I spent the afternoon in the Norwegian national library yesterday, and I have some additional information to show for it.

In the book "75 år på Kjøtteinen: 1919-1994: Jubileumsbok for Aker Stord." - It is confirmed that Cretesurf (listed as the concrete barge "Greatsurf"[sic])was owned by AS Stord and used as a floating warehouse for Herring bone meal - and then sold shortly before world war II to interests in Bergen.

That at least tells us that Cretesurf was not lost while under tow by the Skogland boats to Brazil, which was another theory.

The backstory is also coherent with the wreck/quay in Kvamsøy - bone meal/flour is both "mel" in Norwegian, so it might be Cretesurf that's stuck up there instead of the assumed Creteravine.
