The NORSUB MRU can be set up with industry standard protocols for easy interfacing to the existing DP system, or as replacement for other VRUs. The Marine MRU can be mounted in any direction and the remote monitoring point (GNSS antenna location) can be configured in the configuration software. The NORSUB MRU can be delivered …

Aquaculture
The NORSUB MRU can be mounted anywhere on the fish farm structure and a remote monitoring point can be configured to measure the motions of the center of gravity. Once the NORSUB MRU is installed it needs little or no maintenance for years. This makes it a perfect choice for offshore fish farm and aquaculture …
Wind Lidar Buoys
The small size of the NORSUB MRU makes it ideal for buoy applications. The MRU can be delivered with a high-end magnetometer to provide accurate heading as well. This is useful for calculation of directional wave spectra etc. The NORSUB MRUs come with onboard real-time FFT analysis that is used to output significant motion amplitudes …
Stabilizing fins
The NORSUB MRU provide reliable and accurate roll measurements that can be used for controlling the stabilizing fins or roll damping system. It is easy to interface the MRU with the PLC used for the roll damping system with industrial communication protocols such as Modbus TCP or ethernet/IP.
Ship monitoring
It is also important to measure the ship motions to verify the effects of new ship hull designs and changes to appendices or other structural features. Ship motion heavily affects the passengers’ comfort onboard ferries and cruise ships. If the ship motions are measured, this information can be used plan the ship speed/heading, or give …
Hydrography
When the multibeam sonar and motion sensor are mounted on a moving vessel it experiences horizontal accelerations, and especially during turns. The horizontal accelerations may degrade the roll & pitch measurements which in turn degrades the accuracy of the resulting seafloor map. The motion sensor can be aided by GNSS velocity and position measurements to …
Wave radar
The NORSUB MRU is ideal for wave radar applications due to its very accurate heave measurements also in irregular waves, which is what vessels experience at sea. All motion data is available from the custom protocol if other motion data than heave is needed to compensate the wave radar. Ethernet and serial communication (RS-232 and …
Gangway
As for AHC, it is very important with good measurements of heave motions in real sea conditions. But surge and sway motions must also be measured reliably. The Marine MRU has a special mode for gangway and other DP applications where the wave frequency motion of surge and sway must be measured accurately. This mode …
AHC
The Marine MRU is ideal for AHC applications especially due to its high and reliable performance in irregular waves. Where some other MRUs struggle to give accurate heave measurements in irregular waves, Norwegian Subsea MRUs are designed to deliver the highest performance in real sea conditions. It is easy to interface the MRU with your …
Helideck monitoring
The Marine MRU is ideal for helideck applications with its reliable and high performance in irregular motions that are experienced at sea. The NORSUB MRU has both ethernet and serial communication interfaces, and several industry standard protocols are available for easy interface to the helideck monitoring system. A custom protocol can also be made if …
