Survey & Digital Twin

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.

What This Covers

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.

01

3D Laser Scanning

High-density survey-grade scanning — under scaffold, in confined spaces, or on the water.

02

Point Cloud Processing

Raw scans registered, cleaned and aligned into a single dimensionally reliable point cloud at a known tolerance.

03

Digital Twin Capture

An accurate 3D model of the captured spaces — suitable for clash detection, routing and downstream design.

04

Confined & On-Water Survey

Capture in machinery spaces, tanks and afloat, where conventional measurement is slow and error-prone.

05

Reverse Engineering

Deriving usable geometry from the as-built where original drawings are missing or out of date.

06

As-Built Models

Verified dimensional models and extracts that replace unreliable legacy drawings for the scope of work.

Why It Matters

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.

From Data to Delivery

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.

01 / CAPTURE

Survey & Digital Twin

Survey-grade scanning and digital twin capture — the accurate as-built foundation everything else is built on.

02 / ENGINEER

Engineer the Change

Naval architecture, marine engineering, electrification and hybrid power — designed on the captured data, not on assumptions. See engineering services →

03 / DELIVER

See It Through

Retrofit supervision, systems integration and commissioning support — from data capture through to delivery on site.

Who It’s For

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.
