In line with traditional Mitsubishi practices, developing a new engine begins with constructing a single-cylinder research engine (SCRE). This step-by-step approach provides valuable data, which is then applied to developing the 6-cylinder engine.

The single-cylinder test engine is then subjected to extensive testing on the test bench, conducted by TNO’s (Dutch Organization for Applied Scientific Research) leading engineers.

Our engineers designed and built the prototype based on the test results in our workshop, using the existing S6R-MPTAW engine as the foundation. By modifying the fuel injection system to run on hydrogen, we ensured minimal changes to the engine room — making the upgrade practical and user-friendly for operators and technicians.

Similar to the SCRE, the prototype engine is subjected to rigorous testing by TNO experts. Key parameters — including thermal behavior, vibration levels, acoustic emissions, fuel efficiency, power output, and torque curves — are precisely measured and analyzed. This data is critical for performance validation, durability assessment, and fine-tuning the engine for hydrogen combustion under real-world operating conditions

Koedood Marine Group, also based in the Netherlands, will build the generator. This generator powers an electric motor, which will ultimately be used for the ship's propulsion. In recent years, Koedood has gained significant experience with hydrogen, primarily in combination with fuel cells.
