This paper analyzes feasibility and convenience of transition from conventional oleodynamic power drives onboard liner/military ships to all-electric drives (AEDs). Classical hydrostatic transmission drives (HTDs) are cumbersome, heavy, complex, low efficiency systems and need intensive maintenance for oil leakages and filters, but feature high torque/thrust density and reliability. Alternative AEDs feature compactness, high efficiency, modularity, and better electronic control by inverter, but advantages and limits must be evaluated. High torque/redundancy requirements need special designs. Two plant types are analyzed: mooring/anchor capstans and rudder steering gears. Commercial AEDs are considered, besides a new permanent-magnet linear motor under development suitable for rudder/fin direct drive application. HTDs and AEDs are compared on the basis of encumbrance, weight, efficiency, redundancy, maintenance, complexity, modularity, reliability. Advantages of using AEDs are outlined.

Abstract
This paper analyzes feasibility and convenience of transition from conventional oleodynamic power drives onboard liner/military ships to all-electric drives (AEDs). Classical hydrostatic transmission drives (HTDs) are cumbersome, heavy, complex, low efficiency systems and need intensive maintenance for oil leakages and filters, but feature high torque/thrust density and reliability. Alternative AEDs feature compactness, high efficiency, modularity, and better electronic control by inverter, but advantages and limits must be evaluated. High torque/redundancy requirements need special designs. Two plant types are analyzed: mooring/anchor capstans and rudder steering gears. Commercial AEDs are considered, besides a new permanent-magnet linear motor under development suitable for rudder/fin direct drive application. HTDs and AEDs are compared on the basis of encumbrance, weight, efficiency, redundancy, maintenance, complexity, modularity, reliability. Advantages of using AEDs are outlined.File | Dimensione | Formato | |
