forward and by realigning a non-symmetrical duct adapted to the stern flow. The MIDP increased propeller efficiency and virtually eliminated the shipyard downtime which was formerly necessary for repairing the erosion problems. The substantial fuel savings has been demonstrated in over 200 ships, including all of Exxon's Very Large Crude
Carriers. New ships have been incorporated MIDP in their design, and older ships have been retrofitted.

Narita lead the team developing the novel Mitsui
Integrated Duct Propeller (MIDP), which was designed to increase fuels saving in large ships. The MIDP effectively mitigated the constant erosion caused by cavitation from the ship's propeller on the conventional propeller duct by moving the duct

Narita developed the world's first use of the catamaran-like design for large commercial ferries—the "small waterplane area twin hull" or SWATH configuration. The demonstrated stability and seaworthiness of these ferries led to the increased use of a similar vessel design in contexts, including

In the 1990s, Narita was given broader responsibility for managing
