For environmental and economic considerations

liquefied natural gas (LNG) has gradually become the preferred alternative fuel for LNG ships. The LNG navigation safety has attracted widespread attention of various countries

and corresponding standards are issued to ensure LNG navigation safety application. The article collates and summarizes the LNG navigation standards from four technical aspects of LNG port and terminal

LNG bunkering

LNG ships and LNG transportation

introduces and analyzes the current status of international and domestic LNG navigation safety standards to describes its recent progress and focus

which provides reference for the future application and generalization of LNG inland waterways in China. At present

the focus of improving the safety of LNG navigation is on the two core areas of LNG bunkering with high accident probability and complex inland transportation. The existing standards lack definitions and safety regulations for small LNG bunkering facilities. The improvement of quantitative risk assessment methods for LNG transportation and in-port bunkering operations is a hot and difficult study point.
