From bathymetric surveys to subsea inspections and wave radar systems, our Motion Reference Units (MRUs) have been put to work in a wide range of challenging environments during 2025. As the year draws to a close we take a quick look back at some of the highlights, applications, and collaborations that helped shape another strong year of progress for Norwegian Subsea.

Norwegian Subsea is bringing its acclaimed Motion Reference Unit (MRU) technology to sonar-based applications with the introduction of an updated MRU lineup featuring full aiding capabilities at Ocean Business 2025 this week.

Dutch company Radac is committed to delivering the most advanced wave radar systems that focus on the task of providing accurate, localised wave and seastate data. To support the highest levels of accuracy and reliability, Motion Reference Units (MRUs) from Norwegian Subsea are used as standard in its WaveGuide radar systems. This has helped build an enviable reputation for quality in the offshore industry, with Radac’s systems widely recognised for enabling confident decision-making in diverse and dynamic marine environments.

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.

Helideck Motion Monitoring & Weather Data Systems (HMS) provide real-time motion and environmental data essential for flight planning and for pilots to remain in safe control during take off and landing from moving helidecks. The HMS depends on Motion Reference Units (MRU) installed directly on to the support structure that continuously measure the helideck’s movement. Leading HMS manufacturer ShoreConnection chooses MRUs built by Norwegian Subsea.
