Applications for Marine operations
Wave Radar
Accurate heave measurements play a vital role in compensating for wave radar measurements when installed on ships or other floating vessels.
Helideck Monitoring
Accurate measurement of roll, pitch, and heave motions is crucial for assessing the safety of helidecks during helicopter landing and take-off operations.
Ship Motion Monitoring
Precise motion measurements are essential for vessel digitalization, supporting fuel optimization, route planning, cargo safety and structural health.
Dynamic Positioning
Dynamic positioning (DP) of vessels necessitates roll and pitch compensation of the GNSS antenna to ensure accurate positioning of the ship's control point.
Motion Compensated Gangways
Accurate measurements of all 6 degrees of freedom are essential for the automatic motion control of gangways.
Offshore Fish Farms
Offshore fish farming presents unique challenges, requiring continuous remote monitoring of all onboard systems, including roll, pitch, and heave motions.
Stabilizing Fins
Stabilizing fin and roll damping systems rely on motion sensors to accurately measure the roll motions of a ship.
Wind Lidar Buoys
Metocean buoys, lidar buoys, and other instrument/sensor carrying buoys, need reliable motion measurements to motion compensate pay load sensors, or to collect motion data for post processing.
Hydrography
Accurate measurements of roll, pitch, and heave are crucial for achieving optimal results when compensating multibeam sonars for vessel motion.
Applications for Subsea
Subsea Surveys
Subsea surveys often demand precise tilt measurements (roll and pitch) for various purposes, such as installation tasks or continuous monitoring of tilt changes and deflections in subsea structures.
Riser Monitoring
The NORSUB Subsea MRU is specifically designed to provide highly accurate measurements of roll, pitch (inclination), and lateral motions in risers.
Active Heave Compensation
Accurate measurement of vertical motion at the crane tip or winch is crucial for the operation of Active Heave Compensated (AHC) cranes and winches.
BOP Monitoring
Accurate motion sensors play a crucial role in the structural monitoring of Blowout Preventers (BOPs), enabling the measurement of inclination and lateral displacements.
ROV/AUV
Reliable motion sensors are vital components in the navigation system and motion compensation of payload sensors for ROVs and AUVs.
Applications for Wind energy
Wind Turbines
Accurate and precise motion monitoring is crucial for wind turbine towers to ensure structural integrity and optimize performance.
Floating Wind Turbine Control
For floating offshore wind turbines, precise measurement of roll and pitch motion of the wind mast caused by waves is crucial.
Floating Wind Base Motion Monitoring
Monitoring the movements and structural integrity of floating wind foundations, including both the base and turbine, along with the anchoring system, is crucial.
Wind Lidar Buoys
Metocean buoys, lidar buoys, and other instrument/sensor carrying buoys, need reliable motion measurements to motion compensate pay load sensors, or to collect motion data for post processing.
