Survey & Digital Twin

The Vessel As It Is. Not As It Was Designed.

A vessel condition survey captures the current physical state of your asset with survey-grade accuracy — geometry, structure and systems layout as they exist today, not as the original drawings intended.

When You Need It

Before You Buy, Refit, Modify or Plan.

01

Pre-Purchase / Acquisition

Accurate dimensional and spatial data before committing to a purchase — knowing exactly what you’re acquiring, including any modifications from original specification.

02

Pre-Refit or Modification

The as-built record that retrofit designers, engineers and yards need before any meaningful scope can be written. Prevents errors, mismatches and costly rework.

03

Post-Modification Record Update

Updating the vessel’s record after modifications, repairs or equipment changes — so the documentation reflects what’s actually there, not what was originally specified.

04

Insurance & Valuation

A precise technical record of the vessel’s current configuration and condition, suitable for underwriter, broker or insurance assessor reference.

05

Class & Flag Documentation

Survey-grade dimensional data and as-built records to support class submissions, flag state notifications and technical documentation requirements.

06

Technical Due Diligence

An objective technical record of the vessel’s actual condition and configuration — for investors, lenders and asset managers making decisions based on real data.

Survey Scope

What a Condition Survey Captures.

01

Hull Geometry & Envelope

Full external hull form — keel, waterline, freeboard, deck line, transom geometry. Accurate enough to feed hull form analysis, stability checks and structural assessments.

02

Internal Structure & Compartments

Bulkheads, frames, decks, stiffeners and structural members documented spatially. Compartment dimensions accurate to survey grade — no tape-measure approximations.

03

Machinery & Systems Spaces

Engine room, generator spaces, auxiliary machinery — positions, clearances and routing captured. Provides the spatial record for any downstream mechanical or electrical engineering.

04

Deck Arrangements & Superstructure

Wheelhouse, accommodation, working deck layout, crane and winch positions, deck fittings — documented as installed, not as originally drawn.

05

Access, Openings & Penetrations

Hatch positions and sizes, watertight door locations, pipe and cable penetrations — the spatial data that matters for modification design and safety documentation.

06

Modifications & Non-Standard Features

Any departures from original drawings identified and documented — modifications, non-standard installations, structural changes — so engineering work proceeds on the real vessel.

Our Process

Survey, Process, Deliver, Carry Forward.

01

Scope Agreement

Before mobilisation we agree what zones need to be covered, what the data needs to support downstream, and what format the deliverables take. No surprises on either side.

02

On-Vessel Survey

Survey-grade 3D laser scanning carried out alongside, afloat, in dry dock, or under active refit — to the vessel’s schedule. Full access to machinery spaces and confined areas within agreed scope.

03

Processing & Documentation

Scan data registered and processed into the agreed deliverable set. Dimensional reports, compartment schedules and departure notes prepared from the measured data — not estimated.

04

Handover & Onward Engineering

Deliverables handed over with a clear index. If the survey surfaces a downstream scope — refit engineering, modification design, stability work — Isca can pick that up directly from the captured data.
