3D scanning in the maritime sector

3D scanning is applied in refits, retrofit projects, clash detection, dimensional control for prefabricated components, and verification of existing installations. It is also used for reverse engineering of components and as input for digital models and digital twins.

Unlike manual measurements, 3D scanning delivers a complete and consistent dataset of the existing situation. This eliminates assumptions, reduces measurement errors, and enables design decisions to be validated directly against real-world geometry.

3D scanning is particularly valuable in complex, poorly documented, or hard-to-access environments. Typical use cases include retrofit projects, existing vessels, or installations where discrepancies between design and reality are significant.

The greatest value lies in existing assets, where the actual situation often deviates from available drawings. In newbuild projects, 3D scanning is mainly used for verification, quality control, and as-built documentation.

By working with a single, shared, and up-to-date dataset, design decisions are better substantiated and clashes become visible at an early stage. This reduces rework, prevents surprises during installation, and shortens project lead times.

Handheld SLAM scanners offer speed and flexibility in complex environments but with lower accuracy. Static laser scanners provide higher precision and detail but require more setup positions and time on-site. The choice depends on the required accuracy and project objectives.

A typical workflow includes on-site data acquisition, registration of scans into a unified coordinate system, cleaning of noise and measurement errors, and delivery in the required format (e.g., point cloud, mesh, or CAD). Post-processing often represents the largest share of the total effort.

Depending on size and complexity, lead times typically range from several days to approximately one week, including registration and delivery. Office-based processing time is generally significantly longer than the actual scanning.

Investment in 3D scanning results in reduced rework, shorter lead times, and improved design quality. Especially in complex projects, these benefits significantly outweigh the initial costs.

Scan data is typically managed according to project-specific agreements, often stored on client-side infrastructure. Access and distribution are aligned with the client’s requirements, with options for secure online viewers if needed.

3D data provides a reliable foundation for digital asset representations. It supports applications such as digital twins, lifecycle management, and remote monitoring, provided the data is structured and stored for reuse.

A logical first step is to execute a pilot scan within a specific project. This makes the added value immediately tangible and helps determine how to integrate 3D scanning into existing workflows.
