Bosch Rexroth won the Spotlight On New Technology™ Award from the Offshore Technology Conference (OTC 2020) for its High Force and Low Voltage Subsea Valve Actuator (SVA). This groundbreaking innovation enables the implementation of the all-subsea factory in green- as well as in brownfields. The award-winning solution was recognized for its environmentally friendly setup, energy efficiency, and functional safety. Featuring a cost-effective modular design with a complete redundant drive and safety system, the solution works reliably in operating depths up to 3,000 m.
Combining the advantages of both electro-mechanical and electro-hydraulic systems in a compact electro-mechanical actuator with hydrostatic drive, the award-winning SVA proves to be a viable alternative to electro-mechanical and conventional hydraulic systems. The SVA provides up to SIL3 safety including condition monitoring, consumes up to 75% less energy, and is designed for 25 years of operation. With redundant pressure compensation, it can reliably operate in the harsh environment of subsea applications.
The electrification of previously installed subsea production systems has not been a viable option in the past, due to their demand for high-voltage power supplies. The newly designed Bosch Rexroth SVA can provide high forces to actuate the installed valves by using the available low voltage power supply – according to the Subsea Instrumentation Interface Standard (SIIS).
Highlights of the winning product include the avoidance of hydraulic leakage into the ocean, increasing productivity with a highly-reliable, safe and precise actuator, as well as new possibilities to expand brownfields with new equipment – without adding new hydraulic or electric power supplies.
