Versatile MRUs for every budget and requirement
Find your perfect MRU solution designed to meet different budgets and requirements without compromising on quality, functionality, flexibility, performance, or cost-effectiveness.
Roll and pitch dynamic accuracy of 0.05° Heave accuracy: 5 cm / 5 %
The 6000 series improves it further to 0.02°
The 9000 series achieves exceptional precision with 0.01°
Which series should I choose?
This depends on your application, here are some general guidelines
The 3000 series, with 0.05° accuracy in Roll & Pitch, is ideal for most monitoring applications where the main purpose is to collect motion data for analysis or decision making. This model is also suitable for some control applications, such as AHC for smaller vessels with short lever arms to the remote monitoring points.
The 6000 series, with 0.02° accuracy in Roll & Pitch, is our most versatile MRU due to its high accuracy and is suitable for most applications. This is the recommended MRU for most control applications such as AHC and winch control.
The 9000 series, with 0.01° accuracy in Roll & Pitch is our most accurate MRU. We recommend this MRU for sensor compensation applications such as hydrography, and for advanced control applications such as 3D motion compensated gangways.
Market-leading performance in real sea conditions
Many suppliers tend to present test data solely for simple regular motions observed in laboratory conditions. Unfortunately, vessels experience irregular and coupled motions at sea. While most sensors perform well in sine wave motion, only a select few excel in irregular sea conditions.
Norwegian Subsea's unique sensor fusion algorithms get the most out of high accuracy sensors, providing high-accuracy motion measurements in any sea condition.
Easy interfacing and configuration
The free Windows-based NORSUB MRU Configuration Software is used to set-up the MRU. Here you can configure the communication ports, customize the output data protocol, configure the MRU installation parameters, set up remote monitoring points, calibrate the magnetometer. The software can also update the MRU firmware, log the MRU data to file, and plot output data.
