Hello Erling, nice of you to add some information to this riddle.

I have a newspaper article quoting Finn Kuhnle, CEO of Bergens Kullkompani saying that they had "...mange slike lektere. En slik lekter gikk fullastet på en mine i Trondheimsfjorden." This was compared to the Crete Joist.

I have "B.K.1" as a one of their barges, but I did not have the exact name, nor the date of the incident of the other. Thank you for that.

I believe Cretelake is a hot candidate for that barge that sank in Trøndelag - if I still subscribe to the theory that Cretesurf is now a timber quay. From the images I received from the local contacts, the sides where the name ought to be has been shorn off, which makes identification difficult. I may have to take a trip up myself and see if I can find any other traces.

I also came across in Aftenposten 15.10.1935 - Noting that the Concrete Barge DPC55 - one of the last of its kind was laying at the quay at Hjortnæsbryggen.

I'm planning a trip to the archives at Kongsberg to see if the ship registry for Porsgrunn will shed some more light on this.
