TSUNEISHI SHIPBUILDING Co., Ltd. delivered its first LPG carrier on January 31st.
The LPG tanks were entirely manufactured in-house, and molding the tank head to the edge of the pressure tank was a significant challenge. Nevertheless, this task was successfully carried out using existing equipment.
The LPG carrier installed with these tanks will retain the main dimensions of the standard 5,000m3 LPG carrier class. The vessel has a cargo tank capacity of 5,000m3, a length of 99m, a breadth of 17.6m, and a depth of 8m. Mitsui E&S Shipbuilding Co., Ltd. of the TSUNEISHI GROUP provided the expertise of tank manufacturing and gas outfitting, such as the basic design, the detailed design for the gas tank and gas system, the assembly procedure, and the precision management method.
Tsuneishi LPG carrier features a hull form that reduces propulsion resistance and the newest main engine technology to comply with the CO2 emission regulations of EEDI (*1) Phase 3. Equipped with SCR (*2), this LPG carrier qualifies as an eco-ship with excellent propulsion and environmental performance that satisfies the requirements of the NOx Tier III regulations.
*1 EEDI: The Energy Efficiency Design Index is a technical measure mandated by international treaties of the IMO (International Maritime Organization), made applicable to newly-built vessels with the aim of gauging and reducing their CO2 emissions.
*2 SCR: Selective Catalytic Reduction is an exhaust gas treatment equipment that reduces the NOx (nitrogen oxide) emissions generated by engines to a level that satisfies the requirements of the NOx Tier III regulations.
