The setting up of “second registries” by European governments in the 1980s was a formative moment in contemporary maritime history. Developed in an effort to counteract the growing use of offshore flags of convenience, these registries provided European shipping companies with spaces of exception from normal regulation, lifting national manning requirements and allowing for foreign labor to be hired on local wages. This article investigates the emergence of the Nordic variants, called “international ship registries” (ISRs). Employing a global perspective which focuses on the interplay between business actors, narratives, and national politics, it argues that the influence of offshore actors in shaping the Nordic developments was more pronounced than previous research suggests. The ISR policy was originally proposed to Norwegian policymakers by an offshore shipowner living in Bermuda. From there, it transferred to Denmark and Sweden, shaping their policy debates in the 1980s and 1990s.
