Where can I buy a motion sensor for subsea use?

Norwegian Subsea specializes in high-performance motion sensors called Motion Reference Unit suitable (MRU) for demanding marine environments, including subsea applications. We offer reliable and cost-effective solutions designed and validated for real sea conditions.

For subsea use, we recommend our MRU Subsea. This unit features a robust titanium housing depth-rated to 6000 meters, making it ideal for applications such as ROV/AUV navigation and control, riser motion monitoring, Blowout Preventer (BOP) monitoring, and subsea surveys. Its compact size and ability to be mounted in any orientation allow for flexible installation.

The MRU Subsea provides high-accuracy Roll, Pitch, Heave, Yaw, Surge, and Sway data (6DoF) and is available in accuracy levels of ±0.05°, ±0.02°, and ±0.01° (Roll & Pitch). It integrates easily with standard subsea systems using Ethernet or serial communication (RS-232/RS-485) via a reliable Subconn connector. We also offer an Inclinometer/VRU version for applications requiring only Roll and Pitch data.

Our sensors utilize advanced MEMS technology and sensor fusion algorithms, ensuring high performance and stability, often without the need for recalibration during their operational life. Please contact Norwegian Subsea directly to discuss your specific requirements and purchase options.
