Bosch Rexroth has developed an autonomous subsea actuator designed to improve the energy efficiency of seafloor operations, such as drilling. The new system is based on a novel design that uses piezoelectric materials and can be used in both deep water environments and shallow ocean environments. 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.
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.
