All-electric subsea systems with the Bosch Rexroth eSEA Portfolio
Extreme weather events, such as droughts or flooding, highlight the extent of global warming: Mitigating environmental impacts is the most urgent challenge of our generation. Safe, efficient and scalable subsea systems for new subsea industries, such as Carbon Capture, Utilization and Storage (CCUS) and offshore Green Hydrogen (H2) production, are elements to reduce the eco-impact of the energy sector. There is a need for scalable solutions to make these industries more affordable.
With the eSEA Portfolio you solve obstacles: The easy-to-use Subsea Electric Actuators operate subsea valves fully electrically, no matter if linear or rotary movements, if low or high loads. Our actuation solutions reduce CAPEX and OPEX for subsea installations by simplification of the design, with field-proven safety and reliable solutions replacing hydraulics and using only low power supply.
In a nutshell: eSEA offers a scalable and cost-effective actuator system for subsea installations in applications as CCUS and Green Hydrogen. All eSEA products are focusing on energy-efficiency, safety and simplified integration.
We move all types of subsea valves with low power
Compact, energy efficient, intelligent and with field-proven safety: The Bosch Rexroth easy-to-use Subsea Electric Actuators of the eSEA Portfolio cover all applications for subsea systems: Torque, Push and Drive, for all kinds of loads. The lean all-electric technology helps to eliminate the need for hydraulic supply and control lines. It is the perfect solution to simplify and modularize subsea installations for shorter time to market and higher reliability.
One portfolio designed to serve all applications
The eSEA portfolio is ready to be installed in greenfield and brownfield applications for offshore energy, water treatment facilities as well as for new industries such as Carbon Capture, Utilization and Storage (CCUS) and Green Hydrogen (H2) production offshore, which are seen as an essential contribution to the energy transition.

The eSEA Portfolio
The eSEA Subsea Electric Actuators cover all applications for subsea systems:
- eSEA Torque for rotary small bore valves,
- eSEA Push for linear valve actuation and
- eSEA Drive for large subsea valves.
The actuators are based on industrial components, qualified for use in depth of up to 4,000 meters and designed for permanent subsea use for over 25 years. The field-proven safety technology is using the deenergize-to-trip approach, meeting the safety requirements up to safety integrity level SIL 3. The energy efficiency minimizes effort for electric power generation and transfer throughout the lifetime. Due to standardized interfaces the lean subsea actuators are easy to integrate into greenfield and brownfield applications.
