In this episode of Fluid Power Forum, host Eric Lanke interviews Jon Frey, head of product area new business at Bosch Rexroth, about hydraulic motion control solutions that help “conquer the seas” by improving vessel and load stability in harsh maritime environments.
Frey explains how hydraulics power and precisely control marine systems such as winches, cranes, steering gears, thrusters, stabilizers, mooring/constant-tension control, and active heave compensation (AHC). He describes AHC as using sensors like accelerometers and motion reference units (MRUs), responsive hydraulic winches, and control algorithms—often integrated with broader vessel control architectures and dynamic positioning—to keep suspended loads (e.g., ROVs or drilling equipment) stable relative to the seabed despite wave-induced heave.
Frey also highlights design challenges including dynamic response, corrosion resistance, environmental forces, and future advances like AI/machine learning, real-time analytics, condition monitoring, and predictive maintenance.
