Zupt

Following a series of recent inertial metrology projects, our team is mobilizing for another campaign in Nigeria.

The project will utilize Zupt's C-PINS inertial metrology system to conduct a jumper metrology. Accurate subsea positioning is critical when performing metrology, requiring reliable measurements and real-time quality control throughout the campaign.

The compact, single-connection system supports rapid deployment while delivering survey-grade measurements for critical subsea positioning applications.

During offshore wind installation, crews are often working with limited visibility to monopiles, vessel movement, environmental forces, and tight installation tolerances. Small positioning errors can quickly turn into lost time offshore, additional vessel costs, or rework.

That's why real-time positioning, monitoring, and measurement play such an important role throughout the installation process.

Whether it's subsea template monitoring, monopile installation support, transition piece alignment, or creating digital models that help teams understand what's happening in real time, the goal is the same: give crews the information they need to make confident decisions when conditions are less than perfect.

Our team will be attending Global Offshore Wind this week, and we're looking forward to connecting with people across the industry.

If you're working on offshore wind installation projects and facing challenges around positioning, monitoring, or installation accuracy, we'd love to chat.

Corrosion, free spans, and anode depletion aren't difficult to identify during a pipeline inspection.

Understanding their extent is often the greater challenge.

Without detailed inspection data, it can be difficult to fully characterize observed conditions and understand what is happening along the asset.

That's where Zupt's contactless 3D Recon V2 technology comes in.

Operating from an ROV or AUV, the system collects the data needed to generate a high-resolution point cloud or mesh model of a pipeline section and the surrounding seabed in a single pass.

By integrating an inertial navigation system with five high-definition cameras, the system accurately models a larger area of visible pipeline and nearby seabed while creating a scalable deliverable.

The resulting model can be integrated with vehicle positioning information to provide the absolute position of the surveyed asset, delivering detailed visibility into:

• Corrosion and anomalies
• Free span length and depth
• Anode depletion

This same 3D Recon technology is also used to generate high-resolution, color-palletized models for the inspection of transmission lines, structures, and as-built infrastructure associated with offshore wind projects.

A monopile doesn't have to be far off position to create a costly problem offshore.

When installation tolerances are tight, even small positioning errors can lead to additional vessel time, rework, and difficult decisions during construction.

That's why accurate positioning and real-time monitoring are fundamental to offshore wind installation campaigns.

Zupt works with offshore wind installation teams to provide the positioning and monitoring data needed during monopile installation, transition piece leveling, and other critical phases of construction.

At Global Offshore Wind 2026, we'll be discussing these challenges and how our technologies support monopile positioning, rate-of-penetration monitoring, and integrated sensor systems.

Another round of metrology preparation is underway as we get ready for an upcoming offshore metrology campaign in Angola.

Using Zupt’s C-PINS inertial metrology system, the team continues supporting offshore operations with fast mobilization, real-time quality control, and reliable subsea positioning data. The compact single-connection setup helps simplify offshore deployment while maintaining the accuracy needed for demanding subsea work.

Early in developing 3D Recon, we realized high-resolution subsea modeling required more than cameras and navigation systems.

It required acquisition planning tools that could estimate survey coverage before going offshore.

So we built 3D Recon Painter, a planning and simulation tool designed to evaluate subsea survey coverage before acquisition begins.

The concept is simple

Import a CAD or STL model of the structure into the software and simulate the survey before deployment.

The system evaluates coverage based on:

🔸 Planned trajectory
🔸 Line spacing
🔸 Along-track speed
🔸 Vehicle offset from the structure

Before acquisition starts, crews can estimate:

🔸 Coverage quality
🔸 Survey duration
🔸 Expected data volumes

Then offshore, the same system runs live using navigation data streamed directly from the ROV.

As data is collected, the structure transitions from red to green in real time to show where sufficient coverage has been achieved for high-resolution modeling.

The goal is straightforward:
Make subsea reality capture more predictable, repeatable, and operationally scalable.

Tools such as 3D Recon Painter can reduce the need for dedicated survey specialists offshore by giving crews a live visual interface to confirm coverage during acquisition.

Sometimes the biggest improvement in offshore workflows isn’t better sensors.
It’s giving operators better visibility into the data they’re collecting.

In theory, shallow water is supposed to simplify offshore survey, but in practice, it often makes metrology harder. Acoustic multipath is often a difficult and time-consuming problem to overcome, which adds complexity and vessel time to what would seem like a straightforward LBL metrology.

Zupt actively pushes for clients to use C-PINS as a time-saving metrology solution, ESPECIALLY in shallow-water environments.

Zupt’s C-PINS system delivers:

🟧 Millimeter-level accuracy in any water depth
🟧 No acoustic array requirement
🟧 Reliable performance in noisy environments
🟧 Faster deployment and accelerated turnaround

Instead of working around acoustic limitations, the approach removes many of them entirely.

For operators focused on reducing offshore time while maintaining positioning confidence, that changes the conversation.

Especially in shallow-water projects where efficiency matters just as much as precision.
