Hyundai Mipo Dockyard (HMD) and ILSHIN LOGISTICS have successfully delivered the world’s first LNG-fueled bulk carrier under the dual-class of Lloyd’s Register (LR) and Korean Register. The bulk carrier has also been verified to be in compliance with the International Gas Fuel (IGF) Code, and is the result of a collaboration project, announced in July 2016, to develop the first in a new generation of environmentally-friendly LNG-fueled bulk carriers.
The ship has a Type ‘C’ LNG fuel tank made of austenitic high manganese steel. The material, newly developed by POSCO, has a high manganese content 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 provided 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.
