Generate 3D models of underwater assets to identify problems and make the best possible decisions. Welaptega 3DM® is a state-of-the-art visualization system for inspecting and measuring subsea assets such
as umbilical riser bases, pipelines mooring lines and wellheads. 3DM® produces up-close, high-resolution stereoscopic
models that can be manipulated and measured to assess the extent of a problem and make repairs on a subsea component. The Technical Solution
Build geometrically accurate 3D models of subsea assets. Welaptega 3DM® generates accurate 3D models of
underwater components. High resolution digital images are processed using advanced photogrammetric software. 3DM® automatically processes multiple, consecutive overlapping images to create 3D models which are geometrically and dimensionally accurate. The three-dimensional images
are scalar models which give unprecedented detail of surface materials condition.
This enables engineers to characterize the effects of deteriorative mechanisms, for example: wear, corrosion and pitting. An accuracy of >0.1mm is easily
achievable with 3DM®. It also enables users to make direct measurements, calculate areas and volumes, and conduct a full array of dimensional analyses (e.g. cross sections, minmax analyses). This makes 3DM® suitable for design, planning and

Underwater asset failure can compromise production, cost money, impact the environment and hurt your reputation. The Business Solution Introduce a real-time 3D view to your subsea assets. Welaptega’s 3DV® gives a clear, real-time picture of underwater assets to help operators identify problems and make the best decisions. 3DV® also enables ROV pilots to carry out complex construction and repair operations more efficiently. This has been proven to reduce costs significantly
The Technical Solution 3D visualization for inspection and manipulation. Stereoscopic video images provided by Welaptega 3DV® add unprecedented spatial perception for real-time inspection tasks in underwater operations.
Using 3DV®, ROV crews can perform manipulation tasks more quickly and with greater precision than with 2D guidance. Welaptega 3DV® is comprised of a compact underwater camera unit and a top-side display unit. The underwater cameras are available in a number of configurations, from small light-weight mini 3D systems designed for observation ROVs to more robust 4000m-rated 3D systems for work-class ROVs. The 3DV® uses polarizing technology similar to that used by 3D IMAX™ to create realtime 3D visualization. The top-side unit is comprised of a standard 17" CRT monitor, a stereoscopic video display unit, and LCD polarizing screen with polarized glasses for the operator and viewers. 3DV® specifications Deployment requirements • Work-class ROV
• Welaptega 300 – 4000m-rated Target surface preparation required:
