Vessel Motion Monitoring systems

Deck Motion Monitor

The Deck Motion Monitoring system extends the weather window for safe offshore crane operations by measuring accurate motion on the cargo deck.

DMM-Relative Motion

The DMM-Relative Motion provides the crane operator with accurate vessel to vessel relative wave motion data.


Human effectiveness is reduced with increased motions. Our DMM-Seakeeping displays motions on multiple deck levels & areas.


The DMM-Personnel displays if the vertical accelerations are within safe limits for personnel lifting and landing.

DMM-Deck View

Multiple functions and areas of use: Live video, playback of recorded video, web service for logistic personnel, and more.

DMM-Simulator Mode

Simulates deck / crane motions in different sea lifting operations.
