Submarine Hull Appendage Survey

Client
Naval refit contractor (sample)

Scope
Hull appendages & reference geometry
Deliverable
Verification report vs nominal

Problem

A refit contractor needed independent verification that hull appendages remained within class tolerance after steel repairs, with survey sign-off gating undocking.

Method

Laser tracker network around the dock floor, redundant reference monuments, and direct comparison of measured geometry against nominal offsets.

Result

Deviations quantified and signed off within tolerance in a single shift — the undocking proceeded without survey-driven delay.
