It is not always a matter of which method is "better," but which method is better for your specific scenario.
Some questions we like to ask when a client requests a metrology from Zupt:
- Are there receptacles already installed on the structure? If not, can custom metrology receptacles be designed?
- Is the metrology taking place from a drill rig?
- Does the client need the metrology deliverable within 12 hours of the survey?
- Is the metrology site somewhere geographically difficult to mobilize to?
- How valuable is saving an hour of vessel time?
- What are the required metrology tolerances?
Zupt's C-PINS inertial metrology solution is a trusted solution, having been used for years in the industry by Super Majors, Tier 1 Contractors, and Survey Contractors without fail.
The solution involves directly interfacing with metrology receptacles, providing the highest level of confidence in the attitude of the hub face.
- Surveys are often completed within 6 hours
- Offshore deliverables can be provided in as little as 12 hours
- Can be completed fully remotely, meaning no personnel visas, no day rate, and less hassle for the client
Zupt's 3D Recon solution is based on dynamically collecting imagery data that is processed into a very high-resolution 3D model of the metrology site and is completely contactless.
- Surveys can be completed in just a few hours
- Models can be processed offshore to meet standard offshore deliverable timelines
- Eliminates the need for receptacles or custom tooling through a point cloud-based approach
- Zupt takes exceptional care in these situations to directly model hub faces and provide metrology attitude accuracies while reducing assumptions or inferred measurements.
- The final result is still a metrology report used for fabrication, with the added benefit of a high-resolution, color-palletized 3D model of the assets.
Instead of specifying a certain technology or provider, Zupt aims to have a conversation about the survey itself and help guide clients to the right solution.
The goal is to deliver accurate results, save vessel time, and make the entire metrology process as efficient as possible.
