WITTENSTEIN motion control GmbH and Bosch Rexroth AG are cooperating in the field of innovative and efficient subsea technology. The joint development of an electromechanical subsea actuator enables viable business models for the production of green hydrogen at sea or the storage of CO2 under the seabed.
The new subsea actuator controls the continuously variable flow of gases and fluids at a water depth of up to 4000 meters. It is operated via a 24 V power supply. As a result of this, the valves no longer require the traditional hydraulic pipes from the water surface to the seabed. Electrification reduces both the investment costs for the entire subsea system and the operating costs in the long term compared to the existing hydraulic solution.
“This development is not only a technological achievement, but also proof of successful cooperation. By combining the expertise of WITTENSTEIN in the field of gearbox technology with the expertise of Bosch Rexroth in automation and electronics, we are developing solutions that offer real added value for our customers. Together, we are shaping the future of fully electric actuators in subsea technology,” summarizes Dr. Steffen Haack, CEO of Bosch Rexroth AG.
Product premiere at OTC 2025
The actuator will be presented for the first time at the Offshore Technology Conference (OTC) from May 5 - 8, 2025 in Houston, USA. Bosch Rexroth and WITTENSTEIN will be exhibiting together at booth #3219.
