SANDINGE BOGSER & SJÖTRANSPORT.

The chartered Gunnfjaun was photographed on 28 June 2006 for Sandinge Bogser o Sjötransport. The source contrasts that company’s blue colour with red boot topping against Bengt Pråmkompaniet’s orange; most of the small tugs lacked funnels.

The official company account says operations began in 1971; the archive says formed in 1970. A predecessor-versus-legal-company distinction is possible but has not been established. Separate Sandinge Shipping, Star Bogser and Bengt Pråmkompaniet relationships remain unverified.
