On a larger boat I am considering, the hydraulics are run from multiple individual electro-hydraulic units (one for rudders, one for thrusters, one for winches and one for stabilizers) instead of the more common power-takeoff from the main engines. Does anyone have a point-of-view on this? At first blush, it would appear multiple units provide greater redundancy albeit at the cost of greater maintenance. In addition, they can be operated with the generator running, instead of needing to have the motors running (worthwhile for the winches and stabilizers). I don't have info yet on the specific electro-hydraulic units but I assume they can be made at least as robust as a PTO from the main engines? Are they known to have similar MTBF? Thanks!
