The NORSUB MRU SUBSEA is an ideal choice for accurate and robust subsea motion measurements. With a depth rating of up to 6000 meters, this compact and small-sized motion sensor offers versatility in installation.
The MRU Subsea can be easily placed in various locations due to its small size and footprint. Communication options include ethernet, RS-232, and RS-485/422, while power and communication are facilitated through the Subconn connector.
For enhanced functionality, the Subsea MRU can be equipped with a high-end magnetometer, ensuring precise magnetic heading measurements.
To cater to different accuracy requirements and budgets, the Subsea MRU is available in three versions: 3000, 6000, and 9000 models.
Additionally, the Subsea MRU is offered in an inclinometer version that focuses on continuous monitoring of the roll/pitch angle of subsea templates at a lower cost. This eliminates the need for expensive subsea rentals during installation.
