Ship Repair & Shipbuilding Metrology — We’ve got you covered

Marine metrology services from TNT Metrology support ship repair and shipbuilding projects worldwide. Using 3D scanning, dimensional inspection, and precision alignment, we help shipyards, defence contractors, and service teams reduce rework, accelerate dockings, and deliver class-ready results. From shaft lines and gearboxes to hull blocks and retrofit integrations, our experts provide accurate, traceable outputs for every stage of the marine lifecycle.

What We Do for Ship Repair & Shipbuilding

TNT Metrology delivers dimensional control, precision alignment, and reverse engineering tailored for marine environments—dry-dock, afloat, or in yard. We keep refits and new builds on track worldwide.

Shaft line & gearbox alignment — laser tracker alignment of main engines, gearboxes, bearings, and stern tube to minimise vibration and wear.
Hull & block 3D scanning — capture complex hull forms, blocks, and modules as point clouds/meshes for clash-checks and as-built documentation.
Rudder, skeg & propeller inspection — GD&T to CAD, clear colour maps, and traceable reports for class surveys and FAI.
Reverse engineering & retrofit support — create accurate models of legacy components and interfaces to de-risk upgrades and integrations.

What We Do for Marine & Offshore

Our marine metrology services help shipyards and repair teams bring vessels back to service faster with less rework.
We combine 3D scanning, dimensional inspection, and
precision alignment.

  • Jig/fixture & foundation verification — machinery seats, inserts, and bolt patterns validated to CAD.
  • Large-scale scanning — hulls, tanks, and superstructures captured for fairing analysis and fit-ups.

Typical Use Cases
  • Dry-dock shaft line alignment & bearing set-up
  • Block/module fit-up & clash-check
  • Rudder stock, pintle & stern gear surveys
  • Tank/void space mapping and deformation studies
  • Retrofit integrations (scrubbers, BWTS, sensors)

Class & quality frameworks: ABS, DNV, Lloyd’s Register, ISO 9001 — we deliver traceable outputs that slot into your workflow.
