A marine GenSet designed to deliver more power with proven reliability, the 9L23/30H from MAN Energy Solutions stands out as a robust solution for modern maritime applications. This Mk. 3 version of the well-proven L23/30H family offers increased power output per cylinder, reduced fuel oil consumption, and compliance with the 2020 SOx regulations. The 9L23/30H is particularly suited for installations in engine rooms equipped with SOx scrubbers, thanks to its higher power density and efficient design. With a dry mass of 24.5 t and dimensions tailored for easy maintenance, this GenSet can be configured to run at 720 or 900 rpm, providing outputs ranging from 1,593 kW (engine) to 1,515 kW (generator) at 50 Hz, or 1,800 kW (engine) to 1,710 kW (generator) at 60 Hz. The engine’s marine head design and self-aligning bedplate installation ensure straightforward maintenance, while the SaCoSone safety and control system with an electronic speed governor enhances operational reliability. Notably, the 9L23/30H offers the longest time between overhauls (TBO) in its class, extending to 32,000 hours for the 720/750 rpm version and 20,000 hours for the 900 rpm variant.
