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Deriving usable geometry from the as-built where original drawings are missing or out of date.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.
Measure 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.
