World’s First LNG-fueled Bulk Carrier Delivered
The ship has a Type ‘C’ LNG fuel tank with a capacity of 500m³, made of austenitic high manganese steel and located on the aft mooring deck. The material, newly developed by POSCO, has a high manganese content (approximately 26 percent) and is specially designed for cryogenic LNG and liquefied gas storage applications. The properties and characteristics of the high-manganese steel, as well as the required welding technology and fuel tank design, have been proven suitable for cryogenics with the support, certification and approval of LR.
LR said it undertook a comprehensive approach in supporting POSCO and ILSHIN LOGISTICS by providing certification of High Manganese Steel Welding Consumables, Welding Procedure Approval and Material Approval after concluding extensive development and testing. LR certification was officially issued in July 2017.
