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.

MRU Subsea

Roll and pitch dynamic accuracy of 0.05° Heave accuracy: 5 cm / 5 %

The 6000 series provides high performance 0.02° roll and pitch accuracy

The 9000 series achieves exceptional precision with 0.01° roll and pitch accuracy

Product overview

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.

The Subsea MRU is available in three versions, 3000, 6000, and 9000, to cater for different accuracy requirements and budgets.

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.
