Norwegian Subsea

What Norwegian Subsea does

Norwegian Subsea is a privately held Oslo-based provider of high-precision Motion Reference Units (MRUs) and motion sensors for marine, subsea, offshore wind, and industrial applications. Founded in 2014, the company designs and manufactures a portfolio of six core MRU models — MRU Marine, MRU Marine SW/SW16, MRU Compact, MRU Subsea (rated to 6,000 m in titanium housing), MRU Ex (ATEX-certified), and ACC Marine — plus VRU variants limited to roll/pitch output, spanning three accuracy tiers from ±0.05° to ±0.01°. The technology stack combines MEMS gyroscopes and accelerometers with proprietary sensor fusion and a Kalman Filter implementation that the company validates in irregular real-sea conditions rather than only in laboratory sine-wave testing. A browser-based MRU Configurator and support-norwegian-subsea.no portal support plug-and-play integration via standard protocols (UDP, Modbus TCP, Ethernet/IP, NMEA, RS-232/485).

The company sells primarily through direct enterprise sales, augmented by a distribution partnership with WASSP for bundled multibeam sonar/MRU packages, and is present at major maritime exhibitions (Nor-Shipping, Europort, Marintec China, Ocean Business, Oceanology International). Its installed base exceeds 1,200 MRUs across more than 600 vessels and subsea structures worldwide, with named customers including Fugro, Oceaneering, Saipem, Brunvoll, Miros, RADAC, ShoreConnection, Light Structures, Ultrabeam Hydrographic, Evotec, Marine Technologies, Hydrauvision, Observator, Ulmatec, Uptime, SH Group, and WASSP. Revenue is generated through hardware unit sales and accessories/integration services; pricing is not publicly disclosed but is positioned as affordable relative to fiber-optic gyro incumbents. Recent strategic activity includes the 2025 launch of an advanced aiding-capable MRU lineup, a WASSP integration partnership, participation in the GASS sustainable-shipping consortium, and an embedded-software collaboration with 99x Yantra Labs in India.

Core offering

Norwegian Subsea designs, manufactures, and sells MEMS-based Motion Reference Units (MRUs) and related motion sensors that measure vessel and structure motion in all six degrees of freedom (Roll, Pitch, Yaw, Heave, Surge, Sway) for marine, subsea, offshore, hydrographic, and industrial applications. The product portfolio spans the IP65 MRU Compact, IP68 MRU Marine (with SW and SW16 shallow-water variants), 6000m-depth titanium-housed MRU Subsea, ATEX-certified MRU Ex for hazardous areas, and ACC Marine, each offered in 3000/6000/9000 accuracy tiers and as Roll/Pitch-only VRU variants.

Product overview

Norwegian Subsea produces industry-leading Motion Reference Units (MRUs) for marine, subsea, and wind energy applications. The product portfolio centers on six core MRU models: MRU Marine (IP68-rated for topside/shallow water), MRU Marine SW/SW16 (shallow water variants with SubConn connectors), MRU Compact (IP65 for indoor/control box mounting), MRU Subsea (6000m titanium-housed deep-water unit), MRU Ex (ATEX-certified for hazardous areas), and ACC Marine. All MRUs provide 6DoF motion data (Roll, Pitch, Yaw, Heave, Surge, Sway) using advanced MEMS sensors and proprietary sensor fusion algorithms, available in accuracy tiers from ±0.05° to ±0.01°. VRU variants outputting only Roll/Pitch are available for all models. Products feature plug-and-play interfaces with standard communication protocols (UDP, Modbus TCP, Ethernet/IP, NMEA, RS-232/485) and browser-based configuration.

Partnerships

Two partnerships are on record, tiered core.

• WASSP (Electronic Navigation Limited)coreTechnology or Integration · 18 March 2025Norwegian Subsea MRUs are now available integrated with WASSP's multibeam sonar systems, offering enhanced motion data accuracy and performance for offshore applications. The partnership enables WASSP users to access motion compensation that performs at RTK-equivalent levels without the cost, complexity, or limitations of land-based RTK base stations. The integrated package is available globally through WASSP's distribution network.
• GASS Project (Green AI for Sustainable Shipping)coreStrategic or Co-development Partner · 1 January 2025Norwegian Subsea participates in the GASS project, a research initiative funded by The Green Platform Initiative exploring integration of motion data into smart shipping systems for vessel performance optimization and carbon reduction. Led by NAVTOR with partners including Grieg Star, Maritime CleanTech, Scandinavian Reach Technologies, Simula Research Laboratory, SinOceanic Shipping, and Sustainable Energy/SIVA.

• Kongsberg Maritime: Kongsberg Maritime is a broad incumbent offering integrated navigation, DP, and positioning suites that include motion-reference functionality; it sells into the same offshore, hydrographic, and shipping customers but as part of a much larger systems portfolio.
• Honeywell Aerospace: Honeywell is a broad incumbent in inertial measurement and navigation sensors across aerospace and industrial segments; while primarily aviation-focused, its MEMS and tactical-grade IMUs set performance benchmarks Norwegian Subsea is benchmarked against.
• Trimble Inc. Trimble provides GNSS and inertial navigation hardware used in marine survey and hydrography; its positioning ecosystem complements or competes with Norwegian Subsea's motion-reference offering in survey-grade applications.

Emerging players

• Advanced Navigation: Advanced Navigation is an emerging player in MEMS and fiber-optic inertial navigation, expanding into marine and subsea use cases with MRU-class products that directly overlap Norwegian Subsea's addressable market.
• VectorNav: VectorNav is an emerging MEMS inertial sensor specialist serving unmanned systems, robotics, and marine autonomy; it competes with Norwegian Subsea at the IMU/MRU level for USV/AUV integration and adjacent small-form-factor applications.

Direct peers

• SBG Systems: SBG Systems is a direct MEMS-based inertial and motion reference peer, offering MRUs, IMUs, and AHRS for marine, survey, and UAV applications with comparable sensor fusion technology competing head-to-head with Norwegian Subsea on price/performance.
• Exail (iXblue): Exail (formerly iXblue) is a leading MRU/INS vendor using fiber-optic gyroscope technology and serves overlapping maritime, hydrographic, and subsea customers; it is the principal premium incumbent Norwegian Subsea competes against on heave accuracy.
