Norwegian Subsea

Norwegian Subsea introduced a new series of Motion Reference Units (MRU). The NORSUB series of MRUs are high performance, compact and cost effective. They are made specifically for marine applications where high dynamic accuracy, compact size and cost effectiveness are important. Dynamic roll & pitch accuracies range from 0.01 to 0.10 degrees at rates up to 1,000 Hz. The combination of high accuracy and cost-effectiveness is achieved due to state-of-the-art MEMS sensors and new, computationally efficient sensor fusion algorithms.

They particularly featured Motion Reference Units (MRUs) and subsea motion sensors.

They also introduced a series of MRUs with very high dynamic accuracy, high output frequencies and robustness at prices more affordable than what is currently found in the market. They believe their MRUs have price/performance-ratios that are among the most attractive in the market space.

The MRUs are used by/of use to: Hydrography, dynamic positioning, active heave compensation, sonars, fishery, hull monitoring, navigation and other motion compensation purposes.

Other exhibits on their stand included: NORSUB 6000 subsea motion sensor; a high performance and compact subsea motion sensor with low power consumption. Outputs roll, pitch, heave and heading at frequencies up to 2,000 Hz. Depth rated to 6,000 m. These are used by/of use to: Subsea survey companies, ROV manufacturers, ROV operators, subsea installation companies, wellhead/BOP monitoring, asset integrity, ROV/AUV.

Their exhibits were particularly relevant to those attending the Hydrography, Geophysics and Geotechnics; Monitoring Structural Integrity: Understanding Risk and Reliability; Positioning & Metrology; and Unmanned Vehicles and Vessels Showcase conference streams. Their products use state-of-the-art MEMS technology and ground-breaking, new sensor fusion algorithms to provide real-time attitude measurements at very high frequencies,
