KRISO jointly developed large-scale fuel-saving coastal car ferry with Hanjin Heavy Industries

□ The Medium-size Ship Design & Engineering Project of the Korea Research Institute of Ships and Ocean Engineering (KRISO led by President Booki Kim) announced that it had jointly developed a large-scale eco-friendly coastal car ferry with a vertical stem design* with Hanjin Heavy Industries (Byung-mo Lee, CEO) for the first time in Korea.

* Vertical stem design: Refers to a design with no bulbous projections (protrusions) that vertically adjusts the angle of the ship bow to find optimal navigation conditions.

□ In March, the two parties signed an MOU for the joint development of a 170-m car ferry and then worked on the optimization of main specifications to achieve the two objectives of reducing the greenhouse gas (GHG) emissions from the transit draft by 30% or more and improving ship stability. The research was conducted on ship design from stem to stern with various shapes, and performance verification was then performed using model tests by KRISO.

□ So far, bulbous bow design has been applied to almost all domestic large-scale coastal car ferries. The developed ferry is the first passenger ship with the hybrid ledge bow design applied in Korea. This design allows the ship to maintain its bow structure to best suit the given draft and trim conditions while minimizing wave drag. Indeed, it turned out that, in the actual operating condition, fuel consumption was reduced by 10% or more.

□ The joint development of this best-performing large-scale car ferry by the Medium-size Ship Design & Engineering Project of KRISO and Hanjin Heavy Industries has laid the groundwork for the group to enter not only the domestic large-scale car ferry market but also the Korea-China car ferry industry. This achievement is expected to help medium-sized domestic shipbuilders, including Hanjin Heavy Industries, to diversify their ship types.

□ The Medium-size Ship Design & Engineering Project of KRISO and Hanjin Heavy Industries have expressed their will to continue their cooperation in improving the performance of domestic coastal passenger ships and developing eco-friendly ships based on this success.

□ The Medium-size Ship Design & Engineering Project of KRISO has been providing support to domestic shipbuilders and design companies in technology development, using human resources with development expertise and software infrastructure available with the help of the government and the City of Busan. By doing so, the institute is actively engaging in the advancement of medium-sized ship design technology while seeking to gain a competitive edge in technology.
