PROPULSION GENERATORS FOR SUPERYACHTS

On a superyacht with electric or hybrid propulsion, the generator set feeds the drivetrain. Propulsion demand swings continuously: from slow maneuvering in the marina to sustained cruising load, sometimes with hotel load added on the same busbar. A generator set built for a flat load profile cannot follow that swing. What matters here is response, not just output: how quickly the set adapts as demand shifts.

Custom built

Every propulsion generator set is custom-built. Our engineering department customizes the genset from both internal architecture to external connections and flexible mounts. In early project stage, we work together with the naval architect, shipyard, the owner’s team and integrator to capture needs and requirements. Based on the briefing, we tailor each genset to fit in both new as existing machinery room layouts. With experience built up over the years, we advise on both straightforward and more technically demanding designs.

Our systems

The Zenoro marine generator covers propulsion applications in both fixed or variable speed. Zenoro matches engine, alternator, and control logic to the propulsion architecture, balancing ease of operation, total cost of ownership, and onboard guest comfort. Our gensets are equipped with a customized coupling to absorb the vibrations and transmit the torque. To further enhance the onboard comfort, our gensets can be double elastic mounted. Above 130 kWe, Zenoro equips the generator set with a Xeamos aftertreatment system as standard: DPF-only, SCR-only, or a combined DPF/SCR configuration. Below 130 kW, an aftertreatment system is available as an option.
