Motion Reference Units for Offshore Wind Installation and Service Vessels

The MRU of choice for Offshore Wind Installation and Service Vessels

Offshore wind installation and service vessels operate in harsh sea conditions, where the reliability of every onboard system directly affects safety, operational windows, and project efficiency. Our MRUs serve as the precision motion reference across multiple critical systems on these vessels, from active heave compensation and motion-compensated gangways to dynamic positioning, wave radar, helideck monitoring, and ship motion monitoring.
