Ship Motion Monitoring
Precise motion measurements are essential for vessel digitalization, supporting fuel optimization, route planning, cargo safety and structural health.
Ship Motion Monitoring
Continuous monitoring and logging of vessel motions over an extended period can serve as a valuable tool for docking and maintenance scheduling.
Accurate measurement of ship motions is also crucial for assessing the impact of new ship hull designs and modifications to appendices or other structural features.
Ship motion significantly affects the comfort of passengers on ferries and cruise ships. By measuring ship motions, valuable information can be used to optimize ship speed and heading or provide advice to passengers, reducing instances of seasickness.
The NORSUB MRUs reliably and accurately measure all six degrees of freedom year after year. Additionally, measurement data can be logged internally and downloaded as needed. Statistical features, such as significant amplitude and peak frequency over a moving window, can also be measured. For example, the significant heave motion amplitude and peak period during the last hour can be selected as an output measurement.
The NORSUB MRUs are designed for easy installation and use. They are plug and play devices and can be delivered with a junction box or with regular Ethernet (RJ45) connectivity, such as the NORSUB eMRU series. This streamlined approach reduces cable and installation costs, providing a cost-effective solution for ship motion monitoring applications.
