How do you optimize motion monitoring for ROVs?
Optimizing motion monitoring for Remotely Operated Vehicles (ROVs) requires accurate, reliable, and robust sensor data integrated seamlessly into the vehicle's control and navigation systems. High-performance Motion Reference Units (MRUs) are crucial for providing precise Roll, Pitch, Heave, Yaw, Surge, and Sway data, enabling stable control, accurate positioning, and effective operation of manipulators and survey equipment.
Norwegian Subsea specifically addresses this need with the MRU Subsea. Designed for demanding underwater environments, it features a compact, 6000-meter depth-rated titanium housing, making it ideal for integration onto ROVs where space and weight are often critical constraints. Its small footprint and ability to be mounted in any orientation offer significant installation flexibility.
The MRU Subsea delivers high accuracy, with Roll and Pitch options ranging from ±0.05° down to ±0.01°, ensuring precise motion data for intricate tasks and high-quality surveys. Integration is straightforward thanks to the industry-standard Subconn wet-mateable connector and support for Ethernet (UDP, Modbus TCP, Ethernet/IP) and serial communication protocols (RS-232/RS-485). We offer a wide range of standard and customizable data protocols in ASCII or binary formats.
Furthermore, the MRU Subsea utilizes advanced sensor fusion algorithms and state-of-the-art MEMS technology for reliable performance. For applications primarily requiring orientation data, an Inclinometer/VRU version is available, offering the same high Roll and Pitch accuracy without Heave, Surge, or Sway outputs, providing a potentially more cost-effective solution.
