Which marking solutions for the maritime sector?
Mark durable identifiers on parts and plates with our marking machines built to resist marine conditions and support compliance.
Naval assets, ships and equipment are maintained and go through quality control along their lifecycle. Components such as pipe spools, propeller hubs, ladders/handrails, control cabinets and much more require permanent identification to ensure correct traceability.
In 2024 alone, new shipbuilding contracts were reported at $204 billion worldwide, underlining how much value flows through shipyards and their supplier networks. A market of that scale requires efficient monitoring of systems, equipment, tools and assets.
To answer those needs, the solution is to use production-ready permanent marking systems (laser, dot peen, scribing, and rotary) that keep critical identifiers readable for decades despite corrosion, cleaning, repainting. This secures part history throughout the asset’s lifecycle, reduces assembly errors, and improves inspection processes and spare-part management.
Which marking machines for the maritime sector?
Mark serial numbers, datamatrix, and fine text, with excellent consistency and high-definition on small parts, panels, assemblies, cabin hardware, structural subassemblies with Class 1 marking solutions for the maritime sector. Laser stations are the go-to choice for naval and maritime production as it keeps the process safe, enclosed, and repeatable, while delivering sharp results and the ability to mark parts of different sizes. Address every naval application thanks to the compatibility of our stations with our laser sources: Fiber, MOPA, Hybrid, and Green.
- WeLase™: compact laser station for precise traceability marking of small naval components and cabin parts.
- LW2: automated laser workstation ensuring safe, repeatable marking of electrical cabinets and engine parts.
- LW3: large enclosure for secure marking of structural boat components and oversized assemblies.
For parts exposed to abrasion, corrosion, vibration, repainting, and heavy handling, dot peen is often the most trusted approach: it creates a physical indentation that remains readable over time. Thanks to its deep marking of up to 0.3mm, it is particularly relevant for pipes, mechanical parts, metal fittings, and treated parts, where surfaces tend to degrade gradually because of their exposure to humidity and marine atmospheres.
Dot peen also integrates well into maintenance workflows: mark, inspect, repaint, and the identifier is still there.
When marine components must stay identifiable through abrasion, vibration, corrosion protection processes, and repainting, scribing is a strong choice. It produces a deep, continuous, clean line mark that is highly readable, while remaining quiet: a real advantage in workshops and onboard maintenance environments. Scribing is particularly relevant for metal parts such as valve bodies, pump housings, brackets, clamps and more.
When the requirement is engraved identification plates, tags, and informative signage, often in engine rooms, control areas, and offshore modules, CNC engraving is a reliable standard. It produces crisp, deep marking on a wide range of engraving materials and metals, and is ideal for structured layouts such as tags, plates, but also serves for deep part marking.
CNC stations are a strong fit when your traceability marking needs to remain readable for years even after cleaning, exposure, and routine maintenance.
For workshops producing signage, nameplates, labels, and cut-to-size plates for the maritime sector, laser tables combine format flexibility with fast execution: useful when you need to create batches, series, or standardized plate families for different ships or platform zones.
This approach is particularly relevant for shipyards and offshore sites that manage frequent updates (equipment changes, zone signage revisions, refurbishment campaigns) while demanding durable, readable results.
With a CO2 laser source for plastics and Fiber for metals, our permanent marking systems easily answer to plate marking and cutting.

What are the main regulations in the maritime sector?
Traceability and compliance references
Naval and offshore identification is usually driven by traceability and compliance. In practice, requirements typically come from:
- Class/shipyard quality frameworks (e.g., IACS shipbuilding quality guidance) that expect consistent part identification linked to inspection records.
- Material certification traceability, where marked IDs (heat/batch/part numbers) must match inspection documents such as EN 10204 (3.1/3.2) and project documentation.
- Offshore project practices (e.g., NORSOK material data sheets) specifying marking to maintain full traceability to melt/lot and heat treatment.
- Regulatory equipment marking (e.g., EU MED “wheelmark” on applicable marine equipment) with durable nameplate content.
- For naval military programs, UID/IUID marking, often using a 2D Data Matrix (ISO/IEC 16022) is usually required.
Gravotech supports these needs by marking unique part/asset IDs, serials, heat/batch numbers, and durable plates with marking solutions for the maritime sector.
| Depending on where you operate, export-control administrations and security constraints may also influence what can be marked, how data is structured, and where it can be stored or shared. |
What are the main applications for marine traceability marking?
Shipbuilding, refit yards and supply chain
Manage high part volumes and long production timelines with clear, permanent IDs for across multiple tiers:

| FAQ: The 6 questions most frequently asked of our experts |
|---|
🔽Which marking technology should I choose for marine environments?
It depends on the part and exposure: laser for high-contrast IDs and 2D codes, dot peen/scribing for deep marks that survive abrasion/repainting, and CNC engraving for durable plates, tags, and signage.
🔽What information should be marked to ensure traceability in shipbuilding and offshore projects?
Typically: part/asset ID, serial number, batch/heat number, drawing revision, line/spool ID (piping), equipment tag number, and when required, 2D codes to speed up scanning and inspections.
🔽Will the marking remain readable after corrosion, cleaning, and repainting cycles?
Yes, if the method is adapted: deep dot peen/scribing is usually best for repainting/abrasion; laser can be highly durable on suitable materials; engraved plates remain readable in harsh zones when installed correctly.
🔽Can we mark large or awkward parts (structures, frames, oversized assemblies) safely and repeatably?
Yes. Large Class 1 laser enclosures and suitable fixturing/workholding enable secure marking of bigger components, while dot peen can be used directly on many large metal parts when access allows.
🔽How fast is the marking process, and can it keep up with shipyard production?
Usually a few seconds, cycle time depends on content (text vs. 2D code), mark depth, and material. With optimized templates, parameters and proper fixturing, marking can be integrated into production flow with consistent results shift after shift.
🔽How do we standardize marking across subcontractors and multiple sites?
Use common data formats (part ID rules), shared layouts/templates, locked parameters, and validation steps (e.g., 2D code verification). This ensures the same identification quality across your supply chain and over the asset lifecycle.
