Description
The KONGSBERG MRU-M-MB3 is a Motion Reference Unit (MRU) designed for measuring and recording roll, pitch, and heave (vertical motion) in various marine and offshore applications.
Here’s a breakdown of its key features and functionalities:
-
Motion Measurement: The MRU-M-MB3 uses micro-electro-mechanical systems (MEMS) technology to measure the angular orientation (roll and pitch) and vertical movement (heave) of a vessel or platform at sea.
-
Marine and Offshore Applications: Primarily used in offshore environments for applications like:
- Offshore Riser Monitoring Systems: Monitoring the movement of risers (long, flexible pipes connecting platforms to subsea equipment) to ensure their safety and integrity.
- Dynamic Positioning Systems: Providing accurate motion data for dynamic positioning systems that help vessels maintain their position using thrusters.
- Telecommunication Antenna Systems: Stabilizing antenna platforms on ships or offshore structures for reliable communication.
- Motion Damping Systems: Contributing to motion damping systems that reduce the impact of waves on high-speed crafts.
-
Possible Specifications (Based on Available Information):
- Measurement Accuracy: High accuracy for roll and pitch (likely within 0.08 degrees)
- Heave Measurement: May utilize PFreeHeave algorithms for accurate heave measurement at long wave periods.
- Output Data: Provides real-time roll, pitch, and heave data in various output formats like RS-232, RS-422, and Ethernet for integration with control systems.
- Environmental Rating: Likely has a rugged design suitable for harsh marine environments.
