MRU Compact | Norwegian Subsea

The MRU Compact is a small-footprint unit with an easy installation process, supporting various communication protocols and featuring a dust and splash-proof design.

MRU Compact

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 NORSUB MRU Compact is a small, yet accurate motion reference unit that is easy to install due to its passive Power over Ethernet (PoE) interface. A regular RJ45 Ethernet connector is used for both power and communication so that any cat5e cable can be connected. This makes installation fast and cabling costs low.

The MRU Compact is configured via Ethernet (TCP) and measurements data can be acquired from UDP messages, Modbus TCP or Ethernet/IP.

The MRU Compact dust and splash proof and is suitable for mounting indoors or inside a control box.

The MRU Compact comes in three different versions: 3000, 6000 and 9000 models to accommodate for different accuracy requirements and budgets.

The MRU Compact is also available in an inclinometer version of the MRU Compact that does not include Heave/Surge/Sway outputs.

High Accuracy

High accuracy roll, pitch and heave, even in irregular sea states.

Power over Ethernet

RJ45 or RJ50 connector with Passive Power over Ethernet (PoE) makes installation easy and cabling costs low.

Very Compact

Low weight and small footprint enable installation almost anywhere.

Easy to use

All Norwegian Subsea Motion Reference Units (MRUs) can be easily configured using the MRU Configurator (free of charge).

Simply define the communication ports and protocols as well as the MRU mounting orientation and location, and you are ready to go.

The MRU Configurator is also a great tool to monitor the outputs in real-time, plot the variables, check the on-board diagnostics and update the MRU firmware.

Miros-Group reduces wave radar maintenance and lifetime costs using Norwegian Subsea Motion Reference Units

Motion Reference Units (MRUs) are crucial in wave radar technology, providing precise measurements of platform motion to accurately separate true wave patterns from a vessel's movements, therefore ensuring reliable data for maritime operations. However, before leading wave radar manufacturer Miros started working with Norwegian Subsea in 2016, it could be said that the MRU market was holding their potential back.

Making Structural Health Monitoring smarter with Motion Reference Units

As the maritime industry accelerates its journey towards smarter, more efficient digital operations, structural health monitoring systems are playing a central role in operational efficiency, safety and sustainability. These systems increasingly depend on real-time, high-fidelity data from Motion Reference Units (MRUs) to contextualise structural stresses with the vessel’s motion in a given sea state. This is especially important in meeting the evolving requirements of classification society SMART notations from bodies such as the American Bureau of Shipping (ABS) and DNV.
