Refits Run Over When the Drawings Don’t Match.
A survey-grade capture of the vessel before refit begins gives every discipline — naval architecture, mechanical, electrical, fit-out — accurate as-built data to design from. Less time in dock. Fewer site surprises. Scopes that hold.

Why Refits Overrun
Most refit overruns have the same root cause — engineering that began on drawings no longer matching the vessel. The GA says one dimension; the vessel is another. Modifications from years ago were never recorded.
What That Costs
Each discrepancy costs time — and dry-dock time is the most expensive time a vessel can spend out of service. Fabrication re-done, installation adapted, the programme slips, day rates accumulate.
The Survey-First Fix
A refit survey eliminates those surprises before they happen. Survey-grade 3D scanning turns the vessel into an accurate, measurable digital model in a single mobilisation. Every discipline works from the same accurate baseline.
The Whole Vessel, or the Zones That Matter.
Hull Form & Envelope
External hull geometry captured precisely — form, waterline, freeboard, transom. Feeds stability recalculation, structural assessment and any work that touches the hull envelope.
Machinery & Engine Spaces
Engine room, generator spaces, auxiliary machinery — equipment positions, clearances, overhead heights, pipe and cable routing. The foundation for any mechanical or electrical refit scope.
Structural Members & Framing
Frames, girders, longitudinals, bulkheads and decks — positioned as they are, not as originally drawn. Identifies structural modifications since build and captures the actual constraint envelope.
Accommodation & Internal Spaces
Deckhead heights, internal partitioning, furniture and fitting positions, HVAC and ventilation routing. For passenger vessel or superyacht refits, often the most value-dense part of the survey.
Deck Arrangements & Topside
Working deck, wheelhouse, mast and aerial positions, deck fittings, crane and winch envelopes — documented as installed, not as originally specified.
Systems Interfaces & Connection Points
Key connection points, manifolds, distribution panels and system interfaces captured spatially — giving the engineering team accurate integration context before design begins.
Capture Once. Every Discipline Works From It.
Pre-Refit Survey
Survey-grade 3D capture of the vessel before any work begins — in dock, alongside or afloat. The full as-built record delivered before the first design meeting.
Engineering & Design
Naval architects, mechanical engineers and electrical designers work directly from the captured geometry — GA arrangement, stability calculations, system design, fit-out layout. Accurate from the start.
Yard Coordination
The survey data is available to the refit yard before the vessel arrives. Fabrication can be pre-sized, installation sequences planned, and clashes identified on the model rather than on the vessel.
Post-Refit Record
A follow-on survey after refit completion updates the digital twin to the as-refitted state — giving the owner an accurate record after the work, ready for the next programme.
