(MES-S; President: Kenichi Shibata; Headquarters: Daiba, Minato-ku, Tokyo) developed the stern fins as a measure to improve fuel efficiency and reduce greenhouse gas (GHG) emission for MES-S built 56,000DWT Bulk Carrier*. The company has already received four orders for these products since last year, and is providing engineering support for retrofitting to existing vessels. The stern fins have been designed to enhance propulsive efficiency, with a shape optimised through Computational Fluid Dynamics (CFD) analysis for the 56BC model. This is expected to result in approximately 3% of energy savings compared to an identical vessel without the stern fin. The fins have also been designed with a very simple shape to facilitate ease of manufacturing and installation. This allows for retrofitting to be completed within the scheduled dry-docking period, without impacting the vessel\u2019s operational efficiency. The stern fins contribute to reducing both operational costs and GHG emissions. In the face of mounting environmental regulations aimed at reducing GHG emissions, the shipping industry is under pressure to enhance its energy efficiency. We are committed to contributing to the development of the maritime industry and the energy saving of vessels by expanding our installation of the stern fins for 56BC. * 56,000 DWT bulk carrier: This is our best-selling ship type, with a cumulative total of over 170 ships built.

(MES-S; President: Kenichi Shibata; Headquarters: Daiba, Minato-ku, Tokyo) developed the stern fins as a measure to improve fuel efficiency and reduce greenhouse gas (GHG) emission for MES-S built 56,000DWT Bulk Carrier*. The company has already received four orders for these products since last year, and is providing engineering support for retrofitting to existing vessels. The stern fins have been designed to enhance propulsive efficiency, with a shape optimised through Computational Fluid Dynamics (CFD) analysis for the 56BC model. This is expected to result in approximately 3% of energy savings compared to an identical vessel without the stern fin. The fins have also been designed with a very simple shape to facilitate ease of manufacturing and installation. This allows for retrofitting to be completed within the scheduled dry-docking period, without impacting the vessel\u2019s operational efficiency. The stern fins contribute to reducing both operational costs and GHG emissions. In the face of mounting environmental regulations aimed at reducing GHG emissions, the shipping industry is under pressure to enhance its energy efficiency. We are committed to contributing to the development of the maritime industry and the energy saving of vessels by expanding our installation of the stern fins for 56BC. * 56,000 DWT bulk carrier: This is our best-selling ship type, with a cumulative total of over 170 ships built.
