What is the Typical Applications of Motion Reference Unit ?

MRU is specifically applied in the following applications:

- Active Heave Compensation (AHC)

Information related to the heave amplitude of a crane tip is essential for AHC systems integrated into the equipment, such as offshore cranes. Adequate heave compensation requires access to real-time information from vessel heave motion, velocity, and crane tip acceleration. Roll and pitch data captured by the MRU, integrated into the AHC system, is applied in controlling vessel motion by transferring the heave motion from the tip of the crane to the mounting point of the MRU. The system ensures efficient operation and compensation by adapting to varying conditions and maintaining load stability.

- High-speed motion damping

Systems providing high-speed motion damping or ride control utilize roll and pitch angle and angular rate data for the foil control system. An MRU delivers the required data at a rapid output rate and with minimal latency.
