This paper discusses the relationship between Maritime Autonomous Surface Ship (MASS) and articles of the International Convention on Salvage 1989. The premise of the paper is that crewless operations require distinct treatment under the law of salvage. This premise is tested with reference to existing case law and articles in the Salvage Convention. It is argued that, if the operations of MASS substantially reduce the likelihood of accidents and risks associated with shipping operations, the factors for determining salvage rewards need to be revisited. It is also debated whether the present policy considerations underlying the Salvage Convention are fit to continue to apply to MASS in light of the social-political-economic changes since 1989
