  1. This vessel expanded the cargo section of the conventional 80,000 m3 LPG carrier hull to increase cargo tank capacity to 82,200 m3. Despite the expansion, the propulsion performance has also been improved.
  2. This vessel adopts Kawasaki's uniquely developed bow shape called SEA-Arrow. It significantly improves propulsion performance by minimizing bow wave resistance.
  3. 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.
  4. 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.
  5. 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.
  6. The vessel is designed to be fully compliant with the New Panamax requirements and will be able to navigate the new Panama Canal once it opens this year.
