Inertial Metrology using Zupt's C-PINS is a proven and efficient method to accurately determine the measurements required for jumper or spool fabrication between subsea assets. Over the past 16 years, Zupt has completed more than 300 inertial metrologies, which have proven to be more efficient than traditional LBL acoustic metrology methods, consistently saving an average of 50% vessel time. This efficiency translates to significant cost savings and enhanced productivity for offshore marine construction projects worldwide.

Zupt's inertial navigation system, C-PINS, has several advantages, one of which is its simple and efficient design. The system is self-contained and needs only one subsea connection to the ROV for both power and communication, making it simple to connect and communicate on any vessel, rig, or barge equipped with a work-class ROV. This reduction in setup time allows our survey team to immediately get to work, without the delays associated with complicated interfacing. 

In terms of accuracy, Zupt's inertial metrology solution consistently delivers precise measurements required for jumper or spool fabrication.  The data obtained by C-PINS is comparable to that acquired through traditional LBL acoustic metrology methods but with a significant speed advantage. It saves valuable vessel time by eliminating the need for an acoustic array and operates effectively in shallow water or in the presence of drilling noise and vibration.

Another significant benefit offered by Zupt's inertial metrology is real-time quality control. Clients can confidently make decisions during survey operations with precise assessments available in millimeters or fractions of a degree throughout the data collection process in real-time. The final deliverable is provided within 24 hours after data collection, minimizing project downtime, and contains all metrology data required for jumper or spool fabrication.

Inertial Metrology offers a proven, efficient, and accurate solution for determining measurements crucial to subsea jumper/spool fabrication. By maximizing productivity, minimizing project timelines, and reducing operational costs, Zupt's inertial metrology enables faster, cost-effective project completion.
