3D Data Analysis


Ashtead Technology provides innovative measurement solutions allowing complex and critical measurements to be extracted from subsea 3D data.

Starting with raw subsea 3D imaging and metrology data from our laser, photographic, video, and sonar imaging technologies, models are interrogated to obtain critical dimensions such as:

  • Linear and angular measurement
  • Flatness and circularity deviation
  • Interference between components
  • Area and volumetric calculations

We provide accurate measurements to facilitate construction, installation, repair, and replacement activities, including rapid results for time-critical applications.

Our subsea 3D modelling solutions can be used to create digital twins, combining real world subsea 3D data with as-built dimensions, or to create solid objects with optimized meshes for finite element analysis.
