Capture the as-built.
Most marine projects start from drawings that no longer match the asset. Isca starts by capturing what’s actually there — survey-grade 3D laser scanning that turns a vessel or structure into an accurate, measurable digital twin. The trusted starting point for every decision that follows.

Survey-Grade Capture, End to End.
We deliver survey and digital twin services across vessels, structures and sites — from the capture on board to the processed model your engineering is built on.
3D Laser Scanning
High-density survey-grade scanning — under scaffold, in confined spaces, or on the water.
Point Cloud Processing
Raw scans registered, cleaned and aligned into a single dimensionally reliable point cloud at a known tolerance.
Digital Twin Capture
An accurate 3D model of the captured spaces — suitable for clash detection, routing and downstream design.
Confined & On-Water Survey
Capture in machinery spaces, tanks and afloat, where conventional measurement is slow and error-prone.
Reverse Engineering
Deriving usable geometry from the as-built where original drawings are missing or out of date.
As-Built Models
Verified dimensional models and extracts that replace unreliable legacy drawings for the scope of work.
What Vessels and Operators Come to Us For.
The capabilities above are how we survey. These are the situations that actually bring owners and operators to us — each with its own dedicated page.
Vessel Information Management
An as-built digital twin maintained across the vessel’s service life — for ongoing asset management and engineering.
Explore 02Vessel Condition Survey
An accurate record of the vessel as it exists today — pre-purchase, pre-refit, or for insurance and class documentation.
Explore 03Damage Assessment
Precise 3D documentation of damage extent following an incident — for owners, insurers, repair yards and engineers.
Explore 04Refit & Conversion Survey
As-built capture before refit or conversion begins — the data that keeps engineering accurate and dry-dock time short.
ExploreMeasure Once, Engineer With Confidence.
A vessel in dry dock is in the most expensive place it can be. Accurate as-built data, captured up front, de-risks everything downstream — stability calculations, modifications, system installs, retrofits and electrification — and cuts the time an asset spends out of service.
Clashes found in a model cost nothing to fix. Clashes found during installation cost yard time and rework. The digital twin moves that discovery left — before any steel is cut.
Capture the As-Built.
Engineer the Change. Deliver It.
Survey is where every Isca project starts — but it doesn’t end there. The captured data feeds straight into the engineering, and we stay on the job through to a working result.
Survey & Digital Twin
Survey-grade scanning and digital twin capture — the accurate as-built foundation everything else is built on.
Engineer the Change
Naval architecture, marine engineering, electrification and hybrid power — designed on the captured data, not on assumptions. See engineering services →
See It Through
Retrofit supervision, systems integration and commissioning support — from data capture through to delivery on site.
Relevant Sectors.
The survey-first model is especially relevant to anyone planning a retrofit, modification or electrification of an existing asset — the situations where outdated drawings cause the most cost and delay.
