Integration of shaft generation and WHRS
[ Marine Boiler / Turbine ]

shaft generation
This solution combines MHI-MME's energy-saving power generation system with Wärtsilä SAM Electronics's operational control technology for shaft generator systems.


Shaft generator output is amplified by integration with WHRS.
This solution enable to produce greater power generation capacity and higher propeller propulsion and improve Energy Efficiency Design Index (EEDI).
