This paper overviews the operation and development of domestic and foreign marine weather routing service for ships based on the introduction of several marine weather routing companies and organizations. The study shows the foreign weather routing service has a long history of development with abundant technical reserves and complete operational systems, occupying the majority of the global market share of weather routing. The weather routing in China has shorter history, is weak at technology, and shares small volume of business. At present, with diversified platforms and products gradually developing under the background of informationization, the weather routing service in China is striving to innovate and good progress has been made.
