Description
Product Overview
Kongsberg MRU-M-MB2 is a mechanical mounting bracket accessory designed for Kongsberg Maritime Motion Reference Unit (MRU) inertial sensor systems. It is part of the MRU mechanical installation accessory family and is used to securely mount the MRU sensor unit onto marine vessel structures. The MRU-M-MB2 provides a stable mechanical interface between the vessel structure and the motion sensor, ensuring accurate measurement of roll, pitch, heave, and other vessel motion parameters required by navigation, positioning, and offshore operations.
Kongsberg MRU-M-MB2 is engineered specifically for marine inertial measurement applications where installation accuracy and mechanical stability directly influence sensor performance. Motion Reference Units rely on precise alignment and rigid mounting to achieve reliable measurements. The MRU-M-MB2 bracket helps maintain correct sensor orientation, minimizes unwanted movement caused by vibration, and supports consistent data output from the MRU system during vessel operation.
Kongsberg MRU-M-MB2 belongs to the Kongsberg MRU accessory ecosystem, which includes various mounting brackets, junction boxes, subsea accessories, and connection solutions for different vessel and offshore installation requirements. Proper mechanical installation using accessories such as MRU-M-MB2 improves system reliability and helps ensure that MRU measurements can be effectively used by dynamic positioning systems, hydrographic equipment, stabilization systems, and marine control platforms.

MRU-M-MB2
Main Features and Advantages
Kongsberg MRU-M-MB2 provides a dedicated mechanical installation solution for Kongsberg MRU motion reference systems. Unlike general-purpose mounting hardware, MRU-M-MB2 is designed according to the mechanical requirements of marine inertial sensors, ensuring that the MRU remains securely positioned during vessel operation.
One of the major advantages of Kongsberg MRU-M-MB2 is improved measurement reliability. Motion sensors require accurate alignment with the vessel coordinate system to calculate motion parameters correctly. A rigid and properly designed mounting bracket reduces installation errors and prevents unwanted movement that could introduce measurement inaccuracies.
The robust construction of MRU-M-MB2 allows it to withstand the demanding conditions commonly found in marine environments. Ships and offshore platforms experience continuous vibration, shock loading, temperature changes, and mechanical stress. The bracket provides a stable installation foundation that helps protect the MRU sensor and maintain long-term operational accuracy.
Kongsberg MRU-M-MB2 also simplifies installation and maintenance activities. Its dedicated design allows technicians to mount and remove compatible MRU equipment efficiently during commissioning, inspection, or replacement procedures. This reduces installation complexity and improves maintenance efficiency for marine automation systems.
Another important benefit of MRU-M-MB2 is system compatibility. Using original Kongsberg mounting accessories helps ensure that the MRU sensor is installed according to manufacturer recommendations, maintaining the intended performance characteristics of the complete motion sensing system.
The compact and practical design of MRU-M-MB2 makes it suitable for various vessel installations where space optimization and mechanical stability are important considerations. Together with Kongsberg MRU sensors, the bracket contributes to reliable motion measurement for navigation, positioning, and marine automation applications.
Applications
Kongsberg MRU-M-MB2 is primarily used in marine and offshore applications requiring accurate motion reference measurements. The bracket is installed as part of Kongsberg MRU systems used to measure vessel movement and provide motion data to onboard control systems.
In dynamic positioning (DP) systems, Kongsberg MRU-M-MB2 supports the installation of motion sensors that provide essential roll, pitch, and heave information. Accurate MRU data allows DP controllers to compensate for vessel movement and maintain position during offshore operations.
In hydrographic surveying and marine research vessels, MRU-M-MB2 helps maintain the correct installation position of motion sensors used for compensation of vessel movement during sonar and survey operations.
Offshore platforms, drilling vessels, and construction vessels also use Kongsberg MRU-M-MB2 as part of their motion measurement infrastructure. Stable sensor mounting improves operational reliability in environments where accurate vessel movement data is critical.
Typical application areas include:
- Dynamic positioning systems
- Offshore vessels
- Survey vessels
- Research ships
- Marine navigation systems
- Hydrographic measurement systems
- Subsea operations support vessels
- Vessel stabilization systems
- Kongsberg MRU installations
