The MRU of choice for your vessels

In rough sea conditions, a few decimal points can mean the difference between the success and failure of an operation. This is why we design our MRUs with painstaking attention to detail and precision. Accurate motion measurements in Real sea conditions.

Maintenance free MRUs

Motion Reference Units traditionally are highly maintenance intensive due to regular recalibration requirements.

It is a logistical challenge to send MRUs across the world leading to high administrative and maintenance costs. For older MRUs it is increasingly difficult to get recalibration and service.

Our MRUs are

accurate, reliable, affordable and maintenance free
Easy to retrofit with any brand of existing MRUs.

Typical MRU applications for shipping

Ship Motion Monitoring

Precise motion measurements are essential for vessel digitalisation, supporting fuel optimisation, route planning, cargo safety and structural health.

Dynamic Positioning

Dynamic positioning (DP) of vessels necessitates roll and pitch compensation of the GNSS antenna to ensure accurate positioning of the ship's control point.

Active Heave Compensation

Accurate measurement of vertical motion at the crane tip or winch is crucial for the operation of Active Heave Compensated (AHC) cranes and winches.

Helideck Monitoring

Accurate measurement of roll, pitch, and heave motions is crucial for assessing the safety of helidecks during helicopter landing and take-off operations.

Motion Compensated Gangways

Accurate measurements of all 6 degrees of freedom are essential for the automatic motion control of gangways.
