High accuracy positioning for marine applications
High-Precision Positioning at the Centimeter Level
A must-have for navigators and engineers conducting complex operations at sea.
Dynamic Positioning (DP) for Marine & Drilling Operations
Precise GNSS is a critical input for dynamic positioning systems used on vessels and offshore platforms across the oil & gas and renewable energy sectors. Accuracy and reliability ensure station-keeping performance, even in challenging marine environments.
Structural Monitoring
Fixed or seabed-anchored offshore structures,including platforms, wind turbines, and buoys, require continuous high-precision monitoring to detect any horizontal or vertical drift. Reliable data helps ensure safety, longevity, and regulatory compliance.
Subsea Construction
Whether laying subsea cables and pipelines, developing subsea fields, or installing and repairing underwater infrastructure, centimeter-level GNSS positioning is vital for precision, safety, and efficiency in every phase of construction.
Surveying & Inspection
From construction and geophysical surveys to UXO detection and pipeline inspections, accurate positioning of vessels and onboard sensors is essential. Precision ensures data integrity and confidence in every decision made from survey results.
Station-Keeping for FPSOs and Floating Wind Turbines
Floating production systems such as FPSOs, along with floating wind turbines, are designed to remain on station for extended periods, even in the harshest marine environments.
To maintain stability, these structures depend on advanced mooring systems that must continuously adapt to changing loads caused by wind, waves, and currents. Geoflex provides high-precision GNSS positioning that enables real-time monitoring and delivers accurate positional data to actuator systems, allowing automatic tension adjustments of mooring lines. This ensures optimal station-keeping and structural integrity in all sea conditions.
This capability is equally essential for floating offshore wind turbines, where precise positioning supports performance, safety, and long-term durability.
Precision Support for Offshore Wind Farms – From Installation to Operation
Offshore wind farms operate in highly constrained environments, where both the construction and operational phases demand extreme precision and reliability.
During the critical building phase, Geoflex delivers high-precision GNSS positioning to ensure accurate placement of turbine masts across all three axes X, Y, and Z. This accuracy is essential to guarantee structural alignment, stability, and performance.
Once the wind farm is operational, Geoflex continues to provide value through continuous monitoring and post-processed analysis. By detecting and analyzing any structural deviation or movement of turbines, operators can anticipate potential issues and schedule preventive maintenance, reducing downtime and extending the lifespan of offshore assets.
