How do I purchase or contact Norwegian Subsea for sensor solutions?

Norwegian Subsea is a global supplier of high-performance Motion Reference Units (MRUs) and related motion sensor solutions. We work closely with customers to ensure each sensor is configured to meet specific application needs across marine, subsea, offshore, and industrial environments.

To initiate a purchase or consultation, we recommend starting with our “Request a quote” form available at the top right corner of our website. This allows us to collect relevant details about your requirements, including:

Required accuracy level: Series 3000, 6000, or 9000 (Roll/Pitch accuracy from ±0.05° down to ±0.01°)
Operational environment: MRU Compact, MRU Marine, MRU Subsea (6000m-rated), or MRU Ex (hazardous areas)
Integration preferences: Ethernet (UDP, Modbus TCP, Ethernet/IP) or serial communication (RS-232/RS-485)
Specific application requirements such as real-time motion data, VRU vs. MRU functionality, or housing material

Our expert team will assess your input and guide you in selecting the most suitable, cost-effective sensor, whether for a new installation or retrofitting existing systems. All our MRUs use advanced MEMS technology and sensor fusion algorithms, and most models are maintenance-free and do not require recalibration.

Accurate and high-resolution motion sensors are crucial for the structural monitoring of bridges.

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.

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.

Buildings

Accurate and high-resolution motion sensors are essential for the structural monitoring of tall buildings.

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.

Motion Compensated Gangways

Accurate measurements of all 6 degrees of freedom are essential for the automatic motion control of gangways.

Offshore Fish Farms
