Carbon Capture Utilization and Storage (CCUS) facilities are crucial to mitigate in industrial scale the global emissions in the next years. By the first CCUS pilot projects, the CO2 injection wells were developed using traditional hydraulic systems leading to high complex systems with considerable CAPEX and OPEX costs associated with environmental risks. On the other side, the available all-electric subsea control systems designed for the oil and gas production require a much higher CAPEX investment, being not so suitable for scaling up the CCUS.
In the design of the new electric Subsea Valve Actuator SVA R2, the drive technology was optimized to reduce its power consumption below 48W. Without the need for electric energy storage, these actuators provide a highly responsive safety function with SIL 3 based on field-proven springs. With a standardized design integrating industrial and automotive components, a lean production system is applied to ensure high quality and efficiency.
Now, this drive technology is being used in the development of a new generation of subsea electric actuators for larger rotative and linear valves, with and without safety functions, all with the low power demand. Simulations indicate that an entire subsea tree could be operated with less than 385 W without applying an expensive subsea battery. Such a system could dramatically simplify the subsea control architecture, reducing also the costs of the overall electric infrastructure needed.
This technical presentation will explain how we can scale up subsea carbon storage systems, using lean electric actuators to reduce the overall costs.
