting fitment costs
- AI action
- flag anomaly; trigger scope tightening, require additional non-destructive testing before quoting, and lock in contingency for hull work order changes.
- 2
propulsion
- Watch for
- propeller wear pattern or shaft lubrication inconsistencies impacting install time
- AI action
- adjust labour hours; propose alternative propeller or shaft options; recalculate rigging load impacts and supplier lead times.
- 3
engine
- Watch for
- main engine cooling and fuel system integrity affecting PM and spares
- AI action
- recommend PM scope; surface risk and order critical spares; flag potential warranty coverage limitations.
- 4
generator
- Watch for
- generator set readiness and exhaust system condition
- AI action
- quote genset refurbishment vs replacement; adjust lead times; validate spares availability and service window.
- 5
electrical
- Watch for
- switchboard faults and wiring loom aging influencing panel build
- AI action
- reconcile electrical bill of materials with labour rates; flag non-conforming items; push for updated certificates and test plans.
- 6
safety
- Watch for
- lifesaving appliance compliance gaps or muster equipment timing
- AI action
- insert safety margin in contingency; schedule inspection tests; align with class and insurer inspection windows.
Worked example
Catching a scope drift before a charter
Illustrative scenario with sample data.
A 40m displacement yacht undergoing refit requires hull repaint, new stern gear, and upgraded electrical distribution after hull inspection reveals corroded stern gear attachment points.
Signal in
brief: hull repaint, stern gear upgrade, electrical distribution revamp; data: hull survey 3A, stern gear wear 65%, PMS last 18 months, lead times 12 weeks, labour rates 120/h, material costs escalate 8%
System out
quote issued: hull repaint 320k, stern gear replacement 180k, electrical revamp 260k; total estimate 760k; contingency 60k; schedule 16 weeks; risk register items flagged.
Human sign-off: Yard project manager reviews and signs off; client approves final quote, with insurer and class guidance.
How to roll it out
Phase 1
Weeks 1 to 4
Baseline data capture, vendor catalogs, and standard quoting templates enabled; initial risk register populated.
Phase 2
Weeks 5 to 10
Integrated cost model with live shop capacity, labour pools, material lead times, and procurement milestones defined.
Phase 3
Weeks 11 to 20
Final quotes issued, change control process established, and owner approvals obtained with sign-off from insurer and class.
Where people stay in charge
- All quotes must be reviewed by a qualified estimator and project manager before client submission.
- All material substitutions require class and flag state approval and supplier certification.
- Sign-offs from yard, owner, and insurer must be documented for each change order.
Questions owners and crews ask
What affects refit costs the most?
The scope definition, material lead times, and labour availability drive the largest changes to quotes, with risk of scope creep requiring formal change orders.
How is reliability ensured in estimates?
Estimates rely on historical shop data, PMS schedules, and validated supplier catalogs; every assumption is auditable and traceable in the final quote.
Who approves changes during a refit?
The yard project manager signs changes; the captain or owner approves with the insurer and class under guidance from the naval architect.
How is margin protected in a refit quote?
Contingencies, procurement discounts, and accurate labour rates are included; any risk-based variance is flagged for owner approval before purchase orders.
