Three-Hundred Orders for Propeller Retrofit Projects

- Contributing to Sustainable Operations by Reducing Both Fuel and CO₂ Costs-

Mitsubishi Heavy Industries Marine Machinery & Equipment Co., Ltd. has reached a cumulative total of 300 propeller retrofit orders ^(*1).
Retrofitting propellers optimally designed for vessels operating at low loads can be expected to realize approximately 2-12% improvement in fuel efficiency. This not only reduces fuel costs but also helps mitigate the cost burden associated with CO₂ emissions. Discussions are ongoing within the International Maritime Organization (IMO) regarding actions towards GHG reduction. As CO₂ costs are becoming a concern for business profitability in the future, improving propulsion efficiency will be an effective measure. Our company is committed state-of art new propeller to be delivered in time, by optimizing individual vessels based on operational data and collaboration with our manufacturing operations partner in China.

We have completed the "100th propeller retrofit" project for vessels with MSC, covering a wide range of container ships from 2,000 to 23,000 TEU. This has resulted in the confirmed improvement of fuel efficiency. We expect annual reduction of approximately 487,000 tons of CO₂ ^(*2). The 100th retrofit marks an important milestone in our long-standing partnership with MSC.

We aim to leverage these achievements and insights to offer proposals to other clients, contributing to the realization of sustainable shipping by reducing fuel costs and CO₂ emissions.
