Bosch Rexroth has developed an autonomous subsea actuator designed to improve the energy efficiency of seafloor applications , such as drilling . The product , called the Subsea Valve Actuator , has its own fluid circuit and a variable - speed pump drive , eliminating the need to use a central pumping unit or long fluid lines associated with electromechanical or electrohydraulic pumps . The company claims the technology , which uses a displacement control device to control the flow in the fluid circuit , reduces energy demand by up to 90 % at peak loads compared with purely electro - mechanical actuators .
Bosch Rexroth has developed an autonomous subsea actuator designed to improve the energy efficiency of seafloor operations, such as drilling. The product, called the Subsea Valve Actuator, has its own fluid circuit and a variable-speed pump drive, eliminating the need to use a central power unit or long fluid lines associated with electromechanical or electrohydraulic alternatives. The company claims the technology, which uses a displacement control system to adjust the flow in the fluid circuit, reduces energy demand by up to 75% at peak loads compared with purely electro-mechanical actuators.
