(Rederi AB Bur,
Rederi AB Atala,
Rederi AB Kare,
Rederi AB Ranja,
Rederi AB Disa,
Rederi AB Poseidon,
Bergnings- och Dykeri AB Neptun.)

Rederi AB Disa was formed 1898 in Gefle by O.A. Brodin. 1914 Brodin moving their operations to Stockholm, where the shipping business was run on through several subsidiaries such as Rederi Bur, Atala, Kare, Ranja and others.
The most famous of these companies were, however, Disa and Poseidon. So far I have been able to discover so had none of the companies Brodin's name, even though it was this name that was used as a unifying name for all companies.
In 1971 Brodin was bought up by the expanding SalÚn Lines that a few years earlier also become the owner of Rederi AB Rex. Together with Rex came Brodin's activities to form the basis of Salen's dry cargo.
