Mitsubishi Heavy Industries (MHI) and Wartsila are teaming up to develop more powerful and efficient ship propulsion systems.

MHI's Marine Machinery & Equipment (MHI-MME) unit and the Finnish group have signed a memorandum of understanding on the marketing of a new energy solution.

The Japanese yard promises greater power generation capacity and increased propeller propulsion for marine vessels.

By integrating MHI-MME's waste heat recovery and energy saving power generation system (WHRS) with Wartsila's operational control technology for shaft generator systems, the companies says they can achieve more energy-efficient ship navigation and an improved Energy Efficiency Design Index (EEDI) rating.
