  • This vessel adopts Kawasaki's uniquely developed bow shape called SEA-Arrow, which significantly improves propulsion performance by minimizing bow wave resistance.
  • The main engine powering the vessel is an energy-efficient, electronically-controlled, ultra-long-stroke, two-stroke low-speed diesel engine. In addition, the Kawasaki rudder bulb system with fins (RBS-F) and the semi-duct system with contra fins (SDS-F) contribute to reducing fuel consumption.
  • Four independent cargo tanks are installed in the cargo holds for carrying liquefied petroleum gas. The tanks are designed to provide optimal thermal insulation and absorb low-temperature contraction.
  • The cargo tanks are made with special cryogenic steel for loading LPG with a minimum temperature of –46°C. The tanks are wrapped in urethane foam for thermal insulation.
  • The vessel is designed to be fully compliant with the New Panamax requirements and is able to navigate the newly expanded Panama Canal, which was completed in June 2016.
