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.

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.
