This paper deals with the mechanical solutions for installation of innovative direct-drives suited for steering gears onboard ships. The work is comprised in a research project commissioned by the Italian Navy. The research aims to realize a full-electric and oil-free drive for actuation of hydraulic loads in the perspective of more 'green ships'. The electrical drives proposed are based on a fractional slot permanent magnet linear motor sized and optimized for high force and low speed operation, as required by hydraulic loads onboard ships.
