The smart ship, especially the unmanned vessel, has received increasing attention with the development of the automatic control technology and the artificial intelligence technology. Firstly, it discusses the equipment configuration and the contribution cost that can be reduced by designing the offshore chemical carrier that is the highly automated ice transport ship as the unmanned vessel, and then the instruments that should be added according to the standard of the unmanned vessel. It also carries out the economic analysis of the unmanned vessel from the possible investment cost and the operation cost, which can provide reference for the future development and the application of the unmanned ship technology..
