Accurate fabrication measurements with less vessel time
Subsea jumper and spool fabrication requires precise measurements between assets. Zupt’s inertial metrology service uses C-PINS to obtain these measurements, saving an average of 50% vessel time compared with traditional LBL acoustic metrology methods.
These time savings reduce costs and improve productivity for offshore marine construction projects worldwide.
How C-PINS Supports Offshore Operations
C-PINS is a self-contained inertial navigation system that requires a single subsea connection to the ROV for power and communication. It can be interfaced on vessels, rigs, or barges equipped with a work-class ROV.
The one-connector interface and short communication checks reduce setup time, allowing the survey team to begin work without complicated interfacing.
C-PINS eliminates the need to install an acoustic metrology array. It delivers measurements comparable to traditional LBL acoustic metrology methods, with a significant speed advantage, and operates effectively in shallow water or in the presence of drilling noise and vibration.
Operational Benefits
- Reduced vessel time: Average vessel time savings of 50% compared with traditional LBL acoustic metrology.
- Simple ROV interface: One subsea connection for power and communication.
- Less setup work: No acoustic array installation required.
- Precise measurements: Provides the measurements needed for jumper or spool fabrication.
- Real-time quality control: Supports decisions throughout data collection.
- Fast delivery: Final deliverable provided within 24 hours after data collection is complete.
- Together, these capabilities reduce operational costs and project timelines while improving offshore productivity.
Experience and Quality Control
Over the years, Zupt has completed more than 400 inertial metrologies.
During data collection, real-time quality control provides precise assessments in millimeters or fractions of a degree. This allows clients to make informed decisions while survey operations are underway.
Fabrication Deliverables
The final deliverable contains all metrology data required for jumper or spool fabrication and is provided within 24 hours after data collection is complete, minimizing project downtime.
