Offshore Stabilization Mount

OSM 4000 - Marine

The Offshore Stabilization Mount 4000  is the most powerful gyro-based stabilization platform ever developed by SOMAG and aims to stabilize heavy single- or multi-sensor payloads in marine settings.

OSM 4000 gyro stabilizer platform for multi-sensor systems


  • Highest payload stabilization

    of marine Gyro Stabilization Mount series
  • Highest stabilization accuracy

    of marine Gyro Stabilization Mounts series
  • Ethernet interface

    for integration in ship’s infrastructure

Hydraulic gimbal system for heavy sensor payloads

The OSM 4000 addresses the challenges of data acquisition in the most demanding maritime environments. The gyro stabilizer is equipped with high-precision built-in sensors to detect movements and automatically compensate them to keep the payload in a leveled position. In the further development of the OSM 4000 in 2021, SOMAG demonstrates its engineering capabilities and optimizes the hydraulic system in an unprecedented way. The Mount gathers power and accuracy as an incredible 300 kg (661,4 lbs) can be stabilized with a peak torque of 550 Nm to an accuracy of up to ≤0.4° rms residual deviation from perpendicular. This makes the gyro-based platform suitable for heavy single- and even multi-sensor payloads.

Gyro Stabilization for Imaging Sensors, Radars, Antennas and other payloads

The gimbal system ensures a stabilized and sharp field of view. With a mounting space of Ø600 mm the stabilization platform offers sufficient space for a wide range of large naval sensor systems deployed on frigates and other large ships. The weatherproof design (IP class 67) protects the Mount from environmental influences such as salt- and splash water, enabling flexible use in surveillance and situational awareness tasks above deck in a variety of naval and marine applications as well as on floating platforms for wind lidar stabilization or as an stabilized landing platform for UAVs.

The OSM 4000 now offers an Ethernet interface for easy integration into the surface vessel’s infrastructure. Transmission of external data such as GPS provided by the ship’s internal navigation system over a longer distance can be realized as well as the input of IMU data for improved stabilization in terms of leveling and heading accuracy.

Preliminary data, subject to change

1 Vehicle motion ≤± 12° / 12°/s / 10°/s2 – small periodical lateral accelerations (≤ 0.5 g) acceptable, constant lateral accelerations for more than 1 minute reduce the performance of the Mount (can be compensated by external GPS input)
2 Possible payload weight depends on lateral acceleration and CoG of payload / shown data is based on 0.5 g lateral acceleration and a CoG payload offset to the Mount surface of: 370 mm (14.6 in) | 450 mm (17.7 in) | 550 mm (21.7 in)
3 Maximum duration 90 s at 55 °C surrounding temperature / longer if temperature inside the unit is < 55 °C
4 Horizontal payload CoG offsets are not considered; without wind force and other possible external forces


Sharp images and a stabilized field of view despite high waves and rough weather conditions? The solution is Gyro Stabilization Mounts, developed especially for this purpose. Roll and pitch movements are reliably compensated to keep the sensor system perfectly balanced. Would you like to see in which cases SOMAG Marine Mounts are beneficial? We have compiled a number of examples for you that show the variety of application scenarios for our devices.
