The Nessie fleet

The Nessies: Overview and History

The name “Nessie” was given to a submarine cable trencher in 1988 when an order was received to lay a telephone line from the German mainland to Sylt, an island in the North Sea off the German coast. Nessie I was specially built for the execution of the project and spontaneously given the name Nessie when someone asked what the bales of straw on the submarine cable trencher were for and was told “That´s feed for Nessie!”
